JK67 mining axial flow fan

The design of JK67 mining axial flow fan takes into account the required dust and smoke exhaust air volume for various local ventilation working faces, the air supply distance of the air duct, commonly used air duct specifications, air resistance values, as well as the usage conditions in the mine. The maximum total pressure efficiency of single-stage and two-stage working wheels are 92% and 83% respectively, and the maximum total pressure efficiency of the counter rotating type is 85%. The specifications are complete and the adaptability is strong. There are various combinations of air volume and total pressure values for local fans, with air supply distances ranging from 80 meters to 600 meters (series use of air supply distances can reach over 1200 meters), which can meet different needs of users.
