Finding a good 80 gallon air compressor is a bit difficult, due to all the choices out there. There are a number of compressors on the market and typically range from $1,100.00 to $3,000.00 depending on manufacturer, make and model, and they all have their positives and negatives. Here are some things you need to consider in order to buy the right one for you.
80 gallon air compressors are normally used in applications such as automotive repair and body shops to light manufacturing applications, they typically range in horsepower from 5hp to 7.5hp and are usually 2 stage reciprocating or screw type air compressors, the screw type being the more expensive typically used in light manufacturing.
Know what you will using it for.
This will help you determine the amount of psi (pounds per square inch) and cfm (cubic feet per minute) you will require from your compressor. Here are 3 variables that will be impacted by your specific needs:
PSI (pounds per square inch)
The PSI output of your chosen air compressor should meet or exceed the requirements of the device it will be operating with the highest psi demand. Be sure to check the manufacturer specifications on all the devices you will be operating. Also, knowing your psi demands will help you determine if it is a single stage (125 -135 psi) or a double stage (175 psi) air compressor that you will be requiring.
CFM (cubic feet per minute)
The cfm of a particular air compressor is the measure of air volume the unit is capable of putting out, to determine what you will require total the cfm of the devices you will be simultaneously operating to make sure the compressor can produce sufficiant cfm.
HP (horse power)
Motor horsepower has a direct affect on the CFM rating of a compressor; more often, the greater the horsepower the more air flow or cubic feet per minute the compressor can produce. Know your CFM and PSI so that you can determine horsepower. Following these requirements will help you choose an efficient and affordable air compressorsuitable for your needs.
If it does not have enough power, then the pump will have to cycle very frequently, and will soon cause premature pump or motor failure. Even if you are just a tiny shop owner and only need the compressor for simple air tools like air ratchets or impact tools, you need a compressor with a sufficiant amount of psi, cfm and horsepower. This will allow the tank to recharge it self fast enough, and give enough pressure to use the tool and run it effectively.
Having enough psi, cfm and horsepower are the main considerations when making such a purchase. If you do not have enough, then the unit will run out of air pressure very quickly, and you will constantly be waiting while the compressor recharges itself. Therefore, having sufficient amount of these 3 requirements with your 80 gallon air compressor can really speed up your production time, and help your work go faster.
An 80 gallon air compressor can be a pretty expensive investment, It is wise to choose a top quality brand compressor that offers at least a 2 year warranty and backs their product with excellent customer serviec for as long as you own your compressor.
