SDS tunnel jet fan

SDS tunnel jet fan is the company USES advanced technology research and development of new products, the company fully research all over the country the subway, highway, railway tunnel engineering, and consulting experts about the tunnel design institute and tunnel installation companies, first-hand fan using conditions, product technical requirements and other relevant information, make the development of the tunnel efficiency of jet fan products than A levels and is superior to conventional axial flow fan, such as the various performance indicators and corrosion resistance, high temperature resistance, reliability and other technical requirements completely adapt to the use of all kinds of subway, tunnel, optimization of system engineering, in the domestic leading level.
Tunnel jet fan shell spinning flanging forming by imported special machine tools, both to ensure that the chassis alignment and intensity, and ensure the blade radial clearance, plastic-sprayed surface processing, good appearance and excellent anticorrosion performance.Fan blades, wheel hub by high pressure die casting machine aluminum alloy forming, the product high strength, good consistency and ensure stability good fan.Fan with fully enclosed squirrel-cage motor, H insulation grade level, the anti-corrosion class IP55, adapt to the tunnel environment use requirement.Tunnel jet fan zoning muffler and without a muffler [add set import and export (powder) inverter] two types of specifications, and points the one-way jet fan (SDS) and reversible (two-way) jet fan [SDS (R)] two kinds of forms of ventilation.Reversing the jet fan in a state of emergency and reversing switch time is extremely important, SDS (R) reversible jet fan have two switching method, electronic and mechanical can within 30 seconds and reversing fan switch to the rated speed
