In the new airhood Arbin and Promea brought together a number of novelties in one product. The blow-moulded air channel contains an airflow indicator that makes the hood suitable for a high safety category. The entire product is assembled without any glue or a single screw, because of the bayonet hose connection, the click joinings between shield segments and the shield fasteners. The shield fasteners keep together a number of spray sheets at exactly the same tension. It prevents dust or spray-dust to adhere between the different layers. Promea designed and engineered all parts and developed the product graphics and packaging.
