Wilkerson F18-03-SG00B Compressed Air Filter 3/8 Npt

Product Description

The WILKERSON F18-03-SG00B is a general purpose compressed air filter designed to remove particulates and contaminants from compressed air lines. It accepts a 3/8 inch NPT port with NPT end connections and delivers a rated flow of 78.00 standard cubic feet per minute (SCFM). The filter uses sintered polyethylene filter media and features an automatic drain for continuous condensate removal without manual intervention. A polycarbonate bowl with a nylon bowl guard provides visibility of the collected liquid level. The integrated sight glass confirms bowl status at a glance. This filter is installed by industrial maintenance technicians, pipefitters, and HVAC-pneumatic system specialists on compressed air distribution systems.

The F18-03-SG00B belongs to the Wilkerson Series 18 modular filter line. Its modular connection design allows it to be combined with regulators and lubricators in a filter-regulator-lubricator (FRL) assembly. This filter is suited for general purpose point-of-use or inline compressed air filtration in light industrial, commercial HVAC, and pneumatic tool supply applications where moisture and particulate control are required upstream of sensitive equipment or controls.

Installation Notes

Installation should be performed by a qualified pipefitter, industrial maintenance technician, or pneumatic systems technician. Depressurize and isolate the compressed air line completely before removing or installing any inline filter component. Verify that all NPT threaded connections are sealed with appropriate thread sealant per site and code requirements. Do not exceed the rated operating temperature or pressure range for the polycarbonate bowl — consult system documentation before installation in elevated-temperature environments.
