Manual balancing dampers

Manual balancing dampers are used to manually adjust air flow, preferably in ductwork. The damper has aero foil blades on multi bladed dampers, and single blade on circular dampers up to Ø 400mm.

Multi bladed dampers have opposed blade action to give even flow across the duct face when in a partially closed position. Manual balancing dampers can be delivered with integrated measuring stations to monitor and control air flow in duct systems.
