A系 列双进风离心风轮从9寸到39寸共有15种规格。采用镀锌板(不锈钢)经自动冲床冲制后铆合而成,冷装配、无焊接、避免断裂等情况，并经由动平衡机平衡、 在保证精度的同时，具有足够的强度，使风机性能得到正常发挥。20寸以上风轮全部铆钉连结，18寸起采用加强拉杆，以保证风轮强度和稳定性，可满足风机高 速运转的需要。适用于柜式风机、空调风机、风机箱配套。风量可达2000-100000立方米/小时，全压达1400帕。风轮平衡精度G4.0。
A-double-inlet centrifugal blower wheel have 15 specifications from 9 inches to 39 inches. It uses galvanized sheet (stainless steel) and is riveted after punched by automatic punching machine; cold assembly is adopted and there is no welding or rupture; it is balanced by dynamic balancing machine, which ensures enough strength in addition of precision, and fan can perform normally this way. Wind wheels bigger than 20 inches are all connected by rivets; those bigger than 18 inches use strengthening tie bars to ensure strength and stability of the wind wheel as well as to meet the requirement of high-speed running of the fan. It is applicable in tank fan, air-conditioning fan and fan box complementary. Its air flow is as much as 2,000-100,000 m3/h, its total pressure is 1,400 Pa, and the balance quality of the wind wheel is G4.0. http://www.blower-wheel.com
