Robust volume control dampers for large scale balancing applications.
The new NCA S800B heavy duty volume control damper has been designed to suit applications requiring a large format volume control damper for balancing or throttling applications, without the requirement of verified low leakage levels when fully closed.
The robust construction comprises a 1.2mm galvanised steel frame, 1.5mm thick roll formed 'triple-v' blade/s and an all steel low torque drive system, ensuring smooth operation.
Although untested for blade leakage when closed, S800B dampers are available with silicone rubber blade edge seals and/or stainless steel frame side seals if required. Should verified levels of blade leakage be required, we would recommend NCA S800C heavy duty shut-off dampers.
Like all dampers available from HVC, the drive system is protected from dust and dirt by being positioned within the channel outer frame, making S800B dampers less susceptible to requiring frequent maintenance than rival units where the linkage is within the airstream.
A range of control options are available for your S800B dampers, from locking quadrants to factory fitted electronic or pneumatic actuators. ATEX rated actuators can be supplied if required.
