The WILKERSON L28-04-KK00B is a standard compressed air lubricator engineered for use in pneumatic systems where consistent oil mist delivery is required to protect downstream tools, actuators, and valves. Part of the Series 28 product line, this unit features a 1/2 inch NPT port and is rated for 110 CFM airflow. The aluminum die cast body provides structural durability, while the polycarbonate bowl with integrated bowl guard allows visual monitoring of oil level during operation. A built-in sight glass confirms active lubrication. Nitrile seals ensure compatibility with petroleum-based lubricants across a broad range of service conditions. Licensed mechanics, pneumatic system technicians, and industrial maintenance personnel typically specify and install this unit.
This lubricator is suited for use in industrial compressed air distribution systems, assembly lines, machine tool applications, and maintenance shops where air-driven equipment requires continuous lubrication. It supports modular connection, meaning it can be combined with compatible WILKERSON Series 28 filter and regulator units to form a filter-regulator-lubricator (FRL) assembly. The manual drain design is standard for controlled maintenance environments where scheduled service intervals are already in place. The unit handles operating temperatures down to 14 degrees F, making it functional in cold service environments such as unheated warehouses or outdoor enclosures during mild winter conditions.
Designed as an OEM-style replacement or direct-fit unit for Series 28 pneumatic FRL systems requiring a standard lubricator with 1/2 inch NPT porting and modular connection capability.
Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize and lock out the compressed air supply completely before removing any existing lubricator or installing this unit. Verify that upstream line pressure and CFM demand are within the rated operating range of this lubricator before placing the system back in service. Use appropriate thread sealant on NPT connections and confirm all bowl fittings are properly seated before pressurizing.
