Choose the right industrial screw air compressor for your application-determine which air compressor is based on various compressor technologies, sizes, CFM (cubic feet per minute) and PSI (pounds per square inch) requirements, and other specifications Fitting is not an easy task . Here are the five most common mistakes to avoid when choosing an industrial air compressor:

1.Choose the wrong compressor technology. - There are so many compressor technologies on the market! From screw and piston (reciprocating) compressors to scroll and centrifugal compressors, choosing the compressor type that best suits your specific application can be difficult. When making a decision, keep the following points in mind:

Screw air compressors are very suitable for companies seeking compressors with lower noise levels, higher energy efficiency levels and less maintenance requirements, as well as applications that require longer working cycles and more daily operating hours.

Piston air compressors are an excellent choice for companies with lower demand, when the initial compressor cost is more important, but the daily operating time and duty cycle requirements are lower. They are also ideal for locations with less available space.

Scroll air compressors are very suitable for applications in R&D, universities, breweries, dental clinics and hospitals. These types of compressors run very quietly and provide 100% oil-free air.

2. Select the wrong compressor size. Choosing an air compressor is not suitable for a "one size fits all" approach. Knowing the exact operating pressure and maximum compressed air volume flow rate of the process is key; you should also consider potential business or facility expansion. If you choose an oversized air compressor, it will cause huge energy costs, which is mainly caused by the surge of energy generated when the air compressor starts. Excessive start/stop cycles can also lead to motor burnout, future mechanical problems, and potential compressor failure. On the other hand, the pressure drop and the inability to complete the task (such as the inability to complete the application due to the lack of compressed air supply) are indicators of the compressor size being too small.

3. Not paying attention to air quality requirements. Different applications have different air quality requirements. such as medical or pharmaceutical industries, require 100% oil-free air; others, such as general manufacturing, may not have such strict air quality requirements. We recommend that you discuss your process with a local compressed air expert-they will be able to guide you on whether an oil-free air compressor or an oil-injected air compressor is best, and what types of filtration may be required for your process.

4. Underestimate the life cycle cost of the compressor. The life cycle cost of an air compressor usually considers three factors: initial investment, life cycle maintenance costs, and life cycle energy costs. When making your selection, remember that 80% of the compressor life cycle cost is attributable to energy consumption; this means that when determining the cost of operating your compressor over its entire life cycle, the energy efficiency of the machine you choose very important.

5. Choose the wrong service provider. Choosing your compressed air service and parts supplier is one of the most important decisions you will make in an air compressor system. You need a supplier who can provide OEM parts, regular maintenance and emergency services, and a supplier with a good reputation in the compressed air field.
