Not content with just producing parts of ventilation units, in 1974, research for producing final products was initiated. Motors were obtained from Profilo company and coupled with the manufactured casing and axial fans, manufacturing of industrial aspirator was commenced. In 1980, Profilo company stopped producing the motor they supplied us and this led to the in house research about motor production and finally in November of 1981, we started to produce the motors used in the industrial aspirators in-house.
