Electronics DC24v Equipment Cooling Fans Tangential Fan For Refrigerator
12V 50x350mm Cross Flow Fan, high air flow and long life expectancy , are widely used in ventilating Elevator, as well as industrial production equipment, medical equipment, home appliances, etc.
Our cross flow fans, also named as tangential or blower wheel fans will generate a wide, even flow of air parallel to the unit being cooled, insuring greater efficiencies and lower noise ratios compared to axial fans.
