Standard Air Opener
Another choice for an air opener is the Airlift Standard Air Opener. The Standard Air Opener is constructed of anodized aluminum cylinders, stainless steel brackets and rods, and PVC pistons.
Mounted on the side of the door, the Standard Air opener uses two pistons to drive a chain that turns the door shaft. This in turn opens and closes the door. This type of opener is ideal for doors with a highlift track.
CAUTION: Air Operators can be adjusted to operate at speed much faster than typical electric openers. These openers are for commercial use only. Proper safety devices should be installed and monitored at all times. Down travel speed should be adjusted to slow and safe immediately upon installation.
