Double deflection supply air grilles manufactured of extruded type 50S anodising grade aluminium with individually adjustable front vertical and rear horizontal louvres held in place by starlock washers and spring wire.
The two sets of individually adjustable louvres - vertical and horizontal - with or without a damper attached, allow these grilles to provide maximum flexibility of adjustments for spread and throw requirements. The multi directional flexibility allows for multi-directional air supply. They are recommended for high sidewall, bulkhead or duct mounting and can be used for heating, cooling, or ventilating applications.
