• 30A, 120V, 175PSI
• Heavy duty pin and sleeve contacts provide reliable connection over years of insertion/eject cycles
• Air connection made through a brass fitting containing a shut-off valve. Shut-off valve opens when plug is inserted to supply air pressure to the vehicle. Shut-off valve closes automatically when plug is ejected sealing off the air supply air
• Upon sensing engine start, the plug ejects from receptacle and away from vehicle path; eliminating dangerous severing of cord
• Air-Electric energizing is delayed until detector pin senses plug is inserted, eliminating terminal arcing

The Super 30 Auto Eject -Air Electric, adds an air pressure connection to the popular Super 30 Auto Eject. Thus, in one connection the vehicle is supplied with 30 amperes of electric power and an air pressure line to recharge the vehicles air brake reservoirs. A standard 4 pin connector is modified to replace one of the electrical pins with a specially designed air connection. The Air-Electric connector is part number 091-169-CON-4P-120. The Air-Electric connector contains a shut-off valve that is opened when the connector is mated with the Auto Eject. The valve closes when the plug is ejected and retains the supply air. A novel plug detector closes and opens the A.C voltage circuit after the mating connector is inserted and before the connector is ejected. This eliminates arcing at the connector contacts and assures long contact life.

As with all Auto Ejects the Super 30 Auto Eject -Air Electric, is connected to the starter circuit so that ejection occurs when the engine is cranked.
