This BLACK WIDOW BY SPECTRUM® Professional Airbrush Compressor Kit has a pressure control for each line that lets you operate two airbrushes simultaneously, making it ideal for the most demanding airbrush work. Two independent pressure regulators deliver the exact paint flow you need so each airbrush can operate at a different output setting. This kit includes a 1/8 in. quick-connect fitting for easy attachment and two convenient airbrush holders to store the airbrushes when they’re not in use.
