Please Note: The hose sizes shown in the chart are the absolute minimum you should use. If a lesser hose size is used, the system may not operate correctly and could cause problems with the air bearings. Such problems could cause damage to the air bearings for which Hovair Systems will not be responsible. Replacement charges will apply. Using a slightly higher size hose will not affect the operation of your system.

Please note: A load module includes all elements including weldment, air bearing, valve and load pad.
