Air compressor users will inevitably encounter a problem: repair and maintenance. Sometimes you may feel that there is only a small problem with the air compressor, just repair and replace the air compressor accessories. Then the problem comes, the after-sales service price of the manufacturer is relatively high; it is much cheaper to find a general repair shop. When looking for door-to-door maintenance services, some more "conscientious" stores will take the initiative to ask: "Boss, replace the replacement parts or the original parts?"
Many people after equipment maintenance and after-sales know that in some informal maintenance shops, "stealing beams and replacing columns" often happens. Why is this the case? It is because the sources of air compressor parts are more complicated, the most important ones include: original parts, auxiliary parts, disassembled parts, etc. What do these different names mean, and what kind of background do they have?
1. Original parts
As the name suggests, the original parts are the parts with the air compressor manufacturer's logo, and their quality standards are the same as those of the factory parts in your car! Therefore, they mainly supply regular 4S stores, and some of them can also be bought at corresponding cooperative merchants, so the price is naturally expensive!
2. Sub-factory parts
There are many sources of auxiliary factory parts. One is the accessories produced by small and medium-sized suppliers who have production qualifications and use materials and processes that are close to the original air compressor factory parts, but have not obtained the purchase access qualification of air compressor manufacturers for various reasons; Another is to imitate the accessories produced directly according to the specifications of certain types of air compressor accessories. The material and process of this type of air compressor accessories will be different, but they have their own brand packaging; the last one is simply a high imitation of the original parts or genuine parts.
Due to the complex source of accessory parts, its price is also uneven, and the drop is amazing. Good quality spare parts may be half the price of the original parts, and poor spare parts may be less than a quarter of the original price or even lower.
3. Disassemble parts
The source channel of the disassembled parts is even more unreliable. Some disassembled parts are removed from some relatively new air compressors, which are basically equivalent to second-hand original parts. This kind of air compressor parts is cheap and cost-effective; while some disassembled parts, then It may be the refurbished accessories removed from the scrapped air compressor or the air compressor that had an accident. The quality of this kind of accessories can be imagined, and installing it on your machine is like a time bomb.
The quality of these major air compressor accessories is so different, so how should users choose these accessories from different sources? First of all, if you really don’t know anything about accessories, it is recommended that you contact the air compressor manufacturer to replace the original parts. Although it is a bit more expensive, it will be guaranteed by warranty.
If you have a certain knowledge of air compressors, you can choose to buy genuine parts from a regular authorized store, which will not only ensure the quality, but also ensure the stability of the equipment. After all, these accessories and equipment have been debugged and are the most suitable. . However, if you want to buy auxiliary parts, a pair of "eyes with eyes" is essential. It is safer to consult industry veterans or reliable air compressor practitioners. And for those sub-factory parts or high imitation parts that are of poor quality, don't buy them even if they are cheap. As for the so-called dismantling parts, unless you are in a desperate situation, or you are an "old driver" in terms of air compressor accessories, it is better not to touch the dismantling parts.
