How It Works
While air casters provide powerful solutions, they actually operate under fairly simple principles.
How Air Casters Work
An air caster is a pneumatic device which forms a lubricating film of air between the load and floor surface, similar to that of a hovercraft or an air hockey table. A flexible, wear-resistant urethane diaphragm is inflated by compressed air, forming a seal with the floor and lifting the structure off its rest pads. Air is then squeezed between the floor and the diaphragm, creating a thin film of air and allowing the load to float.
On a smooth floor, this air film allows for nearly friction free movement in any direction. With an excellent floor, the volume of air required can be very low, which results in a very efficient operation. When floating on air casters, a 1000-lb. load can be moved with about 1 pound of force – that’s 10 times better than conventional wheels or casters.
Airfloat air casters are constructed of a smooth-textured, completely homogeneous material. When pressured the air caster will stretch uniformly and closely follow the contours of the floor, maintaining a consistent air film. This is evident with lower drag forces and less air consumption than that produced by fabric-reinforced air casters used by some Airfloat competitors.
