Profile: KE Fibertec UK Ltd offers fabric ducts, air socks and textile ducts. Our fabric ductwork systems are bespoke and will be carefully designed to provide with the best possible solution to specific ducting requirements. In passive low impulse systems the air diffuses through a permeable material. In high impulse systems air is distributed solely through holes. KE - low impulse textile ducting is an ideal solution for the delivery and distribution of cooled air, particularly suitable for hygiene, comfort and temperature control. Our textile based low impulse systems are woven from CS polyester yarn, and the textile surface acts as a fine mesh, allowing the supply of air to pass through the surface at a very low uniform discharge velocity which is normally less than 0.1 m/s. Our low impulse textile duct is produced using round ducts.
