A pneumatic lift, also known as a vacuum elevator, is a type of home elevator that works using air pressure instead of cables or pulleys. It operates inside a vertical, air-tight tube.
Here’s how it works:
- To go up, the system reduces the air pressure above the elevator cab, creating a vacuum that gently pulls the cab upward.
- To come down, air is slowly released into the tube, and gravity lowers the cab smoothly.
Pneumatic lifts are popular in homes because they are compact, energy-efficient, and easy to install. They don’t need a machine room or deep pit, making them a great option for modern houses or retrofitting.
