Long-distance tandem tunnel fan
Long-distance tandem tunnel fan is a tunnel ventilator developed by the company based on the introduction of advanced European technology. This fan is durable and easy to operate. The fan can be controlled in multiple stages or in a single stage. Imported aluminum alloy adjustable blades; factory equipped with SKF automatic oiler, which can be replaced once a year; this fan is suitable for large-section and long-distance tunnel ventilation, and the air supply distance can be increased or decreased by increasing or decreasing the main engine according to the length of the tunnel; the body is sanded by a shot blasting machine to make the fan surface smoother and more delicate, enhance the paint adhesion, and adapt to the worst working environment.
