DOWNLOAD PRODUCT SPECIFICATIONS

Overview

sand trap louvers are specially designed to separated the sand and dust from the air. It is effective and necessary to apply for ventilations and inlet ducts of air handling units. Sand trap louvers can be supplied with filters and dampers as optional.

Sand louvers are tested per ASHRAE Standard method 52.1 – 1992 (previously ASHRAE Standard 52-76) by a third party independent lab. STL protects air intake and exhaust openings in exterior walls from wind-driven sand. The design incorporates overlapping vertical sight proof blades that aid in collecting and channeling sand out of the airstream to the sloped louver sill.

 Typical Applications

Sand Trap Louver is normally used as prefilter for fresh air intake of Air Handling Units (AHU), Package Air Conditioning Units (PACU), Roof Top Fresh Air Units (RTFAU) for Air Conditioning Systems and for Fresh Air  İntake in manufacturing plants. It has a high degree of separation of sand and large dust particles even in case of high dust concentrations. The vertically arranged blade sections and holes for sand drainage ensure that the sand trap louver is self cleaning and maintenance free.It is designed to separate large particles of sand and dust from airstream at low velocities, thus avoiding excessive dust loading of conventional filters. It is not intended as a substitute for conventional filters.
