High-temperature resistant high-efficiency filters are air purification devices specifically designed for high-temperature environments

High-Temperature High-Efficiency Filter Product Structure and Materials

1. Outer Frame Material

Primarily made of stainless steel (304/316L) or galvanized steel sheet;  some models use aluminum profiles.

Stainless steel frames offer excellent oxidation resistance and structural strength, suitable for frequent temperature fluctuations.

Common frame thicknesses: 80mm, 150mm, 220mm, 292mm, etc.

2. High-Temperature High-Efficiency Filter Media Material

The core filter media is ultra-fine glass fiber filter paper, featuring high temperature resistance, chemical corrosion resistance, and high filtration efficiency.

Some models use glass fiber filter paper with waterproof adhesive.

3. High-Temperature High-Efficiency Filter Separator Structure

Separator Design: Uses aluminum foil or stainless steel foil as corrugated separators to precisely maintain the spacing between filter paper pleats, maximizing filter media utilization with minimal resistance.

Separator-Free Design (Some Models): Employs a continuous strip-shaped filter media self-supporting structure, forming a rigid whole and reducing the risk of metal particle shedding.

Sealant: High-temperature resistant silicone, ceramic-based sealant, or imported flexible sealing materials.

Gaskets: Fiberglass gaskets, special rubber, or seamless one-piece molded polyurethane gaskets.

Models utilize flexible sealing technology (such as HT Proseal Tech), effectively absorbing stress from thermal expansion and contraction, preventing seal cracking and leakage.
