Sand Trap Louvers
Sand Trap Louver is normally used as pre filter for fresh air intake of Air Handling Units (AHU), Package Air Conditioning Units (PACU), Roof Top Fresh Air Units (RTFAU) for Air Conditioning Systems and for Fresh Air Intake in manufacturing plants. It has a high degree of separation of sand and large dust particles even in case of high dust concentrations. The vertically arranged blade sections and holes for sand drainage ensure that the sand trap louver is self-cleaning and maintenance free. It is designed to separate large particles of sand and dust from airstream at low velocities, thus avoiding excessive dust loading of conventional filters. It is not intended as a substitute for conventional filters. Sand trap louvers are specially designed to separate the sand and dust from the air. It is effective and necessary to apply for ventilations and inlet ducts of air handling units. As the assembly comes with complete aluminum extruded profiles unit, it is corrosion resistant and suitable for different weather conditions. Sand trap louvers can be supplied with filters and dampers as optional.
Stationary louvers are designed to provide air intake and air exhaust openings in building exterior walls to protect against direct ingress of rain. The blade centers are at 45 degree and have a high free area to provide minimum resistance to airflow.
