QADNET make Sand Trap Louver is used as pre-filter for the protection of air conditioning plants in area exposed to extreme levels of industrial pollution. It has a high degree of separation capability of sand and large dust particles, even in case of high dust concentrations. The vertically arranged sections and holes for sand drainage ensure the sand trap louver is self-cleaning and maintenance-free.
The STL is designed to separate large particles at low air velocities, thus avoiding excessive dust loading of conventional filters. It’s not intended as a substitute for conventional supply air filtration plant. For bigger sizes, several sections can be combined to provide any combinations of overall width W or height H.
