High Efficientlly Metro Tunnel Axial Jet Fan

JYT series jet fan is the new product developed by Motexo Fan depending on the results of mechanism research from Shanghai Jiaotong University, and adoped the advanced technology from Japan and Germany. The technology center of Motexo Industries is focusing on research and innovation for sustainable development. The company has established wide communication with international enterprises, and taken sufficient research on metro, highway tunnel, railway tunnel, dams project systems, as well as consult with the experts from the corresponding metro design institutes, tunnel design institutes and tunnel engineering enterprises So the company knows well the application condition of jet fan and accumulates wide experience in technology, quality and application condition. The efficiency and A-weighted noise level of jet fan is better than that of the tradition axial fan. The intention of Motexo Industries is to select the jet fan with the best performance, to optimize the various engineering systems and to keep leading position in the domestic industry.

JYT series jet fan has high quality assurance depending on the advanced technology. The casing is forming by spinner. The tip of impeller is processed to make sure the alignment and the tip clearance. The hot dip galvanized surface provide good appearance and excellent anti-corrosive performance. The blades and hub are made of alu-minum alloy by high/Low pressure die-casting by casting model which is made by Toshiba CNC. 

• Motexo Industries JYT series jet fan with low noise, large flow and high thrust the advantages of the indicators are in line with JB/T10489-2004 "Tunnel jet fan technology with conditions" and GB/T19843-2005/ISO13350: 1999 "Industrial Ventilation plane jet fan performance test "requirements.

• The required working conditions, the fan's design life of at least 10 years (except wearing parts), the first overhaul of security before the operating time of not less than 20000h.

• High temperature resistance performance: Fan in the gas temperature 280 ℃, 60min in continuous operation,will not be mechanical, electrical or structural failure.

• One-way flow of jet fans in the reverse flow and positive ratio of up to 50% -70%; two-way reversible jet fans in the reverse flow and forward flow ratio greater than 96%.

• The model of jet fan noise limits are in line with JTG/TD70/2-01-2014 requirement: fan in the wild, away from the fan outlet center 10m, with the fan axis measured at 45 ° to the A sound level does not exceed 77dB (A).

• Hanger bearing fan installed to ensure the fan static load strength of 15 times, easy installation, hanger struc-ture of the actual size of the tunnel embedded parts can be adjusted.

• Jet fans installed in the tunnel limit 15cm-20cm office building, fan axis with the axis parallel to the tunnel,the fan setting method should use fixed or suspended.

• Jet fan, after all components are corrosion preventive treatment, two high-temperature corrosion primer coating, two high temperature finish. When specified, with stainless steel muffler plate , fan surface galvanized, stainless steel bolts connecting bolts.

Motexo jet fan is mainly used for longitudinal ventilation of roads and railway tunnels,dams projectand can also be used for other similar occasions, such as auxiliary tunnels and sedimentation tanks.
