High-Temperature Deep-Pleat HEPA Filters: Advanced Air Purification for Extreme Conditions

In modern industrial, laboratory, and cleanroom environments, air quality, safety, and reliability are paramount. The High-Temperature Deep-Pleat HEPA Filter is engineered to meet these rigorous demands, providing high-efficiency filtration even under extreme thermal conditions. Designed with advanced media and robust construction, this filter ensures consistent performance, long service life, and superior protection for sensitive equipment, products, and personnel.

Main Framework & Structure

High-Temperature Deep-Pleat HEPA Filters feature densely packed pleated filtration media made from heat-resistant fibers. The deep-pleat design maximizes surface area, enhancing dust-holding capacity and extending service life. Frames are constructed from high-grade steel or aluminum, ensuring structural integrity under high-temperature operation. The filter is designed to withstand continuous airflow in demanding applications, maintaining efficiency without deformation or collapse. Optional gasketing and sealing systems provide airtight installation, preventing bypass and ensuring maximum filtration efficiency.

This filter can be customized according to customer requirements to withstand continuous operating temperatures of 250–300°C, with an instantaneous resistance of up to 320°C. The filtration media consists of high-temperature resistant fiberglass filter paper and aluminum foil corrugated separators, while the sealant glue is designed to endure continuous high temperatures up to 300°C, withstanding peaks of 320°C.
