Figure 5-1 Freestanding Foot-Mounting Arrangement
The compressor can be bolted to a firm, level foundation that is strong enough to support its weight
such as a concrete floor or alternatively secured to a vehicle chassis or tray for mobile applications.
Flexible vibration isolators must be used between the compressor and mounting surface. Do not bolt
uneven feet tightly to the foundation as this will cause excessive stress on the air receiver tank. Use
metal shims to pack under any “short” feet, if necessary, which is most often due to the floor surface
not being perfectly level rather than the mounting feet being uneven. There are three common
methods used for such bolted-down, foot-mounting installations:
(a) The basic method as shown in Figure 5-2 has the compressor being bolted-down loosely
through the factory supplied vibration isolators with a gap of 1 to 3 mm to allow for vertical
movement. One should apply thread lock adhesive such as Loctite® or use a nylon insert lock
nut to prevent the central fastener from unscrewing.

(b) A preferred method as shown in Figure 5-3 is for the compressor set to be bolted-down
loosely through the factory supplied compression and rebound vibration isolators with a gap
of 1 to 3 mm to allow for vertical movement. One should apply thread lock adhesive such as
Loctite® or use a nylon insert lock nut to prevent the central fastener from unscrewing.
