How much air pressure do I need for my air tools?
Air Pressure by Application. Air tools made for general use with portable air compressors typically require 0 to 5 cubic feet per minute (cfm) at 70 to 90 pounds per square inch (psi), whereas with larger tools connected to stationary systems, the requirements usually exceed 10 cfm at 100 to 120 psi.
How much psi do I need for my compressor?
A compressor operating at 90 PSI is able to deliver 90 pounds of pressure per square inch, which is important for operating air tools. A PSI too low for a given air tool and the tool won’t operate properly. A PSI too high for the tool could damage it. How Much PSI Do You Need?
What is the difference between PSI and CFM on air tools?
Most manufacturers will measure their cubic feet per minute flows in a standardized environment, so when you see a CFM rating on an air tool or compressor, assume it is SCFM. PSI refers to Pounds per Square Inch.
How do I know if my air compressor can power my tool?
To use this chart, you will need to know the PSI (Pounds per Square Inch) and CFM that a particular air tool operates and then look to see if your air compressor can power it. The majority of air tools operate in the 90 to 100 psi range and most air compressors from the smallest to the largest can easily produce this much pressure.

Why is too much pressure on air tools bad?
At the end of the day, too much pressure for your air tools can be a costly mistake. From equipment failure and repair costs to health and safety risks for your team, there are a lot of reasons you should simply use the right pressure.
How to check air pressure on air compressor?
Check the pressure at the tool: Attach a pressure gauge between the end of your hose and your air tool to confirm whether the air pressure is at the maximum recommended pressure. Each air compressor design is different, and some systems can lose pressure before the air reaches the tool. If the air is losing pressure before it meets the tool, you can try turning up the pressure a bit, but only until it reaches the manufacturer’s psi recommendation.
What to do if your tool isn't working?
Upgrade your tool: If you’ve gone through the list above and your tool isn’t getting the job done, it’s likely time for an upgrade. Tools that have enough air and are powerful enough for a job will work properly and efficiently at their recommended psi setting. If your tool isn’t performing under the proper conditions, you need a better tool.
Why do pneumatic tools wear out?
Using too much pressure can cause your air tools to wear out or break a lot sooner than they should. Here are the most common pneumatic tool repairs caused by excessive air pressure:
How much pressure should I use for a vane motor?
Vane motor breakdowns: As little as 20 psi of excessive pressure in a vane motor system can half the life of an air tool. Most tools are rated at 90 or 100 psi, so using 120 psi regularly ensures you will be replacing expensive air tools in half the time you should have to.
Why do tools wear down?
Instead, tools wear down over time until they reach a point of failure. The more a tool is worn down, the less efficient seals and other components become, even if it’s still working. This results in leaked air, which essentially means the tool needs even more air to run than it normally would. By using the right pressure for your tools, you reduce ...
What to do if air is losing pressure?
If the air is losing pressure before it meets the tool, you can try turning up the pressure a bit , but only until it reaches the manufacturer’s psi recommendation. Check the hose size: A hose that’s too small can cause pressure drops that are easily remedied by an upgrade.
Air Compressor Measurements at a Glance
There are several air compressor measurements and terms that you’ll need to be familiar with to best use a compressor. These include:
Air Compressor PSI
PSI stands for Pounds per Square Inch. This is a measure of how much force a compressor is able to generate per square inch of space. A compressor operating at 90 PSI is able to deliver 90 pounds of pressure per square inch, which is important for operating air tools.
CFM & SCFM
CFM stands for cubic feet per minute. While PSI is a measure of pressure, CFM is a measure of flow. Another way to think of this is in terms of the compressor’s output ability. How many cubic feet per minute can the compressor provide, and at what pressure (PSI).
Air Compressor HP
Chances are you’re familiar with the term horsepower. This is what HP stands for, and it’s a measure of how much power the compressor’s motor can provide. One horsepower is generally equivalent to 550 foot-pounds per second.
Tank Size (In Gallons)
You’ll also see that one of the major factors on air compressors is the size of the tank. Most compressors for home use have tanks ranging in size from 1 gallon to 10 gallons. For most people, a tank size somewhere in the middle works well — usually in the 6 to 8 gallon range.
Decibel Rating
You’ll also see compressors with a decibel rating. Decibels are used to measure noise levels. And if you’ve ever worked around a compressor before, you probably know how loud they can be.
Duty Cycle
A duty cycle is a term meant to describe how long it takes a compressor to run compared to the total time it takes to complete an entire cycle of running and resting. For example, a 25% duty cycle means that that compressor should run for a quarter of its total cycle time.
How much air pressure is needed for a compressor?
So how do you know how much air pressure is needed for a given application? Air tools made for general use with portable air compressors typically require 0 to 5 cubic feet per minute (cfm) at 70 to 90 pounds per square inch (psi), whereas with larger tools connected to stationary systems, the requirements usually exceed 10 cfm at 100 to 120 psi.
How much pressure do you need for an air nibbler?
When properly guided along sheet metal with just a minimum of arm pressure, an air nibbler requires 4 cfm at 90 psi.
How many cfm does an angle grinder need?
For general applications, a standard 7″ handheld angle grinder requires 5 to 8 cfm at 90 psi.
How much pressure does a pneumatic orbital sander need?
With only modest amounts of hand pressure, a pneumatic orbital sander requires 6 to 9 cfm at 90 psi.
How much pressure do brad nails need?
As a relatively lightweight pneumatic tool, a brad nailer generally requires only 0.3 cfm at 90 psi.
What was the task before power tools?
Before the invention of power tools, few tasks were as exhausting to the palm, wrist and elbow as sanding . While most of the heavy lifting and pressure was concentrated in the sawing, cutting and nailing stages, more actual hand motion was needed just to get each raw-cut surface refined to a nice, smooth finish.
What is Quincy Air compressor?

How much PSI should I use for a plasma cutter?
You may be able to get by with as little as 60 PSI with the smaller units. If that is the case , then a 30-gallon compressor should get you going. Frankly, though, I find most Plasma cutters to be airflow hungry, and my favorite was when I got to use one that was hooked up to a 60 Gallon air compressor like one of these .
Where does air come from in a tool?
Essentially all of the air to power your tools comes from what is stored in the tank. If you are using a tool that has a large air capacity, then a smaller tank size will not give you enough reserve air at the right CFM and PSI to keep the tool functioning as it should.
How many CFM can a pancake compressor produce?
If you are just doing construction projects around the house, a portable pancake compressor that can produce 4 CFM can do everything you need.
What size compressor should I use for carbon arc welding?

How much plasma do I need for a cutter?
Most plasma cutters that you use around the shop will likely only need about 6 CFM @ 90 PSI. There are some bigger units that require 11 CFM. To be honest, using plasma can be finicky enough, and not having adequate air flow makes it that much harder. (I say finicky, but I did run my first plasma cutter at twelve years old, so it can’t be that finicky).
How many CFM does a 6 gallon tank produce?
This is where you need to read the specifications. You can purchase a 6 gallon tank that only produces 2 CF M or one with a bigger compressor that creates 4 CFM.
Why are CFM and PSI important?
Both CFM/SCFM and PSI are important to having your air tools work at peak capability, as they are rated to work the best under given ranges for each measurement.
How big is an air receiver tank?
These air receiver tanks can vary in size from 5 gallons to over 100 gallons.
What is CFM in pneumatics?
