备注：以上数据为产品生产过程中得到的平均值，实际过滤性能会根据过滤器设计参数的变化，以及滤材在技术参数范围内正常变差而变化，本公司一直努力定义我们的产品，因此保留技术参数改变的可能。

The above are the average data obtained in the production process The actual filter performance will vary according to the filter design parameters.There are also variations due to the technical parameters tolerance.

We always try improving our products, so we reserve the possibility to change the technical parameters.
