The sand trap louver is usually used to filter the fresh air entering the air conditioning packages, roof tops and fresh air of the air conditioners in factories and production sites. The type of placement of the vertical blades of this type of louver causes a large amount of sand and coarse dust particles to be separated from the air path and directed to the outside through the outlet installed at the bottom of the louver. This mechanism has made the sand catcher louvres to be usable with a long life without the need for maintenance. Using this type of filter before the main filters of the air conditioners makes the dust density on the air conditioner filters less. And as a result, replacement and cleaning will be needed in a longer period of time.
Sand trap louvre is very suitable for use in dusty and sandy atmospheres. The efficiency and operation of this type of louvre will be very suitable in low air speed; It is recommended to consider the largest possible size when designing and selecting the sand catcher louver (the air velocity on the blade should not exceed 1.7 m/s.). Sand trap louvre can prevent snow and rain from entering the building. It is possible to provide a bird net or insect net behind the louver.
