PRD Pressure Relief Damper

ASLI Pressure Relied Dampers (PRD) are designed to maintain certain amount of pressure in a pressurized zone (staircase, operation theatre, etc). The amount of pressure maintained in the pressurized zone is adjustable by the counterweight on the PRD.

Designed to automatically relieve excess air pressure in duct systems.
Spring-loaded or counterweight blades open when pressure exceeds set value.
Prevents damage to ductwork and equipment from over-pressurization.
Provides low resistance to airflow during normal operation.
Can be factory-calibrated to specific pressure settings.
Suitable for both supply and exhaust air applications.
Compact, lightweight, and easy to install.
