G2 Grade Primary Fiberglass Panel Filter | HVAC Pre-filtration with Custom Frame Sizes
This high-performance Primary Fiberglass Panel Filter is engineered for the efficient capture of atmospheric dust particles above 10μm. With a certified G2 filtration class, it offers an exceptional low pressure drop of just 25Pa, ensuring maximum energy efficiency for industrial air handling units. Constructed with corrosion-resistant green and white fiberglass media , this filter is available in versatile 21mm, 25mm, and 46mm thicknesses to fit any standard or custom system.
Product Key Features
- Energy Efficient: Features low resistance (25Pa) and a large filter area to reduce energy consumption in ventilation systems.
- High Flow Capacity: Specifically designed to support high air flow requirements up to 6000 m³/h.
- Standard Thickness: Available in 21mm, 25mm, and 46mm to fit most standard HVAC housings.
- Durable Performance: Offers a long service life, reducing the frequency of maintenance and replacement.
Material & Craftsmanship
- Media: High-loft, primary filtration fiberglass cotton (Green/White).
- Frame: Robust Aluminum Alloy, Galvanized Iron, or Reinforced Paper frames.
- Support: Double-sided protective mesh (Painted or Aluminum) for high-velocity stability.
Applications
- Commercial HVAC Systems: The essential primary air filter for shopping malls, office towers, and hospitals to extend the life of expensive secondary HEPA filters.
- Automotive & Industrial Spray Booths: Specialized paint arrestor filter to capture overspray and protect exhaust fans from resin buildup.
- Silk-Screen Printing Workshops: Effectively filters corrosive gas and ink particulates, maintaining a clean breathing environment.
- Food & Pharmaceutical Pre-filtration: Used in intake air units to remove large particles before air enters cleanroom stages.
- General Manufacturing: Provides high-volume air exchange for furniture factories, metalworking shops, and warehouses.
- Data Centers: Reliable pre-filtration to prevent dust accumulation on sensitive electronic components.

Frequently Asked Questions
Q1: What is the difference between green/white fiberglass and standard air filters?
The green/white fiberglass media is specifically designed with a progressive density structure. The green side (air entering) is more open to trap larger particles, while the white side (air exiting) is denser to ensure high dust holding capacity and prevent blow-through.
Q2: Can these filters be customized for non-standard HVAC housings?
Yes. As a direct factory-wholesale supplier, we specialize in custom size fiberglass air filters. We can adjust the frame material (Aluminum/Galvanized) and the specific dimensions to meet your industrial air handling requirements.
Q3: How often should I replace my primary fiberglass panel filter?
While it depends on your environment, our filters are built for a long service life. Typically, for HVAC pre-filtration, we recommend replacement when the pressure drop exceeds 150Pa to maintain energy efficiency.
Q4: Is the media resistant to chemicals?
Absolutely. Our fiberglass media is acid and alkali resistant, making it the ideal corrosion-resistant filter for the silk-screen printing and chemical coating industries.
Q5: Do you offer bulk pricing for distributors?
Yes, Chuqi provides competitive wholesale fiberglass air filter pricing for global distributors and large-scale industrial projects.
