SMART-CHEM fans have been developed for conveying the air, polluted with chemically aggressive media (see table on pages 67–68) of maximum dustiness concentration up to 0,3 g/m3 and maximum temperature +40°C. The fan cannot transport explosive mixtures. Their application range is general ventilation of rooms and they are applied in ventilation systems in industry, agriculture, building construction, as well as in buildings of public services as: laboratories, store houses, hospitals, schools, canteens, swimming pools, sewage treatment plants etc. Within the SMART-CHEM series, there are six sizes of motor rates: from 0,12 kW up to 1,5 kW and of maximum volume flow 12 400 m3/h. The fans meet the requirements of the ErP 2009/125/EC Directive.
