Direct Start Tunnel Fan SDDF-I

Product Advantages

Compact structure, safe to use

This series of fans consists of a collector, primary fan, secondary fan, motor, bipolar silencer, etc. The body and structure are welded from steel plates. The impeller is made of aluminum alloy through high-pressure precision casting, subjected to X-ray flaw detection, and selected high-quality blades ensure the raw materials are more precise and sturdy. The fan adopts a direct connection between the motor and impeller, ensuring reliable transmission. The overall structure is simple and compact, sturdy and durable, safe to use, and easy to maintain.

Three-dimensional flow aerodynamics

The impeller adopts three-dimensional flow aerodynamic theory, variable-sweep combined orthogonal blades, and aircraft turbo engine blade fans, among many other high-tech design and manufacturing techniques.

High efficiency, good performance

The whole machine features compact structure, low noise, high efficiency, good aerodynamic performance, and high wind pressure. It operates stably in the working area and has a wide high-efficiency application range. According to the different ventilation requirements of tunnel excavation face lengths and roadways, it can be used as a whole machine or in stages, thereby reducing energy consumption and saving energy. It is an ideal device for medium and long-distance local ventilation in tunnel excavation.

Electric system

It adopts a controller dedicated to engineering machinery, with better dust resistance and water resistance, and an extremely low failure rate. Through integration with self-developed cloud platform technology, it can perform remote fault diagnosis, maintenance reminders, and other functions for the equipment.

Ultra-quiet

The silencer adopts an externally wrapped composite noise reduction device, and the main unit is equipped with a silencer, giving the whole machine ultra-quiet characteristics.
