The DH grille is a supply and exhaust diffuser with individually adjustable horizontal and vertical aluminum fins. The DH grille
is suitable for most premises.
Mounting can be done with clip-ons or hidden screws. Standard grilles kept on stock, up to sizes with area of 0,12 m² will be delivered with clip-ons. For custom-orders, up to 0,2 m² the grilles can be delivered with either clip ons or hidden screws. For ceiling installation, or together with control damper the use of hidden screws is recommended. Mounting the grille together with a plenum box is only possible with clips and without mounting frame.
