HOW TO Get THE Best Pneumatic COMPRESSOR
You may or may not already be aware that not all air compressors are used for all jobs! They vary in both size and of course their power level. The best way to estimate what you will need is to take a careful look at the power requirements of any of the air tools you plan on using. Then its a simple matter of choosing one that is slightly more powerful than youll need so that you have the ability to purchase an air tool that needs a bit higher power level.
For example, one common air tool is the rotary screw compressor. When looking for a rotary screw compressor, you are faced with an array of choices. If you want a powerful screw compressor, don't choose a cheap one. Those are only good for occasionally pumping up your tires with air.
Air compressors are sometimes rated by horsepower or hp. Dont be swayed by the hp listing. It all depends on how much power it draws. Often the hp listed is inflated.
Instead, you should look at the PSI, which stands for Pounds per Square Inch. Generally, youll require 90 PSI for most air tools. However, an air compressor listed at 125 to 135 PSI will not run that air tool properly. You see, the PSI is the shut-off pressure, and even if an air compressor shuts off at 100 PSI, this does not take into account something called pressure loss in the line! Thus, to work at peak efficiency with 90 PSI tools, you should really consider a two stage pressure shut off compressor, that shuts off the first stage at the 90 PSI, but the second stage wont shut off until it reaches 175 PSI.
Also think about cubic feet per minute (CFM). For most air tools you'll find in the store today, a CFM of 4 to 6 is common. This will make your life easier because at 90 PSI you should be getting exactly 3 to 4 HP. The CFM is a measurement of how much air moves through the system.
Another thing of import, depending on how you plan to use the compressor, it's tank size. A regular pump and motor with the normal 30 gallon tank is just fine if what you are doing only needs you to use short bursts. But for heavy use, you'll be much better off using a smaller tank with a significantly stronger motor and pump, of course with attentive consideration to the stored air in the tank.
Because of this you may see professional contractors running multiple air tools at the same time, with the knowledge that using a compressor with a rating of 150 PSI is a better choice for long-term continual use.
Truck mounted compressors differ from portable ones because they use the truck itself as a source of power. Of course a problem with this is a fact that the truck has to keep running to keep the compressor going. If you need to keep the compressor in use for long periods of time, the best choice is a compressor that is deck mounted. Deck mounted compressors are similar to truck mounted ones in that they sit on removable beds for the truck. This makes it feasible to let the compressor stay at the worksite instead of forcing you to lug it every day.
Also you can find compressors that are electrically and gas powered. If you think you're going to be working on a site that does not have electricity, then go with a gas powered compressor. - 21396
