The Oasis Adjustable Pressure Switch is built to give you precise control over your Oasis XD3000 or XD4000 compressors. Installed directly into your air tank, it regulates when the compressor turns on and off based on system pressure. It comes pre-set to activate at 110 PSI and shut off at 150 PSI, but includes an adjustment screw that lets you fine-tune the range from 100 to 250 PSI in 30–40 PSI increments. This flexibility makes it ideal for dialing in custom pressure settings across a wide range of onboard air applications. The switch uses a standard 1/4" NPT male thread, making installation simple and compatible with most air tanks. Whether you're powering train horns, air tools, suspension systems, or other pneumatic gear, this switch ensures reliable compressor cycling and long-term system performance.
