The Leading Air Compressor for the Tire and Mechanic Truck Industry Now 40% Lighter!

The new RC40-L was designed with an aluminum air end and canopy to reduce weight on the vehicle without compromising quality. Offering a solid 40 CFM of power, the rust resistant, durable, reliable, and powerful RC40-L features a reversible hinged hood, easy to read control panel, and easily accessible service panels to provide flexibility of where to mount the unit on the vehicle. Leading the industry by providing hydraulic cooling assist for additional hydraulic systems, the RC40-L is also available with a cold weather package and the option of an LED electronic control panel.

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).
