Description
This high-temperature panel filter provides a stable first-stage filtration solution for such operating conditions. Its synthetic fiber media captures coarse particles while maintaining the airflow required for cooling. The rigid metal frame helps the filter retain its shape during installation and operation.
The filter can be installed in:
- Generator enclosure air intakes
- Power generation box ventilation openings
- Radiator cooling-air sections
- Mobile power station containers
- Industrial heater and dryer ventilation systems
- Multi-stage power equipment filtration modules
For dusty installations, it can be combined with a washable metal mesh pre-filter or a downstream fine filter to create a complete air filtration system.
Technical Parameters
| Grade | Size (mm) | Rated Airflow (m³/h) | Average Arrestance | Initial Pressure Drop (Pa) | Recommended Final Resistance (Pa) | Frame |
|---|---|---|---|---|---|---|
| G3 | 500 × 500 × 15 | 1,000 | 86% | 45 | 180 | Aluminum Alloy / Galvanized Steel |
| G4 | 500 × 500 × 25 | 1,200 | 90% | 50 | 200 | Aluminum Alloy / Galvanized Steel |
| G4 | 500 × 500 × 46 | 1,200 | 90% | 50 | 200 | Aluminum Alloy / Galvanized Steel |
The values above are nominal specifications. Actual airflow resistance and service life may vary according to operating temperature, airflow velocity, dust concentration, installation sealing and maintenance conditions.

Applications
| Generator Enclosure Air Intakes | Radiator and Cooling Sections | Power Equipment Containers | Industrial Thermal Equipment |
|---|---|---|---|
| Used as a primary filter in diesel and gas generator boxes to reduce dust entry while maintaining the cooling airflow required by the genset. | Installed upstream of radiators, cooling fans and heat exchangers to limit contamination and support stable heat dissipation. | Suitable for mobile power stations, electrical containers, UPS modules and auxiliary power cabinets exposed to elevated internal temperatures. | Applied in spray dryers, industrial drying equipment and other ventilation systems requiring heat-resistant coarse filtration. |
Benefits for Power Generation Boxes
| Heat-Resistant Operation | Cooling Airflow Protection | Equipment Cleanliness | Flexible System Integration |
|---|---|---|---|
| Synthetic fiber media and rigid framing support stable operation in warmer ventilation sections. | Controlled pressure drop helps preserve the airflow needed to cool engines, alternators and radiators. | Coarse contaminants are captured before reaching heat-transfer surfaces and electrical components. | Multiple grades, depths and frame options allow the filter to be integrated into different generator enclosure designs. |
