If you are thinking of installing an elevator in your home and you have read a bit about different types of lifts, you know that our technology is unique in the elevator industry.
Our vacuum elevators operate under the principles of pneumatics and vacuum, both different but related, which together result in pneumatic vacuum technology, which the gives name to our home lifts.
Pneumatic (Greek πνεῦμα “air”) is the technology that uses air as a mode of transmission of energy to move and function mechanisms, in our case the car of our vacuum elevators.
Vacuum (Latin vacīvus) is described as a closed cavity where air pressure or other gases are less than atmospheric pressure.
But … how are these two principles applied in our vacuum elevators?
The pneumatic vacuum elevator is formed by a cylindrical vertical shaft, and a car which moves inside.
For ascending operations, the vacuum system (4) on the top of the elevator, draws air from above the seal of the car on the interior of the cylinder (1) creating a low pressure area (3) located above the cabin seal. (2). At the same time, atmospheric pressure (greater than the low pressure system above the cabin seal) enters into the ground floor cylinder through holes/perforations on the ground floor cylinder panels, furthermore creating lift.
To descend, there is a valve inside the vacuum motor system (4) that regulates the entry of air into the cylinder restoring pressure, lowering the car smoothly without consuming energy, also making the vacuum elevator an ecofriendly lift.
