NCA S800B • Heavy duty volume control damper
- S800B heavy duty volume control dampers are cost effective and robust units
- Galvanised steel frame and blades
Application
- Suitability for high airflow velocities is provided by the robust construction utilising a 180mm deep galvanised steel frame, roll formed 1.5mm thick galvanised steel triple v blade and steel drive system.
- Minimal resistance to airflow is another benefit of the large format design, with the 150mm blade pitch giving a maximum free area of around 80%.
- Large single section sizes are possible thanks to the low torque characteristics of the drive system, meaning single sections of up to 1.2m x 2m can be manufactured and driven from a single actuator.
Material
- Galvanised steel frame and blades
- Zinc plated steel drive system components
- Optional seals from silicone rubber and stainless steel
Mounting
- Flanged Mounting to ducts.
- Weight: Approx 30Kg/M2
