Christie & Grey offer specialist HVAC vibration isolation solutions for fans and air handling units in industrial and building services settings.

Our isolation mounts and spring systems are designed to control vibration at the source, protect supporting structures, and help maintain quieter, more comfortable internal spaces.

Fans and AHUs generate vibration through rotating components, airflow turbulence, and varying operating loads. Without effective isolation, this vibration may be transferred into floors, ductwork, and building structures, causing rumbling, drumming, and structure-borne noise within buildings. Christie & Grey solutions are designed to address these issues directly, supporting plant performance and maintaining structural integrity over the long term.

Our products include a wide range of anti-vibration fan mounts, including axial and centrifugal fan isolators, combined rubber-and-spring systems, and customised anti-vibration fan mounts selected to suit speed, load, and installation conditions. Each system is designed to provide effective vibration isolation and maintain stable, efficient plant operation.

Proven anti-vibration expertise

Christie and Grey provide vibration isolation systems for a wide range of industrial and mechanical plant applications, alongside fans and air handling equipment, where vibration and transmitted noise control are critical. Many industrial facilities contain multiple rotating machines operating in close proximity, making coordinated isolation across interconnected systems essential. Additional applications within our product range include pumps, compressors, power generation equipment, and other continuously operating plant. Each category has distinct load and frequency characteristics, and we work closely with clients to ensure the correct isolation mounts are applied consistently, supporting durability, safety, and long-term structural performance.

Frequently Asked Questions

How does Christie & Grey address centrifugal fan vibration issues?

Centrifugal fan vibration is controlled through correctly selected isolation systems based on operating speed, load distribution, and installation conditions, helping stabilise equipment during long-term operation.

How does vibration isolation benefit HVAC and building services equipment?

Effective isolation reduces noise transmission through the structure, limits mechanical stress on supporting elements, and supports stable, long-term operation of continuously operating HVAC plant.

What role do fan vibration isolators play in HVAC installations?

Fan vibration isolators reduce the transmission of vibration from equipment into floors, frames, and connected services, supporting low-noise operation and maintaining mechanical integrity of both plant and structure.

Which type of isolation system is suitable for air handling units?

AHU isolation systems may be rubber-based, spring-based, or hybrid solutions, depending on unit mass, operating frequency, and structural interaction. Selection is based on engineering assessment of load and vibration requirements.

Why do fans and air handling units require vibration isolation?

Fans and AHUs generate vibration from rotating components and airflow forces, which may be transmitted into structures without effective isolation. Proper isolation helps limit vibration transfer and protects connected steelwork and ducting
