Camfil HVAC Filters Vietnam – Air Filtration Solutions for AHU, FAHU and Ventilation Systems

Camfil HVAC Filters Vietnam covers air filtration solutions for commercial buildings, industrial facilities, manufacturing plants and central heating, ventilation and air-conditioning systems.

VIETPHAT supports customers in Vietnam with Camfil HVAC filter selection, product identification, technical specification matching, replacement filter sourcing and quotation requests.

The product range includes panel prefilters, bag filters, compact filters and selected molecular filtration solutions for applications requiring both particulate and gaseous contaminant control.

Correct HVAC filter selection requires more than choosing a filtration efficiency class. Engineers must also evaluate airflow, pressure drop, dimensions, filter construction, installation compatibility, operating conditions and maintenance requirements.

1. What Are Camfil HVAC Filters?

HVAC air filters are installed in ventilation and air-conditioning systems to remove airborne particles from outdoor air, recirculated air or a combination of both.

Camfil manufactures general ventilation filters in multiple constructions and efficiency classes for commercial and industrial applications.

Typical HVAC filter categories include:

Panel Filters.
Bag or Pocket Filters.
Compact Filters.
V-Bank Filters.
Combined particulate and molecular filters.
Specialized filters for selected applications.

Each category serves different installation, airflow and filtration requirements.

2. Camfil HVAC Filter Product Range

Filter Category	Camfil Product Examples	Primary Function	Typical Application
Panel Prefilter	30/30 and selected panel products	First-stage particulate filtration	AHU, FAHU, HVAC

Exact product availability, performance and compatibility must be verified using the manufacturer's current documentation.

3. Camfil Panel Filters for HVAC Prefiltration

Panel filters are commonly installed as the first filtration stage in an HVAC air-handling unit.

Their primary function is to capture a portion of the incoming particulate load before air passes through downstream fine filters or other filtration stages.

Benefits of HVAC Prefiltration

Reduces dust loading on downstream filters.
Helps protect cooling and heating coils.
Reduces particulate accumulation within selected HVAC components.
Supports multistage filtration design.
May help extend downstream filter service life.

Camfil 30/30 is an example of a panel filter family that may be considered for suitable general ventilation applications.

Efficiency, dimensions and pressure drop vary according to the exact model.

4. Camfil Hi-Flo HVAC Bag Filters

Camfil Hi-Flo is a range of pocket filters designed for commercial and industrial ventilation.

Its multi-pocket construction provides a large filtration surface, while optimized pocket geometry helps manage airflow resistance.

Technical Features

Multiple ISO 16890 efficiency configurations.
Large filtration media area.
Optimized pocket design.
Different frame sizes and pocket depths.
Configurations designed for energy-efficient operation.
Options suitable for various commercial and industrial AHUs.

Typical Applications

Office building HVAC systems.
Shopping centers.
Hotels.
Manufacturing plant ventilation.
Industrial air handling units.
Selected cleanroom prefiltration systems.

When ordering a replacement Hi-Flo filter, customers should provide the exact product code, dimensions, number of pockets, efficiency classification and rated airflow.

5. Camfil Opakfil Compact HVAC Filters

Camfil Opakfil is a compact filter family designed for general ventilation applications.

Its V-shaped construction provides a relatively large filtration area within a compact installation depth.

Selected Opakfil configurations offer high particulate efficiency according to ISO 16890, making them suitable for a range of AHU applications.

When to Consider Opakfil

AHUs with limited installation depth.
Systems requiring compact fine filtration.
Projects evaluating pressure drop and energy consumption.
Existing compact-filter replacement.
Selected cleanroom prefiltration applications.

Compact filters should not automatically replace bag filters simply because their front dimensions are similar. Holding-frame compatibility, depth, airflow and pressure drop must be checked.

6. Camfil City-Flo HVAC Filters

Commercial buildings located in urban environments may need to control both airborne particles and selected gaseous pollutants.

Camfil City-Flo combines particulate and molecular filtration within a single filter stage.

This type of filter can be considered for HVAC applications with suitable low-concentration gaseous contaminant loads.

Potential Applications

Office buildings near busy roads.
Hotels in urban areas.
Shopping centers.
Commercial buildings with specific indoor air quality requirements.
Selected fresh-air handling systems.

The ability to remove a particular gas depends on the filter media, contaminant concentration, airflow, humidity and operating conditions.

City-Flo must not be assumed to remove all gases, odors or volatile organic compounds.

7. Camfil HVAC Filter Efficiency – ISO 16890

ISO 16890 is a particulate air filter classification system used for general ventilation.

Classification	Meaning	Typical Selection Consideration
ISO Coarse	Coarse particulate filtration	First-stage filtration
ePM10	Efficiency classification related to PM10	General ventilation
ePM2.5	Efficiency classification related to PM2.5	Fine particulate control
ePM1	Efficiency classification related to PM1	Fine particulate control

Selection should be based on the required indoor air quality, outdoor pollution conditions and the HVAC system's design.

Historical EN 779 classes such as G4, M5, F7, F8 and F9 do not have a universally exact one-to-one conversion to ISO 16890.

8. Camfil HVAC Filters for AHU Systems

Air handling units are used in many commercial and industrial facilities to condition, filter and distribute air.

A typical multistage particulate filtration arrangement may include:

Panel Prefilter → Bag or Compact Fine Filter → Supply Air.

Applications requiring additional high-efficiency filtration may use a separate HEPA stage, subject to the system design.

The final arrangement depends on the required air quality, equipment configuration, airflow and available fan static pressure.

9. Camfil HVAC Filters for FAHU and Fresh-Air Systems

Fresh-air handling units process outdoor air before supplying it to occupied or controlled spaces.

Because outdoor air quality varies by location, the filtration strategy should account for local particulate pollution and any relevant gaseous contaminants.

Possible configurations include:

Panel prefilter and fine filter.
Panel prefilter and compact filter.
Particulate filtration combined with selected molecular filtration.

The required configuration must be established through the project's ventilation and air quality specifications.

10. Camfil HVAC Filters for FCU Systems

Fan coil units often have limited installation space and lower available static pressure than central AHUs.

For this reason, filter replacement must consider:

Available installation dimensions.
Filter thickness.
Rated airflow.
Initial pressure drop.
Fan performance.
Maintenance access.

High-efficiency compact or HEPA filters should not be installed in an FCU unless the equipment is designed or properly evaluated for the additional airflow resistance.

11. Camfil HVAC Filters for Commercial Buildings

Office towers, shopping centers, hotels and mixed-use buildings typically operate HVAC systems for extended periods.

Filtration design should consider indoor air quality, operating hours, maintenance access, filter replacement costs and fan energy consumption.

Selected Camfil bag and compact filters can be evaluated for these applications.

For buildings affected by low concentrations of urban gaseous pollutants, combined particulate and molecular filtration may also be appropriate.

12. Camfil HVAC Filters for Manufacturing Plants

Manufacturing facilities may require different filtration levels across production areas, offices, packaging rooms and utility spaces.

General ventilation systems commonly use prefilters and fine filters.

More demanding production environments may require additional HEPA filtration or specialized molecular filtration.

Standard HVAC filters must not be treated as substitutes for process-specific dust collection, welding-fume extraction, paint-mist capture or industrial exhaust-gas treatment.

13. Camfil HVAC Filters for Pharmaceutical Facilities

Pharmaceutical manufacturing facilities often use multistage filtration to support contamination-control strategies.

Camfil general ventilation filters may serve as prefiltration stages for selected high-efficiency filtration systems.

Where HEPA filtration is required, filter selection and installation must follow the applicable project specifications and qualification procedures.

The use of a particular filter class alone does not establish GMP compliance.

14. Camfil HVAC Filters for Food Manufacturing

Food-processing facilities can have different filtration requirements depending on hygiene zoning, process conditions and product exposure.

Panel, bag, compact and selected high-efficiency filters may be considered according to the ventilation design.

There is no universal requirement for every food-production area to use HEPA or ULPA filtration.

15. Camfil HVAC Filters for Electronics Facilities

Electronics manufacturing facilities may require both general ventilation filtration and more stringent particulate control in selected production areas.

Where airborne molecular contamination is relevant, molecular filtration must be assessed separately.

Filter selection should consider the process requirements, material compatibility and contamination-control strategy.

16. Camfil Energy-Efficient HVAC Filtration

Air filters contribute to the overall pressure resistance of an HVAC system.

For systems designed to maintain a constant airflow rate, higher filter pressure drop can increase fan energy requirements.

Therefore, filter selection should consider both filtration efficiency and operating pressure drop.

Important Life-Cycle Cost Factors

Initial filter price.
Filtration efficiency.
Initial pressure drop.
Average operating pressure drop.
Rated airflow.
Operating hours.
Expected service life.
Maintenance labor.
Replacement and disposal costs.

Energy-saving claims should be evaluated using the actual HVAC system's operating conditions.

17. How to Select Camfil HVAC Filters

Step 1: Identify the HVAC Equipment

Determine whether the filter is required for an AHU, FAHU, FCU or another ventilation system.

Step 2: Define the Filtration Objective

Identify the required particulate efficiency and any relevant gaseous contaminant-control requirements.

Step 3: Confirm Dimensions

Measure the existing filter's width, height and depth, or use the equipment's approved filter specification.

Step 4: Check Rated Airflow

Determine the design airflow through each filter module.

Step 5: Evaluate Pressure Drop

Check the filter's initial and expected operating pressure drop against the available fan static pressure.

Step 6: Verify Installation Compatibility

Confirm the holding frame, header, gasket and available installation depth.

Step 7: Review Technical Documentation

Use the exact product datasheet and applicable performance documentation.
