MPV Pressure Vents

The world leading pressure vents with 4 hour fire resistance


Whether Inert Gas agents like Argonite or Inergen the MPV range will vent the pressure caused by a system discharge.

By removing one screw set when installing the MPV, it becomes a two way Negative and Positive pressure vent for agents.

With 4 hour fire resistance and 80 Pascal operation this is a true market leader.
