I received an inquiry from Korea last week. The customer is mainly a distributor of oil separator. He never ordered any products from China before. And not clear about Chinese market and payment methods etc. He inquiried this product 6.3559.1 oil separator is our advantage product. And this oil separator is very large. Quality is best. The span life is long(3200-5400 hours). Quality is same as original. The most important is that the production time is faster. For regular products. Normally 4-6 working days can finish. In order to dispel the doubts of customer. Our factory has real production photo for this item. Sent him details filter size and photos;micron and material etc.

He was very satisfied with our products. He ready to order 10pcs as a sample for the first time cooperation by tomorrow. I sincerely hope our relationship will become better and better in future.
