Architectural or External weather louvers as a protection of air conditioning systems against the direct ingress of rain, leaves and birds into fresh air and exhaust air openings. Under certain unfavourable conditions, such as heavy rain, and depending on the airflow velocity it might happen that slight quantities of water enter together with the air. This is why the airflow velocity in fresh air openings should not exceed 2 – 2.5 m/s.
The sand trap louver is used at the fresh air inlet duct of the air handling unit. It can lower the dust loading of conventional filtration as it is designed to separate large size sand particles at low to medium speeds. It is also fitted with a bird screen mesh protect against the unwanted objects. The sand trap louver is a self emptying system. It has a set of holes at the bottom face of the casing to discharge separated sand particles.
