Being a very reliable alternative to the hydraulic road blocker, Optima PRR Pneumatic Road Blockers are an efficient way of solution if there is a threat of vehicle attack in addition to the control of vehicle access in high security applications. As the construction is completely the same with the hydraulic rising road blockers, the strength of the construction is the same. The number of pistons used per road blocker increases due to the low pressure achieved in pneumatic systems.

Drive unit is pneumatic, but in case of power failure road blocker can be lowered by air compressor. With the help of PLC controlled electronics, raise/lower function can be achieved by every kind of card readers, biometric readers like fingerprint or hand shape, radio control, on/off key switch etc. Besides, safety accessories like inductive loop detectors, flashing lights or red/green lights can be integrated to the system.
