Sound Suppressor

The in-line Suppressor is a bi-directional device that reduces noise, shock, and vibration. The suppressor consists of three concentric, cylindrical metal noise baffles or diffusers inside a nitrogen-charged tubular rubber bladder. The suppressor reduces hydraulic noise by up to 60%, pulsations by up to 90%, shock by up to 90%. It stops the noise before it increases as it travels through the piping and radiates off other structural components.

  • Comes in all pipe sizes - from 3/8" N.P.T. to 2" N.P.T., and all tube sizes - from .375" to 2.0". Flange connections are available for large sizes.
  • 3000 psi or 5000 psi
  • Easy to size and install
  • No engineering required
  • Inexpensive and Compact
  • Helps to meet OSHA noise standards
  • Bi-directional part. Suppressor does not need to be assembled in a certain direction.
