Do I need an oil-lubricated or oil-free compressor?
There are different air purity classes that compressed air can fall into according to the International Organisation for Standardisation (IS0). It is important to consider if your organisation requires a specific class of air before you choose which type of compressor to purchase.
Food and beverage industries, as well as pharmaceutical and chemical, will often require ISO Class 0 air quality. This is the cleanest standard of compressed air possible and requires 100% air purity. If clean air is required for your application, an oil-free compressor will always be the most efficient choice. Although upfront costs may be more than a traditional lubricated compressor, you will have the assurance of always being able to guarantee a clean output of contaminant and silicone-free air.
If your compressed air installation will be for general use and not require Class 0 clean air, then a lubricated compressor will be the more economical choice for you. Lubricated compressors are extremely popular and are the most common type of compressor in use within industrial sectors. They are robust, reliable and high performing machines.
What size compressor do I need?
The next thing to consider is the size of the compressor. You should consider your individual air requirements and choose a size based on this. Choosing a compressor too small could cause issues when demand is high, resulting in problems with production. However, a compressor too large for your operation could lead to wasted energy and a higher cost of ownership.
It is also important to understand your flow and pressure requirements. You will need to purchase a machine that has enough pressure to achieve the performance you require for your application. You will need to consider the amount of compressed air flow (CFM) you will need at a specific pressure (PSI) in order for the application process to run smoothly. All of these factors will affect the size of the compressor you choose.
What type of compressor do I need?
There are many different types of compressor technology available from reciprocating piston compressors to rotary screw compressors. To choose a compressor technology type, you should again look at your demand. Consider how many hours a year you will require your compressor to operate, if you need a constant or intermittent supply of air and if there is ever going to be a fluctuation in demand. All of these factors will affect which design of compressor you choose as each compressor has a unique set of features and benefits.
Steps to take before you purchase
If you are still unsure, you may consider asking a professional to conduct an air audit. This can help you to assess your air output demand and provide you with some insightful ways to improve the overall efficiency of your operation.

Industrial Air Compressor Applications
Industrial air compressors are the work-horse behind many products and processes, some that you may not even realise! From food packaging and processing to coating tablets and spray painting cars, the uses of industrial compressed air are multifarious.
Some of the most common industries and applications where compressed air is used are:
Used for car and engine assembly as well as to power AI robots and create clean finishes with spray paint.
Food, Beverage and Brewing
Used during the production of brewed products as well as for food packing, processing and transporting.
Chemical and Petrochemical
Used for handling hazardous materials as well a nitrogen generation and process air for direct contact with the product.
Used widely within the industrial manufacturing industry for a variety of uses including air-operated tools and equipment, access lifts and shot blasting, to name a few.
Used for cleaning expensive electronic equipment such as PCB boards and also for pick and place machines.
Oil and Gases
Common applications include petroleum refining, petrochemical synthesis, pipeline transportation and gas injection.
Marine and Military
Compressed air provides power for many ship functions in marine applications and is sometimes used for simulators and shooting range targets in the military.
Medical and Dental
A variety of applications require compressed air within the medical and dental industry including respiratory equipment, powering surgical or dental equipment and for sterilisation.
The pharmaceutical industry relies on compressed air for packaging and sealing medication, fluid pumps to move liquid products and for air knives which can be used to cut products.
Compressed air can be used in the process of making high-quality materials during jet weaving, spinning, texturizing and dyeing.
Gardner Denver has invested 16 million Euros in the Simmern "Centre of Excellence" plant in Germany, where its industrial air compressors are manufactured.
