The outer frame adopts advanced CNC automatic processing technology, one molding, thick galvanized layer, strong corrosion resistance, and the bottom is equipped with a drain. Aviation aluminum alloy wheel hub, hot - pressed casting, light material, high strength, good toughness, no fracture. Six new stamping stainless steel blades, no deformation, no fracture, beautiful and durable. The whole machine has been tested by dynamic balance, and its reasonable blade Angle ensures that atmospheric flow is generated and almost no noise is generated. The louvers are made of high strength hot galvanized sheet and have a unique automatic opening device (push open and close mechanism). Ensure that the louvers are completely open and closed, keep 90° under any circumstances, close tightly, wind, dust, rain proof. The push-open and closed mechanism is made of industrial nylon injection molding with good toughness, high strength and long service life.
The characteristics of the push-pull fan are:
1. The rack material corrosion resistance is strong, made of thick galvanized sheet; 2. The frame adopts CNC machine tool technology, high precision; 3. The wheel hub using aluminum alloy cast steel two kinds: new deformation stamping forming blade; 4. Reasonable blade Angle can make the air flow reach a higher level;
