How to evaluate the suitability of an isolator?

walraven vibratek how to redt the tables

How to read the tables?

Example: the load per one vibro-isolator is 280 kg, and the operating frequency of the device is 2300 rpm. See the 5 steps to read from the table (as shown in the attached diagram) to find out if the selected vibro-isolator meets the damping conditions and is well-matched.

The motor’s speed (rpm) causes vibrations (Hz) in HVAC devices. To simplify product selection, we’ve organized tables by speed, as it’s easily obtainable from suppliers.

  1. Select the weight of the device in the table – greater than or equal to 280 kg
  2. Horizontally to the left, you can see the product number of Walraven VibraTek®
  3. Horizontally to the right, you can read the deflection
  4. Locate the column with a frequency lower than 2300 rpm
  5. Read the damping performance at: cross-deflection and frequency
