2530 Motorised Fire Damper
The Advanced Air 2530 Motorised Fire Damper is designed to meet the requirements of dynamic fire testing, offering low leakage at ambient and high temperatures during the fire test. Its main purpose is to close on alarm activation and to stay closed, maintaining the integrity of the fire-rated barrier and stopping the spread of fire, cold, and hot smoke, including toxic fumes.
The 2530 incorporates a blade profile of aerodynamic double skin construction with a metal-to-metal seal, interlocking opposed operation, achieving low leakage for smoke performance as stipulated in BS EN1366-2 with a classification of two hours in both horizontal and vertical installations.
The 2530 includes a unique and versatile jackshaft arrangement with an electrical thermal fuse rated at 74 °C. When reached the actuator power is disengaged, the actuator closes the blades within 15 seconds. The blades are then held in the closed position by the knee-lock mechanism, therefore not relying on the actuator to hold the blades closed. When actuator power is restored, the damper opens within 90 seconds. The 2530 Motorised Fire Damper is available with spigotted connections.
Various tested installation options are available and are detailed in our Installation, Operation and Maintenance manual. This product is both flexible and versatile and can be modified to meet most special requirements on size and installation.
Advanced Air also offers training on how to install the products correctly within our in-house training facility. Installation Training
