16.0 Sand Trap Louvres Type ‘WSL • AWSL’
2
DescriptionThe sand trap louvre is used as pre-�lter for the protectionof air conditioning plants in areas exposed to extreme levels of industrial pollution. It has a degree of separation of sand and large dust particles, even in cases of high dust concentrations. The vertically arranged sections and holes forsand drainage ensure the sand trap louvre is self cleaning andmaintenance-free. The sand trap louvre is designed to separatelarge particles at low air velocities, thus avoiding excessive dustloading on conventional plant �lters. It is not intended as a substitute for conventional supply air �ltration plant.
