Product Description

Product Description

The High Temp Resistant Mini Pleat Air Filter is specifically engineered for industrial applications requiring reliable filtration under extreme thermal conditions. Operating continuously at 250℃ and withstanding peak temperatures up to 300℃, this filter solves a critical challenge in high-temperature ventilation systems: maintaining filtration efficiency without media degradation. 
Whether installed in paint spray booths, drying ovens, or industrial exhaust systems, buyers can expect consistent particle capture, reduced maintenance frequency, and protection of downstream sensitive equipment. The F6 Class Air Filter designation confirms its ability to capture 0.4μm particles at 65% efficiency, making it an ideal middle-stage filtration solution for demanding thermal environments.

Product Features

The High Temp Resistant Mini Pleat Air Filter delivers exceptional performance through its specialized design and material selection. Below are the key features that distinguish this product from conventional air filters. 1. Superior High-Temperature Endurance – The fiberglass media maintains its pleated structure at 250℃ continuous operation and 300℃ peak exposure. 2. F6 Class Filtration Efficiency – As a certified F6 Class Air Filter, it achieves 65% efficiency at 0.4μm particle size. This performance level effectively captures fine process dust, welding fumes, and atmospheric particulates, protecting downstream HEPA filters or sensitive equipment from premature loading. 3. Robust Galvanized Frame with Gasket – The galvanized steel frame resists corrosion and deformation under thermal cycling. A pre-installed gasket on the air outlet side ensures leak-free installation, preventing unfiltered air bypass. Double-sided metal mesh face guards protect the delicate fiberglass pleats during handling and operation. 4. Low Initial Resistance – With an initial pressure drop of ≤250 Pa at 2200 CMH airflow, this 250℃ Industrial Air Filter minimizes energy consumption by fans. Lower resistance translates directly to reduced operational costs over the filter's service life.

Product Applications

The High Temp Resistant Mini Pleat Air Filter is specifically designed for high-temperature industrial air handling systems. Below are the primary application scenarios.

--Automotive Paint Spray Booths – Recirculated air in paint drying ovens reaches 200-250℃. This filter captures overspray particles while withstanding the heat, maintaining clean airflow and preventing surface defects on painted vehicle bodies.

--Industrial Drying Ovens – In textile, printing, and food processing industries, drying ovens require filtration of recirculated hot air to remove lint and particulates. The fiberglass media does not release fibers or degrade under sustained high temperatures.

--Pharmaceutical and Chemical Processing – Many drying and granulation processes operate at elevated temperatures. This High Temperature Fiberglass Filter prevents cross-contamination and protects final product purity by capturing airborne particles before they settle on processed materials.

--HVAC Systems with High-Temperature Ductwork – Industrial facilities with heat recovery systems or kiln exhaust often have duct temperatures exceeding standard filter ratings. This product bridges that gap, enabling effective filtration where standard filters would fail.
