4.1WIB6 – 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.

Metal Welded Inertia Bases, 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:

Provide vibration isolation and stabilize 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:

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.

Benefits:

Reduced Noise: Combining an inertia base with vibration isolation can significantly reduce noise generated by vibrations, improving the working environment.

Equipment Longevity: The reduction in transmitted vibrations can extend the lifespan of machinery and equipment by minimizing wear and tear.

Structural Protection: It protects the integrity of the surrounding structures by preventing vibrations from causing damage.

Comfort: Inertia bases and vibration isolation techniques can enhance comfort for building occupants by minimizing perceptible vibrations.

Considerations:

Design and Engineering: Proper design, including mass calculation, vibration analysis, and selection of appropriate vibration isolation components, are essential for an effective solution.

Installation: Correct installation of the inertia base and vibration isolation components is crucial for achieving the desired results.

Inertia base with the combination of vibration isolators offers a comprehensive approach to controlling vibrations generated by machinery and equipment. Installing inertia base helps to minimize the transmission of vibration, reduce the risk of equipment failure, structural damages.
