Wilkerson B28-04-FKG0B Frl Filter Regulator 1/2 Npt

Product Description

The WILKERSON B28-04-FKG0B is a single-piece filter/regulator combination unit with an integrated pressure gauge, designed for compressed air line conditioning in industrial and commercial pneumatic systems. The unit filters particulates down to 5 microns while regulating downstream pressure, keeping air tools, actuators, and control equipment operating within their rated range. Built on an aluminum body with a polycarbonate bowl and integrated bowl guard, it handles supply pressures up to 150 psi and flows up to 200 SCFM through a 1/2 NPT port. A manual drain simplifies bowl maintenance during routine service intervals.

This filter/regulator is suited for installation on compressed air branch lines feeding pneumatic tools, cylinders, valves, and instrumentation in manufacturing, maintenance, and process environments. The Series 28 modular design supports inline expansion with compatible WILKERSON modular components. The included pressure gauge allows technicians to monitor regulated output pressure directly at the unit without additional hardware. Operating temperature range spans -13 degrees F to 125 degrees F, making it appropriate for most indoor industrial service conditions.

Key Features

• Single-piece filter/regulator design with integrated pressure gauge reduces installation footprint
• 5-micron filtration rating removes particulates that damage downstream pneumatic components
• 200 SCFM flow capacity supports high-demand pneumatic circuits
• 150 psi maximum supply pressure with 1/2 NPT end connections
• Polycarbonate bowl with bowl guard provides liquid level visibility and impact protection
• Manual drain for controlled condensate removal during scheduled maintenance
• Modular connection compatibility allows integration into multi-unit FRL assemblies

Compatibility

Designed as an OEM-style replacement or new-installation filter/regulator for compressed air systems requiring 1/2 NPT connections, up to 150 psi supply pressure, and up to 200 SCFM flow capacity. Compatible with WILKERSON Series 28 modular FRL system components.

Installation Notes

Installation is typically performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize and lock out the compressed air supply completely before installing or servicing this unit. Mount the unit vertically with the bowl facing downward to ensure proper condensate collection and drainage. Verify that downstream system pressure requirements fall within the regulator adjustment range before placing the system back in service.
