PRINCIPLES OF OPERATION

Technology

The pneumatic lift combines a smooth vertical cylinder with a coaxial car that moves up and down through air suction. The vacuum lift operates on the upward push generated by the difference between the atmospheric pressure above the car and the atmospheric pressure below it.

Turbines operating as exhaust fans create the depression (vacuum) needed to lift the car, located at the top of the lift.

  • The piston gear surrounded by a sliding air-tight seal allows an almost frictionless movement and hoists the car due to the pneumatic depression generated on the upper part.

  • A valve regulating inflow of air controls the pneumatic depression, enables descent and controls the speed of the car.

  • The lower part of the shaft is open to ensure free entrance of air at atmospheric pressure.

  • At each floor or level, perimeter seals on the door are self-sealing due to the action of the atmospheric pressure.

  • The car has locking devices to stop at the upper and lower limits of travel.

  • A safe braking device (chute) activates in case of free fall.

THREE MAIN PARTS OF

Pneumatic Home Lift

EXTERIOR CYLINDER

The cylinder is a transparent self-supporting tube, built around a specially designed aluminium structure. The tube walls are made of curved polycarbonate sheets. The tube consists of modular sections, which can be easily fitted together. The steel roof ensures airtight closures with suction valves and inlets.

ELEVATOR CAR

The car runs inside the cylinder on rails or columns that are part of the cylinder’s self-supporting structure. The car’s walls are made of transparent polycarbonate panels. The car also has an anchoring system that activates when it reaches the indicated floor, provides precise but smooth stops, and locks the car mechanically.

SUCTION ASSEMBLY

The suction assembly, or “Head Unit”, sits on top of the cylinder, where the turbines, valves, and controls are located. The control cabinet is a metal box housing with a PVE controller board and other electrical devices. The head unit is built and placed on either the same tube that holds the car (standard), or separately (split unit) at distances of up to 30 linear feet (10m) from the lift. The suction assembly frame is made of fibreglass or steel, depending on the model.
