Compressed air has long been used in many industries and as you would expect, there is quite an array of compressor types, which can make choosing a bit of a challenge. In this article, we outline some of the popular air compressor types, their inner workings and uses.
Positive displacement compressors
This is a class of compressors that generate energy via displacement, using a range of internal mechanisms. A simple way to describe the action is that air is brought into the device, which is gradually compressed to produce energy (horsepower) that can be released when needed.
- Rotary screw compressor – The rotary screw compressor you can find at https://www.domnickhunterrl.com/ is one example of positive displacement that can run with or without oil. Ideal for construction sites where compressed air power tools are used, large units can provide all the compressed air you require and maintenance is easy, as there are not many moving parts. The most popular type of air compressor, with both dry and oil versions; check with the supplier regarding which is suitable for your needs. The supplier also offers servicing to ensure the equipment is always ready for work.
- Reciprocating compressor – This method uses pistons and cylinders to compress air and it is not designed for heavy duty use. Typically found in home workshops or small engineering plants, a reciprocating compressor can have a single or multiple stages, when high compression is required. This machine has more moving parts and needs to be oil lubricated and serviced at regular intervals. Once the required PSI is reached, the compressor turns off and as you use the compressed air in the reservoir, the pistons kick in once more to maintain the pressure. This type of compressor should not be left on for long periods.
The dynamic compressor generates power by sucking in air using rotating blades, which is then forced into a storage cavity. There are two main types:
- Axial compressor – Extremely efficient and very costly, these are normally used on ships and aircraft and would not be found in regular industry.
- Centrifugal compressor – The multi-stage process generates very high pressures and this type of compressor would be found at large manufacturing plants.
Both of the above require regular maintenance to ensure high performance and if you are looking for a Thai supplier of air compressors, Google will take you to the leading company that has all the solutions. Here are a few tips on how to make your business stand out from the crowd.
Choosing the right type of air compressor
The best approach is to contact a leading supplier of industrial air compressors, as they would have a wealth of hands-on experience helping businesses select air compressors and are always happy to advise on every aspect of compressed air. An online search is the best place to start your quest for an air compressor supplier.
The Thai Ministry of Industry regulates the standards of equipment used in plants and factories across the Kingdom and you do need to read the safety information when using air compressors.
