How to replace the filte in low cost while guarantee the quality ?

The high efficiency filter of the dust-free workshop is the key component to maintain cleanliness. The air conditioning filter system of the clean room is generally divided into three filtrations, the primary filter, the medium efficiency bag filter, and the high efficiency filter. Therefore, generally, production enterprises with purification workshops pay more attention to filters, after all, this is related to the quality of the products they produce. scholar

In the domestic air filter market, most of them are mainly domestic brands. There are also joint ventures, such as AAF, Cambridge and Cornfield. The prices of primary, medium and high-efficiency filters produced by these manufacturers are quite different from those of domestic ones, and the cost performance is relatively poor, which is not suitable for domestic ones. Used by large-scale production enterprises, because the market share has gradually been eroded by domestic manufacturers.

1 Air filters are industrial consumables. Generally, the primary filter needs to be replaced every 3 months, the medium-efficiency filter is replaced at about 6, and the high-efficiency filter is replaced at about 1 year. Therefore, the cost of the product is relatively high.

2 Therefore, it is best to change the primary effect filter frequently, because the price of the primary effect filter is relatively cheap, and frequent replacement is to prevent too much dust accumulation, which will affect the service life of the subsequent medium efficiency filter and high efficiency filter. The medium-efficiency filter should use a pressure difference meter to monitor the pressure difference on both sides of the air inlet and outlet. It is better to have an alarm device. When the final resistance is reached, it will alarm to remind the medium-efficiency filter to be replaced. When replacing the initial and medium-efficiency filters, you can ask the manufacturer to replace only the filter material inside, and the manufacturer of the filter can provide such a service. And the cost is much lower than the price of a new filter. But some cannot be replaced, it depends on the structure

3 Try to use a better high-efficiency filter. The ultra-fine HⅣ fiber filter material should be better. A good filter material can effectively increase the service life and increase the dust holding capacity. If the filter material is too bad, the air volume is slightly larger, which is easy. Was blown through. That can't work. A good high efficiency filter has a lifespan of 2 years. The lifespan of a general high efficiency filter is only 1 year. It is not cost-effective to change the high efficiency and stop production. So how to choose a high-efficiency filter is a more important part.
