Pneumatic operation requires an 80 psi air supply and a single phase 240 volt power supply terminated within a fused isolator approximately one metre from the opening. A feature re of having pneumatic flexible doors is that each leaf has a separate cylinder so that opening and closing cycles can be regulated independently, whereas, with the electric system there is one motor that drives both leaves through a constant speed reduction gear which cannot be varied.

Electric operation requires a 440 volt, 3 phase neutral & earth power supply terminated within a fused isolator approximately one metre from the opening. In the event of a power failure, the doors can still be used as conventional 'crash' doors as they are driven though the vertical spring unit mechanism at the top of the door tube. Both systems are supplied complete with a control panel which incorporates an adjustable timed return facility that enables the doors to close automatically once the desired stand open time has elapsed.
