performance introduction

 

4-2X79E and 4-79A centrifugal ventilators deliver air and other unnatural, harmless, corrosive gases to steel products. The gas is not allowed in a viscous substance, containing dust and hard particles less than 150mg/m fand. Gas temperature shall not exceed 80 degrees centigrade. The fan has good aerodynamic performance, and the impeller and belt are corrected by strict static and dynamic balance. The utility model has the advantages of stable operation, small vibration, high efficiency and long service life. Widely used in industrial and mining enterprises, large buildings, hotels, restaurants, indoor ventilation, smoke extraction.
