Suitable for heavy duty, demanding applications requiring:

• Low leakage rates.
• Suitability for high airflow velocities.
• Minimal resistance to airflow.
• Large single section sizes.

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.
