Use: suitable for the suctin of vitiated air flue gases and vapour from the environment.They are very useful during the summer season in those environments where air changes are necessary in order to keep the room ventilated. They are also used for the aeration of workshops, founderies, cement factories, tanneries, joineries, and for chemical mechanical and metallurgical industries where big air volumes have to be sucked at low pressure. Minimum working temperature – 20 °C, maximum + 60 °C.
