Description
The main features of the G, Y7-41 type industrial boiler induced draft fan are: high fan efficiency, high total pressure, low noise, flat performance curve, and a wide economic operating range. It uses backward curved blades, and the efficiency at the ideal operating point is 86.5% with a noise level (A-weighted) of LS=11.5 decibels. These two indicators are better than those of various existing industrial boiler induced draft fans in the country. If this fan achieves the same flow and pressure as other models, the fan shaft speed can be significantly reduced (generally reduced by 200-800 RPM), thus significantly lowering the fan noise and ensuring stable and reliable operation.
