High Integrity Ductwork

Our high-specification and fully welded ductwork solutions are designed for the most challenging dust, fume, and odour issues in industrial environments. The Airmatic team are proud to be the UK’s leading provider of High Integrity Ductwork Systems. This service focuses on fully welded ductwork measuring at 1mm or above in thickness and is made from coated mild steel or various grades of stainless steel. This type of ductwork is used in high-pressure environments, where contaminants are more abrasive, and fumes are more harmful. All ductwork is rigorously tested to be able to withstand these types of environments.
