Generally, a newly purchased screw air compressor needs maintenance after a period of use. Maintenance can be divided into minor maintenance and major maintenance.
1. Minor maintenance
You only need to replace the air compressor oil and oil filter. Generally, the new machine is replaced after 500 hours of operation.
2. Major maintenance
In addition to replacing the air compressor oil and oil filter, you also need to replace the air compressor air filter element and oil-gas separator element, motor grease, etc. This maintenance is performed after the machine has been running for about 3,000 hours. It depends on the working environment. If the environment is very dirty, such as a lot of dust, this time should be shortened appropriately. The purpose of air compressor maintenance is to allow the machine to operate better in the best condition. Just like car maintenance, good maintenance will greatly reduce the machine failure rate, which not only saves the time and effort brought by frequent maintenance, but also prolongs the service life of the air compressor. Therefore, the maintenance of the air compressor must be done well at ordinary times, and don't be reluctant to spend the maintenance money, otherwise, when the main engine carbon deposit bites this kind of fault, it will cost a lot. How much does it cost to maintain a screw compressor? To answer this question, it depends on the brand and size of the screw compressor you bought. The smaller the machine, the lower the maintenance cost, and vice versa.
