The Inertia operator is a compact, two-fisted operator that uses one arm to quickly slide large doors, then gently but firmly slows the motion with the other arm. The Inertia operator is commonly used is cattle auction houses and industrial warehouses with large sliding doors up to 30 feet wide.
Air-Lec Swing operators are adaptable to almost any swinging or folding door. The swing operator is most frequently used for cold storage applications such as large freezer doors. This product is ideal for doors about 5 feet wide with two sizes available for doors over and under 500lbs.
The Over-Center is another Air-Lec sliding operator that is widely used in traffic and fire door applications. The design uses a pneumatic piston in the center to slide doors smoothly across their tracks. This operator is available for doors up to 6 feet wide and can handle weight up to 1,200lbs.
Door Operators Built to Last
I highly recommend the Air-Lec opener. I have used them for over 40 years. The units are reliable, safe and trouble free.
