The function of every air compressor is the same- i.e to increase the air pressure and reduce the volume of the element (gas or air). Typically, the brand may be different, but the actual function remains the same. So, what to look for when purchasing an air compressor? Well, you look for the brand that helps you to save costs depending on the sector they are used in.
The buyer’s guide
Unless you are an expert, it is best to browse for information and then choose the kind of air compressor you need. An air compressor may look like a simple machine to operate, but the tool comes in three grades- industrial grade is different from the consumer grade which is simple to use. In case multiple tools need to be managed then the grade of air compressor is different. Look for a contractor grade or commercial grade before making the decision to buy.
When you work on location, there is bound to be some wear and tear. The machine should be strong enough to cater to professional demands. These kind of air compressors are built keeping in mind the professionals who will use them. Hence, they need to be strong to withstand the severities. The machines are large, portable, wheeled, or even attached to a vehicle. On location they can power the nail-guns and also power road repair tools.
They are more powerful and perfect heavy-duty machines. The latest ones on the market come with advanced technology, built, and design. They can be useful in various shops of auto body manufacturers. They are even useful for applications like powering machinery in oil rigs or roller coasters.
Understand compressor’s usage
Since, we have learnt about the two important grades we also need to understand what to look for when purchasing an air compressor. Then only you can buy the machine. A large one will waste the resources and a smaller one will be equally useless. The price is devised on the overall cost. It also covers the warranty of the product. You may choose a disposable unit at your own risk.
Ask the following questions before purchase:
- Do you know the minimum operating pressure of the machine? Then you will know if a single or two-stage unit is required.
- Are you aware of the maximum CFM usage? You will need to know the number of air tools you have. Add 30% to determine the CFM figure. It is required to buffer some unknown utilization of the unit. Don’t inflate the usage figures. Speak to the dealer before buying.
- You will need to know if the unit will be portable or stationary.
- There are three kinds of drivers-electric, motor or gasoline. Check as to which will suit your purpose?
- An absolute important question is the receiver tank set size. It is measured in gallons. Overall, usage should determine this query.
More than anything else, choose the right manufacturer for the unit.
