The K35 type mine axial flow fan is the main ventilation equipment suitable for ventilation in the main shaft roadway of metal mines. It has 8 specifications and a power range of 4kw-75kw to meet the requirements of various working conditions and pressures. It is also suitable for zoning ventilation and auxiliary ventilation in large, medium, and small mines. Multiple fans can be connected in series and parallel to form multi-level stations, solving the ventilation problem in high shade network mines.

Adopting a welded structure of steel plates and sections, the motor is directly connected to the working impeller, with a simple structure, easy maintenance, and reversible reverse air flow. Its reverse air flow rate is 65% -85% of the forward air flow rate, which can fully reach 60% of the safety regulations. There is no need to set up a separate reverse air duct, and it has the characteristic of fast reverse air speed. The fan casing above No.11 is composed of upper and lower halves, and the wind bolts are connected as one, making it easy to transport underground.

To increase the static pressure of the fan and reduce outlet losses, a diffuser can be added according to user needs.
