Compressed Air Flow Boosters



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.
Adjustable boosters allow you to fine-tune the flow—rotate the knurled ring to change the amount of ambient air drawn into the booster.
Boosters with flange mount easily near your equipment.

Compressed Air Pilot Signal Flow Boosters

Use a low-flow air pilot signal with an air supply to produce flow up to 50 cfm to actuate valves and other air-powered system components. To maximize performance and service life, install a filter inline before the booster to remove particles down to the maximum particle size.
Boosters with a 1:1 air signal to output ratio maintain pressure between the air signal and the output.
Boosters with 1:3 and 1:6 air signal to output ratios increase pressure between the air signal and the output.
