Collector boxes are made of sheet steel. Electrostatically applied powder coating ensures long life of the product. Collector boxes for outdoor installation are manufactured with a secret locking mechanism to prevent external impact. The set also includes distribution box brackets and mounting kit.

Fire dampers are designed to prevent the spread of fire and smoke through the air duct system to the adjacent special special firefighting compartments. They are manufactured of galvanised sheet metal. Their design allows horizontal or vertical installation. Dampers can be made round, square and rectangular. Depending on the customer's requirements, they can be equipped with an electric actuator (when the temperature reaches 72°С the damper is closed automatically by a spring) or with a limit switch (allows monitoring of the fire damper position).
