The FILN05 Series inline disposable filters is a family of final device pneumatic air filters with straight plastic barb fittings for 1/4" OD poly tubing. The FILN05-B inline air filters come with 90° bent fittings. The microfibre disposable filter unit consists of a HEPA Microflex™ filter tube permanently bonded into a sealed nylon casting, ideal for building automation systems, BAS, and HVAC applications. As the HEPA filter shows signs of contamination, simply remove and replace. A replacement model FILN05-R is available without the barb fittings. NOTE: Not for use with synthetic lubricants.
