Fujitsu Air Conditioning Plenums

As specialist fabricators of Fujitsu plenum boxes, our plenums meet the DW144 specifications demanded by modern engineers and architects. 

When your clients want an industrial appearance with open ceilings, our galvanised finish fits in perfectly. Our galvanised steel plenums offer durability and are an attractive alternative to ABS plastic plenums.

Duct-In plenums have various fittings, top, bottom, either side entry discharge or return. The diameter of the plenum spigot and the choice for round or oval spigots are available. 

Internally or externally lagged plenums are available to reduce moisture collection and offer the added benefit of sound-muffling properties.

We offer powder coating so your plenums can be sprayed to any colour, blending your plenums in with other HVAC services and equipment.

Duct-IN the most flexible air conditioning plenum manufacturer on the market.
