Undeniably, air compressors are very useful for everyday use. But to get the best out of these machines, you need to choose the perfect machine. And to make the right selection you have to be aware of certain factors.
The airflow’s rate of an air compressor – The airflow’s rate of every air compressor is measured by CFM that is cubic-per-feet-minute. You must check the airflow’s rate while purchasing a petrol air compressor. Such a number can be expressed in another way known as pounds per square inch or PSI. When you are thinking about the CFM, you ought to consider that how you are using the air compressor. It is suggested to buy an air compressor for household use whose CFM’s number is a bit higher and not lower.
Determine the kind of motor – There are distinct kinds of air compressors present in various stores. An air compressor is of many types: gas, electric, petroleum, diesel air compressor and so on. Some places may have higher electricity rates, while in other places the gas prices are reasonable. An electrical air compressor is ideal in those places, where the cost of gasoline is high. Suppose you live in a place, where a power cut happens frequently and in this case only an air compressor powered by gas is good. Additionally, lubricated compressors lasts for a long span of time. But in reality these kinds of compressors spray only a little proportion of oil and one have to change the oil many times. If an individual wishes to have the compressor for doing spray painting or other things, which need a clear surface, such as pressure cleaning, then he must not purchase a compressor powered by oil.
Think about the tank size – Suppose you only require an air compressor for a short span of time, then a small tank is a good choice. But if you are working too long with the compressor, then you must have a big sized tank. Generally, all the sizes of the tanks are measured in gallons.
Horsepower is the second most important feature – Actually, horsepower is the engine’s strength that is driving the compressor. All the air compressors should have a definite horsepower and the buyers ought to purchase those compressors along with horsepower that fulfills the requirement of the buyers. But, it must be kept in mind that each and every person must pay more attention to CFM and less attention to horsepower.
