(1) "Inflatable Air Blower" diameter fan blade twist angle and size: the larger the diameter of the inner blades, wind blades cutting the air to produce greater; the harder twist angle increases cutting wind, the wind blowing out large hardness ; the more the number of blades of wind shear wind denser, softer effect of wind, wind and more stable, generally five blades of fan blades inside diameter than the big three, and three blades twist angle larger than five blades, Therefore, five large wind blades, the wind effect and soft, three-blade wind speed, wind effect hard.
(2) identify the "Inflatable Air Blower" Blade Material bad: Fan blades are made of a new material PP, AS new materials and recycled materials. First, we must learn to identify new materials or recycled materials: recycled materials are processed by injection molding or expect from waste, there is a big smell, not environmentally friendly, low cost, becomes very brittle, fragile in cold weather, while not environmental protection. Identification of the most direct way back to the material or materials are environmentally friendly: Look Blade whether the recyclable logo "," if there is recyclable logo, indicating that the material is environmentally friendly new materials, if the fan is not specified by the back feed material composition; secondly There is also a simple visual method: "Inflatable Air Blower" new material due to material of high purity, transparency is relatively large, back to the material by impurity ingredients, so the less transparent, can pivot from one side to the other side! .
