Protection
Protects rooms and structures from damaging pressure changes during the discharge of gaseous fire suppression systems.
Products / Pressure Relief
Pressure Relief Dampers
For gaseous fire suppression systems, marine installations and critical infrastructure.
Why Is Pressure Relief Necessary?
The discharge of Inergen, Novec, Argonite, nitrogen or CO₂ can create rapid pressure changes in enclosed spaces. Without properly designed pressure relief, these pressure changes can cause damage to walls, doors, ceilings and critical equipment.
Our pressure relief dampers provide controlled pressure relief, protecting rooms, structures and equipment from damaging pressure changes.

Positive and Negative Pressure Relief Dampers
Custom Pressure Relief Dampers
For Novec, Inergen and Other Gaseous Fire Suppression Systems
Gaseous fire suppression systems such as Inergen, Argonite, Novec 1230, CO₂ and nitrogen can create rapid pressure changes in enclosed spaces. Without controlled pressure relief, these pressure changes can cause damage to the building structure and critical equipment.
Pressure relief dampers from Puma Fire Products are designed to relieve positive and negative pressure in a controlled and efficient manner.
Novec dampers manage both positive and negative pressure. Inergen dampers are designed for controlled positive pressure venting. All models can be combined with active venting of the extinguishing gas after system discharge.
All dampers are independently tested and certified in accordance with leading international fire safety and performance standards.
