Product Details
Product Overview
The Explosion-Proof Type A mobile centrifugal fan supports grain aeration and ventilation projects where dust protection is required. Airflow, pressure, motor configuration and accessories can be selected to match the storage or drying system.
Mobile Centrifugal Fan (Explosion-Proof Type A) belongs to Yosinda’s grain ventilation fans range. Typical uses include Suitable for deep-grain aeration and moisture reduction in flat-storage warehouses, silo air exchange and fumigation circulation, shallow-grain ventilation, and air supply or exhaust for grain-drying towers. For grain aeration, the depth and condition of the stored grain affect resistance and operating duty. Drying, moisture reduction, silo air exchange and fumigation circulation require different selection inputs. Specify the storage layout and handled atmosphere, including any dust protection requirements.
Published configuration information includes Fan Type: Centrifugal / Axial / Mixed flow; Model: 4-72, 4-79, 6-31 etc.; Air Flow、 Total Pressure、 Motor Power: Customized upon request. 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.
