The RVD Series provides effective vibration control for use directly under HVAC, power generation  and electrical equipment in conjunction with the equipment's mounting holes.

The RVD Series have  a steel baseplate with mounting holes and a threaded insert at the top of the isolator for attaching to equipment. All metal parts are completely embedded in the elastomeric material.

The RVD Series offer deflections to 0.50". Three different sizes offer a load capacity range of 45 to 2,400 lbs. per isolator - offering isolators that may be accurately selected for the equipment weight. 

Features & Benefits

  • Static load range of 45 - 2,400 lbs. offers solutions for a wide range of equipment weights

  • Ribbed isolator base provides a non-skid surface


  • Air handling units
  • Fans
  • Pumps
  • Chillers
  • Air compressors
  • HVAC equipment
  • Power generation
  • Electrical transformers




The engineers we employ hold the highest industry-recognized credentials in structural analysis, elastomer development and system dynamics.


We are the first ISO accredited PCA ISO-17065, third-party certification body for special seismic certification of non-structural building components and their mounting configurations by the ICC’s International Accreditation Service.

Test & Measurement

We are the only ISO 17025:2005 Accredited Seismic Simulation Test Laboratory with a triaxial shake table owned and operated by California licensed Structural engineers.
