The fresh air entering the air conditioning packages of the building’s central engine rooms and the rooms housing the air conditioning equipment in industries and manufacturing sites, is filtered using sand trap louvers. This sort of louver’s vertical blade arrangement results in significant separation of sand and coarse dust particles from the air stream, which is then directed outside via the outlet set up at the bottom of the louver. The sand trap louvers may now be used for a long time without needing to be maintained thank to this technology.

The concentration of dust on the air conditioner filters will be reduced by using these kinds of filters prior to the main filters. Therefore, cleaning and replacement will be required over a longer length of time. These items can be produced from stainless steel, galvanized iron, and aluminum.
