220mm x 90mm Rectangular Single Blade Damper

Small scale rectangular plastic ducting is becoming commonplace in new build homes as increasing demands for energy efficiency and clean air lead to more homes being equipped with heat recovery systems. Rectangular single blade dampers are designed specifically to suit these types of ductwork, allowing airflow through air terminals to be adjusted to suit the location within the building. The damper is designed to be a male fit to 220mm x 90mm plastic ductwork, and is adjusted using an ergonomic blue plastic handle, which is lockable with a screw in the centre of the handle. Manufactured from galvanised steel as standard, stainless steel construction is optional with grades 430, 304 and 316 (marine specification) available for increased corrosion resistance.
