Compressed Air Flow Boosters


Adjustable	Fixed

Fixed with Flange

Create a high-flow air stream from your compressed air supply. Flow boosters draw in ambient air, which amplifies compressed air flow. To maximize performance and service life, install a filter inline before the booster to remove particles down to the maximum particle size. Use hose clamps (not included) to connect hose or duct to the inlet or outlet. Boosters with flange mount easily near your equipment.

Adjustable—Adjustable boosters allow you to fine-tune the flow—rotate the knurled ring to change the amount of ambient air drawn into the booster.
