A pneumatic vacuum elevator that travels through a self-supporting transparent tube, requiring no traditional shaft, pit, or machine room.
Full Definition
A shaftless elevator — most commonly realised as a Pneumatic Vacuum Elevator (PVE) — operates by air pressure differential: a vacuum above the car lifts it, while controlled air release lowers it. The polycarbonate or acrylic tube is self-supporting and installs in existing buildings with minimal structural modification. No pit or machine room is required. Typical capacity: 1–3 persons (160–250 kg). Maximum travel: 3–4 floors. Speed: ~0.15 m/s. Limitations include lower speed and higher energy consumption per trip compared to traction systems. Notable brands: Pneumatic Vacuum Elevators LLC, Aritco, Garaventa.
