Product Description
Castle Sand Trap Louvers are specifically designed for Egypt's desert climate — preventing sand and dust ingress into HVAC fresh air intakes and AHU inlets. Composed of two sets of inverted U-channel blades mounted vertically, they effectively separate sand particles from the air stream. Filtered sand drains through an inclined chute at the bottom. Essential for all Egyptian projects — from the New Administrative Capital to coastal developments in New Alamein.
