- Slash Maintenance Costs: Stop frequent filter replacements; our high-capacity pockets hold 30% more dust, extending the service life of your expensive downstream HEPA filters.
- Leak-Proof Welding: Eliminate air bypass issues with our ultra welded pocket edges that provide a reinforced, airtight seal, even under high-velocity airflow.
- 25% Energy Savings: Featuring an ultra-low initial resistance of only 45Pa (F7 grade), our filters reduce fan power consumption by an average of 25% compared to industry-standard bags.
- 99% Efficiency on 1-Micron Particles: Independently tested to capture over 99% of fine dust and allergens, providing superior protection for pharmaceutical and hospital HVAC systems.
- Pre-Filtration for Cleanrooms: The perfect first line of defense for ISO-standard cleanrooms, protecting high-cost terminal filters and maintaining strict air quality requirements.
- High-Humidity HVAC Environments: Engineered with moisture-resistant synthetic media that maintains structural integrity and filtration efficiency even in 100% relative humidity.
- Superior Dust Holding Capacity: Offers 2x the dust collection volume of traditional glass fiber bags, reducing labor costs and system downtime for filter change-outs.
- Rigid Internal Support Frames: Unlike flimsy competitors, our pockets feature internal aerodynamic spacers that prevent pocket collapse and ensure uniform air distribution across the entire surface.

FAQ
- What filtration grades do you offer for bag filters?
- We provide a full range of filtration grades from ISO Coarse (G4) to ePM1 (F9), complying with EN779 and ISO 16890 standards. F7 and F8 are our most popular grades for commercial and industrial HVAC systems.
- What is the difference between Synthetic Media and Glass Fiber Media?
- Synthetic media is durable, moisture-resistant, and non-shedding, making it ideal for food and pharma industries. Glass fiber offers higher temperature resistance and stable efficiency but can be brittle. We recommend synthetic pockets for most general ventilation needs due to their lower energy consumption.
- How do you ensure the pockets don't collapse or touch each other during operation?
- Our bag filters feature internal aerodynamic spacers and stitched channels. This ensures each pocket remains fully inflated and separated, allowing for uniform airflow and utilization of the entire filtration surface.
- What is the initial resistance of an F7 bag filter?
- At a standard airflow of 3400 m3/h, the initial resistance of our high-efficiency F7 bag filter is typically between 45Pa and 65Pa, depending on the number of pockets and bag depth. Low resistance helps reduce your system's energy costs.
- Can you customize the sizes and number of pockets?
- Yes, we are a professional manufacturer. We can customize the frame dimensions (width/height), bag depth, and the number of pockets (e.g., 3, 6, 8, or 10 pockets) to meet your specific HVAC unit requirements.
- What frame materials are available?
- We offer frames in Galvanized Steel (GI), Extruded Aluminum, and Heavy-duty Plastic (ABS). Plastic frames are fully incinerable and ideal for facilities with strict waste disposal regulations.
- When should I replace the bag filter?
- We recommend replacing the filter when the pressure drop reaches 2 to 3 times the initial resistance, or generally between 250Pa and 450Pa. Regular replacement prevents system strain and maintains air purity.
- Are your filters moisture resistant?
- Yes, our synthetic bag filters are highly resistant to humidity and can operate effectively in environments with up to 100% relative humidity. They do not promote microbial growth, ensuring a hygienic air supply.
- How are the filters packaged to save on international shipping?
- Bag filters are naturally collapsible. We use space-saving flat-pack methods or nest them in heavy-duty cartons. This significantly reduces the shipping volume and lowers the landed cost for our international clients.
- Do you provide test reports with the shipment?
- Yes, every batch undergoes strict QC. We can provide factory test reports covering filtration efficiency and pressure drop. We also have certifications like ISO 9001 to ensure consistent quality.
