How It Works

The air casters exist of a flexible rubber membrane that is fed by compressed air operating from 1 to 4 bar. A controlled leakage of the compressed air creates a thin air film between the floor and the air caster. The air caster can now float a few tenth of a millimetre above the floor with virtually no friction which makes it possible to move heavy loads and objects with relatively low force. It only requires 1 kg of pulling force to move a weight of 1,000 kg. 

For example

One single air caster with a 400 mm diameter has a capacity of 4.000 kgs!

The load itself is only raised by a few centimetres. Due to the relatively low flow, no dust cloud is created and the floor does not get damaged because there is no point-concentrated load. The noise level is also low due to the low pressure applied.

Step 1

The weight of the load is transferred to the ground via the landing pad.

Step 2

Compressed air is applied; the air caster’s membrane lifts the load from the ground.

Step 3

Air pressure overcomes the load’s weight; a controlled leakage creates an air film and it floats.
