Air Over Oil Intensifiers

Get the force and stability you need by converting air to hydraulic pressure without the need of a hydraulic system. Models ranging from 5:1 to 36:1.

Air/Oil Intensifiers convert typical shop air, 80-100 psi, into hydraulic pressure. The benefit to you is using existing shop compressed air and boosting pressure by the specified ratio to achieve the desired hydraulic force. It will potentially reduce the need for additional hydraulic caliper disc brakes for your braking application, other system components, and save money.

How They Work

Air/Oil Intensifiers convert shop air, up to 100 psi, into hydraulic pressure. Air pressure applied to the air inlet displaces a piston of
pre-defined ratio which is transferred to the hydraulic fluid stored within the intensifier housing. An internal spring retracts the piston drawing in hydraulic oil from a reservoir as needed. The vented spring chamber eliminates back pressure.
