DuctSox fabric ductwork products were initially developed exclusively for use in the food processing industry several decades ago. The flexible fabric is a cost effective alternative to insulated stainless steel ducting and diffusers. New innovations have made maintenance and hygiene a vital advantage to using DuctSox products in food processing facilities. It is not only the outside of metal duct that gets contaminated, but the inside as well making fabric systems an ideal choice for food processing and USDA-inspected environments.
