Galvanised Plenum Boxes

Duct Warehouse manufacture a range of bespoke galvanised plenum boxes.

Our boxes are generally used for the supply and extract of air through ventilation grilles and air conditioning equipment. A rectangular connection is available with or without an external sheet metal fixing flange. Egg crate, single and double deflection grilles are face fixed and require an external sheet metal flange. Diffuser grilles are fixed through the side of the plenum box and do not normally require a fixing flange, although a flange can be provided if required.
