Xiamen, million liters Electrical Equipment Co., Ltd. was established in 2006 to stop procurement of marketing model to serve our customers. The company currently has four chain stores, shopping malls mainly wholesale - wire and cable, labor supplies, industrial casters, packaging materials, transportation equipment, abrasive abrasive, hardware tools, power tools, lifting spreader, Blowers, handling equipment and other all types of enterprise, has the advantage of cheap, uphold the real cost savings for the customer service and the concept of business development for the majority of manufacturers to provide strong support. In the past, ventilation scheme, it often based on the number of ventilators space to determine which products and quantities use. This is a small space, the effect is very obvious roughness caster manufacturer, you can even saw a steam bath with suction fan operation quickly discharged to the outside. But in the big wide enclosed space, such ventilation is not obvious: relatively large proportion of dust, moisture, carbon dioxide, and the poor quality of the air roughness caster Which is good, is concentrated in the building bottom suction fan on the roof and on the air every corner did not work, but rather in that of personnel and equipment.

Fan has a long history. China in BC for many years been manufactured simple wooden windmill hulling, its action principle is basically the same with modern centrifugal fan. In 1862, British Guyana Bell invented the centrifugal fan, the impeller, housing for the concentric type roughness caster, housing made of brick, wood after the straight blade impeller, efficiency is only about 40% roughness Wheels and distribution, mainly for mine ventilation. In 1880, it designed for mine discharge volute casing air supply, and backward curved blades centrifugal fan, the structure has been more perfect. Roughness Wheels _ Xiamen power tools wholesale distribution _ roughness Wheels million liters provided by linking Xiamen Electrical Equipment Co., Roughness Wheels _ Xiamen power tools wholesale distribution _ roughness Wheels is one hundred million liters in Xiamen Electrical Equipment Co.
