Hydraulic System Requirements N/A

All hydraulic ratings and pressures are at the machine and do not take into account the pressure drops of individual hydraulic systems. These pressure drops need to be taken into account and added to the rating of the hydraulic pump and components. 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, the continuous hydraulic load when the compressor is running, the duty cycle and ambient operating temperatures, and any other hydraulic equipment that may share the same hydraulic supply system (Vanair® recommends a dedicated pump and hydraulic circuit).

Additional Information N/A

No other brand of hydraulic driven above deck systems can even come close. The RS85 is designed with an aluminum canopy, base, and air end to reduce vehicle weight and to protect against rust. Its compact footprint increases deck space on your truck, and its sound attenuation design decreases noise levels for comfortable operation. Featuring an easy to use on/off button LED control panel, the RS85 comes with the standard Vanair® Lifetime Warranty on its air end.

Cold Weather Option.

Note N/A

Standard side-mount receiver configuration.

185 CFM at 150 PSI systems may require additional cooling.

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