Is it true that 200 air compressors are on the market?

Before, I saw a piston machine with a price of 200 pieces on a B2B platform. When I saw this price tag, I didn't dare to believe it. Because even a small piston machine cannot be bought for 200 yuan. As we all know, the main cost of air compressor is from the host. The larger the size of the host, the stronger the ability to handle gas, and the higher the price. Generally speaking, I have seen even the cheapest mainframe cost ten thousand dollars. Even if it is OEM, the cost cannot be so low. Unless the seller doesn't want to make money. So what is going on with this 200-dollar air compressor?

out of curiosity, I contacted the manufacturer along the contact information left by the online merchants. In the telephone consultation, he said that he was really selling an air compressor. When I asked the merchant for the physical map, the merchant said that if necessary, he could make an appointment with me to see the physical map himself. On the day of the agreement, the manufacturer showed me an air pump. Although the principle of the air pump and the air compressor are the same, the appearance and structure are completely different. Users who have come into contact with the air compressor can see it at a glance, and the price of 200 yuan for an old air pump is completely in the normal range. Later, I debunked the tricks of the merchants. The merchants said that a piston machine could cost only 200 yuan. Later, they quoted me the price of a 30KW piston machine, which was much more expensive than Deria of the direct camp factory. It really scared me, and then the matter went away.
