FRP horn blower-vacuum glass shell composite material made of steel, motors, fan blades are used high-quality aluminum alloy
Material. The use of suction fan series of design principles. Fans will be around the hot, hot gas quickly pumping. Effective area
Axial-axial-flow fans pumping effect. Fans of the series are light weight, smooth running, low mechanical noise, it is not easy ageing,
Resistant good performance, and ease of installation advantages. Fans back blinds air downstream of design principles. Can be based on the blinds
Fans of the opening and closing operation of state autonomy.
