Product Features
The F6 High Temp Mini Pleat Filter provides distinct advantages through specialized engineering. The following features demonstrate its value.
1. 250°C Endurance without Media Failure
Operates continuously at 250°C with no media breakdown. This High Temperature Fiberglass Filter ensures reliable particle capture throughout its service life, protecting downstream equipment and maintaining air quality in high-heat environments .
2. Lightweight Aluminium Frame Reduces Load
Corrosion-resistant aluminum frame lowers installation weight significantly.
3. Dual Mesh Guards Prevent Handling Damage
Double-sided steel mesh protects pleats during transport.
4. Mini Pleats Boost Media Area in Compact Depth
Maximizes dust holding capacity within shallow housings. This F6 Class Aluminum Frame Filter delivers high airflow capacity with low initial pressure drop, translating to reduced fan energy consumption and lower operating costs .
5. Chemical Stability Suits Corrosive Hot Air Streams
Resists acid and alkali fumes in process exhaust.
6. Low Initial Pressure Drop Saves Fan Energy
Starts at ≤250 Pa at rated airflow volume.

Product Applications
The F6 High Temp Mini Pleat Filter is specifically designed for high-temperature industrial air handling applications requiring reliable particle capture. As a 250℃ Industrial Air Filter, it excels in scenarios where standard filters cannot survive.
1. Paint Curing Ovens – Captures overspray particulates at 230°C without emissions.
2. Textile Dryer Intakes – Removes lint from 220°C recirculated drying air.
3. Food Processing Hot Air Units – Filters cooking oil fumes and starch dust safely.
4. Pharmaceutical Fluid Bed Dryers – Prevents product cross-contamination during granulation.
5. Ceramic Kiln Exhaust Systems – Protects fans from abrasive dust at 250°C.
6. Heat Recovery Ventilation Units – Maintains clean heat exchanger surfaces efficiently.
