Kinetics RH-AD is a neoprene vibration isolation hanger for suspended light mechanical equipment, piping and ductwork. It uses a colour-coded, oil-resistant elastomer-in-shear element inside a steel hanger bracket with a stamped load-transfer cap. Four models provide rated loads from 30 to 125 lb, each with a published rated deflection of 0.30 in. Kinetics Group supports HVAC, MEP and acoustic projects across the UAE, GCC, Middle East and MENA region.
Engineered for Performance.
Kinetics Model RH-AD is a neoprene vibration isolation hanger designed to reduce vibration and noise transmission from suspended light mechanical equipment, piping and ductwork. It is intended for suspended sources of audible-frequency vibration and for the isolation of noise in piping and ductwork systems.
The RH-AD combines a colour-coded, oil-resistant elastomer-in-shear insert with a stamped load-transfer cap and steel hanger bracket. It provides a compact vibration-control solution for HVAC, MEP and building-services projects across the UAE, GCC, Middle East and MENA region.
What Is an RH-AD Neoprene Vibration Isolation Hanger?
The RH-AD creates a resilient separation between a suspended mechanical service and its supporting structure. The neoprene element is loaded primarily in shear rather than simple compression, increasing allowable strain without accelerating deterioration.
The steel bracket surrounds the isolation element while the stamped load-transfer cap distributes the applied suspension load. The arrangement helps reduce the rigid transmission path through which vibration and noise can enter the building structure.
RH-AD Applications
RH-AD Models, Rated Loads and Deflection
| Model | Rated Load | Approximate Metric Load | Elastomer Colour | Published Rated Deflection |
|---|---|---|---|---|
| RH-30AD | 30 lb | 13.6 kg | Silver | 0.30 in. / 7.6 mm |
| RH-45AD | 45 lb | 20.4 kg | Red | 0.30 in. / 7.6 mm |
| RH-75AD | 75 lb | 34.0 kg | Green | 0.30 in. / 7.6 mm |
| RH-125AD | 125 lb | 56.7 kg | White | 0.30 in. / 7.6 mm |
Selection requirement: Select each RH-AD model according to the actual operating load imposed at that individual suspension point. Do not select all hangers from total equipment weight alone because weight distribution between suspension points may be unequal.
The published rated loads are maximum continuous operating loads. Final model selection must be confirmed against the approved vibration-isolation submittal and actual supported load.

Refer to the official RH-AD dimensional drawing for the location and meaning of each dimensional reference. Suspension rods and associated hardware are supplied by others.
How the RH-AD Reduces Vibration Transmission
Suspended equipment, ductwork and piping can transmit vibration through steel rods and supports into slabs, beams and other building elements. The RH-AD neoprene element introduces a resilient connection at the suspension point.
Loading the elastomer in shear permits controlled movement while supporting the suspended service. The hanger bracket also permits support-rod misalignment through a 30° arc without unintended metal-to-metal contact that could bypass the isolation element.
RH-AD or Spring Vibration Isolation Hanger?
RH-AD is intended for suspended sources of audible-frequency vibration and noise in piping and ductwork. Applications requiring greater static deflection or lower-frequency vibration isolation may require a spring-based hanger.
For combined spring and neoprene isolation, review the SRH Spring-Neoprene Vibration Isolation Hanger. For spring isolation, review the SH Spring Vibration Isolation Hanger.

Technical Documentation
RH-AD Technical Support in the UAE and MENA
Kinetics Group supports acoustic consultants, MEP consultants, HVAC contractors, developers, procurement teams and facility managers across the UAE, GCC, Middle East and MENA region.
For RH-AD selection, provide the equipment or service description, operating weight at each hanger point, suspension arrangement, rod size, project location and specified vibration-isolation requirements.
Contact Kinetics Group for RH-AD product selection, technical submittals and project enquiries.
RH-AD is used to reduce vibration and noise transmission from suspended light mechanical equipment, piping and ductwork. It is intended principally for suspended sources of audible-frequency vibration and piping or ductwork noise.
The available models have rated loads of 30, 45, 75 and 125 lb, equivalent to approximately 13.6, 20.4, 34.0 and 56.7 kg.
Each RH-AD model in the published product table has a rated deflection of 0.30 in., equivalent to approximately 7.6 mm.
Select the model according to the actual operating load carried by each individual hanger point. Confirm the selection against the approved project submittal rather than using total equipment weight alone.
Yes. The hanger bracket is designed to permit support-rod misalignment through a 30° arc without metal-to-metal contact or another isolation short circuit.
The RH installation drawing contains a seismic installation detail involving structural clearance and an additional washer and nut below the hanger box. Final seismic suitability and installation must be confirmed by the project engineer and approved seismic submittal.
A spring or spring-neoprene hanger may be more appropriate when the application requires greater static deflection or lower-frequency vibration isolation than a neoprene hanger provides.
RH-AD Installation Requirements
The appearance of the neoprene element may vary from the illustration. Installation must follow the approved project submittal and the official Kinetics installation instructions.
Seismic Installation Detail
The RH installation drawing includes a separate detail for seismic applications. That detail calls for approximately 1/8 in. clearance between the hanger box and building structure, together with an additional washer and nut below the hanger box. The washer outside diameter must be larger than the rod opening in the bottom of the box.
When the system is at operating weight, the lower nut is adjusted until the washer is approximately 1/4 in. below the bottom of the hanger box. Final seismic suitability, restraint design and installation must follow the approved seismic submittal and project engineer’s requirements.
