Wilkerson D28-04-FLG0B Frl Unit 110 Scfm 1/2 Npt

Product Description

The WILKERSON D28-04-FLG0B is a 2-piece filter/regulator/lubricator (FRL) combination unit designed to condition compressed air in pneumatic systems. It filters particulates down to 5 microns, regulates supply pressure, and delivers lubricated air to downstream equipment in a single modular assembly. Rated for 110 SCFM flow and a maximum supply pressure of 250 psi, this unit connects via 1/2 inch NPT ports and ships with a pressure gauge included. The aluminum body and bowl construction keep weight low while offering solid resistance to corrosion from condensate. A licensed pneumatic technician or industrial maintenance tech is the typical installer.

This FRL unit suits industrial and commercial pneumatic applications where consistent air quality and lubrication are required at the tool or actuator. The 2-piece configuration combines filtration and regulation in one module with lubrication in the second, allowing for compact inline installation. The modular connection design supports future expansion or component swap-out without full disassembly. With a manual drain, a built-in sight glass, and brackets included, this unit is ready for panel or manifold mounting in shop air, automation, or production-line environments operating between -13 degrees F and 150 degrees F.

Key Features

• 110 SCFM flow rate with 250 psi maximum supply pressure
• 5-micron filtration rating removes fine particulates from compressed air
• 1/2 inch NPT end connections with 1/4 inch gauge port
• Aluminum bowl and body construction — lightweight and corrosion-resistant
• Includes pressure gauge, sight glass, and mounting brackets
• Modular connection supports inline expansion or component replacement
• Manual drain for controlled condensate removal

Compatibility

Designed as an OEM-style replacement or new-installation FRL unit for compressed air systems requiring 1/2 inch NPT connections and Series 28 modular component compatibility.

Installation Notes

Installation is typically performed by a qualified pneumatic or industrial maintenance technician. Depressurize and lock out the compressed air supply completely before installing or servicing this unit. Mount with flow direction arrow aligned to system airflow; brackets are included for rigid panel or rail mounting. Consult applicable facility safety codes and equipment manufacturer guidelines for torque and sealing requirements on NPT threaded connections.
