A vacuum elevator is currently one of the most energy-efficient elevator systems in the world. And we at Nibav home elevators are proud to be the first ones to introduce it in Australia. Our range of vacuum elevators is elegant, energy-efficient, and the safest house elevators in the market right now. They have passed the strictest global standards of security and are economical with almost zero civil work going into their installation.

Since vacuum technology is relatively new in Australia, here is a simplistic breakdown of how it works.

How Vacuum Elevator Work

The Vacuum Residential Elevators combines a linear vertical cylinder with a lift car that moves up and down through the power of air suction. The operation of the elevator is based on the upward push generated by the difference between the atmospheric pressure on the top of the car and the under the car. The vacuum created as a result of the pressure difference is achieved by turbines operating as exhaust fans which are located at the top of the elevator. This is used to move the lift car upwards.

A sliding air-tight seal that surrounds the piston gear allows an almost frictionless movement to hoist the car due to the pneumatic depression generated on the upper part. The inflow of air is regulated by a valve to control the pneumatic depression, enables descent, and controls the speed of the car.

On the lower part of the shaft, it is open to ensure the free entrance of air at atmospheric pressure. A perimeter seal is placed on each floor to create a self-sealing atmospheric pressure. The lift car comes with traditional locking devices to maintain the pressure difference required to move between floors. In case of a fall, a chute is activated as a self-braking mechanism.

The Components of a Vacuum Elevator

Outer Cylindrical Shaft

The cylinder comes in the form of a self-supporting tube, which is mostly transparent. It is built around a specially designed aluminum structure to provide structural integrity. The tube walls are made of high-end, curved polycarbonate sheets that are extremely sturdy. The tube also consists of modular sections, which easily can fit into one another. The roof of the tube is made of steel and ensures air-tight closures with the corresponding suction valves and inlets.

Internal Lift Car

The car runs inside the cylinder on rails or columns, which are part of the same self-supporting structure of the external cylinder. The walls of the car are also made of transparent polycarbonate panels, like the external cylindrical shaft. The lift unit is also equipped with an anchoring system that activates on reaching the indicated floor to provide precise but smooth stops and locks the car mechanically.

Head Unit

The head unit, or the suction assembly, is on the top of the tube/cylinder, where the turbines, the valves, and the controls are located. The control cabinet is a simple metal box that is housed within a PVE controller board and other electronic devices. The head unit is built and placed on either the same tube that holds the car, for the standard model, or separately, for the split unit, at distances of up to 30 linear feet (10m) from the lift. Depending on the model, the frame of the suction assembly is made out of either fiberglass or steel. However, you can rest assured that every unit of the home elevator that comes out of Nibav is extremely safe.

As we mentioned earlier, our experts in residential elevators have successfully brought this high-end technology to home lifts in Australia. We have a wide range of elevators for you to choose from and combine that with easy installation and support services. To know more about our range of home elevators, please get in touch with us now.
