We received a new order of air compressor oil from a regular client in Vietnam. He purchased air compressor filter elements from our AIDA factory last year. But this compressor oil is the first purchase. The compressor oil part number is 2901170100. The life of this oil for air compressor models below 55KW is about 6000-8000 hours. He ordered 61 barrels this time. We supply replacement compressor oil for him. What I want to say is the replacement oil drum and transportation problem. About the oil drum, I sent some different color oil drums photos to him, he chosen the blue one. And Besides, I also sent the oil label photo to him. He accepted that. About the transportation, I checked with forwarder many times, we can arrange delivery by sea for him. There is a separate shipping channel. So the delivery is no problem. Customer was satisfied with our service. We will cooperate for a long time.
