On a standard air bearing system using regular A-type air bearings the required minimum air pressure from the shop supply should be 70 psi.
On air bearing systems using B-type air bearings the minimum required air pressure from the shop supply should be 70 psi.
The volume of air required will differ depending on the floor surface, the weight of the load, and the type of bearing being used. All air requirements will be explained to you at the time of order.
