Camfil Energy Efficient Air Filters Vietnam – Low Pressure Drop HVAC Filtration

Camfil Energy Efficient Air Filters Vietnam are designed to provide the required particulate filtration performance while helping reduce airflow resistance, HVAC fan energy, filter replacement frequency and total lifecycle cost.

In an HVAC system, an air filter does not normally consume electrical energy directly. Instead, the supply or return fan consumes energy to overcome the resistance created by filters, coils, ducts, dampers and other system components. For this reason, the pressure drop across an air filter can have a significant influence on HVAC energy consumption.

An energy-efficient air filter therefore should not simply be understood as a filter with the lowest initial pressure drop. A technically appropriate solution should balance:

• Required filtration efficiency.
• Initial pressure drop.
• Pressure-drop development during dust loading.
• Average operating pressure drop.
• Dust-holding capacity.
• Required airflow.
• Service life.
• Replacement frequency.
• Fan energy.
• Maintenance cost.
• Total Cost of Ownership (TCO).

Relevant Camfil solutions include Opakfil ES and Opakfil ES+ compact V-Bank filters for energy-conscious General Ventilation applications. Depending on the specific product and regional portfolio, Camfil also provides energy-efficient bag, pocket, panel and other compact filter solutions.

VIETPHAT supports customers requiring Camfil Energy Efficient Air Filters in Vietnam with product identification, technical selection, replacement matching and quotation based on ISO 16890 efficiency, dimensions, airflow, initial pressure drop, operating pressure drop, media, filter construction and application requirements.

What Is an Energy Efficient Air Filter?

An energy efficient air filter is an air filter engineered to achieve the required filtration efficiency while minimizing unnecessary airflow resistance and maintaining suitable dust-holding capacity and service life.

The objective is not simply:

Lowest Pressure Drop

but rather:

Required Air Quality + Controlled Pressure Drop + Long Service Life + Low Lifecycle Energy

This distinction is important because reducing filtration efficiency simply to obtain a lower pressure drop may reduce air-quality performance.

Why Air Filters Affect HVAC Energy Consumption

Air must pass through the filter whenever the HVAC system operates.

The filter creates resistance to airflow, normally expressed as pressure drop in Pascal (Pa).

The fan must provide enough pressure to overcome this resistance.

In simplified terms:

Higher Pressure Drop → More Fan Work → Potentially Higher Energy Consumption

and:

Lower Pressure Drop → Less Fan Resistance → Potential Energy Savings

provided that required airflow and filtration efficiency are maintained.

Air Filter Pressure Drop Explained

Pressure drop is the difference in air pressure measured before and after the filter.

For example:

Upstream Pressure – Downstream Pressure = Filter Differential Pressure

Pressure drop generally increases as a particulate filter accumulates dust.

This means energy evaluation should consider not only the pressure drop of a clean filter but also its resistance throughout its operating life.

Initial Pressure Drop vs Average Pressure Drop

Parameter	Meaning
Initial Pressure Drop	Resistance of the clean filter at specified airflow
Operating Pressure Drop	Actual resistance during service
Final Pressure Drop	Defined replacement or operating limit
Average Pressure Drop	Average resistance over the filter operating period

For energy analysis, average operating resistance can be more meaningful than initial pressure drop alone.

Camfil Energy Efficient Air Filter Technology

Camfil develops General Ventilation filters with design features intended to combine particulate efficiency with controlled airflow resistance.

Depending on the product family, relevant design factors can include:

• Large effective media area.
• Optimized pleat geometry.
• Controlled media spacing.
• Aerodynamic filter construction.
• V-Bank geometry.
• Optimized pocket design.
• High dust-holding capacity.
• Low-resistance filter media.

Camfil Opakfil ES

Camfil Opakfil ES is one of the key Camfil product families for energy-efficient General Ventilation filtration.

It is a rigid compact V-Bank filter designed to combine:

• High filtration efficiency.
• Low pressure drop.
• High dust-holding capacity.
• Long operating life.
• Reduced energy consumption.
• Reduced replacement frequency.
• Improved Total Cost of Ownership.

Camfil Opakfil ES V-Bank Design

Opakfil ES uses multiple filter-media packs arranged in a compact V-shaped configuration.

This provides a large effective media area within a relatively compact installation depth.

Camfil also uses an aerodynamic radial design intended to improve airflow through the filter.

Potential advantages include:

• Controlled air velocity through the media.
• Lower airflow resistance.
• High dust capacity.
• Compact AHU installation.
• High nominal airflow.

Camfil Opakfil ES Energy Performance

Current Camfil product information provides energy-performance data for selected full-size Opakfil ES configurations.

Product	ISO 16890	Dimensions	Airflow	Initial DP	Reference Energy	Eurovent Class
Opakfil ES7	ePM1 60%	592 × 592 × 296 mm	3400 m³/h	65 Pa	838 kWh/year	A+
Opakfil ES8	ePM1 70%	592 × 592 × 296 mm	3400 m³/h	75 Pa	1020 kWh/year	A
Opakfil ES9	ePM1 80%	592 × 592 × 296 mm	3400 m³/h	90 Pa	1212 kWh/year	A

The values above are manufacturer reference values for the specified configurations and test/rating conditions. Actual HVAC energy consumption depends on airflow, operating hours, fan efficiency, system control, dust loading and installation conditions.

Camfil Opakfil ES7 – ePM1 60%

The referenced full-size Opakfil ES7 provides:

• ISO 16890: ePM1 60%.
• Legacy EN 779: F7.
• Dimensions: 592 × 592 × 296 mm.
• Rated airflow: 3400 m³/h.
• Initial pressure drop: approximately 65 Pa.
• Reference energy: approximately 838 kWh/year.
• Referenced Eurovent energy class: A+.

This makes the ES7 relevant where ePM1 60% filtration and low operating resistance are required.

Camfil Opakfil ES8 – ePM1 70%

The referenced full-size Opakfil ES8 provides:

• ISO 16890: ePM1 70%.
• Legacy EN 779: F8.
• Dimensions: 592 × 592 × 296 mm.
• Rated airflow: 3400 m³/h.
• Initial pressure drop: approximately 75 Pa.
• Reference energy: approximately 1020 kWh/year.
• Referenced Eurovent energy class: A.

Camfil Opakfil ES9 – ePM1 80%

The referenced full-size Opakfil ES9 provides:

• ISO 16890: ePM1 80%.
• Legacy EN 779: F9.
• Dimensions: 592 × 592 × 296 mm.
• Rated airflow: 3400 m³/h.
• Initial pressure drop: approximately 90 Pa.
• Reference energy: approximately 1212 kWh/year.
• Referenced Eurovent energy class: A.

This example also illustrates an important principle: higher filtration efficiency can require additional airflow resistance, so efficiency and energy performance should be evaluated together.

Camfil Opakfil ES6 – ePM10 70%

For applications that do not require ePM1 performance, selected Opakfil ES configurations provide ePM10 filtration.

A referenced full-size configuration provides:

• ISO 16890: ePM10 70%.
• Legacy class: M6.
• Dimensions: 592 × 592 × 296 mm.
• Airflow: 3400 m³/h.
• Initial pressure drop: approximately 60 Pa.
• Reference energy: approximately 770 kWh/year.
• Referenced Eurovent class: B.

The correct efficiency should be selected according to the air-quality requirement rather than choosing a lower class solely to reduce resistance.

Camfil Opakfil ES+

Camfil Opakfil ES+ extends the energy-efficiency concept through a deeper V-Bank construction.

Camfil states that the additional depth provides:

• Greater effective filtration capacity.
• Improved energy performance.
• Longer operating life.
• High dust-holding capacity.
• Reduced filter-change frequency.
• Reduced waste.
• Potentially improved Total Cost of Ownership.

Opakfil ES+ and Extended Filter Life

Camfil currently states that Opakfil ES+ can last up to 70% longer than Opakfil ES in an HVAC system under the manufacturer's stated basis.

The actual service life in a Vietnam installation will depend on:

• Outdoor-air pollution.
• Dust concentration.
• Operating hours.
• Airflow.
• Upstream prefiltration.
• Humidity and environmental conditions.
• Replacement pressure-drop criterion.

Therefore, the “up to 70%” value should not be interpreted as a guaranteed service-life increase for every installation.

Opakfil ES vs Opakfil ES+

Parameter	Opakfil ES	Opakfil ES+
Construction	Compact V-Bank	Deeper premium V-Bank
Energy Focus	Very high	Enhanced
Pressure Drop	Low	Optimized for energy performance
Dust Capacity	High	Higher capacity potential
Service Life	Extended	Further extended
Filter Depth	Standard compact depth	Increased depth
Main Objective	Energy + filtration + TCO	Enhanced life + energy + TCO

What Is Eurovent Energy Classification?

Eurovent provides an energy-performance rating methodology for General Ventilation air filters.

The purpose is to help users compare filters not only by particulate efficiency but also by energy-related performance.

Depending on the applicable current rating scheme, filter testing considers performance over a defined test procedure rather than looking only at the clean-filter pressure drop.

This is important because two filters with similar initial pressure drop can develop resistance differently as they accumulate dust.

Why Energy Class Matters

Energy classification can provide a useful standardized comparison between technically comparable General Ventilation filters.

However, the energy label should not be considered in isolation.

Filter selection must also consider:

• ISO 16890 efficiency.
• Required air quality.
• Airflow.
• Dust environment.
• Service life.
• AHU design.
• Total lifecycle cost.

Energy Efficient Air Filters and ISO 16890

Energy efficiency should not replace filtration-efficiency requirements.

For General Ventilation, the filter still needs to provide the required performance under ISO 16890.

Relevant classifications include:

• ePM10.
• ePM2.5.
• ePM1.

A filter with very low pressure drop but insufficient particulate efficiency is not necessarily an appropriate energy-efficient solution.

ePM1 and Energy Efficiency

ePM1 filtration targets the PM1 particulate fraction under ISO 16890.

Applications may require different levels such as:

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

depending on the tested product and required air quality.

Higher efficiency can increase resistance, so the objective is to identify a filter design that delivers the required ePM1 performance at favorable lifecycle pressure drop.

Energy Efficient Filter Does Not Mean Low Efficiency

A common misconception is that reducing HVAC energy requires reducing filter efficiency.

This is not necessarily correct.

Modern filter engineering can use:

• More media area.
• Optimized pleats.
• Aerodynamic geometry.
• Lower-resistance media.
• Improved airflow distribution.

to reduce resistance while maintaining the required particulate performance.

Energy Efficient Filter vs Standard Filter

Parameter	Energy-Efficient Selection	Poorly Optimized Selection
Filtration Efficiency	Matched to requirement	May be selected only by price
Initial DP	Controlled	May be higher
Loading Curve	Considered	Often ignored
Dust Capacity	Considered	May be limited
Fan Energy	Evaluated	Often ignored
Service Life	Lifecycle approach	Purchase-price approach
TCO	Important selection criterion	Often not evaluated

Why Initial Pressure Drop Alone Is Not Enough

Suppose Filter A begins at a slightly lower resistance than Filter B.

If Filter A loads rapidly and develops a much higher pressure drop during operation, it may consume more fan energy over its service life.

Therefore, an energy evaluation should ideally consider the complete pressure-drop development curve rather than only the initial value.

Air Filter Energy and Fan Power

At a conceptual level, fan power is related to:

Airflow × Pressure Requirement ÷ Fan/System Efficiency

This means that increasing filter pressure drop increases the pressure the fan must provide when airflow is maintained.

Actual electrical consumption depends on:

• Airflow.
• Filter resistance.
• Total system resistance.
• Fan efficiency.
• Motor efficiency.
• Variable-speed control.
• Operating hours.

Energy Efficient Filters for AHU Systems

AHUs are a major application for energy-efficient filtration because filters operate whenever the air-handling system is running.

A typical arrangement may be:

Outdoor Air → Prefilter → Energy-Efficient ePM1 Filter → Coil → Fan → Supply Air

Depending on system design, an Opakfil ES or another suitable Camfil filter can function as:

• Second-stage filtration.
• Fine filtration.
• Final General Ventilation filtration.
• HEPA prefiltration.

Energy Efficient Filters for HVAC Systems

Potential applications include:

• Central air-conditioning systems.
• AHUs.
• Make-up air units.
• Commercial ventilation systems.
• Industrial HVAC.
• Recirculation systems.

Energy savings should be evaluated at system level because the filter represents only one component of total HVAC resistance.

Energy Efficient Filters for Commercial Buildings

Commercial buildings often operate HVAC systems for thousands of hours per year.

Applications include:

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

In long-operating-hour applications, even moderate reductions in average filter resistance can potentially contribute to meaningful lifecycle energy savings.

Energy Efficient Filters for Hospitals

Hospitals require both air-quality performance and reliable HVAC operation.

Energy-efficient General Ventilation filters can be considered for appropriate stages such as:

Prefilter → ePM1 Filter → HEPA where required

However, energy reduction should never compromise required healthcare filtration or infection-control performance.

HEPA filtration is not universally required in every hospital area.

Energy Efficient Filters for Pharmaceutical Plants

Pharmaceutical facilities can use low-resistance upstream filters to help protect more expensive final HEPA filters.

A conceptual arrangement may include:

Prefilter → Energy-Efficient ePM1 Filter → H13/H14 HEPA

Potential benefits include:

• Reduced HEPA dust loading.
• Longer final-filter service life.
• Controlled AHU pressure drop.
• Potential reduction in fan-energy demand.

Filter energy efficiency does not replace GMP contamination-control, qualification or validation requirements.

Energy Efficient Filters for Cleanrooms

Cleanroom air systems can have high airflow rates and long operating hours, making pressure-drop management particularly important.

A conceptual filtration train can be:

Prefilter → Low-Resistance ePM1 Filter → HEPA / ULPA → Cleanroom

Upstream energy-efficient filtration can help protect terminal filters while minimizing unnecessary resistance.

The cleanroom ISO class is determined by complete room performance, not by the upstream filter class alone.

Energy Efficient Filters for Electronics Factories

Electronics facilities may operate high-volume air-handling systems continuously or for extended production periods.

Energy-efficient particulate filtration can help balance:

• Process cleanliness.
• Fine-particle control.
• Airflow.
• Fan energy.
• Filter service life.

Energy Efficient Filters for Semiconductor Facilities

Semiconductor facilities can have very high air-recirculation requirements, so pressure-drop optimization can be important.

However, different contaminants require different technologies:

Technology	Main Function
ePM1 Filter	Fine particulate control
HEPA	High-efficiency particulate control
ULPA	Ultra-high-efficiency particulate control
Molecular Filter	Target-specific AMC control

Reducing pressure drop should not result in inadequate particulate or AMC control.

Energy Efficient Filters for Data Centers

Data centers can require large and continuous cooling-air volumes.

Filter selection should consider:

• Outdoor-air quality.
• Economizer operation.
• Particulate concentration.
• Required airflow.
• Fan energy.
• Filter pressure drop.
• Corrosive gas risk.

Where corrosive gases are a concern, low-resistance particulate filtration alone may be insufficient and appropriate molecular filtration should be evaluated separately.

Energy Efficient Filters for Food Factories

Food facilities may use energy-efficient filtration in:

• Production AHUs.
• Packaging areas.
• High-care areas.
• Ingredient preparation areas.
• Make-up air systems.

The required efficiency should be based on hygiene zoning and process risk rather than energy performance alone.

Energy Efficient Filters for Manufacturing Plants

Manufacturing plants can use low-resistance HVAC filtration for:

• Production areas.
• Control rooms.
• Quality-control rooms.
• Packaging areas.
• Equipment rooms.
• General factory ventilation.

General HVAC filters should not replace dedicated dust collectors, baghouses, cartridge collectors, mist collectors or fume-extraction systems for significant process emissions.

Can a Prefilter Save Energy?

A prefilter adds its own pressure drop, so simply adding another filter does not automatically reduce fan energy.

However, an appropriately selected upstream filter can help protect a more expensive downstream filter from rapid loading.

The complete multi-stage system should therefore be evaluated for:

• Total pressure drop.
• Filter loading.
• Service life.
• Replacement cost.
• Fan energy.

Single-Stage vs Multi-Stage Energy Efficiency

A single-stage system may have lower initial resistance, but it is not automatically the lowest-cost solution over time.

A multi-stage arrangement may protect downstream filters and improve system cleanliness.

The appropriate solution depends on:

• Outdoor-air pollution.
• Target efficiency.
• Operating hours.
• Dust loading.
• Fan capacity.
• Maintenance strategy.

Does Higher Filter Efficiency Always Use More Energy?

Not necessarily.

Higher efficiency often creates additional filtration challenges, but actual resistance depends strongly on:

• Filter media.
• Media area.
• Pleat design.
• Filter depth.
• V-Bank geometry.
• Airflow distribution.

Two filters with the same ISO 16890 efficiency can therefore have substantially different pressure drops and energy performance.

Does Lower Pressure Drop Always Mean Better?

No.

A filter with very low resistance but insufficient filtration efficiency does not meet the required air-quality objective.

The correct comparison is between filters providing technically comparable filtration performance.

Energy Efficient Filters and HEPA

HEPA filtration creates different system requirements from General Ventilation ePM filters.

Where H13 or H14 is required, filter selection should prioritize the required HEPA performance and integrity while also evaluating pressure drop and energy consumption.

An ePM1 low-pressure-drop filter cannot replace an H13/H14 filter when HEPA filtration is required.

Energy Efficient Filters and Activated Carbon

Particulate filter energy efficiency and molecular filtration are separate technical considerations.

ePM1 filters do not provide universal removal of:

• VOCs.
• Odors.
• Acid gases.
• Corrosive gases.

Where gas-phase filtration is required, the pressure drop of the molecular filtration stage should also be included in total system energy analysis.

What Is Total Cost of Ownership?

Total Cost of Ownership (TCO) evaluates the complete cost of operating the filter rather than purchase price alone.

A simplified TCO model can include:

• Filter purchase cost.
• Fan-energy cost.
• Replacement frequency.
• Maintenance labor.
• Disposal cost.
• Downtime.
• Impact on downstream components.

Filter Purchase Price vs Lifecycle Cost

A lower-priced filter is not necessarily the lowest-cost filter over its operating life.

For example, a filter with:

• Higher average pressure drop.
• Shorter service life.
• Lower dust capacity.
• More frequent replacement.

may result in higher overall operating cost even if its initial purchase price is lower.

Air Filter Energy Savings Calculation

A proper energy calculation should consider at least:

• Airflow in m³/s.
• Difference in average pressure drop.
• Fan/system efficiency.
• Annual operating hours.
• Electricity cost.

The resulting savings should be calculated for the actual AHU rather than assuming that a manufacturer's standardized annual energy value equals the exact consumption in the customer's installation.

Example: Comparing Two Filters

Suppose two technically comparable filters provide the same required ISO 16890 efficiency.

Parameter	Filter A	Filter B
Required Efficiency	Same	Same
Average DP	Lower	Higher
Annual Operating Hours	Same	Same
Airflow	Same	Same

All else equal, Filter A would require less fan energy to overcome the filter resistance.

However, service life, purchase cost and replacement frequency should also be considered before deciding which filter provides the lower TCO.

Energy Efficient Air Filter Replacement

When replacing an existing Camfil filter, provide:

• Camfil product name.
• Article number.
• ISO 16890 classification.
• Width × height × depth.
• Rated airflow.
• Initial pressure drop.
• Energy class if available.
• Frame construction.
• Gasket configuration.
• Application.
• Quantity.

Why Dimensions Alone Are Not Enough

Two filters with identical external dimensions can have different:

• ISO 16890 efficiency.
• Initial pressure drop.
• Average operating pressure drop.
• Media area.
• Dust-holding capacity.
• Energy performance.
• Service life.

Therefore, an energy-efficient replacement should not be selected solely by dimensions.

Can Another Brand Replace a Camfil Energy Efficient Filter?

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

Compare:

• ISO 16890 efficiency.
• Dimensions.
• Rated airflow.
• Initial pressure drop.
• Pressure-drop development.
• Energy classification where applicable.
• Dust-holding capacity.
• Service life.
• Frame and gasket.

Comparing only efficiency class and purchase price is insufficient for a meaningful energy-performance comparison.

When Should Energy Efficient Filters Be Replaced?

There is no universal fixed replacement interval.

Replacement should consider:

• Differential pressure.
• Required airflow.
• Manufacturer guidance.
• Operating hours.
• Dust loading.
• Hygiene requirements.
• Physical filter condition.

Replacing a filter too early wastes remaining filter capacity, while replacing it too late can increase resistance and energy consumption.

Differential Pressure Monitoring

Differential-pressure monitoring is particularly useful in energy-conscious HVAC maintenance.

It can help maintenance teams identify:

• Filter loading.
• Increasing resistance.
• Potential airflow problems.
• Appropriate replacement timing.

Where practical, this provides more useful information than replacing filters solely according to a fixed calendar schedule.

Can Energy Efficient Filters Be Washed?

Conventional fine and compact HVAC filters such as these should generally be treated as disposable unless the specific model is explicitly designed for washing.

Washing can damage:

• Fine filter media.
• Pleat geometry.
• Separators.
• Sealants.
• Filter efficiency.

Washing a disposable filter is not a valid energy-saving strategy.
