Designed for spraying problematic materials, diaphragm, or membrane, spray gun is equipped with diaphragm instead of needle seal packing, which shows majority of wear from use of aggressive materials.
Diaphragm ensures that all wetted parts are separated from air components so spray gun is virtually leak-free.
Material needle does not go fully through gun; instead, gun is operated via pneumatic pulse that relieves pressure of rear spring located in air compartment.
Design significantly lengthens service life and keeps repair costs low.
