The Iwata-Medea pistol grip filter attaches directly onto the airbrush to supply clean and dry air. A clear filter bowl on this airbrush moisture filter lets you do a visual inspection of the moisture build-up. The built-up moisture can be effectively removed through a spring-loaded release valve, without the need to remove the filter off the airbrush. Its small, 5-micron filter element acts like a full-size filter operator. This Iwata filter can also double up as a handle when attached to an airbrush to help release muscle tension.
