Wilkerson D28-04-FKG0B Frl Unit 110 Scfm 150 Psi 1/2 Npt

Product Description

The WILKERSON D28-04-FKG0B is a 2-piece filter/regulator-lubricator (FRL) combination unit designed to condition compressed air at the point of use. It filters particulates down to 5 microns, regulates downstream pressure, and lubricates pneumatic tools or actuators in a single inline assembly. Rated for 110 SCFM flow and a maximum supply pressure of 150 psi, it connects via 1/2 inch NPT ports and fits into standard compressed air distribution lines. The aluminum body and polycarbonate bowl with bowl guard make it suitable for industrial service environments. A pressure gauge is included for direct inline monitoring.

This FRL unit is used in industrial, commercial, and light manufacturing environments where compressed air tools, pneumatic cylinders, or air-driven equipment require clean, regulated, and lubricated air supply. The 1/2 inch NPT port size suits medium-flow branch lines. Brackets are included for panel or wall mounting. It is typically installed by maintenance technicians, pipefitters, or pneumatic system technicians during new equipment commissioning or as a direct replacement on existing compressed air drops.

Key Features

• 110 SCFM flow capacity with 150 psi maximum supply pressure
• 5-micron filter element removes particulates from the compressed air stream
• Integrated lubricator with 6.00 oz bowl capacity for downstream component lubrication
• Filter bowl capacity of 2.9 oz with manual drain for condensate removal
• Pressure gauge and 1/4 inch gauge port included for downstream pressure monitoring
• Modular connection design allows expansion or reconfiguration of the air preparation assembly
• Mounting brackets included for direct panel or wall installation

Compatibility

Designed as an OEM-style replacement or new-installation FRL unit for compressed air systems requiring 1/2 inch NPT connections in the Wilkerson Series 28 modular air preparation lineup.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air supply before removing any existing FRL components or making new connections. Apply thread sealant appropriate for pneumatic service to all NPT fittings and verify all connections for leaks before returning the system to full operating pressure. Observe the rated temperature range of -13 degrees F to 125 degrees F when selecting the installation location.
