Capabilities
Bespoke Vibration Isolation Excellence
WITT UK Group’s anti vibration mounts represent decades of refinement in vibration control technology, uniquely developed to address the demanding requirements of industrial fan installations. Our comprehensive range accommodates loads from 50kg to 50,000kg, with natural frequencies from 3Hz to 25Hz, ensuring optimal isolation for every application. From precision laboratory environments requiring vibration levels below 0.1mm/s to heavy industrial installations managing multi-tonne fans, our mounts deliver exceptional isolation performance whilst maintaining structural integrity. Each mount design undergoes rigorous testing for compression, shear, and tension loads, with fatigue testing exceeding 10 million cycles—ensuring decades of reliable service in the most demanding environments. Our Yorkshire facility manufactures mounts using premium materials including natural rubber compounds, neoprene for oil resistance, and specialised elastomers for extreme temperatures, with metal components in galvanised steel, stainless steel, or marine-grade materials.
Engineering Precision for Critical Applications
Our anti vibration mounts go beyond simple isolation, providing precise equipment positioning, thermal expansion accommodation, and seismic restraint capabilities. The unique multi-directional stiffness characteristics enable optimised performance for vertical loads whilst managing horizontal forces from belt tension, wind loads, or seismic events. We offer spring mounts for low-frequency isolation below 3Hz, rubber-in-shear designs for medium frequencies, and constrained-layer mounts for high-frequency attenuation. Special variants include failsafe designs with integral snubbers, height-adjustable mounts for precise alignment, and captive designs preventing mount separation under extreme conditions. Whether isolating a rooftop air handling unit from a hospital ward below, preventing fan vibration transmission in a recording studio, or managing seismic loads in nuclear facilities, our mounts deliver measured performance improvements typically achieving 95-99% vibration reduction.

Frequently
Asked Questions
Why are anti vibration mounts essential for industrial fans?
Industrial fans generate significant vibration from rotating masses, aerodynamic forces, and drive system dynamics. Without proper isolation, these vibrations transmit through building structures causing noise complaints, equipment damage, structural fatigue, and precision equipment interference. Our mounts prevent transmission of vibration frequencies above their natural frequency, typically achieving 95-99% isolation efficiency. This protects building structures, eliminates noise complaints, prevents equipment misalignment, and ensures compliance with workplace vibration regulations including Control of Vibration at Work Regulations 2005.
How do I select the correct anti vibration mount?
Mount selection requires careful consideration of multiple factors: equipment weight including operating fluids and attached components, operating speed determining forcing frequencies, required isolation efficiency based on sensitive receptors, environmental conditions including temperature and chemical exposure, and structural constraints including available space and mounting points. Our engineers calculate natural frequency requirements ensuring mounts operate in their isolation range—typically 3-4 times below forcing frequency. We provide detailed selection charts and engineering support, ensuring optimal mount specification for your specific application.
What's the difference between spring and rubber mounts?
Spring mounts provide low natural frequencies (1.5-5Hz) ideal for low-speed equipment or sensitive environments, offering consistent stiffness over wide temperature ranges and virtually unlimited life without degradation. However, they lack inherent damping and may transmit high-frequency noise. Rubber mounts offer natural frequencies from 5-25Hz with excellent damping characteristics, reducing resonant amplification and high-frequency transmission. They’re more compact and cost-effective but may degrade over time in harsh environments. Many installations benefit from combination systems using springs for primary isolation with rubber elements for damping.
How do anti vibration mounts handle seismic loads?
Seismic-rated mounts incorporate special features managing earthquake forces whilst maintaining vibration isolation. Designs include integral snubbers limiting movement during seismic events, all-directional restraint preventing equipment walking or overturning, and increased lateral stiffness managing horizontal accelerations. Mounts are qualified to relevant standards including IEEE 344 for nuclear applications and Eurocode 8 for general construction. Testing includes shake table verification demonstrating structural integrity and post-seismic functionality. Our seismic mounts protect critical equipment in hospitals, data centres, and emergency facilities across earthquake-prone regions.
What maintenance do anti vibration mounts require?
Quality mounts require minimal maintenance, but regular inspection ensures continued performance. Visual checks should identify rubber cracking or deterioration, oil contamination affecting rubber properties, corrosion on metal components, and unusual settling indicating overload or failure. Spring mounts need periodic inspection for corrosion and coil contact, whilst rubber mounts should be checked for hardening or softening indicating ageing. Most installations require annual inspection with detailed checks every five years. Our mounts’ exceptional durability means replacement typically coincides with equipment replacement after 25-30 years, though many installations exceed 50 years’ service.
Can anti vibration mounts improve energy efficiency?
Yes, proper vibration isolation significantly improves system efficiency. Reduced vibration decreases bearing wear and misalignment, maintaining optimal fan efficiency throughout service life. Elimination of structure-borne vibration prevents energy loss through building elements. Stable mounting maintains belt tension and alignment, preventing slip and power loss. Variable-speed drives operate more efficiently without vibration-induced harmonics. Studies demonstrate properly isolated fans maintain 5-10% better efficiency over their service life, with reduced maintenance requirements providing additional operational savings. The initial mount investment typically returns through energy savings within 2-3 years.
