The multi-pocket design provides a larger media surface area within a limited installation space, promoting more uniform airflow distribution. Compared with standard primary panel filters, it is better suited for high-airflow air handling units, AHUs and centralized ventilation systems.
Deep filter pockets can retain more dust, fibers and other coarse airborne particles. This slows the increase in operating resistance, extends replacement intervals and reduces equipment downtime and routine maintenance costs.
The optimized filter media, pocket spacing and airflow passages help control pressure drop and reduce the energy required by the fan to overcome system resistance. When operated at the rated airflow, the filter provides a practical balance between filtration performance and energy efficiency.
A G4 bag filter serves as the prefiltration stage of an air handling system. It effectively captures coarse contaminants, reduces the dust load on medium- and high-efficiency filters, delays downstream filter clogging and helps maintain stable system airflow.
Stable synthetic-fiber media and securely constructed filter pockets help reduce seam separation, media damage and pocket contact during operation. The filter is suitable for ventilation systems requiring continuous, long-term operation.
Dimensions, number of pockets, pocket depth, filtration grade, frame material and filter media can be customized according to project requirements. The product is suitable for new equipment, existing-system upgrades and OEM/ODM procurement.

Widely used as a prefilter in air handling units, modular AHUs, central air-conditioning systems and fresh-air systems. It captures dust, fibers and other coarse particles, reduces contamination of coils, fans and ductwork, and helps maintain airflow and operating efficiency.
Suitable for the prefiltration stage of pharmaceutical plants, GMP production areas and cleanroom air handling systems. It reduces the dust load on downstream medium- and high-efficiency filters. The complete filtration configuration should be determined according to the required cleanliness class, production process and project specifications.
Applicable to general hospital ventilation systems, outpatient departments, offices, auxiliary rooms and other non-critical areas. It protects downstream filtration equipment. Operating rooms, sterile zones and other critical environments require additional medium- and high-efficiency filtration stages.
Used as a prefilter in air handling units serving electronics manufacturing workshops, precision assembly areas and cleanrooms. It reduces the entry of coarse particles, protects downstream precision filters and helps extend their service life.
Suitable for ventilation and air-conditioning systems in food-processing areas, beverage plants, packaging zones and auxiliary workshops. It reduces airborne dust and fibers, helps improve the production environment and protects air handling equipment.
Suitable for central air-conditioning and fresh-air systems in offices, shopping centers, hotels, airports, schools and public venues. Its broad airflow range, convenient maintenance and relatively low operating cost make it suitable for routine air prefiltration.
Compared with a primary panel filter, the bag-type construction provides greater dust-holding capacity and generally supports a longer operating cycle.
Particularly suitable for air handling units, central air-conditioning systems and other applications requiring large airflow volumes.
The properly designed pocket structure helps distribute airflow evenly and control system pressure drop.
Consistently captures coarse airborne contaminants and protects downstream filtration stages.
Multiple specifications and project-specific configurations are available.
G3 and G4 primary filtration grades are available. For projects specified according to ISO 16890, the corresponding ISO Coarse classification should be confirmed using the actual test report rather than through a simple direct conversion.
Available with 3, 4, 5, 6 or 8 pockets. Pocket depth can also be customized according to rated airflow and available installation space. Selecting the appropriate number and depth of pockets helps improve dust-holding capacity and airflow distribution.
Available with galvanized-steel, aluminum-alloy or stainless-steel frames. Galvanized steel is suitable for general HVAC projects; aluminum alloy offers lower weight; stainless steel is recommended for applications requiring better corrosion resistance or higher hygiene standards.
Synthetic-fiber, nonwoven and flame-retardant filter media are available. For high-humidity, special-temperature or fire-rated applications, detailed operating conditions should be provided during the inquiry stage.
Non-standard dimensions, special pocket depths, customized packaging, labels and OEM/ODM branding are available. When requesting a quotation, please provide the filter dimensions, rated airflow, filtration grade, initial-resistance requirement, frame material and required quantity.
