Product improvement is a continuing goal. Design and specifications are subject to change without notice or obligations.

Ratings above are approximate and are based on 120° F hydraulic fluid temperature. Add 400 psi minimum to hydraulic requirements for hydraulic system continuous pressure ratings. Machine hydraulic relief valve is set at 3200 psi. Consult Vanair for specific details.

*150 psi kit includes additional cooler. Consult factory for over 185 CFM.

Hydraulic System Requirements

Vanair highly recommends consulting a hydraulic supply expert for specifying the correct hydraulic pump size and type, oil reservoir size, hydraulic cooler, hydraulic pressure relief, and other hydraulic supply components for your application. Please take into consideration the following:

The hydraulic flow and pressure requirements of the air compressor
Keep in mind that when the compressor is running there is a continuous hydraulic load
The duty cycle and ambient operating temperatures
Other hydraulic equipment which may share the same hydraulic supply system (Vanair recommends a dedicated pump and hydraulic circuit)
