Here’s a list of questions you will need to answer.
What application do you need compressed air for? How much air flow and pressure do you require? Do you need clean air or dry air or does air quality not matter much? Will your industrial compressor run continuously or only part of the time? Do you need a quiet workfloor companion or is noise not a factor in a separate compressor room? What type of maintenance interval are you looking for? Do you want to invest more initially and save later with low energy costs? Do you need the same amount of compressed air or does your demand fluctuate? Are you planning to expand any time soon?
Once you know the answers to these questions, the selection of the right industrial compressor is often very easy.
Next you have to figure out your air quality needs. Some applications require dry air while others call for particularly clean air. For the former, you can integrate a dryer. For the latter, you have to decide whether an oil-injected compressor with additional filtration suffices or if an oil-free compressor is required.
Oil-injected compressors are usually the right selection when the compressed air they produce does not have to be particularly clean, e.g. for inflating tires or powering tools.
An oil-free industrial compressor is generally the right choice for when the air purity has to be absolute, e.g. in the food and pharmaceutical industries where the compressed air comes in touch with an end product.
The last decision depends on whether your air demand is consistent or whether it fluctuates. If it is the former, then a fixed speed air compressor is likely the correct solution. However, if demand fluctuates, for example in a business that operates with a lighter crew on weekends, then a fixed speed compressor is an inefficient choice and a variable speed compressor is the way to go as an energy-efficient alternative.
A VSD+ air compressor from Atlas Copco, for example, can reduce the energy costs by 50%. And that adds up quickly considering that these costs make up more than 70% of the total cost of ownership of a generator across its service life.
Finally, if you are still not sure what type of compressor is right for you, an Atlas Copco representative will gladly assist you.
