Roof Exhaust Units ROOF-CM ATEX
They are used for ventilation purposes in apartment, public or industrial buildings by sucking out the dusty air. They are easily installed and do not generate a lot of noise. Their engines are located outside the airflow's reach. Their construction consists of steel frame with protective grid, an upper technopolymer hood, openings for better engine cooling and impellers with back-pointing flaps.
This model is the fireproof one.
