Understanding Pressure Relief Vents

How They Work

Pressure relief vents are engineered to activate during the discharge of gas suppression agents such as FM200, IG541, or Novec 1230.


These systems create a rapid change in pressure, and without proper venting, the pressure build-up could lead to damage or even failure of the enclosure. Fire-rated pressure relief vents are designed to open automatically when pressure levels exceed a certain threshold, maintaining the balance and ensuring that the fire suppression agent can fill the space effectively to extinguish the fire.

Benefits of Fire-Rated Pressure Relief Vents

One of the primary benefits of fire-rated pressure relief vents is their dual functionality—they provide both pressure management and fire resistance. This means that in addition to protecting the enclosure from over-pressurisation, they also help to maintain fire safety standards by preventing fire spread through the vent. The design ensures that these vents seal tightly after discharge, maintaining the integrity of the room and ensuring compliance with safety regulations. This combination of protection and efficiency makes pressure relief vents an essential part of any advanced fire suppression system.

By integrating pressure relief vents into your gas suppression system, you ensure that the fire protection process is smooth, effective, and safe, safeguarding both your facility and its occupants.
