Sand Trap Louvers
The Sand Trap Louver is normally used as a prefilter for fresh air intake on 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 situations with 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.
