How Often Does A Vacuum Elevator Require Maintenance

One manufacturer reports that vacuum elevators require maintenance only once every five years to replace the main seal

Vacuum elevators, which operate by manipulating air pressure in a vacuum tube, require few moving parts and no pit excavation or machine room, so they are easy to install and require little maintenance. In fact, one manufacturer reports that vacuum elevators require maintenance only once every five years to replace the main seal, or every 15,000 lifts, compared to once a year for a traditional home elevator. The cost of maintenance can quickly eclipse the original installation cost for a traditional elevator, so vacuum elevators enable you to save hundreds on maintenance costs.

Vacuum elevators are sleek tubes that use the clear polycarbonate tube as a shaft, providing passengers with a clear view of the home as they travel. Operation is very simple: the elevator creates a vacuum at the top of the tube, and air pressure moves the cab up. Descent is even easier, optimizing gravity and controlled air flow, allowing the cab to descend slowly and safely without using any energy.

Vacuum elevators contain three main parts: the hoist way cylinder, the vacuum elevator car, and the suction assembly.

The cylinder is the tube made of sheets of polycarbonate in modular lengths that fit together easily. The doors are made of the same material, are airtight, and are provided with safety magnetic locks. The roof of the tube is made of steel to ensure a tight core with suction valves and air inlets.

The vacuum elevator car is made of transparent polycarbonate and mounted on a steel frame. There is an air joint on the cab roof that ensures normal air pressure and air conditions for the passengers with an anchoring system that activates when reaching the desired floor to ensure an exact stop.

The suction assembly can be built on the same tube that holds the cab or separately at distances up to 30 feet from the cylinder. It holds a monophase motor.

When it comes to elevator maintenance, look for providers that offer maintenance plans that provide routine inspections, lubrication, and the replacement of minor and major parts. With a vacuum elevator, you can request a limited maintenance plan that doesn't require regular service.

The only downside to vacuum elevators is their slow-moving speed – six inches per second, their small cabin size – 20 inches in diameter, and limited weight capacity – 350 pounds. But for those who require an elevator in their home, including the elderly or disabled, a vacuum elevator is the right choice in terms of cost, power, and maintenance.
