EHA-type louvers are designed for use in environments where dust or sand is dense. The product is designed to prevent particles, such as dust, sand, etc., from entering the ventilation system of the rainwater, which can not be counted as micro. It acts as a pre-filter against sand and dust in ventilation systems.
The EHA type louvres are made from aluminum sheets. They are capable of holding particles to a high efficiency. The alternately placed vertical blades require no maintenance, with the discharge holes in the bottom plate. Since this is only a pre-filter, it is not recommended to be used alone in a system.
