Mounting Options

Vibration Isolators

Base-mounted neoprene or spring isolators are available to lessen mechanical vibration and assure quiet operation. Free-standing, restrained and housed spring isolators are also available. Isolators are sized to match the weight of each fan.

Free-Standing Open

Spring Mounts -

Type 3, 1-inch Deflection Free-standing spring isolators are unhoused laterally stable steel springs. They provide a minimum horizontal stiffness of 0.8 times the rated vertical

stiffness and provide an additional 50% overload capacity. These isolators are equipped with a top-mounted adjusting bolt and an acoustical non-skid base. Springs are color coded to indicate load capacity.

Housed Spring Mounts

Type 4B, 1-inch Deflection Housed spring isolators consist of steel springs assembled into a telescoping housing with a top-mounted adjusting bolt and an acoustical non-skid base. Housed spring isolators

include resilient inserts to prevent metal-to-metal contact and provide snubbing for side loads. Springs provide an additional 50% overload capacity and are color coded to indicate load capacity.

Rubber Mounts -

Type 2, ¼-inch and

½-inch Deflection Neoprene mountings consist of a steel top plate and base plate completely embedded in colored (oil- resistant) neoprene for easy

identification of capacity. Neoprene mountings are furnished with a tapped hole in the center. This enables the equipment to be bolted securely to the rubber mount.

Restrained Spring

Mounts -

Type 4A, 1-inch Deflection Restrained spring isolators consist of laterally stable, free-standing springs assembled into a steel housing. These assemblies

are designed for vertical and horizontal motion restraint. Restrained spring isolators can be used for blocking during equipment installation and are provided with leveling bolts. Springs provide 50% overload capacity and are color coded or identified to indicate load capacity. Restrained spring mounts are recommended for equipment subject to wind loading or large torquing forces.

Direct Mount - Type A

No base required. Isolators are attached directly to equipment. Direct isolation can be used if equipment is unitary and rigid without the use of additional support. If there is

any doubt whether or not equipment can be supported directly on isolators,

use rails, bases or consult the factory.

Equipment Supports

Models GESS and GESR equipment supports are available for roof mounting of utility fans up to size 36. Equipment supports are available in a number of lengths, widths, heights, and can also be built for a pitched roof.

Mounting Rails

with Isolators Isolation mounting rails are available with either rubber mount, free-standing open or restrained spring isolators. The isolators are mounted between aluminum rails that run the length of the

fan base. Isolation rails provide easy installation on isolated systems,

and are ideal for applications where

there is a large overhung load. Mounting rails are available for fans up to size 36.
