garage door openers & controls
How Supralift II ™ Works Supralift™ Air-Powered operators utilize a dual cylinder/piston assembly mounted to the door track. The air valve and regulator located between your compressor and operator directs air to either the open or the close cylinder which pushes the piston/rod assembly down. The drive chain is attached to the top of each piston rod and loops over the sprocket on the door’s torsion shaft. On the “open” signal, compressed air drives the “open” piston/rod downward. The chain rotates the sprocket, rotating the torsion shaft. The door responds with a smooth, fast motion to the open position. On the “down” signal the door closes with a cushiony stop, preventing cable spooling and unwanted door jerking.
