High Performance/Aluminium

General:

The VDA Series Aluminium Volume Control Dampers provide highly efficient airflow control in air handling systems. The VDA is a standard low leakage damper, available with ultra-low leakage feature (optional) and parallel or opposed blade configuration.

The damper frame, blades and linkages are made of aluminium and guarantee long life with minimum maintenance. Interlocking blades for reduced (LOW) leakage. Specially formed standard components and non-corrosive bearings conform to the specifications required for high quality, low leakage, maximum rigidity and low operating torque. This allows the use of smaller or fewer actuators.

Multiple sections are interconnected with a solid drive shaft and provide, together with individually adjustable internal blade linkages, a positive connection for optimum close-off sealing.

Total damper design and close manufacturing tolerances of Blendair dampers result in LONG DAMPER LIFE, SMOOTH & RELIABLE CONTROL and ENERGY SAVING.

Low/Ultra-Low Leakage

General:

The VDL and VDU Series Volume Control Dampers provide highly efficient airflow control in conventional air handling systems. VDL is a standard low leakage damper and the VDU is the ultra-low leakage damper and the VDU is the ultra-low leakage version damper. Both damper types are available with parallel blade configuration for variable air volume application and opposed blades ofr air mixing application.

Interlocking blade edges and spring steel side seals provide the basis for reduced (LOW) Leakage – the ULTRA LOW leakage version is fitted with re-enforced inflatable balloon seals. Specially formed standard componenets and non-corrosive bearings conform to specifications required for high quality, low leakage, maximum rigidity and low operating torque. This allows the use of smaller or fewer actuators.

Multiple sections are inter-connected with a solid drive shaft and provide, together with individually adjustable internal blade linkages, a positive connection for optimum close-off sealing.

Total damper design and close manufacturing tolerances of Blendair dampers result in LONG DAMPER LIFE, SMOOTH & RELIABLE CONTROL and ENERGY SAVING.
