4-75kW Q345 High strength low alloy steel Industrial Centrifugal Blower Fan

The 4-75kW Q345 High strength low alloy steel Industrial Centrifugal Blower Fan is designed for high-temperature flue gas and industrial exhaust emission. Constructed with durable Q235 carbon steel for heat and corrosion resistance, it offers robust performance. With a power range of 4-75kW, it delivers high airflow and pressure, ideal for sintering processes and ventilation systems in metallurgy, chemical, and building material industries, ensuring efficient and reliable gas handling.

• Capable of outputting higher outlet pressure while providing more gas flow with lower noise. Stable operation at higher media temperatures.
• The fan speed can be flexibly set by matching different pulley diameters to make the fan run at the highest efficiency point and reduce energy waste.
• Motor sliding guides are provided for easy tensioning of the belt to reduce energy loss due to belt slack.
• The bearing housing is reserved for temperature and vibration sensor mounting positions, for convenient installation of fan operation monitoring devices.
• Uses liquid lubricant - no need to open the bearing housing to replace and fill the oil. The bearing housing has an observation window for easy monitoring of lubricating oil quality and level.
• The bearing housing uses a labyrinth mechanical seal with unique leak-proof oil design, vent hole at the top, and sealant on the joint, completely eliminating oil leakage possibilities.
• The impeller is annealed to completely eliminate internal stress from welding, preventing creep and cracks.
• The impeller undergoes high-standard dynamic balance correction to ensure stable fan operation.
• All products undergo running and vibration tests after production for reliable operation.

• Delivers large gas flow with low noise when pressure requirements are met.
• Flexible speed setting through different pulley diameters for optimal efficiency.
• Motor sliding guides enable easy belt tensioning to prevent energy loss.
• Automatically reduces motor load when airflow resistance increases, preventing motor burnout.
• Simple installation with monolithic bracket design, requiring minimal technical support.
• All products undergo running and vibration tests after production.
