The pneumatic elevator lets your home sport that futuristic look of transparent tubes transporting people in science fiction films. With this kind of equipment, you and your family can now enjoy the reality of being transported to the different floors of your residential buildings in these high-tech tubes that do not need cables, pulleys or pistons.
There would be no visible material supporting the cab of this vacuum elevator because it is actually air that is performing this function. Plastic and aluminum are used because minimizing the weight is vital in the pneumatic elevator where the difference in air pressure between the top and bottom of the cab is responsible for lifting it or bringing it down.
The Principle Behind This Elevator
The basic principle in the design of the pneumatic elevator is that a long transparent tube contains the cylindrical elevator car with a diameter that is slightly smaller than that of the bigger tube. The floor and ceiling of the elevator car are airtight and a vacuum pump is allowed to suck the air out of the top of the long tube. This will cause a vacuum to form at the top of the tube.
The air pressure underneath the floor of the car will then slowly push it up as the difference in air pressure between the top and bottom increases. To lower the car, the vacuum pump is turned off. As air returns to the vacuum space, the difference in the air pressure decreases and the elevator gradually goes down. With this system, it can be seen that there is no chance for the car to drop abruptly.
Why Should You Choose This Kind of Elevator?
Some of the benefits offered by this particular design for home elevators include solenoid valve ease of maintenance, operation and installation when compared to the usual residential elevators. There is no need to dig a pit and hoist way so that these are appropriate for homes that have already been constructed.
Another vital advantage of this personal elevator gizmag that may not be surpassed by other designs is the safety that it provides. As can be seen from the above discussion on how it works, it is impossible for the elevator car to go into free fall. In addition, if a power failure occurs, the car cannot drop suddenly but only slowly as the air gradually returns to the vacuum space.
Another essential advantage of the pneumatic elevator is, of course, its futuristic appearance. Friends will surely be amazed by its looks and this will also increase the market price of your home. This market value will be further enhanced when buyers learn about its inherent safety features.
Another essential benefit is that electric consumption is much less than for conventional elevators because it does not require electric power to bring down the elevator and it also requires less power to go up. Maintenance is also less costly because lubrication is not required and there are no complicated parts.

These are also called Single Action Cylinders. Cylinders come in a variety of types and may either be pneumatic cylinders, electro pneumatic cylinder, hydraulic cylinders or electro hydraulic cylinders. Double Acting Cylinders (DAC) employ the force of air to move in two ways, in an extend stroke and a retract stroke. Double Acting Cylinders have two ports, one for outstroke and one for in-stroke.
Pneumatic and hydraulic damping systems contain pneumatic cylinders or hydraulic cylinders which employ a steel piston, a piston rod, a cylinder barrel setup to help deliver the damping effect. As compressed air or fluid moves into a pneumatic or hydraulic cylinders, it pushes the piston up or down through the length of the cylinder. The reflex action of the piston is either activated by either the compressed air or by a spring mechanism, which brings back the spring to its original position.
