The D500SR oilless airbrush compressor with regulator & moisture trap is perfect for any hobby or artist airbrush. The maximum operating pressure will be about 25-30 PSI depending on airbrush being used. The D500SR is lightweight, easily mobile, and best of all quiet. The auto-shutoff feature turns the compressor off when the airbrush is not being triggered to increase compressor life. Included with the compressor is a 1/8″ BPS adaptor for competitor hoses.
