Wilkerson C28-04-FLG0B Frl Unit 90 Scfm 1/2 Npt

Product Description

The WILKERSON C28-04-FLG0B is a 3-piece filter-regulator-lubricator (FRL) combination unit designed to condition compressed air at the point of use in pneumatic systems. It filters particulate down to 5 microns, regulates supply pressure up to 250 psi, and delivers lubricated air to downstream tooling and actuators in a single modular assembly. Rated at 90 SCFM, it handles the flow demands of most industrial pneumatic circuits. The unit connects via 1/2 inch NPT ports and ships with a pressure gauge, sight glass, and mounting brackets included. Aluminum construction keeps weight manageable while offering good corrosion resistance for typical shop-air environments.

This FRL unit is suited for industrial and commercial pneumatic installations where consistent air quality and pressure regulation are required ahead of tools, cylinders, valves, and other air-operated equipment. The modular Series 28 body design allows components to be serviced or reconfigured independently. The manual drain on the filter bowl and the 6.00-ounce lubricator bowl capacity make it practical for production environments where periodic maintenance is performed by maintenance technicians or pipefitters. Operating temperature range spans -13 degrees F to 150 degrees F, covering most indoor and enclosed industrial settings.

Key Features

• 3-piece FRL configuration: filter, regulator, and lubricator in one modular assembly
• 90 SCFM flow rating at 1/2 inch NPT port size
• 250 psi maximum supply pressure with integrated pressure gauge included
• 5-micron filtration with aluminum bowl, manual drain, and 2.9-ounce filter bowl capacity
• 6.00-ounce lubricator bowl capacity with sight glass for fluid level monitoring
• Mounting brackets included; modular connection supports inline expansion

Compatibility

Designed as an OEM-style replacement or new-installation FRL unit for industrial compressed-air systems requiring 1/2 inch NPT connections, operating within -13 degrees F to 150 degrees F and up to 250 psi supply pressure.

Installation Notes

Installation is typically performed by a pipefitter or industrial maintenance technician familiar with compressed-air distribution systems. Depressurize and lock out the air supply before installing or servicing this unit. Ensure flow direction matches the arrow or inlet marking on the body, and apply appropriate thread sealant to NPT connections per shop practice. Follow applicable codes such as OSHA 29 CFR 1910.147 (control of hazardous energy) when working on pressurized pneumatic systems.
