Sand Trap Louvres

The sand trap louvres made by Filtrotecnica Italiana are installed on outside air intake for ventilating and conditioning plants mainly in extremely arid and sandy areas. The working principle is based on the inertia of the heavier dust particles in an air flow that is forced through on “S” shaped passage with a sudden change in direction. The heavy particles will tend to keep their original linear motion and they will crash against the vertical blades and fall to the botton of the unit where are discharged through outlet holes. This working principle guarantees the sand trap self cleaning. Different construction materials are available to satisfy the various environments: aluminium, galvanized or stainless steel.

The grids can be supplied in standard size bearing in mind Name That Are Available All Possible Combinations.

Performance sand trap louvres
From test results conducted considering air velocity, pressure drop and efficiency Filtrotecnica indicates to dimension the sand trap with velocity between 1 and 2 m/s max. Typical efficiency with Coarse dust having particles between 350 and 700 µm rispectively 70% and 90%.
