In addition to Conduit systems Kopex also supplies Ducting products designed for the transport of hot or cold air, fumes, dust and powders in any direction.

Pliable ducting is made on the same machines as pliable conduits.  Strips of paper or metal foils are wrapped in layers to make a tube and then corrugated to give it some strength.  It is not as strong as a conduit so it generally needs more support when installed.  Often it is fitted for air conditioning into suspended ceilings or flooring which provides adequate support and protection.

As a rule of thumb, ducts containing paper and/or tinted aluminium can be used at 100 - 150°c and will be good enough for most air conditioning.  The harder surface of plain aluminium will be needed for dust extraction etc. All ducts can be bent to a minimum radius of 3 times its own diameter using two hands.  Ducting will not hold water, take pressure or flex.
