Keeping Everything Flowing in the Right Direction

Non Return Damper (NRD)

Our range of high integrity non-return dampers have been designed for use in the offshore oil & gas and nuclear markets where corrosion resistance, mechanical integrity and performance are of utmost importance.

They are used to prevent backflow and relieve pressure through ventilation and duct systems and include the following design features:

  • Continuously welded construction
  • Parallel blade motion
  • Excellent corrosion resistance
