Compressed Air Pressure Boosters
Ensure sufficient pressure to operate air-powered tools and machines. Pressure boosters compress the air supply, which increases air pressure. To maximize performance and service life, install a filter inline before the booster to remove particles down to the maximum particle size. Do not use boosters for tank capacities larger than specified.
Adjustable boosters have an integral regulator so you can fine-tune the output pressure. They come with pressure gauges on the inlet and outlet.
Boosters with 3/8 NPT female inlet and outlet require compressed air to operate—they have a drive inlet and a pilot inlet that control the booster.

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.
