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.
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.
The weight of the load is transferred to the ground via the landing pad.
Compressed air is applied; the air caster’s membrane lifts the load from the ground.
Air pressure overcomes the load’s weight; a controlled leakage creates an air film and it floats.
