Serie VSR1 — Isolateur au plancher sismique

Floor isolators

VSR1 Series – Seismic Floor Isolator

Name: VSR1 Series – Seismic Floor Isolator
Brand: Deflection

Spring seismic floor isolator, VSR1 configuration.

Deflection VSR1 Series isolators: reliable isolation

Deflection VSR1 Series isolators are designed to reduce vibration from industrial equipment. Built from solid coated steel, they include a leveling device and non-skid pads for a stable installation. With a load capacity of 200 to 2,800 lb and a 2 in deflection, they suit compressors, fans, pumps, chillers, cooling towers and other HVAC equipment.

Frequently asked questions

What is the VSR1 Series isolator?

A seismic spring floor isolator for floor-mounted mechanical equipment, providing vibration isolation and restraint during an earthquake.

What is the difference between the VSR and SM families?

Both families do the same job (isolation plus seismic restraint), with different housing designs and load ranges. The PDF technical sheets let you compare for your equipment.

What equipment is the VSR1 used for?

Compressors, pumps, fans, chillers and other floor-mounted HVAC equipment in seismic zones.

How do I choose between VSR1 and VSR2?

By the load per isolator and the dimensions required. See both technical sheets or ask for a recommendation.
