The D500SR airbrush compressor is perfect for any hobby or artist airbrush. The maximum operating pressure will be about 35 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.
