ABOUT THIS EQUIPMENT

Built around the requirement.

Medium- and high-efficiency exhaust and return grilles are the terminal fittings on cleanroom return and exhaust ductwork. When the duct connects back to the air handling system the unit works as a return grille; when it connects to the exhaust duct it works as an exhaust outlet. The casing holds a filter stage matched to the room class and moves air evenly across the face to keep the room ventilated. They are used in hospital operating theatres and cleanrooms, and in pharmaceutical, food and biological laboratory facilities where a high air cleanliness level is required.
