subject: Air Compressor Purchasing Tips [print this page] Need to find the best air compressor? Before choosing any compressor to get, knowing the compressors uses will make sure that this machine is capable of doing the desired task. Buying a compressor that is a little too small is likely to waste precious time or just flat out won't do the job. Buying an air compressor that will be much too big will waste precious resources, especially your hard earned money.
It is actually worth mentioning that the cost of a compressor is not set just on the up front purchase price of your unit. The cost of something really needs to be based on the total price over many years of time or the life of the product. Low-cost machines are made to be disposable.
A few of the questions to get resolved are:
* What is the highest necessary operating pressure?
This will determine if a Single Stage or Two Stage compressor is actually necessary.
What is the maximum necessary air flow usage?
Air flow is measured in cubic feet per minute or CFM. To figure out what you require, tally up all of the air tools that will be used in unison. When looking at the compressor, add approximately 25% to the set CFM amount. That should provide a decent buffer against unknown or out of the ordinary compressor use.
Don t just tally up each of the air tools that will be utilized through day at work because this will produce an inflated CFM amount and necessitate the acquisition of an overly big compressor.
* Does the machine need to be portable or fixed?
Determine whether or not the item would need to be moved all over your shop or construction site on a regular basis or if it is a stationary tool. This tends to help in determining other factors like the size and weight. High pressures and volumes require the item to generally be bigger in size plus heavier in lbs because horsepower specifications, pumps, chassis structure, power features, and so forth must be bigger to accommodate these types of increases.
* What sort of drive system is essential?
Knowing the situation where the compressor could be employed in will determine what kind of drive system the system needs. In the event that there is certainly electricity available, then the drive system should really be an electric motor due to the fact they are a lot less expensive to buy and run as well as need considerably less general maintenance. If power isn't always made available then the convenience of a gasoline engine driven compressor will probably be the way to go. They give you the best in portability and work area versatility.
* Just what receiver tank size will likely be desirable?
How large the compressor reservoir, usually measured in gallons, will be influenced by the general kind of usage. In case the usage is within concise swift concentrated spurts, for example an air nailer, then a reduced tank volume works extremely well. Whenever the equipment is to endure long stretches of consumption, say for example board sander or impact wrench, a larger tank size will be vital.
