Blast Suppression Dampers

Protection against instantaneous pressure changes due to an explosion.

A blast suppression damper is designed to protect against instantaneous pressure changes due to an explosion. The HBS series is constructed with a heavy-duty double-flanged channel frame and double thickness fabricated airfoil blades. Blast suppression dampers can be used in the following applications:

Government buildings
Mining, gas, and oil platforms
Refineries
Protection of ventilation systems

HBS-330

Protects against blasts and rapid pressure changes by closing damper blades in the same direction as normal airflow.
