How Vacuum Elevators Work

A clear tube standing in a living room, with a capsule gliding silently between floors, looks like science fiction. The vacuum elevator is in fact a very simple machine, and that simplicity is why it has become popular for existing homes.

The parts

  • A vertical cylinder made of clear panels on an aluminum frame
  • A cab that fits closely inside it, with a seal around the top
  • A head unit above the tube containing turbines and valves

Going up

The turbines draw air from the tube above the cab. Pressure there drops. The air below, still at normal pressure, pushes the cab upward. At the chosen floor, mechanical locks engage and hold it.

Coming down

A valve admits air above the cab in a controlled way. The pressure difference shrinks and the cab descends smoothly. The turbines do not need to run on the way down.

If the power fails

The cab descends slowly to the lowest level, and the door can be opened.

Why homeowners like it

  • No pit, no hoistway and no machine room
  • Installation in days
  • A footprint of only a few square feet
  • Transparent walls that keep rooms bright
  • Modest energy use, since descent needs no power

What to be aware of

  • Cabs are round and compact. Larger models carry a wheelchair.
  • The turbines can be heard during ascent
  • The elevator is on display, so it should suit the room
  • Clearance is needed above the top floor for the head unit

Sizes

Models range from a one-person cab to a wheelchair-accessible one. Choose with the future in mind.

Is it right for your house?

It is the natural choice when you want an elevator in a finished home without major construction. For the largest cab or a concealed installation, a traditional elevator is better. Both are on our home elevators page.
