How to Choose Your Air Compressor Configuration?
Choosing the right screw air compressor solution is the first step in energy saving and consumption reduction. We recommend considering the following factors:
Air Demand Analysis: Determine your maximum or average air consumption, operating pressure, and required air quality level.
Equipment Selection: Select a constant frequency or variable frequency model, air-cooled or water-cooled cooling method, and oil-lubricated or oil-free main unit based on your needs.
System Planning: Rationally configure post-processing equipment such as gas storage tanks, dryers, and filters, and design a centralized gas supply pipeline network to maximize system efficiency.
