Koch Filter's Multi-Cell CS filters are rigid, extended surface panel filters designed to provide high efficiency filtration in a compact, space-saving 2" or 4" deep frame.

They are constructed with microfiberglass air filter media engineered specifically for high efficiency applications. The pleated media is supported by precision-crafted corrugated aluminum separators, ensuring proper airflow. The entire media pack is sealed within a rugged yet lightweight aluminized steel frame.

Multi-Cell CS filters are suitable for a wide variety of air filtration applications and are especially effective for upgrading existing systems where space constraints limit expansion or modifications. Their compact 2" or 4" depth allows easy replacement of standard pleated or low-efficiency filters without requiring changes to existing housings.

These filters are UL Class 1 rated and can operate in high-temperature environments up to 750°F, making them ideal for demanding applications such as automotive paint booths and industrial coating operations.
