It is difficult for industrial fans to make big differences, and even the product layout is the same between brands, and Dawang ventilation is also inevitable. Although it won the annual scientific and technological innovation demonstration enterprise in 2019, the performance of Dawang ventilation market is not impressive, and there are few cooperative enterprises. The patented technology mainly involves safety aspects such as shock absorption and anti-fall of industrial large fans. The products are similar to many brands in terms of core components and technology.
In terms of fan blade material and shape, Dawang Ventilation and Hengzhengtong brand are the same. In terms of wheel material and technology, it is consistent with Orbit, Guangdong Ruitai, Fusida, and Karma.
The quietest of Dawang ventilation products is the W.Fans series, which uses a permanent magnet brushless motor with a noise of 39 decibels. The blade material is 1.5mm thick 5052 aluminum alloy plate, while the fan blade material used by the four brands of Orbit, Guangdong Ruitai, Fusida and Kaxiao is 6063 aluminum alloy plate.
Model 5052 is a representative alloy of medium strength, with good corrosion resistance and formability, especially high fatigue strength, but the coloring effect is not ideal. The aluminum plate bending process is adopted, and on the premise of ensuring the purity of the aluminum plate, the fan blade is basically free of impurities, and there are no excessive material shortcomings and risks, but the mass production cost is high.
The 6063 model of the fan blades of the four brands of Orbit, Guangdong Ruitai, Fusida and Kaxiao is a representative alloy for extrusion, with good extrusion, complex cross-sectional shape, strong corrosion resistance and easy coating, and good processability. The corresponding aluminum extrusion process is excellent in processing and low in cost, but it is a test of process technology and quality control of enterprises.
All of the above have their own advantages and disadvantages, and ultimately they should be chosen according to the needs and cost budget of the site. If you have a custom color requirement for the fan, the 6063 fan blade is recommended. If you have a high demand for durability and a high budget for fan blades, the 5052 model is more suitable.
The height of the building for the installation of Dawang ventilation industry fan needs to be greater than 4.5 meters, which is suitable for concrete beams, I-beams, round pipes and steel beams and other building structures.
