Circular Spigotted
Heavy-duty shut-off dampers for demanding applications.
Application
Suitable for heavy duty, demanding applications requiring:
- Low leakage rates.
- Suitability for high airflow velocities.
- Minimal resistance to airflow.
- Large single section sizes.
Description
Designed to satisfy the most demanding applications, the S800C heavy duty shut-off damper is a robust, low leakage unit.
Features and benefits:
- Low leakage rates are assured by the fully sealed design, making use of silicone rubber blade edge seals, stainless steel side seals and EPDM rubber stop gap seals.
- Heavy duty design for high velocity applications.
- Aerodynamic extruded aluminium aerofoil blades for minimal pressure loss when open.
- Large single section sizes are possible thanks to the low torque characteristics of the drive system. Single units available up to 2 x 2 m, driven from a single actuator.
- Square, circular and flat oval connections for all types of ductwork.
- Variety of control options including comprehensive range of actuators.
