What Size Air Compressor For CNC Plasma – Complete Guide 2023

An air compressor is an essential piece of equipment for anyone who wants to use a CNC plasma cutter. Plasma cutters require a constant source of compressed air in order to function properly, and an air compressor is the best way to provide that. But what size air compressor for CNC plasma is required?


The answer to that question depends on a few factors, including the size of the plasma cutter, the thickness of the material you’ll be cutting, and the duty cycle of the plasma cutter. In this article, we’ll explain all of those factors and help you choose the right size air compressor for your CNC plasma cutter.

What Size Air Compressor For CNC Plasma

The size of the plasma cutter is the most important factor to consider when choosing an air compressor. Plasma cutters are rated by their amperage output, and the amperage output determines the size of the air compressor you need. For example, a plasma cutter with a 40-amp output will require a much larger air compressor than a plasma cutter with a 20-amp output.


The thickness of the material you’ll be cutting is also important to consider. The thicker the material, the more air the plasma cutter will need in order to perform the task efficiently.


For CNC plasma, you’ll need an air compressor with a CFM rating of at least 4-6 and a PSI rating around 60-90. HP should be in the 3-6 range, and the tank size should be around 6 gallons or higher.


Minimum Size Air Compressor For CNC Plasma


What Size Air Compressor Is Required For CNC Plasma?

If you’re looking for a air compressor for your CNC plasma cutter, you’ll need to take a few factors into account. The size of your compressor will largely depend on the size of your plasma cutter. A small plasma cutter may only require a 3-4 horsepower (hp) compressor, while a larger cutter may need a 5-6 hp compressor. In addition, you’ll need to consider the pressure and volume requirements of your plasma cutter. Most plasma cutters will require at least 60-90 psi and 4-6 cfm of air flow.


Once you know the requirements of your plasma cutter, you can begin to narrow down your search for the perfect air compressor. If you’re looking for a compact and best portable air compressor, a pancake air compressor may be a good choice. These compressors are small and lightweight, making them easy to move around. If you need a higher-powered option, a belt-driven air compressor may be a better choice. These compressors are more powerful, but also larger and heavier.


If you’re cutting thick material, you may need a higher air flow rate. For example, if you’re cutting 1/2″ thick steel, you’ll need at least 8 CFM of air flow. The air compressor you choose should also have a tank size that’s appropriate for your needs. A small tank will require more frequent refills, while a larger tank will be able to run for longer periods of time.


When choosing an air compressor for your CNC plasma table, it’s important to consider the quality of the air you’ll be using. Chose an air compressor that can deliver clean, dry air is essential for good cut quality. If you’re using a lower-quality air compressor, you may notice more issues with the quality of your cuts, including porosity and uneven edges.


What Is A CNC Plasma?

A CNC plasma is a computer-controlled cutting machine used to cut metal. The metal is cut by a plasma torch, which is a type of torch that uses a plasma arc to create high-temperature plasma. The plasma torch is controlled by a computer, which allows it to cut very precise shapes.


CNC plasma cutting machines are used in a variety of industries, including automotive, aerospace, and shipbuilding. They are also used to create signs and artwork.


Types of CNC Plasma:

CNC plasma machines can be classified into several different types:


1- Table Top CNC Plasma Machine

2- Gantry Type CNC Plasma Machine

3- Portable CNC Plasma Machine


1- Table Top CNC Plasma Machine:

The most common type is the table top CNC plasma machine. These machines are typically small and compact, making them ideal for use in a home workshop or garage.


2- Gantry Type CNC Plasma Machine:

Another type of CNC plasma machine is the gantry type. These machines are larger and more expensive than table top machines, but they offer a much larger working area. Gantry type machines are often used in industrial settings.


3- Portable CNC Plasma Machine:

The last type of CNC plasma machine is the portable CNC plasma machine. These machines are designed to be used in a mobile setting, such as on a construction site. Portable CNC plasma machines are typically smaller and less expensive than gantry type machines.


How Much PSI Is Required For CNC Plasma?

The amount of PSI (pounds per square inch) required for a CNC plasma cutter depends on a few factors. The first is the material being cut. Softer materials like aluminum will require less PSI than harder materials like steel.


The second factor is the thickness of the material. Thicker materials will require more PSI than thinner materials.


The third factor is the quality of the cut. If you want a clean, precise cut, you’ll need more PSI than if you’re just looking for a rough cut. And finally, the speed of the cut also plays a role. Faster cuts will require more PSI than slower cuts.


So, how much PSI do you need for your CNC plasma cutter? It really depends on the factors mentioned above. However, a general rule of thumb is to start with around 40-60 PSI for most materials and adjust from there based on the results you’re getting.


How Much CFM Is Required For CNC Plasma?

The amount of CFM required for CNC plasma cutting depends on a few factors, including:


-The thickness of the material you’re cutting

-The type of plasma cutter you’re using

-The quality of the cut you’re looking for


Generally speaking, the thicker the material you’re cutting, the more CFM will be needed.


Material:

When it comes to operating a CNC plasma cutter, one of the most important factors to consider is the volume of air that is being moved through the cutter. This is typically measured in cubic feet per minute, or CFM. The amount of CFM required for a CNC plasma cutter will vary depending on a number of factors, including the size of the cutter, the material being cut, and the thickness of the material.


In general, the larger the cutter and the thicker the material, the more CFM will be required. For example, a cutter that is designed for cutting thin sheet metal may only require 30 CFM, while a cutter that is designed for cutting thicker plate steel may require 60 CFM or more.


Size of CNC Plasma Cutter:

To determine the CFM requirements of your CNC plasma cutter, another thing you need to do is identify the size of the machine. The table below shows the approximate CFM requirements for various sizes of CNC plasma cutters.


Small (up to 2′ x 2′ cutting area): 4-6 CFM

Medium (2′ x 4′ cutting area): 8-10 CFM

Large (4′ x 8′ cutting area): 12-14 CFM


The next thing you need to consider is the material you’ll be cutting. Some materials, like aluminum, require more air than others. The table below shows the approximate CFM requirements for various materials.


What Tank Size Of Air Compressor is Required For CNC Plasma?

Your CNC plasma cutter will have specific requirements for both volume and pressure. Once you know these two numbers, you can determine the tank size of air compressor you will need by using the following formula:

(CFM x PSI) / 14.5 = HP


For example, let’s say your CNC plasma cutter requires 4 CFM of air at 90 PSI. Using the formula above, we can determine that you’ll need a 3 HP air compressor.


Keep in mind that this is just a general guideline. The specific air compressor you’ll need may vary depending on the make and model of your CNC plasma cutter.
