Apart from price, there are many points to consider when buying an,Airbrush compressor, such as output capacity, noise level and air filter specifications. Regardless of your final choice, following correct compressor setup procedure can ensure years of trouble-free service.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

  • Air hose fittings
  • Teflon tape
  • Wrenches
  • Compressor water filter
  • Special fitting equipped with bleed hole
  • Precision air regulator
  • Dish soap
  • 1/2-inch paintbrush
  1. 1

    Connect the airbrush to the hose with the correct fitting. Cover the male thread by stretching Teflon around the threads so that the thread profile is visible. Stretch the end until the tape breaks, and smooth the edges into the threads. Attach the female coupling. Tighten the coupling with two opposing wrenches. Do not overtighten this or any other element of the system.

  2. 2

    Mount a water filter either to the air receiver or directly to the compressor air outlet if the unit does not have an air receiver tank. Install a special fitting equipped with a bleed hole to prevent pressure surges between the compressor and the filter when connecting directly to the compressor outlet. Wrap the connecting threads with Teflon tape to prevent leaks.

  3. 3

    Install an air regulator between the water filter and the airbrush. Follow the manufacturer's instructions and bolt the regulator to a stable part of the compressor or the compressor frame with the mounting bracket supplied. Wrap the fitting with Teflon tape prior to installation.

  4. 4

    Wrap Teflon tape around the male adapter on the end of the airbrush hose. Connect the hose to the precision regulator with two opposing wrenches; this ensures correct air pressure at the nozzle.

  5. 5

    Prepare a mixture of soapy water to test for leaks. Turn the compressor on. Apply soapy water to all the joints with a paintbrush. If bubbles form, tighten the fittings a quarter turn or until the leak stops. Turn the adjusting knob on top of the regulator to its highest position before testing the joints upstream of the regulator. Apply soapy water to the joints. Press the operating button on the airbrush up and down a few times to create maximum air surge while monitoring the joints for leaks.
