Which brand of air compressor is good?
Thread Content
Valves require instrument air, and the client wants to use higher-quality equipment – so which brand is good? Additionally, I would like to know whether screw compressors or piston compressors are better for supplying instrument air There are also valves that require instrument air; should the air compressor be kept as a backup? Thank you. PS: Following the principle of using only what is necessary, which brand and model would be the most suitable?
We use ATLAS air compressors; they are of good quality. The price of spare parts is a bit high, but the after-sales service is satisfactory. In China, people use Liuzhou Fuda compressors.
First, one unit should be in operation while another is on standby; the screw compressor, piston compressor, or centrifugal compressor should be selected based on the required air volume. For instrument compressors, oil-free lubrication compressors should be used, along with an air drying unit installed after the compressor. There are many brands of small air compressors; you can search on compressor-related websites.
We use Sulzer products from the United States; their quality and service are excellent, but the prices of their spare parts are relatively high.
Foreign brands are expensive both in terms of cost and maintenance; for the Liuzhou Fuda brand, turn to me – I’ll help you with the design. wangyongwell @sina.com
For large capacities, a centrifuge can be considered; those from Ingersoll Rand work well. If the capacity isn’t very large, it’s better to use a screw compressor; those from Atlas, Sulzer, and Caesar are all quite good. I haven’t used domestic ones much; if the cost is acceptable, it’s better to consider imported ones.
We use Ingersoll Rand units, two of them; basically one is in use while the other serves as a backup. Sometimes we need to use both units, and the quality is pretty good.
We use air compressors from Shaanxi Gas Turbine and Ingersoll Rand, and both have decent quality. Ingersoll Rand’s spare parts are really expensive.
We’re also using ATLAS air compressors, and they seem pretty good – they are screw-type
Ingersoll Rand’s small air compressors are good
