Pressure Relief Damper

ICEMAC Pressure Relief Damper (IC-PRD Series)

Product Overview
The ICEMAC IC-PRD Series is a mechanically actuated pressure relief damper designed to automatically discharge excess air pressure in ventilation systems. When internal duct pressure exceeds a pre-set limit, the damper’s spring-loaded blades open to release the pressure, protecting equipment and maintaining system integrity. The IC-PRD operates passively—without external control or power—making it ideal for critical applications requiring reliable, fail-safe pressure stabilization.

Key Features

• Spring-Loaded Design – Opens automatically under excess pressure; no power or sensors required.

• Robust Construction – High-strength galvanized steel casing and bronze-blade bearings ensure long-term durability.

• Maintenance-Free Operation – Factory-set opening pressure eliminates the need for recalibration.

• Flexible Installation – Can be installed in horizontal or vertical orientation with flange mounting.

Applications

• AHU Discharge Zones – Protects downstream ducting and fans from startup surges or blockage pressure.

• Pressurized Escape Routes – Maintains safe door operation in stairwells by venting overpressure.

• Smoke & Fire Ventilation Systems – Relieves transient pressure during smoke evacuation.

• Cleanrooms & Labs – Supports duct protection and airflow stability in sensitive environments.

Advantages

• Reliable Overpressure Protection – Instantaneous relief during pressure spikes.

• Versatile Integration – Compatible with new builds or retrofit ventilation systems.

• Corrosion-Resistant Finish – Custom RAL color coatings available upon request.

• Low-Cost Safety Assurance – Eliminates the need for complex sensors or BMS integration.
