GCW Heat-Resistant Semi-HEPA Filter (500°C)
Product Overview
GCW is a heat-resistant Semi-HEPA filter rated for continuous 500°C service, with 90% efficiency @ 0.5-1.0 μm. Its glass-fiber media reinforced with stainless-steel mesh makes it an ideal pre-filter for ATMWC-class HEPAs, or a standalone filter for high-temperature applications where sub-HEPA performance is adequate.
Key features
・Continuous operation up to 500°C
・90% @ 0.5-1.0 μm (Semi-HEPA class)
・High-strength build (glass fiber + stainless-steel mesh)
・Ideal ATMWC pre-filter to extend main-filter life
Target industries:Medical, Pharmaceutical, Electronics, Power generation, Nuclear power
