Pneumatic Vacuum Elevators, LLC has created a series of air-powered, space-saving, “plug & play” elevators designed to be easily installed into home environments.
Ranging from a single-passenger to a three-passenger, wheelchair accessible model, the elevators—called Pneumatic Vacuum Elevators (PVE)—are self-supporting, and do not require equipment rooms or other additional spaces above or below the shaft. Similarly, the elevators are completely enclosed and are not built into the framework of the home around them, and thus it can easily be relocated.
During a PVE ride, air pressure is used to lift and gently lower the cabin using only about zero to 4.7 kilowatts of electricity, for descent and ascent, respectively.
According to the manufacturers, PVE machines have very few moving parts and do not require lubrication, so they only require maintenance about once every four to five years or 15,000 rides.
