Wilkerson WSA-03-FM0 Oil Water Separator Auto Drain

Product Description

The WILKERSON WSA-03-FM0 is a compressed air oil water separator designed to remove bulk liquid contamination from pneumatic systems. It uses NPT end connections and features an automatic drain for hands-free liquid discharge. Rated to 200 psi maximum working pressure, this separator handles liquid-to-gas separation duties in a compact body measuring 7.34 inches high and 3.35 inches wide. Weighing 2.8 pounds, it is sized for inline installation without adding significant load to existing piping. Licensed HVAC technicians, industrial maintenance mechanics, and plumbing contractors install this type of unit as part of a staged compressed air treatment train.

The WSA-03-FM0 is intended for installation downstream of air receivers and downstream of aftercoolers, where condensed water and entrained oil droplets are present in the airstream. It also serves as a protection stage ahead of refrigerant dryers and heatless regenerative desiccant dryers, shielding those units from liquid slugs that accelerate desiccant degradation. The 3/8 inch NPT thread size suits smaller distribution headers and branch lines commonly found in light commercial and industrial compressed air systems.

Key Features

• Automatic drain eliminates manual purging and reduces maintenance intervals
• 200 psi maximum working pressure suits standard industrial compressed air systems
• 3/8 inch NPT connections for straightforward inline installation
• Compact profile at 7.34 inches high and 3.35 inches wide minimizes footprint
• Suitable for liquid-to-gas separation, aftercooler drainage, and dryer protection applications

Compatibility

Designed for inline installation on compressed air systems requiring oil-water separation downstream of air receivers, aftercoolers, refrigerant dryers, and heatless regenerative desiccant dryers with 3/8 inch NPT connections rated to 200 psi.

Installation Notes

Installation should be performed by a qualified industrial mechanic or pipefitter in accordance with applicable local codes and the system manufacturer's guidelines. Depressurize and isolate the compressed air line fully before making any connections. Ensure flow direction matches the arrow or marking on the separator body. Verify that upstream piping is adequately supported so no load is transferred to the separator body or fittings.
