Extract Ducting

Negative Pressure - extract ducting So far the only Fabric Ducting company to offer a production extract duct. 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 of course that being fabric it would normally just collapse. We stop this by installing 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.
