Product Details
Product Overview
The 6-31 series provides the pressure required for fluidized-bed boiler air systems, induced-draft service and dust removal. High-temperature construction and project-specific motor options are available for demanding installations.
6-31 Series Centrifugal Fan belongs to Yosinda’s centrifugal fans range. Typical uses include Fluidized-bed boiler primary and secondary air, high-pressure induced draft and dust removal. For a ducted centrifugal installation, the fan must overcome the resistance of the complete system. Include filters, bends, dampers and discharge conditions when specifying pressure. Outlet orientation and access around the drive also affect the installation and later maintenance.
Published configuration information includes Fan No.: 2.8#~22#; Air Volume: approx. 378～144000m³/h; Total Pressure: approx. 471～21164 Pa. Range figures cover different sizes and operating points; they should not be read as simultaneous performance for one unit. Confirm the selected fan’s performance and dimensions with our engineering team.
Manufacturing takes place in Wuhu, Anhui, China. Send the duty point, local voltage and frequency, drawings and destination with your inquiry. Yosinda can review the mechanical configuration, motor options and export packing for the order. The quotation confirms the delivery scope and applicable inspection requirements before production.
