I had a very good customer from Thailand. He is dealer and his client is city government. They need automatic self cleaning filter.

Self cleaning filter Working principal:

When the pressure difference reaches the preset value, or when the preset time is due, the filter will start a self cleaning prcess, during which, the brush in the filter screen will rotate, brushing down the impurities caught by the filter screen, and then the impurities will be discharged from the drain valve.

According to client's demand. We recommend him DN50. He wants to order 2 Unit. I make a detailed techncial data and drawing to my client. He is very satisfied with our scheme.

He will place an order to us next week. I sincerely hope our cooperation will much better and better.
