Air compressors have grown more and more common over the years for a variety of purposes – much like much other electronic equipment. An air compressor is of use to many different professionals such as contractors, automotive technicians, heavy-duty mechanics and even serious hobbyists. It is important to have an air compressor that can keep up with the kind of purposes it is intended to be used for. We understand that a lot of factors go into buying an air compressor, and it can be challenging in the current market to take a final decision regarding what the best budget air compressor might be. This is where we come in – with our extensive research and painstaking analysis, to help you make that decision as efficiently as possible. We have finalized a list of factors that are crucial in determining how you can choose a good sturdy efficient product. without having to sacrifice your budgetary constraints. Our aim is not to just tell you what we think is best, but rather to educate you on the factors that should govern your choice so that ultimately, you can take the decision as a rational informed consumer.

Factors To Consider In Choosing Best Budget Air Compressor

Horsepower (HP)

This constitutes one of the most if not the most important factor(s) that should be considered while choosing a compressor. It is really beneficial in determining what size of compressor would be best for you. The problem however is that in recent years, the scourge of marketing has sought to exaggerate this factor to expand the sales of big-box stores. In this regard, the horsepower ratings of industrial compressors are a lot more reliable. and therefore it is generally the case that a 3 HP industrial compressor is almost 3 times more expensive and large when compared to a 5 HP hobby-type compressor.

One of the best ways to judge whether or not a compressor’s HP is overrated, is to check the amount of electrical power that is used up in running the machine. In most cases, almost all overrated hobby-type compressors run on a normal 15 amp 110 volt circuit, which in reality, is only capable of running about 2 HP. In contrast, a true 5 HP compressor draws about 24 amps on 220 volt circuit (single phase power).
It should also be noted that gas engine HP is rated differently as compared to an electric motor HP. To cite an example of this, an industrial 5 HP electric compressor will take as much air as a 10 HP gas compressor.

Air Pressure (PSI)

The unit of measurement for air pressure is generally in pounds per square inch or PSI. When it comes to most average run-of-the-mill air tools, they require around 90 PSI to run on decent capacity. However, if you’re thinking of maintaining 90 PSI at the tool, a compressor with a much higher shut-off pressure is required. Most industrial compressors are two-stage. This means that they build up to shut-off pressure in two different stages.

The first stage is usually responsible for building up to about 90 PSI whereas the second stage usually builds to around 175 PSI. For cases of hobby compressors or small commercial duty compressors, they are usually single stage and shut off at 125-135 PSI. Although this may feel more than adequate air pressure, it could be deceiving. Once the pressure drop from the hose and couplers is considered, the PSI may get reduced to somewhere in and around 100 and there might not be enough pressure at the tool.

Cubic Feet Per Minute (CFM)

This particular unit is used to measure the volume of air that a compressor produces. It is important to mention that air tools require a certain volume of air to keep themselves running. It is perfectly natural to see several different CFM ratings at different levels of pressure on a compressor. It also isn’t uncommon to see a high rating on a displacement CFM. This is generally a calculated rating based on the size and speed of the compressor pump.

The value and use of this rating are limited because it is at 0 pressure and does not consider the inefficiencies of the pump. Most tools can generally run efficiently at a pressure-level of 90 PSI – and this is usually the most important CFI rating on smaller compressors. Consumers should be vigilant when it comes to CFM ratings, as these can also be exaggerated as a marketing tactic much like HP levels. It is prudent to look for at least 3-4 CFM per real HP at 90 PSI.

Air Compressor Tank Size

The size of the air compressor tank is important and is vital to the compressor’s performance. Since the compressor tank is only responsible for storing and not producing air, it makes a lot more sense to focus on the greater size of the pump and motor. If an individual is able to produce as much air as required, then the question of storing the air in small or larger spaces becomes largely redundant.

It should be kept in mind though, that in certain situations it is smart to save money by getting a smaller compressor with a large tank if the user plans to use air intermittently. For example, in a situation where a compressor is producing 10 CFM continuously, 20 CFM can be taken out of the tank for half the time. For purposes of running a 1’’ impact wrench (around 20 CFM intermittently), the user might have enough air in the tank to perform this function. Using this mechanism, the compressor is able to build pressure until the user is required to repeat the job.

However, there are certain cases where producing as much air as is possible could actually be beneficial. For instance, when a user intends to run a tool steady such as a sander, this principle should be taken into account. Smaller tanks generally have a greater flexibility in terms of the portability factor, whereas larger tanks do not store and start as quickly but they cool the air better. A lot of people make the mistake of thinking that a large tank makes the compressor run less but this is a misconception. A compressor with a larger tank runs the same as that with a smaller tank, the only difference being that the former usually starts and stops less. The unit of measurement for tank size is usually US gallons.

Single-stage/Two-stage air compressors

The number of cylinders present in the single-stage air compressors is usually one or more, with each cylinder pumping air directly into the tank. Two-stage tanks are usually equipped with a minimum two cylinders and air passes through two consequent cylinders before ending up in the tank. The passage through which air moves in a two-stage compressor usually involves a cooling tube into the smaller second-stage cylinder at about 90 PSI and then eventually to the tanka at about 175 PSI.

For those rare applications that require a high level of pressure, two-stage compressors are very much useful. Another myth that needs to be taken down, is that two-stage compressors are better than their counterparts as a general rule. The truth is, however, that most industrial quality 5 HP compressors are two-stage, and they are better mainly because they are of a higher standard pertaining to industrial quality levels.

Direct drive or Belt Drive, Oil or Less Oil

Good compressors could be of both the Direct Drive or Belt Drive varieties. However, it has been found upon analysis, that most of the direct drive variants are of a lower quality, essentially because these are usually designed to keep the cost down for big-box stores.
Motor shafts are usually present for connecting direct drive compressors typically spinning at a rate of 1725 or 3450 RPM. Barring a few exceptions, most good quality direct-drive compressors generally have low RPM. The purpose for designing certain compressors that spin twice as fast is to get more air out of the compressors.

The problem is that these compressors usually have a much lower life expectancy and a lot of unwanted noise. There are still a few manufacturers who make low RPM direct drive compressors in smaller sizes. These can be a great option for finishing carpenters and other types of tasks which require greater levels of portability and quietness. Certain direct-drive compressors are also oil-free, which has used in certain applications such as breathing air or aeration. It is advisable to try and avoid high-speed oil-free compressors, however, if they are low RPM and have the right characteristics of design, they can have a much longer life.

Many European manufacturers are famous for making high-quality direct-drive oil-lubricated compressors. These are ideal for work related to the construction industry, owing to matters of portability and compactness. In recent times, certain Chinese variants similar to their European counterparts have sprung up across markets and like other types of Chinese manufactured products, some of them are good while others are not.

For purposes of higher air volume, and in cases where not much mobility or portability is required, direct-drive oil lubricated compressors should be the ideal choice. But the buyer is advised to be vigilant as there are are some high-speed aluminum pumps with a low life expectancy that are built for a low price much like their direct-drive counterparts. Belt-drive compressors are usually equipped with a pump that spins much slower than the motor, allowing for more efficiency and less wear and tear.

Many belt-drive compressors have a splash lubrication mechanism that enables it to splash oil in and around the compressor crankcase. For a value for money deal, consumers should consider getting a belt-drive oil lubricated compressor and avoid the high-speed, noise and oil-less ones.

Duty Cycle

Knowledge of the duty cycle is essential while purchasing a compressor. The duty cycle is expressed as a percentage and indicates the number of minutes the compressor is allowed to run out of a ten minute period. Low-quality hobby compressors usually have a 50 % duty cycle meaning that it should not be run for more than 5 minutes within a ten minute period. Exceeding the duty cycle overheats the pump and casts doubts on its long-term viability. On the other hand, most industrial compressors can be run continuously owing to their higher level of the duty cycle. It is prudent to spend a little more money to get a much a greater value with a compressor that has a higher duty cycle.

Moisture problems

Greater activity of the compressor usually leads to greater heating of the device and that in turn causes greater moisture problems. Getting a bigger compressor is useful as it does not overheat easily and can work for longer hours before the heating becomes a problem. Humidity is also a factor which can aggravate moisture problems. A common misconception is that the water in the airlines can be reduced by draining the tank of the compressor. It is important to make sure that the user does everything possible to cool the air before it gets into the moisture trap.

Life Expectancy

It is important to consider this factor with clarity, before purchasing any kind of compressor. The buyer should try and get an understanding of the product’s life expectancy from the seller and in case the seller doesn’t know, it is prudent to call up the manufacturer. For every dollar spent in getting a bigger good quality industrial compressor, 2-3 dollars may be saved in the long run. The best way to go about purchasing the best budget air compressor 2018 is for you to simply consider how much the product costs per hour of life expectancy.

Size

Although compressors may be large or small, it has generally been observed that larger compressors are favored a lot more because of their industry-standards. It has also been observed that most automotive air tools require around 10 CFM at 90 PSI to keep them going. As a general principle, it is overall a better option to have 2 and a half HP for each automotive tool. However, in cases of industrial air tools, they require a lot more air as opposed to the automotive ones.
