Sterile filters NES

Gardner Denver industrial Sterile filters are filters for aseptic processes designed with an engineering-first approach: to deliver integrated sterile filtration with consistent performance and defensible TCO.

Sterile compressed air filtration with borosilicate glass microfiber

The borosilicate glass microfiber filters retain particles, bacteria and aerosols down to 0.01 micron, with DOP penetration < 0.0001%, guaranteeing aseptic compressed air for critical, regulated processes.

NES series for critical applications

NES Series: AISI 316L stainless steel housing, SIP (in-situ steam) sterilization — designed for continuous, high-throughput aseptic lines.

Native integration with compressed air systems

Compatible with existing compressed air infrastructure and CIP/SIP loops, the filters enable integrated sterile filtration without added installation or maintenance complexity.
