Camfil Pre Filters Vietnam – HVAC, AHU & Panel Pre Filters

Camfil Pre Filters Vietnam provide first-stage particulate filtration for Air Handling Units (AHU), HVAC systems, ventilation equipment, industrial facilities, commercial buildings and selected clean-air applications.

The primary function of a pre filter is to capture larger airborne particles before they reach downstream Fine Filters, Bag Filters, Compact Filters, HEPA Filters, cooling coils, heating coils and other HVAC components.

A correctly selected Camfil Pre Filter can help reduce downstream dust loading, protect valuable final filters, maintain HVAC cleanliness and support longer service life of subsequent filtration stages.

Camfil's current pre-filtration portfolio includes several Panel Filter and Pleated Filter configurations such as 30/30, 30/30 Metal, AeroPleat and AeroPleat Metal, together with other General Ventilation products that can be selected according to the required ISO 16890 performance, dimensions, airflow and pressure drop.

VIETPHAT supports customers requiring Camfil Pre Filters in Vietnam with product identification, technical selection, replacement matching and quotation based on the existing filter code, dimensions, efficiency, airflow, pressure drop, frame construction, installation location and application.

What Is a Camfil Pre Filter?

A Camfil Pre Filter is an upstream particulate filter installed before a higher-efficiency filter or sensitive HVAC component.

Its primary purpose is not necessarily to provide the highest possible filtration efficiency. Instead, it is selected to capture an appropriate portion of larger particles before those particles load the downstream filtration system.

Typical functions include:

• Capturing coarse airborne dust.
• Reducing PM10 and larger particle loading depending on tested efficiency.
• Protecting Fine Filters.
• Protecting Bag Filters.
• Protecting Compact / V-Bank Filters.
• Protecting HEPA Filters.
• Reducing dust accumulation on cooling coils.
• Reducing contamination inside AHUs.
• Supporting longer downstream filter life.

Why Pre Filtration Is Important

Installing a high-efficiency final filter without appropriate upstream filtration can expose the final filter to unnecessary coarse-dust loading.

This can potentially:

• Increase pressure drop more quickly.
• Shorten final-filter service life.
• Increase replacement frequency.
• Increase maintenance costs.
• Increase waste.
• Increase fan-energy requirements as filters load.

A well-designed pre-filtration stage can therefore contribute to the performance of the complete filtration system rather than simply functioning as an inexpensive disposable filter.

How Camfil Pre Filters Work

Air enters the HVAC or AHU system and passes through the Pre Filter before reaching downstream components.

A common configuration is:

Outdoor Air → Camfil Pre Filter → Fine Filter → Cooling Coil → Fan → Supply Air

Where a higher-efficiency final filter is required:

Outdoor Air → Pre Filter → Fine Filter → HEPA Filter → Critical Area

The actual arrangement depends on the HVAC design, application and contamination-control requirements.

Camfil Pre Filters for AHU Systems

Air Handling Units are one of the most common applications for Pre Filters.

Outdoor air entering an AHU can contain:

• Dust.
• Fibres.
• Pollen.
• Sand.
• PM10.
• PM2.5.
• PM1.
• Other airborne particles.

A Pre Filter is generally positioned near the upstream air intake to reduce larger particle loading before air reaches more sensitive components.

Protecting AHU Cooling Coils

Cooling coils can accumulate particulate contamination when upstream filtration is inadequate.

Dust deposition can contribute to:

• Coil fouling.
• Reduced heat-transfer performance.
• Increased cleaning requirements.
• Higher HVAC maintenance.
• Contamination inside the AHU.

Pre filtration can help reduce this loading, although the complete filtration strategy should be designed according to the required supply-air quality.

Camfil Pre Filters for HVAC Systems

Camfil Pre Filters can be used in General Ventilation systems serving:

• Commercial buildings.
• Office buildings.
• Shopping malls.
• Hotels.
• Hospitals.
• Factories.
• Pharmaceutical plants.
• Food factories.
• Electronics facilities.
• Data centers.
• Cleanroom AHUs.
• Warehouses.

The required pre-filter efficiency can differ significantly among these applications.

Camfil Panel Pre Filters

Panel Filters are among the most common constructions used for HVAC pre-filtration.

Camfil's current Panel Filter portfolio contains multiple families covering different efficiencies and construction types.

Depending on the product, Panel Filters can use:

• Synthetic media.
• Cotton / synthetic media.
• Glass-fibre media in selected products.
• Moisture-resistant cardboard frames.
• Metal frames.
• Other application-specific constructions.

Camfil 30/30 Pre Filter

Camfil 30/30 is one of Camfil's established pleated Panel Filter products for first-stage filtration.

Camfil currently describes 30/30 as suitable for protecting Bag Filters or V-Bank Filters and helping keep HVAC systems clean.

Current 30/30 characteristics include:

• Prefilter classification: ePM10 50%.
• Synthetic filter media.
• Water-resistant cardboard frame.
• Radial pleat construction.
• Metal grid supporting the pleats.
• Large media area.
• High dust-holding capacity.
• Optimized energy efficiency.
• Potential service life up to six months depending on application.

Camfil 30/30 Example Specification

Parameter	Example
Product	Camfil 30/30
ISO 16890	ePM10 50%
Width	595 mm
Height	595 mm
Depth	46 mm
Rated Airflow	3,400 m³/h
Initial Pressure Drop	70 Pa
Media	Synthetic
Frame	Water-resistant cardboard

This is a current manufacturer example for one 30/30 configuration. It should not be treated as a universal specification for every Camfil 30/30 filter.

Camfil 30/30 Metal Pre Filter

Camfil 30/30 Metal provides the same general pre-filtration concept in a galvanized-steel frame configuration.

Current Camfil product information lists:

• ePM10 50% pre-filter performance.
• Galvanized steel frame.
• Synthetic media.
• Large media area.
• High dust-holding capacity.
• Radial pleats supported by a metal grid.
• Maximum listed temperature of 90°C.
• Relative humidity up to 100% under stated manufacturer conditions.

Camfil 30/30 Metal Example

Parameter	Example
ISO 16890	ePM10 50%
Dimensions	592 × 592 × 48 mm
Rated Airflow	3,400 m³/h
Initial Pressure Drop	70 Pa
Frame	Metal
Media	Synthetic

The exact specification should always be confirmed against the selected article number and current Camfil datasheet.

Camfil AeroPleat Pre Filters

Camfil AeroPleat is another pleated Panel Filter family used for General Ventilation pre-filtration.

Camfil describes AeroPleat as suitable:

• As a prefilter in two-stage filtration systems.
• For small Air Handling Units.
• For rooftop HVAC equipment.
• For selected stand-alone systems.

AeroPleat products are available in multiple constructions, so performance should be checked by exact model rather than assuming every AeroPleat has the same efficiency.

Camfil AeroPleat Metal

AeroPleat Metal combines pleated filtration media with a metal frame.

Current Camfil data for selected AeroPleat Metal products identify:

• ISO Coarse 65%.
• Legacy G4 classification in the applicable product data.
• Metal frame.
• Cotton / synthetic media.
• Use as a Pre Filter for comfort air-conditioning applications.

Camfil AeroPleat Metal Example Specifications

Dimensions	ISO 16890	Legacy Class	Airflow	Initial Pressure Drop
392 × 492 × 96 mm	ISO Coarse 65%	G4	1,900 m³/h	65 Pa
287 × 592 × 96 mm	ISO Coarse 65%	G4	1,600 m³/h	65 Pa
610 × 610 × 96 mm	ISO Coarse 65%	G4	3,600 m³/h	65 Pa
305 × 610 × 96 mm	ISO Coarse 65%	G4	1,800 m³/h	65 Pa

These figures are manufacturer examples for selected AeroPleat Metal configurations rather than universal AeroPleat specifications.

Camfil 30/30 vs AeroPleat

Parameter	30/30	AeroPleat Metal Example
Filter Type	Pleated Panel	Pleated Panel
Primary Role	Pre Filtration	Pre Filtration
Example ISO 16890	ePM10 50%	ISO Coarse 65%
Media	Synthetic	Cotton / Synthetic
Frame Options	Cardboard / Metal versions	Metal for AeroPleat Metal
Typical Application	AHU / HVAC first stage	Comfort HVAC / AHU pre filtration

The correct choice depends on required efficiency, dimensions, airflow, pressure drop, dust loading and filter-bank construction.

Camfil Pre Filters and ISO 16890

Current General Ventilation Filters should preferably be evaluated using ISO 16890.

ISO 16890 classifies General Ventilation Filters according to particulate fractions including:

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

Camfil's General Ventilation portfolio includes products ranging from coarse pre-filtration to fine ePM1 filtration.

Camfil G4 Pre Filters

Many existing HVAC specifications in Vietnam still request Camfil G4 Filter or Camfil G4 Pre Filter.

G4 is a legacy classification associated with the former EN 779 standard.

Current filter selection should preferably consider the product's ISO 16890 classification where available.

For example, selected current AeroPleat Metal product data show both legacy G4 and ISO Coarse 65% information.

This should not be interpreted as a universal rule that every historical G4 filter equals ISO Coarse 65%.

G4 vs ISO Coarse

Legacy EN 779 and ISO 16890 use different test and classification methods.

Therefore, when replacing an old Camfil G4 filter, the recommended approach is to identify:

• Exact old model.
• Article number.
• Dimensions.
• Airflow.
• Pressure drop.
• Current ISO 16890 performance.

This is more reliable than performing an assumed one-to-one class conversion.

Camfil ePM10 Pre Filters

Some Camfil Pre Filters provide tested ePM10 performance rather than only ISO Coarse classification.

For example, the current Camfil 30/30 is listed as ePM10 50%.

This can provide greater fine-particle performance than a coarse-only pre-filter configuration while still serving as an upstream filtration stage.

Pre Filter Does Not Mean One Fixed Efficiency

The term Pre Filter describes the filter's position and function in the filtration system, not one fixed efficiency class.

Depending on system design, a Pre Filter can have:

• ISO Coarse performance.
• ePM10 performance.
• Other selected General Ventilation performance.

Therefore, “Camfil Pre Filter” should not automatically be interpreted as “G4 Filter.”

Camfil Pre Filters for Bag Filters

Camfil specifically positions products such as 30/30 for first-stage filtration protecting downstream Bag Filters.

A conceptual arrangement is:

Outdoor Air → 30/30 Pre Filter → Hi-Flo Bag Filter → AHU Coil → Supply Air

The upstream filter reduces coarse particle loading on the more efficient Bag Filter.

Camfil Pre Filters for V-Bank Filters

V-Bank or Compact Filters can also benefit from appropriate upstream filtration.

A possible configuration is:

Outdoor Air → Camfil Pre Filter → Camfil Compact / V-Bank Filter → HVAC System

Camfil specifically describes 30/30 as suitable for protecting Bag Filters or V-Bank Filters.

Camfil Pre Filters for HEPA Systems

Pre filtration becomes particularly important when expensive HEPA filters are installed downstream.

A conceptual critical-filtration arrangement can be:

Pre Filter → Fine Filter → HEPA Filter

Upstream filters can reduce coarse and fine particulate loading before air reaches the HEPA stage.

This can help support longer HEPA service life.

Pre Filter vs Fine Filter

Parameter	Pre Filter	Fine Filter
Main Function	Upstream particle capture	Higher-efficiency particle control
Typical Position	First Stage	Second / Final General Ventilation Stage
Typical Particle Range	Coarser particles	Finer particulate fractions
Protects	Fine / HEPA filters and HVAC	Critical areas / downstream systems
Typical Standard	ISO 16890	ISO 16890

Pre Filter vs HEPA Filter

A Pre Filter and HEPA Filter have very different functions.

Parameter	Pre Filter	HEPA Filter
Purpose	First-stage filtration	High-efficiency final filtration
Standard	ISO 16890	EN 1822 / ISO 29463
Typical Efficiency	Coarse to selected ePM classes	H13 / H14 etc.
Dust Loading	Captures upstream contamination	Protected by upstream filters

A Pre Filter should not be described as a replacement for HEPA filtration where HEPA performance is required.

Camfil Pre Filters for Cleanroom AHUs

Cleanroom HVAC systems commonly use multiple filtration stages.

A conceptual system may include:

Outdoor Air → Pre Filter → Fine Filter → AHU → HEPA / ULPA Final Filter → Cleanroom

The Pre Filter reduces loading on downstream filtration but does not itself define cleanroom classification.

ISO 14644 cleanroom class is a system-level cleanliness requirement and cannot be determined solely from the Pre Filter class.

Camfil Pre Filters for Pharmaceutical Plants

Pharmaceutical AHUs can use Pre Filters upstream of higher-efficiency filtration.

Potential functions include:

• Outdoor-air particulate control.
• AHU protection.
• Fine-filter protection.
• HEPA-filter protection.

Pre-filter efficiency alone does not establish GMP compliance.

Camfil Pre Filters for Food Factories

Food-production facilities can use Pre Filters in AHUs serving general and hygiene-controlled production areas.

Selection should consider:

• Outdoor contamination.
• Hygiene zoning.
• Product exposure.
• Downstream filtration.
• Humidity.
• Cleaning requirements.

Process-generated flour, sugar or other heavy dust can require dedicated extraction and should not automatically be handled by the HVAC Pre Filter.

Camfil Pre Filters for Hospitals

Hospital AHUs can use upstream Pre Filters to protect higher-efficiency downstream filters and HVAC components.

However, hospital filtration requirements vary according to:

• Area risk.
• Clinical function.
• Airflow design.
• Pressure relationships.
• Final filtration requirements.

No single Pre Filter specification should be applied universally throughout an entire hospital.

Camfil Pre Filters for Electronics Factories

Electronics manufacturing can require multi-stage particulate filtration.

Pre Filters can reduce incoming coarse particle loading before Fine, HEPA or ULPA filtration.

Where Airborne Molecular Contamination (AMC) is relevant, particulate Pre Filters do not replace molecular filtration.

Camfil Pre Filters for Semiconductor Plants

Semiconductor facilities can use Pre Filters in Make-Up Air Units and other upstream HVAC stages.

These filters protect more specialized downstream particulate and molecular filtration.

However:

Pre Filter ≠ HEPA / ULPA ≠ AMC molecular filter.

Each filtration stage performs a different function.

Camfil Pre Filters for Data Centers

Data-center AHUs and Make-Up Air Units can use Pre Filters to reduce outdoor dust loading before Fine Filters or molecular filtration.

Selection should consider:

• Outdoor particulate levels.
• Airflow.
• Pressure drop.
• Cooling architecture.
• Final filtration requirements.

Because data-center HVAC systems can operate continuously, filter resistance can also influence lifecycle fan-energy consumption.

Camfil Pre Filters for Commercial Buildings

Commercial AHUs serving offices, hotels, shopping malls, airports and other public buildings commonly require first-stage particulate filtration.

Pre Filters can help:

• Protect AHUs.
• Reduce coil contamination.
• Protect downstream Fine Filters.
• Reduce maintenance loading.

Camfil Pre Filters for Manufacturing Plants

Manufacturing plants can experience relatively high dust loading depending on their location and production processes.

Pre Filters can be used for general factory HVAC filtration.

However, heavy process-generated dust from grinding, cutting, powder handling or similar activities should normally be evaluated for dedicated source extraction or industrial dust collection.

A Camfil HVAC Pre Filter is not a substitute for an industrial dust collector.

Camfil Pre Filters for FCU Systems

Fan Coil Units have more limited fan static pressure than many central AHUs.

Therefore, adding a higher-resistance Pre Filter to an FCU should be evaluated carefully.

Check:

• Filter dimensions.
• Existing resistance.
• Required airflow.
• Fan capability.
• Filter-slot depth.

A filter that is suitable for a large AHU is not automatically suitable for an FCU.

Camfil Pre Filters for Outdoor Air Intakes

Outdoor-air intakes can experience variable contamination depending on location.

Potential contaminants include:

• Dust.
• Sand.
• Pollen.
• Fibres.
• Traffic-related particulate matter.
• Construction dust.
• Industrial particulate emissions.

The appropriate pre-filtration strategy should reflect the actual outdoor-air conditions.

Camfil Pre Filter Frame Materials

Depending on the product family and model, Camfil Pre Filters can use different frame materials.

Examples include:

• Moisture-resistant cardboard.
• Galvanized metal.
• Plastic in selected filter families.

Frame selection can depend on:

• Installation environment.
• Humidity.
• Mechanical requirements.
• Disposal requirements.
• Temperature.

Cardboard Frame vs Metal Frame

Parameter	Cardboard Frame	Metal Frame
Construction	Lightweight	Rigid
Example Camfil Product	30/30	30/30 Metal
Moisture Resistance	Product-specific treated board	Suitable for relevant humid environments subject to specification
Disposal / Recycling	Depends on product/material	Metal frame may be recyclable

Neither frame type is universally superior. Selection should follow the operating environment and project requirements.

Camfil Pre Filter Sizes

Camfil Panel Filters are available in multiple dimensions.

Common international full-size modules are around:

592 × 592 mm

but many other sizes are available.

Typical panel depths can include approximately:

• 48 mm class.
• 96 mm class.
• Other product-specific depths.

Never order replacement filters from a nominal size alone without checking the actual existing filter dimensions.

Nominal Size vs Actual Size

This distinction is important when purchasing replacement filters.

A filter described using a nominal size can have an actual manufactured dimension that is slightly smaller.

For quotation, VIETPHAT recommends providing actual dimensions:

Width × Height × Depth (W × H × D) in millimetres.

Why Pressure Drop Matters

Every filter creates resistance to airflow.

The resistance is normally expressed as pressure drop in Pascals (Pa).

Excessive pressure drop can:

• Reduce system airflow.
• Increase fan power.
• Change the fan operating point.
• Affect cooling or heating capacity.
• Increase energy consumption.

Therefore, a Pre Filter should not be selected solely from filtration efficiency.

Initial vs Final Pressure Drop

Initial pressure drop is the resistance of the clean filter at a specified airflow.

As particulate matter accumulates, resistance normally increases.

The final pressure drop is a maintenance or design limit used to determine when replacement may be required.

The exact recommended limit should follow the selected filter, HVAC design and manufacturer information.

Example 30/30 Final Pressure Drop Guidance

For the current Camfil 30/30 product, Camfil lists maximum final pressure-drop guidance under EN 13053 as:

Initial pressure drop + 100 Pa, or three times initial pressure drop, whichever is lower.

This is product-specific information and should not automatically be applied to every Camfil Pre Filter.

Pre Filters and Energy Consumption

HVAC fans consume energy to overcome system resistance, including filter pressure drop.

For systems operating continuously or for many hours each day, the pressure drop of both clean and loaded filters can contribute to lifecycle energy consumption.

A complete filter evaluation should therefore consider:

• Initial resistance.
• Average operating resistance.
• Dust-holding capacity.
• Service life.
• Replacement frequency.

Dust-Holding Capacity

Dust-holding capacity describes how much particulate loading a filter can accommodate under specified test or operating conditions.

A filter with greater usable media area can potentially support:

• Slower loading.
• Longer service life.
• Fewer replacements.

However, real-world service life depends heavily on actual particle concentration, airflow and operating conditions.

How Long Does a Camfil Pre Filter Last?

There is no universal service life.

Camfil currently states that the 30/30 can have a service life of up to six months depending on application.

This should not be interpreted as a guaranteed six-month replacement interval.

Actual life depends on:

• Outdoor dust concentration.
• Operating hours.
• Airflow.
• Particle characteristics.
• Filter area.
• Pressure-drop limit.
• Season.
• Construction activity nearby.
• Industrial environment.

When Should a Camfil Pre Filter Be Replaced?

Replacement decisions can consider:

• Differential pressure.
• Physical condition.
• Operating hours.
• Dust loading.
• Required system airflow.
• Manufacturer recommendations.
• Facility maintenance requirements.

Where practical, differential-pressure monitoring is preferable to replacing filters solely according to an arbitrary calendar interval.

Can Camfil Pre Filters Be Washed?

Do not assume that a Pre Filter is washable simply because it is a coarse or first-stage filter.

Pleated products such as conventional 30/30 or AeroPleat configurations should be maintained according to the manufacturer's instructions.

Only products specifically designed and documented as washable should be washed.

Improper washing can:

• Damage media.
• Change pleat geometry.
• Damage the frame.
• Alter filtration performance.

Can a Dirty Pre Filter Be Blown Clean?

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

High-pressure air can damage the media or redistribute captured particles.

Where the product is disposable, replacement according to operating condition and manufacturer guidance is normally more appropriate.

Camfil Pre Filter Replacement Vietnam

When replacing an existing Camfil Pre Filter, identify as much information as possible.

Useful information includes:

• Camfil product family.
• Article number.
• Width.
• Height.
• Depth.
• ISO 16890 class.
• Legacy G4 or other class if shown.
• Rated airflow.
• Initial pressure drop.
• Frame material.
• Quantity.

How to Identify an Unknown Camfil Pre Filter

If the model is unknown, send:

• Clear photo of the complete filter.
• Close-up photo of the product label.
• Camfil article number if visible.
• Actual W × H × D dimensions.
• AHU model.
• Existing filter arrangement.
• Required quantity.

This information can be used to narrow down the correct replacement.

Replacing a Discontinued Camfil Pre Filter

If an older Camfil product is no longer listed, replacement matching can be based on:

• Old product code.
• Old datasheet.
• Existing label.
• Dimensions.
• Efficiency.
• Airflow.
• Pressure drop.
• Frame.
• Application.

The objective should be technical compatibility rather than simply finding another filter with the same physical dimensions.

Can Another Brand Replace a Camfil Pre Filter?

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

Compare:

• Actual dimensions.
• ISO 16890 efficiency.
• Rated airflow.
• Initial pressure drop.
• Recommended final pressure drop.
• Media.
• Frame.
• Dust-holding characteristics.
• Temperature and humidity compatibility.

Same dimensions do not automatically mean equivalent performance.

Can a Higher-Efficiency Pre Filter Replace the Existing Filter?

Potentially, but the upgrade should be checked technically.

A higher-efficiency filter may increase resistance.

Before upgrading, verify:

• Required airflow.
• Existing filter pressure drop.
• New filter pressure drop.
• Available fan static pressure.
• AHU operating point.
• Downstream filter arrangement.
• Energy impact.
