The Pneumatic Vacuum Elevator is a cheaper alternative to conventional elevator, but it is not cheaply made.
The Pneumatic Vacuum Elevator creates a vacuum at the top of a polycarbonate tube which is the shaft of the elevator and the air pressure moves the elevator up and down. Because of this it does make the elevator significantly slower than others, but it may be a great option for the elderly or disabled, or to anyone who simply likes to enjoy a pleasant elevator ride.
