Small rotary screw air compressors are still relatively large for compressor machinery. You should expect a tank size of around 60 to 120 gallons.
These air compressors are still seen as industrial tools, but smaller sizes make them great for DIY enthusiasts or low need workers.
Today, we will explain what a Rotary Screw Air Compressor is, what to look for when you’re buying one, and the best small version on the market!

What Is A Rotary Screw Air Compressor?
Rotary screw air compressors have rotating screws-like mechanics, which press air until it is so tightly packed that it can create force. They move in a positive displacement mechanism instead of piston compressors.
Rotary screw air compressors have two rotating interweaved helix screws. As they rotate with each other, they capture air in the pockets between the helix shapes.
When the air gets trapped, it is pushed until it gets smaller and smaller, traveling down the axis of the screw.
The air is then released (or discharged) from the opposite end of the helix screws. At this point, it will have been pushed and reduced so much that the release will cause the air to rush out in force.

Buyer’s Guide
When buying a rotary screw air compressor, there are 4 factors you need to consider. They are the horsepower, the airflow (also known as CFM), the integrated filters along with the air dryers, and lastly, the electrical phase.
These concepts might seem wildly technical, but we will explain what you should be looking for so when you buy your compressor, you will feel confident in your purchase!
Rotary Screw Air Compressor and Horsepower
Although the screw helix mechanism creates compressed air, it’s the engine that powers the strength of the compressing, and therefore the amount of pressure you can make.
Depending on your needs, you may not require high horsepower. For example, if you need your compressor to lift 400lbs at a time, then a one-horsepower engine will suffice.
In general, one horsepower will lift 550lbs, by one foot, in one second. Use this measurement to calculate how much horsepower you will need.
Rotary Screw Air Compressor and Airflow
As this compressor uses air, airflow is the most important characteristic you should look out for. The rate that the screw compresses the air is measured in CFM, which stands for cubic feet per minute.
Usually, if you use your compressor for DIY or home improvement projects, you won’t need to buy anything bigger than a 6 CFM rating. However, rotary screw air compressors tend to start with a rating of 16 CFM.
The higher the number normally means the better it will work with your tools, so if in doubt, go with the largest number.
Rotary Screw Air Compressor, Integrated Filters, and Air Dryers
The best rotary screw air compressors will have integrated filters and air dryers built into their systems. They often call themselves “all in one,” “full-featured,” or “Total Air System” compressors, as you don’t need to buy extra parts to secure them.
These features allow you to keep the helix screws clean, so the compressor lasts for longer.
Rotary Screw Air Compressor and Electrical Phases
Depending on the type of equipment you are using, you will need either a single-phase compressor or a triple-phase. These phases help connect to the electrical currents. If you chose the wrong phase, then your equipment may be underpowered or at risk of short-circuiting.
Summary
All 10 of these rotary screw air compressors are excellent at their job, although some are a bit too large to be considered small. Depending on your need, pick the one which best suits you!
