Russian old customer, the customer asked about a filter, the customer was filtering groundwater. The customer sends drawings and product pictures to us for confirmation. After our technicians checked the customer's drawings, they said that we could make an alternative filter. 

Now, as long as we confirm the connection port size, filter flow, filter precision and filter material with the customer, we can make a quotation to the customer after confirming these information. We sent some pictures of products similar to filters that we often do, and we also sent customers a video explanation of filters and videos of filters' work. These materials were sent to customers for reference.

When the customer saw these materials, he felt that we had great production strength. The customer felt that he would send us the sample of his filter, and we would replace it according to the customer's filter. Now the filter has been transported again. I hope we can receive the customer's filter as soon as possible
