Camfil Compact Filters Vietnam – Opakfil, V-Bank & Rigid HVAC Filters

Camfil Compact Filters Vietnam provide rigid, high-capacity particulate filtration for Air Handling Units (AHUs), HVAC systems, commercial buildings, manufacturing plants, hospitals, pharmaceutical facilities, food factories, electronics production, semiconductor facilities, data centers and selected clean-process applications.

Compact filters are designed to accommodate a large filtration-media area inside a relatively compact housing. Depending on the product family, Camfil compact filters can use V-shaped media packs, mini-pleat construction or deep-pleated media to provide higher filtration efficiency, high dust-holding capacity and controlled pressure drop.

Within Camfil's current international General Ventilation portfolio, compact filters include V-Bank/header-frame filters and box-type compact filters. Product families vary by market. Relevant current families include Opakfil in international markets and products such as Durafil, Aeropac and other compact-filter solutions in selected regions.

For projects in Vietnam, the exact Camfil model, article number and current regional availability should be confirmed before procurement rather than assuming that every product family listed internationally is stocked locally.

VIETPHAT supports customers requiring Camfil Compact Filters in Vietnam with product identification, technical selection, replacement matching and quotation based on ISO 16890 efficiency, dimensions, airflow, initial pressure drop, media, frame, filter-bank configuration and application requirements.

What Is a Camfil Compact Filter?

A Camfil Compact Filter is a rigid air-filter construction designed to provide a relatively large effective media area within a compact physical depth.

Unlike a flexible bag or pocket filter, a compact filter typically uses rigidly supported media packs.

Common constructions include:

• V-Bank compact filters.
• Header-frame compact filters.
• Box-type compact filters.
• Mini-pleat media packs.
• Deep-pleated compact constructions.

The V-shaped arrangement allows multiple media packs to be installed within one filter housing, increasing available filtration area without requiring long flexible pockets.

What Does V-Bank Mean?

V-Bank describes the physical arrangement of multiple filter-media packs in a V-shaped configuration.

A simplified concept is:

Airflow → V-Shaped Media Packs → Filtered Air

The V-shaped geometry helps create a large media area within a relatively compact filter depth.

Potential advantages include:

• Large filtration surface area.
• Compact installation depth.
• High airflow capability.
• Controlled pressure drop.
• High dust-holding capacity.
• Rigid construction.
• Stable operation under variable airflow.

Compact Filter Does Not Mean One Fixed Efficiency

The term Compact Filter describes construction, not a single filtration efficiency.

Depending on the specific product, compact filters may provide performance such as:

• ePM10.
• ePM2.5.
• ePM1.
• Other classifications depending on market and test standard.

Therefore, filter construction and filter efficiency should always be specified separately.

Camfil Compact Filters and ISO 16890

For General Ventilation applications, current Camfil international products commonly use ISO 16890 classification.

Relevant groups include:

• ISO Coarse.
• ePM10.
• ePM2.5.
• ePM1.

For modern specifications, ISO 16890 performance should be obtained from the current Camfil datasheet for the exact article number.

Camfil Opakfil Compact Filters

Camfil Opakfil is an important compact-filter family within Camfil's international General Ventilation portfolio.

Opakfil products use rigid compact construction designed for applications requiring high particulate filtration performance with relatively compact dimensions.

Potential applications include:

• AHUs.
• HVAC systems.
• Commercial buildings.
• Industrial ventilation.
• Hospitals.
• Pharmaceutical facilities.
• Food factories.
• Electronics facilities.
• Data centers.
• Prefiltration for HEPA installations.

Camfil Opakfil ES

Opakfil ES is a compact V-Bank air filter designed around energy efficiency, low pressure drop and extended operating life.

Current Camfil documentation identifies important characteristics including:

• Compact V-Bank construction.
• ISO 16890 ePM1 and ePM10 options.
• Low pressure drop.
• High dust-holding capacity.
• Lightweight, robust construction.
• Aerodynamic radial design.
• Moulded recycled-plastic frame.
• Extended operating-life positioning.

Camfil Opakfil ES Example Specification

One current Opakfil ES configuration provides the following reference values:

Parameter	Example Specification
Product	Opakfil ES 1070
ISO 16890	ePM10 70%
Legacy EN 779	M6
Width	592 mm
Height	592 mm
Depth	296 mm
Rated Airflow	3400 m³/h
Initial Pressure Drop	60 Pa

These values apply to the referenced configuration and should not be treated as universal specifications for all Opakfil ES products.

Camfil Opakfil ePM1 Compact Filters

The Opakfil ES family also includes selected ePM1 configurations.

ePM1 filtration is relevant where improved control of fine particulate matter is required.

Potential applications include:

• Urban commercial buildings.
• Hospitals.
• Pharmaceutical facilities.
• Food manufacturing.
• Electronics production.
• Data centers.
• Industrial buildings.
• Cleanroom prefiltration.

What Does ePM1 Mean?

ePM1 is an ISO 16890 classification associated with filter efficiency against the PM1 particle-size fraction.

For example:

• ePM1 50%.
• ePM1 60%.
• ePM1 70%.
• ePM1 80%.

indicate different tested performance levels within the ISO 16890 framework.

The exact percentage should be taken from the current product datasheet.

Is ePM1 the Same as HEPA?

No.

ISO 16890 ePM1 filters and HEPA filters belong to different filtration-performance frameworks.

General ventilation filters are commonly classified under:

ISO 16890

while HEPA and ULPA filters are commonly classified according to:

• EN 1822.
• ISO 29463.

An ePM1 compact filter should therefore not be described as HEPA unless the specific product is separately tested and classified as HEPA.

Camfil Compact Filters and Legacy M6 / F7 / F8 / F9

Older HVAC specifications frequently use the former EN 779 classes:

• M6.
• F7.
• F8.
• F9.

These legacy classifications can still appear on old drawings, filter schedules and existing product labels.

For new specifications, current ISO 16890 performance should preferably be used.

There is no universal exact one-to-one conversion between M6/F7/F8/F9 and ISO 16890 ePM10/ePM2.5/ePM1.

Is an F9 Compact Filter a HEPA Filter?

No.

Legacy F9 is a former EN 779 fine-filter classification.

It should not be confused with HEPA classes such as:

• H13.
• H14.

A compact F9-style general ventilation filter and an H13/H14 HEPA filter perform different filtration roles and are classified under different test standards.

Camfil Compact Filter vs Bag Filter

Parameter	Compact Filter	Bag / Pocket Filter
Construction	Rigid V-Bank / Box	Flexible pockets
Media Arrangement	Rigid mini-pleat packs	Multiple bags/pockets
Typical Depth	Compact	Longer pocket depth
Airflow Stability	Rigid geometry	Flexible pockets
Dust Holding	High, product-dependent	High, product-dependent
Camfil Example	Opakfil ES	Hi-Flo

Camfil Compact Filter vs Panel Filter

Panel filters typically use shallower construction and are commonly used for first-stage filtration.

Compact filters can provide substantially more media area and higher particulate efficiency.

A common filtration arrangement is:

Panel Prefilter → Compact Fine Filter

For example:

Camfil 30/30 → Camfil Opakfil ES

where technically appropriate.

Camfil Compact Filter vs HEPA Filter

Parameter	Compact General Ventilation Filter	HEPA Filter
Typical Standard	ISO 16890	EN 1822 / ISO 29463
Typical Performance	ePM10 / ePM1	HEPA class
Main Application	HVAC fine filtration	Critical final filtration
Typical Position	Second stage / final HVAC stage	Final or terminal stage
HEPA Protection	Can serve as prefilter	Final high-efficiency stage

Camfil Compact Filters as HEPA Prefilters

Camfil identifies compact filters as suitable for prefiltration in HEPA installations.

A multi-stage arrangement can be:

Coarse Panel Filter → Compact ePM1 Filter → HEPA Filter

This arrangement can reduce particulate loading on the downstream HEPA filter.

Potential benefits include:

• Longer HEPA service life.
• Reduced HEPA dust loading.
• More stable pressure-drop development.
• Potentially lower replacement cost.
• Improved system cleanliness.

Camfil Compact Filters for AHU Systems

AHUs are a major application for compact filters.

A typical AHU filtration arrangement may be:

Outdoor Air → Camfil Panel Prefilter → Camfil Compact Filter → Coil → Fan → Supply Air

Depending on system design, the compact filter can function as:

• Second-stage filter.
• Main fine filter.
• Final general-ventilation filter.
• HEPA prefilter.

Why Use Compact Filters in AHUs?

Potential advantages include:

• Large media area.
• Rigid construction.
• High dust-holding capacity.
• Compact physical depth.
• Fine-particle filtration.
• Controlled pressure drop.
• Compatibility with multi-stage HVAC systems.

Camfil Compact Filters for HVAC Systems

Compact filters can be used in:

• Central air-conditioning systems.
• AHUs.
• Make-up air units.
• Rooftop units.
• Industrial ventilation.
• Recirculation systems.
• Selected exhaust-air systems.

Selection should consider the complete HVAC airflow and available fan static pressure.

Camfil Compact Filters for Commercial Buildings

Potential applications include:

• Office buildings.
• Hotels.
• Shopping malls.
• Airports.
• Schools.
• Public buildings.
• Retail facilities.

Higher-efficiency ePM1 compact filters can be useful where fine outdoor particulate matter is an important indoor-air-quality concern.

Camfil Compact Filters for Hospitals

Compact filters can be used as intermediate or final general-ventilation filtration stages in healthcare HVAC systems.

A conceptual filtration sequence may include:

Prefilter → Compact Fine Filter → HEPA where required

However, healthcare filtration requirements depend on the specific room and HVAC design.

HEPA filtration is not automatically required in every hospital space, and a compact filter should not be treated as a substitute for HEPA where HEPA performance is specified.

Camfil Compact Filters for Pharmaceutical Plants

Pharmaceutical HVAC systems may use compact filters upstream of terminal or AHU HEPA filtration.

For example:

Panel Prefilter → ePM1 Compact Filter → HEPA Filter

where supported by the validated system design.

The compact filter can help reduce loading on the HEPA stage.

However, filter efficiency alone does not establish GMP compliance.

Pharmaceutical contamination control also involves:

• Room classification.
• Pressure cascade.
• Airflow pattern.
• Temperature.
• Relative humidity.
• Cleaning strategy.
• Qualification.
• Validation.

Camfil Compact Filters for Cleanrooms

Camfil identifies compact filters as suitable for preparatory filtration in cleanroom applications.

A compact ePM1 filter can reduce particle loading before HEPA or ULPA stages.

However:

ePM1 compact filter ≠ HEPA filter ≠ ULPA filter.

They perform different roles within the contamination-control system.

Compact Filters and ISO 14644

A Camfil compact filter does not by itself determine the ISO 14644 classification of a cleanroom.

Cleanroom classification depends on measured airborne particle concentration within the controlled environment.

Other important factors include:

• HEPA/ULPA final filtration.
• Airflow distribution.
• Room pressure.
• Air-change strategy.
• Leakage control.
• Process contamination.
• Personnel.
• Cleaning procedures.

Camfil Compact Filters for Food Factories

Food-production facilities can use compact filters for higher-efficiency HVAC particulate control.

Applications may include:

• Production rooms.
• Packaging areas.
• High-care zones.
• Ingredient preparation areas.
• Make-up air systems.
• Selected hygienic HVAC applications.

The required filtration level should be determined according to hygiene zoning, process exposure and risk assessment.

There is no universal requirement that every food-production area use the same compact-filter or HEPA configuration.

Camfil Compact Filters for Electronics Factories

Electronics manufacturing can require enhanced particulate control to protect:

• Products.
• Processes.
• Production equipment.
• Controlled environments.

Compact ePM1 filters can provide an intermediate particulate-filtration stage upstream of HEPA or ULPA filters where required.

Camfil Compact Filters for Semiconductor Plants

Semiconductor HVAC and cleanroom systems can use compact filters for preparatory particulate filtration.

It is important to distinguish:

• Compact ePM1 filtration.
• HEPA filtration.
• ULPA filtration.
• AMC molecular filtration.

These technologies target different contamination categories.

A compact particulate filter does not replace target-specific molecular filtration for airborne molecular contamination (AMC).

Camfil Compact Filters for Data Centers

Data-center HVAC systems can use compact filters where higher-efficiency particulate control is required.

Selection should consider:

• Outdoor particulate pollution.
• Airflow requirements.
• Cooling architecture.
• Fan static pressure.
• Economizer operation.
• Required indoor cleanliness.
• Filter energy consumption.

If corrosive gases are a concern, particulate compact filtration may need to be combined with appropriate molecular filtration.

Compact Particulate Filters vs Molecular Filters

Filter Type	Primary Target
Opakfil / particulate compact filter	Airborne particles
Activated-carbon / molecular filter	Selected gases, VOCs and odors
CityCarb combination filter	Particles + selected molecular contaminants

Conventional particulate compact filters should not be expected to remove VOCs, odors or corrosive gases.

Camfil CityCarb Compact Filters

In selected markets, Camfil CityCarb is offered as a compact V-Bank combination filter.

Unlike a conventional particulate-only compact filter, CityCarb combines:

Particulate Filtration + Molecular Filtration

Current Camfil information identifies CityCarb products for contaminants such as selected:

• VOCs.
• Ozone.
• NO₂.
• SO₂.
• Organic acids.

Molecular performance should be evaluated using appropriate product-specific test data rather than assuming all activated-carbon filters perform identically.

Camfil Compact Filters for Manufacturing Plants

Manufacturing facilities can use compact filters in general HVAC systems for improved fine-particle control.

Potential applications include:

• Production-area AHUs.
• Control rooms.
• Equipment rooms.
• Quality-control areas.
• Packaging rooms.
• Make-up air systems.

However, a compact HVAC filter is not a replacement for a dedicated process dust collector where manufacturing processes generate high concentrations of dust, smoke, fumes or mist.

Camfil Compact Filters and PM2.5

Fine particulate pollution is an important concern in many HVAC applications.

For PM-related filtration, filter selection should be based on tested ISO 16890 performance rather than marketing descriptions alone.

Where fine-particle control is important, an appropriate ePM1 or ePM2.5 filter may be selected based on the system requirements.

Camfil Compact Filters and PM1

PM1 represents very fine airborne particulate matter.

Selected Camfil compact filters classified as ePM1 are specifically tested under ISO 16890 for performance against this particle fraction.

The exact ePM1 percentage should be specified.

For example, simply requesting an “ePM1 filter” is less precise than requesting the required tested ePM1 efficiency.

Camfil Compact Filter Media

Depending on product family and region, Camfil compact filters can use media such as:

• Glass-fibre media.
• Synthetic media.
• Combination particulate and activated-carbon media.

The media should be selected according to filtration efficiency, airflow, pressure-drop requirements and application.

Camfil Compact Filter Frames

Compact-filter frame materials vary according to product family.

Examples can include:

• Moulded plastic.
• Recycled plastic.
• Galvanized steel.
• High wet-strength board in selected box-type designs.

Frame material should not be used as a substitute for evaluating actual filtration performance.

Why Use a Plastic V-Bank Frame?

A moulded plastic V-Bank frame can provide:

• Low filter weight.
• Rigid media-pack support.
• Corrosion resistance.
• Aerodynamic geometry.
• Consistent media-pack positioning.

Some current Camfil products use recycled plastic to reduce material impact while maintaining structural performance.

Camfil Compact Filter Sizes

Compact filters are available in multiple frontal dimensions and depths.

A common full-size international format is approximately:

592 × 592 mm

with product-specific depth such as approximately:

296 mm

for selected Opakfil configurations.

Other full, half and special sizes are available depending on product family.

Always confirm the exact article number and actual dimensions.

Nominal Size vs Actual Size

A nominal “600 × 600” compact filter may not physically measure exactly 600 × 600 mm.

Actual dimensions may be around 592 × 592 mm depending on the product and frame standard.

Using nominal dimensions without checking the actual filter can result in:

• Installation problems.
• Poor gasket compression.
• Air bypass.
• Filter-bank leakage.

Camfil Compact Filter Airflow

Every compact filter should be selected for the required airflow.

For example, the referenced Opakfil ES 1070 full-size configuration is rated at approximately 3400 m³/h.

Other sizes and efficiencies may have different rated airflow.

Do not assume every 592 × 592 mm compact filter has identical airflow capability.

Camfil Compact Filter Pressure Drop

Pressure drop is one of the most important parameters when selecting a compact filter.

It directly affects:

• Fan static pressure.
• System airflow.
• Fan energy.
• HVAC operating cost.

For example, the referenced Opakfil ES 1070 ePM10 70% configuration has an initial pressure drop of approximately 60 Pa at 3400 m³/h.

Different efficiencies and configurations will have different values.

Why Low Pressure Drop Matters

HVAC fans must overcome filter resistance continuously while the system operates.

Therefore, pressure drop can have a significant effect on energy consumption over the filter's service life.

A technically appropriate filter should balance:

• Required filtration efficiency.
• Initial pressure drop.
• Average operating pressure drop.
• Dust-holding capacity.
• Service life.
• Fan energy.

High Dust-Holding Capacity

High dust-holding capacity can allow a filter to remain in service longer before reaching its replacement condition.

However, actual service life depends on:

• Dust concentration.
• Particle-size distribution.
• Airflow.
• Operating hours.
• Upstream prefiltration.
• Allowable final pressure drop.

No single service-life figure should be assumed for every installation.

Should a Prefilter Be Installed Before a Compact Filter?

In many applications, yes.

A typical arrangement is:

Panel Prefilter → Compact Filter

Using an appropriate upstream prefilter can reduce coarse dust loading on the compact filter.

This can potentially:

• Extend compact-filter life.
• Reduce dust accumulation.
• Improve lifecycle economics.
• Protect higher-cost filtration media.

Camfil 30/30 + Opakfil Filtration System

One possible Camfil multi-stage configuration is:

Camfil 30/30 Prefilter → Camfil Opakfil Compact Filter

The 30/30 captures larger particles upstream while Opakfil provides higher-efficiency particulate filtration downstream.

The exact combination should be selected according to required efficiency, outdoor-air quality, airflow and AHU fan capability.

Camfil Compact Filter Energy Consumption

Air filters do not normally consume electricity directly, but the HVAC fan consumes energy to overcome filter resistance.

Filter energy evaluation therefore considers:

• Airflow.
• Initial pressure drop.
• Average pressure drop.
• Operating hours.
• Fan efficiency.
• Filter loading profile.

Low-pressure-drop compact filters can help reduce fan-energy requirements when correctly matched to the system.

Camfil Compact Filter Lifecycle Cost

The purchase price is only one component of filter cost.

Total lifecycle cost can include:

• Filter purchase.
• Fan energy.
• Replacement frequency.
• Maintenance labor.
• Disposal.
• System downtime.
• Downstream-filter life.

A filter with a lower purchase price does not necessarily have the lowest total operating cost.

When Should a Camfil Compact Filter Be Replaced?

Where practical, replacement should consider differential pressure and system performance.

Replacement may be appropriate when:

• Recommended final pressure drop is reached.
• Airflow can no longer be maintained.
• The filter is damaged.
• Filter seals or frame are compromised.
• Hygiene or process requirements require replacement.
• A validated maintenance criterion is reached.

There is no universal replacement interval applicable to every Camfil compact filter.

Why Differential Pressure Monitoring Is Useful

A differential-pressure gauge or sensor measures pressure before and after the filter.

This provides information about filter resistance as dust accumulates.

Compared with arbitrary calendar replacement, differential-pressure monitoring can provide a more useful basis for maintenance in many HVAC systems.

Can Camfil Compact Filters Be Washed?

Conventional fine compact filters should generally be treated as disposable unless the specific Camfil product is explicitly designed as washable.

Washing can:

• Damage fine filter media.
• Alter filtration performance.
• Damage separators or seals.
• Create media defects.
• Increase bypass risk.

Can Camfil Compact Filters Be Blown Clean?

Compressed-air cleaning should not automatically be used on disposable fine compact filters.

High-pressure air can damage media and may not restore the original filtration characteristics.

Follow the maintenance instructions for the exact Camfil product.

Camfil Compact Filter Replacement Vietnam

When replacing an existing Camfil compact filter, collect:

• Camfil model.
• Article number.
• ISO 16890 efficiency.
• Legacy class if shown.
• Width × height × depth.
• Rated airflow.
• Initial pressure drop.
• Frame type.
• Gasket configuration.
• Application.
• Quantity.

How to Identify an Unknown Camfil Compact Filter

If the original label or article number is unavailable, provide:

• Photo of the complete filter.
• Photo of remaining label information.
• Exact dimensions.
• Number of V-shaped media packs.
• Frame type.
• Gasket location.
• AHU model.
• Existing prefilter.
• Application.
• Quantity.

This information can help narrow the technically suitable replacement.

Dimensions Alone Are Not Enough

Two compact filters with the same external dimensions may have different:

• ISO 16890 efficiency.
• Media area.
• Pressure drop.
• Rated airflow.
• Dust-holding capacity.
• Frame construction.
• Gasket arrangement.

Therefore, replacement selection should not rely on dimensions alone.

Can Another Brand Replace a Camfil Compact Filter?

A technically compatible alternative may be evaluated where brand substitution is permitted.

Comparison should include:

• Actual dimensions.
• ISO 16890 classification.
• Rated airflow.
• Initial pressure drop.
• Dust-holding performance.
• Media.
• Frame.
• Gasket.
• Installation method.

An apparently similar V-Bank construction does not automatically establish equivalent performance.

Can an Existing Compact Filter Be Upgraded to Higher Efficiency?

Potentially, but the AHU should first be evaluated.

A higher-efficiency filter can change system resistance.

Before upgrading, check:

• Existing airflow.
• Fan static pressure.
• Current filter pressure drop.
• Proposed filter pressure drop.
• Ventilation requirement.
• Cooling and heating performance.

The objective is to improve filtration without unintentionally reducing required system airflow.

How to Select Camfil Compact Filters Vietnam
