The larger the compressor, the more it can supply. This is just a simple fact of physics and needs to be considered when you’re outfitting your garage or workshop for airpower. There are many things that need compressed air: paint sprayers, sandblasters and even pneumatic tools like impact wrenches and nailers all rely on compressed air. For most people, the biggest demand for compressed air is at their tool, so that should be supplied first, but there are often other needs.
Compressors for tools need to be able to provide enough CFM (cubic feet per minute) of compressed air in order to run efficiently and not burn out your gun or impact wrench after only a few minutes of use. These types of tools can require anywhere from 5-60 CFM depending on its duty cycle (how long it runs before needing a cool-down period). If you’re using an impact wrench, all day long you’ll want something like the Hitachi WH18DBDL 18V Lithium-Ion 1/2 inch high torque impact wrench with 100-foot lbs max torque and very high CFM – about 40.
If you’re using a spray gun or paint, that’s when the larger compressors come in. Even with smaller air compressors, say 5 HP or so, you can use smaller duty cycles on tools like this than run your air compressor all day long at 100% duty cycle.
The most common type of large-capacity air compressor is the rotary screw. This is where the piston, cylinder, and head assembly are attached to a rotating spindle which is driven by either an electric motor or gas engine. There are also two-stage compressors that, instead of one spindle, have two with pistons on opposite ends (think of an engine block, with two pistons at 180 degrees).
Another common type of compressor is the stationary reciprocating assembly. The piston moves in a cylinder that compresses gas or air. This allows for relatively easy piping and component replacement, but because all the components are fixated together to move as one unit, it can be difficult to find one that fits your needs. This type of compressor is typically used for industrial purposes, but there are smaller businesses that use this type as well.
The last type of high CFM air compressor is the rotary vane. Here, the pistons slide inside a rotating cylinder and compress air or gas against the vanes on the inner wall of the cylinder. These types of compressors are less common than their reciprocating counterparts, but they offer better oil control capabilities because they can be lubricated by an external oiling system.

High CFM Air Compressors: A Buyer’s Guide
CFM – The abbreviation for “cubic feet per minute”, is a standard unit of measurement that refers to how much air the compressor can pump. A higher number means it can fill larger spaces and do so faster. It’s important to note that different tools can use more or less air and that without enough CFM the compressor will shut off. Since this is a standard unit of measurement you should be able to find information for any tool on its air consumption, and know if it needs a 1-HP or 2-HP model.
Most compressors range between 50 and 150 cubic feet per minute (CFM), but there are outliers with as low as 20 CFM and as high as 500 CFM – these models are typically industrial grade and aren’t necessary for everyday household projects. Larger machines often have cast iron housings which allow them to handle higher PSI levels as well as heavy-duty motors that produce high cycling rates.
The right CFM rating will depend on the tools being used. Higher-powered compressors should be reserved for high-demand applications such as using a framing gun, impact wrench, or pneumatic ratchet. In most cases, a compressor with an 80 to 120 CFM output is sufficient for both casual home users and professionals alike.
PSI – Also referred to as “pounds per square inch”, PSI is another way of measuring air pressure inside a tank. The higher the pressure, the more powerful it is – up until a point where the machine can no longer handle it without blowing out any seals. This limit varies from model to model but in general terms you your air compressor to have a minimum of 90 PSI for it to effectively power air tools.
Compressors with higher PSI ratings will have larger motors, as well as tanks that are made from thicker materials. If you plan on using powerful tools such as nail guns or sprayers then you should opt for a machine with 130 PSI at the very least, but if possible aim for something closer to 160 PSI so your projects can be done more quickly and efficiently.
1-Stage – Utilizes one piston instead of two pistons acting against each other; this means there is no way for excess pressure to escape thus having less control over the compression process which requires frequent stops and starts to avoid damaging your tools. 1-Stage compressors are great for powering up light-duty tools such as staplers, brad nailers, spray guns, and the like.
2-Stage – Has two pistons working in unison with one another; this means you have more control over the air pressure in the tank since there is a reserve of compressed air that can be released before it reaches the tool. This allows you to avoid constantly stopping and starting while using your compressor which will prolong its overall life. 2-stage models also tend to produce less noise than their 1-stage counterparts since they’re able to produce full power with fewer stops and starts.
Compressors with multiple tanks often have valves between these tanks so you can reduce noise when you’re not using your machine.
This is a measure of the noise output from the compressor. Like any machine with moving parts, compressors emit sound as they operate, and dBA measures this level of noise which will help you determine where you should place your unit in relation to others or if it should go outside.
Compressors require air to run and as such need to store this until pressure builds up enough to be used. The more air the tank can hold, the longer it will be before you need to refill or release some pressure.
Compressor engines run on one of two types: single (one cylinder) or twin (two cylinders). A twin-cylinder engine is usually faster but choose what works best for your needs.
Oil-lubricated compressors are more expensive than non-oil ones because they require an internal pump to maintain proper levels of oil in the machinery which allows them to work at peak performance while reducing wear and tear on their parts for a longer lifespan. If you don’t use your compressor often, this might not be necessary so opt for cheaper models without oil.
Frequently Asked Questions
The choice for which air compressor to buy can be a long and complicated one, especially with all of the information available. To conclude, remember that you’ll find the best results from a compressor that has a high CFM number along with a large tank size. If it doesn’t work outside, make sure your compressor is oil-lubricated and has a quick-release valve. Lastly, know that scfm stands for how many times an air tool will use up cubic feet per minute while CFM stands for the ability of the entire machine itself.
