Wilkerson F28-04-SK00B Compressed Air Filter 1/2 Npt

Product Description

The WILKERSON F28-04-SK00B is a general purpose compressed air filter designed to remove liquid water, bulk contaminants, and particulates from compressed air lines. Part of the Series 28 modular filter family, it handles up to 120 standard cubic feet per minute (SCFM) and connects via 1/2 inch NPT end connections. The filter uses a sintered polyethylene filter media element to capture contaminants before they reach downstream equipment, tools, or pneumatic controls. A polycarbonate bowl with nylon bowl guard allows visual inspection of accumulated condensate. A manual drain provides straightforward bowl evacuation. Licensed HVAC technicians, pipefitters, and industrial maintenance professionals install this filter as part of compressed air treatment systems.

The F28-04-SK00B suits general purpose compressed air applications in light industrial, commercial, and mechanical room environments. It is well suited for point-of-use installation ahead of pneumatic actuators, air tools, control valves, and instrumentation. The modular connection design allows integration with other Series 28 components such as regulators and lubricators to build a filter-regulator-lubricator (FRL) assembly. The manual drain and integrated sight glass support routine service without system shutdown in many configurations.

Installation Notes

Installation should be performed by a qualified pipefitter or compressed air system technician. Depressurize and lock out the compressed air line before removing or installing the filter. Mount the filter with the bowl oriented vertically downward to allow proper condensate collection and drainage. Follow applicable facility safety procedures and local mechanical codes when working on compressed air distribution systems.
