When we choose an air compressor, will we encounter such a problem: It seems that only through various compressor technologies, sizes and other specifications are not enough to help us choose a screw air compressor suitable for our industry. The following are a few common mistakes when choosing a screw air compressor:

1. Choosing the wrong compressor technology. There is a wide variety of air compression technologies on the compressor market, from rotary screw and piston (reciprocating) compressors to scroll and centrifugal compressors, and the variety of compressors can be confusing when making a choice .

So before making a decision, the following points may help you: Screw air compressors are ideal for businesses looking for a compressor with low noise and low maintenance requirements, as well as those that require longer duty cycles and longer run times application. Piston compressors are ideal for businesses with lower air volume requirements, as initial compressor cost is more important and the load rate requirements for day-to-day operation are lower. Some customers have high requirements on the floor area, so they are also an ideal choice for this part of customers. Scroll compressors are ideal for applications in R&D, universities, breweries, dental offices, hospitals and more. These compressors run very quietly and provide oil-free air.Choose the wrong compressor size.

2. Choosing a compressor doesn’t lend itself to a “one size fits all” approach. Knowing the exact operating pressure and compressed air volume flow for your process is key; in addition, you should consider potential business or facility expansion. If you choose a compressor that is too large, it can lead to huge energy bills, mainly due to the peak energy generated when the compressor starts up and unloading waste. Excessive start/stop cycling can also lead to motor burning and other potential mechanical failures. (If the compressor you choose is too small, the flow rate cannot meet the actual demand, and the pressure will drop, causing the task to be unable to be completed (due to insufficient compressed air supply).

3. Not clear about the air quality requirements of the industry. Different industry applications have different requirements for air quality. For example, the general manufacturing industry may not have strict air quality requirements. We recommend that you discuss your type of industry with our dedicated compressed air specialists so we can give you solid advice, such as oil-free or oil-injected air compressors, and what filters may be required.

4. Underestimate the life cycle cost of the compressor. The life cycle cost of a compressor usually considers four factors: initial investment, installation cost, lifetime maintenance cost and lifetime energy cost. When choosing, keep in mind that 80% of a compressor’s life cycle cost is due to energy consumption; this means that the energy efficiency of the machine chosen is very important in determining how much the compressor will cost to operate over its lifetime.
