Fabric Extract Duct
Prihoda are the only Fabric Ducting company to offer an extract duct as a standard production product. Normally of course we require positive system pressure to inflate the fabric duct and deliver the air. The problem with a negative pressure or extract duct is that, being fabric, it would normally just collapse. We stop this by inserting the return air duct within a very rigid frame – designed to withstand the negative pressure effect on the duct, and to keep it in shape and in tension, so that aesthetically it continues to look good, as well as work well.
Available in all 9 stock colours and in exactly the same material as the supply air Fabric Ducts (and we can also use this rectangular system as a supply air duct if required).
