GRACO 17W739 – Active Surge Suppressor, 1-1/2″, 304SS, 300 PSI

GRACO 17W739 – Active Surge Suppressor, 1-1/2″, 304SS, 300 PSI

Active surge suppressor with ‘Set and Forget’ pulsation minimization technology. Minimizes pulsation on factory paint circulation lines with active air pressure compensation that eliminates the need for periodic air pressure checks and manual adjustments. Features automatic self-adjustment that removes the need to manually adjust air pressure inside the surge suppressor when target fluid pressure changes.

Manufacturers concerned about paint line pulsation can set and forgetthe active surge suppressor. It automatically adjusts itself for peak performance in changing conditions. Once you setit up, you can forgetabout manual adjustments.

Works off shop air, eliminating need for and extra cost of high pressure charge air

Flushes cleanly and thoroughly in between colors

Saves space with pump-mount configuration

Backup seal keeps paint from leaking out, in case of diaphragm rupture
