Motorised Circular Damper with Spring Return

Spring-return actuator for dampers in ventilation and air-conditioning systems

This damper features an adjustable blade position that has been designed specifically for installations where space is at a premium and installation within the fire separation is not feasible.

Works to provide greater free area than comparable-sized conventional multi-blade fire/smoke dampers.

This Fire and Smoke damper has the flexibility of being a volume control damper with the facility that allows air balance and the setting of the damper blade position during system commissioning via the fitted actuator.
