seaHawk Acoustic Polyester Ducting has an inner and outer layer of flexi-ducting, separated by a layer of insulating Dacron in between them. As air travels through the Duct it causes the inner layer of the flexi-ducting to vibrate which would normally create a humming noise but the insulating layer of Dacron in the acoustic ducting prevents the vibration from getting from the inside layer to the outside layer of flexi-ducting, reducing the hum from the Duct vibration and dampening the sound of a ventilation fans by about 50%. To maximise the sound reduction of the fan make sure the Acoustic Ducting is stretched as straight as possible.

Polyester/Dacron-filled ducting reduces skin irritation when it is handled. This seaHawk Acoustic Polyester Ducting is 5m in length, has a grey insulation layer, and the inner ducting is fabricated with very fine holes. The outer side of the ducting is completely light and air-tight in shiny aluminium foil.

Available in 200mm and 250mm.
