PointZero 1/3 HP Double Piston Airbrush Compressor with Air Tank, Regulator, Gauge and Water Trap - Quiet Professional Pump

  • ...ately 60 psi, then cycles off until the pressure drops to 40 psi, when the unit restarts. This power-saving feature reduces motor wear while maintaining enough pressure to operate most airbrushes. In the secondary switch position, the compressor runs continuously, when maximum output is desired (up to 85 psi)..
  • Constant pressure with zero pulsation: Air is drawn from the large, 3.5-liter (1 gallon) air storage tank, providing constant, regulated pressure and smooth output. This eliminates the pressure pulsations common with tankless compressors. Tank features a threaded drain plug for purging any accumulated water and a pressure-release valve for safety (release pressure prior to draining)..
  • Includes 7 bonus airbrush guides: As a bonus, includes access to 7 exclusive e-Book airbrushing guides: Top 8 Cake Airbrushing Tips, Guide to Airbrush Cake Decorating, Developing Basic Artistic Skills, 10 Essential Airbrushing Tips, Airbrushing Strokes and Techniques, Airbrush Cleaning Manual, and the Airbrush Lettering Guide.
