Pneumatic devices

tire inflation unit


The pneumatic inflating unit automatically inflates and deflates tires of four-wheel chassis. Each wheel can be inflated and deflated independently, according to required pressure levels. In the case of puncture of one of the tires, the unit compensates the leakage by keeping the continuous air flow.

The unit also allows for inflation and deflation on the go. Tire pressure adjustment between 1 and 8 bar.
