Pressure differential system dampers SRC

Intended Use:

SRC multi-blade dampers with opposed blades are designed for air flow adjustment or shutting off in rectangular ventilation ducts.

SRC multi-blade dampers with opposed blades are designed for air flow adjustment or shutting off in rectangular ventilation ducts. They can be installed outside buildings, because the actuator and the damper mechanism is protected from direct impact of weather factors. The design of the damper ensures class 3÷4 integrity rating according to EN-1751. Special sealing inserts installed at the blade ends ensure high integrity. The respective blades are driven by an actuator, through a system of tie rods and gear reducer in backward arrangement.

Operating temperature: from -20°C to +50°C.


The housing of the SRC damper is made of galvanised steel sheet. RAL painting of the body is also available to special order. The damper blades are made of aluminium profiles. Special inserts with a sleeve seal are installed at the ends of the blades. The blades are provided with plain bearings made of fibreglassreinforced PP.

In terms of external appearance, the actuator and the damper mechanism are installed in a box providing protection against direct impact of weather factors.
