The Easy Air Frame System consists of seamless TPU inner tubes that are high frequency welded on the ends. The inner tubes are protected within reinforced twin walled outer jackets. Inflation is achieved by an external single valve system that incorporates isolation valves which isolate each section of the main air frame. This also helps to preserve the air pressure within each inner tube. For rapid deflation, simply open the isolation valves and release the the air pressure from external multi-valves which are located at the front of the awning. The Easy Air Frame is only inflated to 8 -10 psi (max.) and makes the pitching of the air awning fast and simple.
