Air return ARRT 40S

Air return — this is the system, where the aspirated air, after filtration in the dust extraction unit, is not discharged into the atmosphere, but fully or partially returned back to the production workshop. That allows decreasing greatly the loss of heat in the winter time and, therefore, decreasing the expenses for heating. In the “clean air return” option the winter/summer mode is foreseen that enables to dump air fully or partially to the street. Distribution of the filtered air in the production district is provided through the perforated air pipes that ensures the equal distribution of the air flow.
