The Oxygen Speed annexe uses Oxygen Airframe Technology and zips on to the left hand side of the Oxygen Speed 1, 2 and 3 carvan porch awning. The inflatable annexe provides superb additional sleeping space for two people, or creates extra storage space. The annexe comes equipped with a double inner tent, which comfortably fits a double air bed. The annexe uses the original Dynamic Speed Valve in one Airframe tube, which makes it exceptionally quick and easy to erect. The 150 Denier Double Rip-stop Acrylix fabric is incredibly strong yet lightweight; providing the optimum lightweight to strength ratio. Protected with Sun Pro UV, the material will not fade or go brittle, it will maintain its quality for up to three times longer than any unprotected material.
Condensation, a reoccurring problem which is impossible to cure is aided by the use of Vortex Vents which help to circulate the air in the awning and reduce condensation.
