The WILKERSON F28-04-SL00B is a general purpose compressed air filter designed to remove contaminants from compressed air lines in industrial and commercial pneumatic systems. Built on the Wilkerson Series 28 modular platform, it accepts a 1/2 inch NPT port connection and delivers a flow capacity of 120 standard cubic feet per minute (SCFM). The filter uses a sintered polyethylene filter media element to capture particulates and moisture aerosols before they reach downstream equipment. An aluminum bowl with a nylon bowl guard protects the internal components, and a built-in sight glass allows technicians to monitor fluid accumulation without disassembly. A manual drain provides straightforward bowl drainage during service.
This filter is suited for use in light manufacturing, maintenance shops, and process environments where clean, dry air is required at the point of use. It installs inline on 1/2 inch NPT compressed air distribution lines supplying pneumatic tools, actuators, valves, and instrumentation. The Series 28 modular connection design allows it to be combined with Wilkerson Series 28 regulators and lubricators to build a filter-regulator-lubricator (FRL) assembly at a single station.
Designed as an OEM-style replacement and service filter for Wilkerson Series 28 compressed air filter assemblies using 1/2 inch NPT end connections.
Installation is performed by a qualified industrial maintenance technician or pipefitter working on compressed air distribution systems. Depressurize and lock out the compressed air supply line before removing the existing filter or installing this unit. Use thread sealant appropriate for compressed air service on all NPT connections and torque fittings per standard pipe fitting practices. Verify flow direction and confirm the bowl drain is accessible for routine service after installation.
