5.1WIB6 – Welded Inertia Base

WIB6 - Heavy-duty Welded Inertia Bases are commonly used in the industry:

  • to reduce the amplitude of mechanical vibrations.

  • lower the center of gravity.

  • lessen the equipment’s movement during operations.

WIB6, when filled with concrete and supported by Vibrasystems’ spring mounts, provides excellent vibration isolation.

WIB6 - Welded Inertia Bases are designed according to ASHRAE guidelines. Made from structural steel C Channels and reinforced with welded steel square bars each WIB6 has welded brackets to install spring mounts under them. Welded Inertia Bases are finished with a rustproof primer and a topcoat paint. 

Recommended for:

HVAC equipment such as air compressors, vacuum pumps, close-coupled pumps, inline pumps, end suction pumps, double suction pumps, package pump systems, axial fans, plenum fans, centrifugal fans, engine-driven generators, packaged Air Handler Unit, packaged Air Conditioner Unit, industrial centrifuges, etc.

Features:
Features:
Welded-in reinforcing bars provide rigidity to the welded structural steel perimeter frame.
Rustproof Primer + topcoat paint provide good corrosion resistance.
Templates with anchor bolts are optional.
Seismic Restrained Spring Mounts are supplied with the WIB6 - Inertia Base and available in 1” & 2” deflection springs.
Recommendations:
Inertia Base’s height must be a minimum of 1/10 of the longest span between spring isolators, but not less than 6”.
Inertia Base’s weight (frame + concrete) should be 2 times the total installed equipment’s weight.
Concrete minimum 3,000 psi strength and density of 150 lb/cub. ft (concrete by others).
After WIB6’s installation is complete, the frame should have a minimum operating clearance of 1” to the floor.
