Product details

Detailed introduction:

The national drum, guide, and tunnel ventilation fans look to Zibo, and Zibo looks to "Fujiang" fans. After years of effort, Fujiang fans have developed a streamlined equipment system in the factory, including automatic CNC cutting, hydraulic shearing machines, automatic rolling and spinning, mold pressing at the fan inlet and front plate, and electromagnetic heating for bearing installation. Each fan sold by our factory undergoes strict start-up testing before leaving the factory to ensure the effectiveness and service life of each fan.

SDS tunnel jet fan is a new product developed by our company using advanced technology and processes. The company has conducted extensive research on subway, highway, railway tunnel and other projects across the country, consulted experts from tunnel design institutes and tunnel installation companies, and mastered relevant information such as first-hand fan usage conditions and product technical requirements. The efficiency and A-level of the developed tunnel jet fan product are significantly better than conventional axial flow fans. Its various performance indicators, corrosion resistance, high temperature resistance, reliability and other technical requirements are fully suitable for the use of various subways and tunnels, optimizing system engineering support, and ranking at the forefront of domestic peers.

The shell of the tunnel jet fan is formed by spinning and flanging with imported specialized machine tools, which not only ensures the coaxiality and strength of the shell, but also ensures the radial clearance of the blades. The surface is treated with spray coating, which has a beautiful appearance and excellent anti-corrosion performance. The fan blades and hub are molded from high-pressure casting machine aluminum alloy, with high strength and good consistency, ensuring smooth operation of the fan. The fan is equipped with a fully enclosed squirrel cage motor, with insulation level of H and anti-corrosion level of IP55, suitable for various tunnel environments.

Tunnel jet fans are divided into two specifications: those with silencers and those without silencers (with inlet and outlet collectors/diffusers). They are also divided into two ventilation forms: unidirectional jet fans (SDS) and reversible (bidirectional) jet fans (SDS (R)). The forward and reverse switching time of reversible jet fans is extremely important in emergency situations. SDS (R) reversible jet fans have two switching methods: electronic and mechanical, which can switch to the rated speed of the fan in 30 seconds.

The specifications of SDS tunnel jet fan range from 0630 to 01600mm, with a maximum thrust of 3500N. The air volume can be met by changing the number and angle of blades, and suitable fans can be selected for any load and working condition.
