Many people think that India's side channel blower is a kind of material benefit, but many customers have ignored a problem. In the face of cheap labor force, it is not the quality of the personnel is not poor, but the lack of high-precision production equipment. In the pursuit of precise and rigorous machinery, compared with China, China's side channel blower export is more than three times that of India's China has a mature mechanical production system, which is not only batch production, quality is the first in all countries.
From the perspective of control strength during the epidemic, China is now a country without new coronavirus, and the fans produced are very safe, while the number of confirmed cases in India is already the second in the world, second only to the United States. Therefore, when selecting side channel blowers, we must understand the international market, and do not blindly covet cheap.
Due to the wide use of side channel blowers, and its selection is relatively complex; there are many brands of fans in the domestic market, customers must pay attention to the following points when purchasing side channel blowers:
1. Simply understand the strength of the supplier scale: registered capital, business scope, whether the company has obtained the necessary certificate.
2. Supplier's enterprise background, historical performance and growth: whether the company's actions are legal and standardized.
3. Whether the product reliability, quality assurance and after-sales service are perfect: whether the product has passed CE certification, Rosh certification, SGS certification, etc.
4. Whether the logistics is timely, payment method, etc
The above customers in the purchase of side channel blower must pay attention to, in order to avoid low price but product quality and after-sales.
Due to the wide use of side channel blower, its selection is relatively complex. Generally speaking, the following two steps should be followed:
1. It is necessary to determine what function the side channel blower is used on site, whether it is suction or blowing, and find out the pressure flow curve corresponding to the side channel blower; if the curve is misread, sometimes the selected products can not be used;
2. According to the calculated pressure and flow, the working curve above the working point corresponding to the pressure and flow can be found on the curve chart, and then the high pressure fan model is selected according to the working curve;
As long as it is different work site, the demand for pressure and flow is not the same, so, to get relatively accurate data, we need to carry out relevant calculation. This needs to be carried out by professional designers or consulting professional companies.
