Compressor typeThere are basically 3 types of reciprocating air compressors:Single stage compressorsTwo stage compressorsTwin compressorsSingle stage units compress the air in one stroke, from ambient to end pressure. They typically go up to 20 CFM (cubic foot per minute) at a pressure of 125 psiFor more power, you will need a two stage compressor. A two stage compressor uses two stages to compress the air to the end pressure. This means your compressor will have two cylinders/pistons.The big cylinder is the low pressure stage, while the small cylinder is the high stage. In between the stages the air is cooled.Two stage air compressors go up to about 50 CFM capacity at about 175 psi.Whether you need a single or two stage compressor ultimately depends on the amount of capacity (cubic foot per minute) you need.2. Capacity and pressureThe capacity (CFM) and the pressure of the air compressor are the two most important specifications.To find out the capacity that you need, simply add up the air consumption of all the air tools that you will use.Small tools like nailers use only a little air, while big tools like sanders and grinder use lots of compressed air!To find out the pressure that you need, check again the specifications of the air tools that you plan to use. Look at capacity (CFM) and pressure (psi).4. Electrical connectionsYou wouldn’t be the first happy new compressor owner that comes home with an air compressor that he is unable to wire up!Know the voltage that you have at home. Know the maximum current that your wiring can handle. Do you have single phase or 3 phase power?Installing extra electrical wiring (or even having 3 phase power installed at your home!) can be more expensive than the air compressor itself!5. NoiseDo you plan to install the compressor inside or outside?A reciprocating compressor makes a lot of noise. Always check the noise level of the compressor before buying one. If you are buying a compressor in a shop, ask them to run it, so you can hear what is sounds like.To reduce the noise, you can make an enclosure around the compressor. Make sure you add enough ventilation holes (and a fan if necessary). An air compressor creates a lot of heat, so adequate cooling is required!6. Tank sizeMost reciprocating compressors come with a 40 – 80 gallon tank, which is fine.A larger tank size is always better. A bigger tank means that there is a bigger compressed air buffer.A bigger compressed air buffer is useful when you use big tools that use more air than the capacity of your compressor. Pressure will drop more slowly with a bigger air tank.7. Compressed air filtersHow clean do you need your compressed air?Compressed air is hot, wet and dirty. Depending on your application, you need to filter it and remove water and oil.If you use compressed air for paint-spraying, you don’t want oil, water or dust in your compressed air, the air needs to be very clean.If you only use it for powering air tools, you don’t want water in your compressed air but you don’t really care about oil.There are filters available to remove water (droplets), oil, and dust. For even dryer compressed air, you need to get a compressed air dryer.8. To watch comparable air compressor pulley products we provide visit this site.
