Description
Sand trap louvers are an integral part of any air handling unit, usually installed at the first point of air intake. As the name of the product states, sand trap louvers prevents the sand from entering the air intake unit or equipment rooms, thus avoiding a damage to the moving parts of the equipments. They are also used for ventilation purposes in parking areas, warehouses, generator rooms, fan rooms, etc in desert or sandy regions.
Sand trap louvers are designed with a set of U channels arranged in series on one side and another set of inverted U channels arranged parallel to the first set. This arrangement creates a resistance or barrier for the sand particles in the intake air and thus settles down. The sand could be drained through the drain holes or collected in a tray.
Sand trap louvers are available with optional accessories such as bird screen, insect screen, aluminium mesh filter, volume control damper. The above model is available with 1” or 2” aluminium mesh filter, and synthetic filters are also available.
Sand trap louvers are ideal in areas where the intake air velocities do not exceed 1 m/sec. Airmaster strongly recommends high efficiency sand trap louver for higher air intake velocities
