The AV1020WV runs on compressed air and tap water, Challenger Lifts officials said.  The lifting mechanisms are accessible from the surface and require minimal maintenance--grease four fittings once a year.

AV1020WV works with no environmental, maintenance, and corrosion problems that typically occur with traditional in-ground lifts.  Since it's powered by air pressure, there are no noisy, energy-consuming motors, which saves money on installation costs.

The EnviroLift features:

•Large 8-1/4-inch double-walled, anodized aluminum pistons that provide stability and corrosion-resistance.

•Air-actuated water control valve for positive ascent and descent.

•An 80-inch rise and descent capability that provides maximum head room for working underneath vehicles.

•Versymmetric three-stage arms that lift both symmetrically and asymmetrically within the same service bay to maximize service capabilities and revenue potential.

•A drive-through width of 87 inches that allows easy vehicle drive-on.

•Double Telescoping Screw Pads reach multiple vehicle pickup point heights that reduce the need for adapters.
