Pneumatic bollards offers the highest standard of anti-ramming and security protection. Taking as little as 2 seconds to reach the fully raised position, these bollards can be used in the most demanding locations where high-volume traffic flows must be managed. These bollards are often combined with light arm barriers to provide maximum deterrence and safety. With a hard-wearing stainless steel finish, the bollards are engineered to meet the DOS and PAS standards for anti-ramming and are used extensively to protect sensitive government and military locations as well as civilian compounds. Bollards can be operated at very high speeds and when combined with a light arm, the air pressure can be used to simply and accurately synchronize with other elements in the system. The use of air pressure also significantly reduces the wear and tear on the components and provides years of maintenance free use. With a patent-pending mechanism for releasing the internal piston, the bollards can be maintained without disassembly and if necessary, the entire unit can be removed without the need for digging out the foundations.
