Mars Air Systems requires
a control panel for all Unheated, 3-phase, Standard Series (STD2) and Phantom (PH10) Air Curtains. It is also required for 115/1/60 and 208-230/1/60, 3-motor and 4-motor units. This control panel is externally mounted and comes standard with automatic plus manual on/off control.
This control switch/panel pairs perfectly with the J0040 door switch for automated on/off control of your 1/2 horsepower, 4-motor, 460/3/60 STD2 and PH10 air curtains.
