S900B - Volume control damper, Circular Spigotted
General-purpose volume control and shut-off dampers.
Slimline units intended for low/ medium velocity applications.
General-purpose volume control and shut-off dampers intended for low/medium velocity applications. Utilizing the HVC standard out-of-airstream linkage, all gears are protected from dust and dirt by being positioned within the channel outer frame, making S900 dampers less susceptible to requiring frequent maintenance than rival units where the linkage is within the airstream.
Series 900 dampers are multi-leaf, opposed blade dampers available in two configurations:
S900B: Standard volume control dampers, designed for balancing applications where a high level of shut-off is not required - Galvanized steel throughout as standard, stainless steel optional.
S900C: Shut-off dampers; fitted with additional seals, shut-off dampers have far lower leakage levels than standard VCDs - Galvanized steel frame and case as standard, stainless steel optional, blades are aluminium with a silicone rubber tip seal.
