Best Rotary Screw Air Compressor Reviews

1. ingersoll rand UP6-7.5-125 rotary screw air compressor

Ingersoll Rand UP6-7.5-125 is one of the best screw compressors out there. For one thing, it’s a machine from such a reputable brand.

The highlighting component of this rotary air compressor would be its motor. It has a 7.5 HP motor that is extremely quiet. You might forget there is an air compressor in the room. The tank can hold 80 gallons of air. This means that it can be used for long hours with minimal strain on the motor.

Air is delivered at a running power of 28 CFM at 90 PSI. The maximum working pressure is at 125 PSI. The rotary air compressor is electric and works at 230 volts. It is also a single phase. This means that it only has one cylinder. This makes it more suitable for smaller applications like use in garages, workshops, and small shops.

One thing I liked about this rotary screw compressor is that it has an aftercooler. The machine can cool down discharge air temperatures on its own. Besides, it has the auto start and auto stop feature. With this, it can work correctly without the need for you to be there or keep checking.

An air compressor consumes a lot of energy, and this can cost you a fortune in the long run. This is a highly recommended rotary air compressor in terms of energy efficiency. It has energy controls that help to reduce the overall amount of energy used.

On the other hand, you will have to consider if mobility is a factor. This machine lacks wheels, and it’s also quite heavy. Moving it around may be a huge challenge. Similarly, the maintenance kit is sold separately from the product. It can be an additional cost to you.

Things To Consider Before Buying The Best Rotary Screw Air Compressor

A rotary screw air compressor is like a lifetime investment. When you decide to buy it, it’s in your best interest to get the best in the market. There are several things that you have to keep in mind when purchasing a rotary screw air compressor. Here is what to look out for.

The Price

The price of an item is the first thing we look at when shopping. Rotary screw air compressors have various price tags. Typically, the higher the price, the more advanced the machine is. Therefore, ask yourself what your needs are and if the model you choose will work for you.

The Horsepower

This is another crucial factor to consider. The horsepower is generally the strength of the engine. In this case, you have to determine your compressed air requirements. Don’t just go for a rotary air compressor with higher horsepower.

Many people think that these are better than the ones with the lesser horsepower. The truth is if you buy an air compressor with high horsepower, you will only add to your costs. This is especially if the additional horsepower is not needed. Determine your needs first.

Airflow (CFM)

CFM is the rate of airflow in the air compressor. It’s one factor that you can’t leave out when buying a rotary air compressor. When using more than one tool simultaneously, then you have to get a machine with a high CFM.

On the other hand, some air tools have a low CFM requirement. In this case, you may not need a model with a very high CFM. Ensure that the tools will function well with the CFM of the model you purchase.

Integrated Air Dryers And Filters

Some rotary screw compressors have additional features that include an air dryer and an air filter at times. Compressed air may have some moisture in it. The air dryer works to get rid of this moisture so that you only have dry air in your machine.

Besides, there is always some dirt or oil in the air. If these impurities keep accumulating in your device, they reduce its performance. An air filter helps to ensure that your air compressor gives an optimum performance.
You will have to keep in mind that these features may add to your energy costs.

Variable Speed Drive

A variable speed drive air compressor can significantly help you to save energy. The energy costs of running an air compressor may go up to millions of dollars. This makes the operation costs expensive. Consider just how much you can save on energy with the use of a VSD air compressor.

There are two things to consider with variable speed drive air compressors. If it runs entirely at a speed of 90-100%, it consumes a lot of energy. Also, if the machine runs at a slow speed of 10-20%, it’s not worth it. It’s too big for your applications, and you don’t need the VSD feature.

The variable speed feature is convenient when the air compressor runs at a speed of 50-80%. In this way, you can save a lot of money on energy.

Belt Drive Or Direct Drive

There are two types of compressors. There is the belt is driven and the one that runs without it. In my opinion, direct-drive machines are better than belt-driven ones.

A belt-driven air compressor calls for more maintenance requirements. The belts used may wear out, and you have to replace them from time to time. Also, they accumulate dust quickly. If less maintenance is vital to you, then the best fit for you is a direct drive machine.

After-cooler

A rotary air compressor can either have an aftercooler or not. I would recommend that you go for a model that has an aftercooler. It reduces the temperatures of the compressed air coming out of the air compressor. You wouldn’t want air that is 80 degrees hot getting into your air tools.

Furthermore, the aftercooler does more than to cool down compressed air temperatures. It helps to get rid of water from the compressed air. With no aftercooler, moisture will be condensing in your air tools and air piping system.

The Size Of The Tank

The size of the container is determined by the tools you will be using with the air compressor. In case you are using the air compressor continuously for long hours, a bigger tank should be your priority. On the other hand, if it’s only used intermittently, then a smaller container will do.

Always go for an air compressor with a size-able tank. A small container can strain the motor. Similarly, if the air tank is small, the compressed air will not have enough time to cool down. Hot compressed air has the potential to damage the piping system, air tools, and the compressor itself.

Portability And Space

Portability largely depends on the size of the rotary air compressor. Consider the kind of work you need for the air compressor. Most of the rotary screw air compressors don’t have wheels.

Even so, you can lift it from one place to the next if it’s not too heavy. Some of them are very heavy and only have to be operated from one area.

Final Verdict

In the market, you will get a wide variety of rotary air compressors. However, the best and most convenient ones are the rotary screw air compressors. There is no noise, making the working environment conducive.

Furthermore, they are engineered to operate continuously day and night seven days a week. They are durable and can serve you for many years. Whether you want one for small applications or industrial uses, there is always a suitable rotary air compressor.

Rotary air compressors are the kind of machines that you can rely on it. You have all the details on the best models out there — all you have to pick the one that will deliver the best and satisfy all your needs.
