APS dampers are constructed with an aluminium frame and aerofoil blades. The 50 mm pitch of the blades allows a much wider range of damper height to ensure versatile duct designs. The top and bottom frames incorporate a dip seal to eliminate dirt built up that normally  occurs on fence seals. The dip seal together with polyethylene blade seals and a flexible side seal ensure the highest degree of damper seal. Enclosed blade connectors eliminate jamming and create a clean trouble free installation.
