Grex Micro Air Control Quick Coupler Valve - G-MAC-B

The G-MAC gives you precise unrestricted control of airflow for your airbrush right at your fingertips, allowing you to make real-time air adjustments while you're painting.

The G-MAC.B includes 1 G-MAC (adapter included to attach the G-MAC to your Badger air hose with a quick-connect coupler on the other end) and 1 quick connect plug that attaches to your Badger airbrush.

Compatible with all brands and types of airbrushes, giving you the freedom to put airflow control on any of your airbrushes, instead of being restricted to a specific airbrush.

Comes as a quick connect air coupler allowing you to easily switch between airbrushes to give every airbrush the ability to control airflow.

Attaches to the air inlet of your airbrush. This provides better balance compared to having the airflow control below the head of the airbrush. You also don't have to worry about accidentally moving the head of the airbrush while you're simultaneously adjusting pressure and spraying.

Designed with a large dial to allow easy air pressure adjustments. This is particularly helpful when spraying and adjusting air pressures simultaneously.

Capable of achieving fine adjustments to give precise airflow control. Three full dial rotations to change from zero airflows to full airflow.

Ideal for stippling applications. Accurately control stippling size while you're painting in real-time. With a simple turn of the dial, the G-MAC gives you the ability to produce coarse stippling effects to full atomization.

For fine lines and detailed work, use the G-MAC to precisely produce optimal airflow for infinite control of paint output.

Fully open the G-MAC to allow maximum airflow for wide background spraying and to quickly clean your airbrush during color changes.
