All weather crash rated pneumatic bollards preferred
Palmdale, Ca (USA)
Federal buildings, corporate headquarters, courthouses, military bases, facilities and other complexes, from airports to seaports, that need to protect people and property are all proponents and users of Delta pneumatic bollards.
According to Hamm, there are several reasons for the increased popularity of pneumatic bollards. To begin with, the all-weather pneumatic controllers are proven reliable. They have stood up to six Syracuse winters at the federal courthouse and, likewise, six years in the heat of low desert at the Reagan Presidential Library. The U.S. Border Control prefers pneumatic bollards as they are a green solution since they use less horsepower and eliminate the grease and oil of either electro-mechanical or hydraulic units. Using a small compressor, they use less electrical current than electro-mechanical units plus provide longer runs than hydraulic versions. The Corps of Engineers highlights their low maintenance, appreciating their low sensitivity to dirt and grime.
Crash rated and tested with a 15,000 lb (6804 kg) vehicle going 50 mph (80 km/hour), Delta's pneumatic bollard systems operate individually or in groups up to ten and are used for intermediate level security applications. Individual bollards are up to 13.25 inches (336 mm) in diameter, up to 35 inches high (889 mm) and are usually mounted on 3-foot (0.9 m) centres.
