When you go out to the market to buy an air compressor, the first thing you ask is what is the CFM of the air compressor?
Then you ask what the PSI is of that compressor.
So, CFM and PSI are the two most important terms of an air compressor, and both are linked with each other.
The more the CFM is the better.
Now the question is how to increase the CFM on an air compressor?
What is CFM on an air compressor?
CFM stands for cubic feet per minute. It refers to the amount of air that comes out through the air compressor every minute.
It is an integral part of an air compressor’s efficiency. The performance of an air compressor depends a lot on the CMF that is provided by the air compressor.
Every air compressor has a certain CFM level to operate. Similarly, some tools need less CMF to operate; some need more.
CFM measures the amount of air that comes out in every minute. It shows the amount of air as cubic feet.
PSI measures the air presser in the tank and a tool as well.
Every air compressor has a certain CFM level. Certain CFM level considers the efficiency of a compressor. Different tools require different CFM level.
The operator must have the idea of the tools that he is going to operate. Low or high CFM levels may cause difficulties in action for certain tools. The requirement of the tool and the CFM level must be equal.
To ensure a good working result you must match the tool and CFM level. Normally, impact wrench and spray-painting tools require a much CFM level.
Why increase CFM level on air compressor
You will find a bundle of reasons to increase the CFM level on your air compressor. Different tools require different CFM levels to operate smoothly.
When you are using the air compressor tools to suck the dirt and dust on your floor, you may need a low CFM level. When you are washing your cars, floors, walls and so on, you may need a medium CFM level.
On the other hand, to operate impact wrench it requires much CFM level the tools related to impact wrench are heavier than other tools. These types of tools use air to rotate small metal parts that’s why they require much flowing speed.
More ever, painting tools also require much CFM level. These types of tools suck hard mixers and throw fast to a higher and lower position into the targeted object.
If you fail to match the CFM level and the operating tool accursedly, you may not get a good result from the tools and the air compressor as well.
How to increase CFM on an air compressor
There are two suitable methods to increase CFM on the air compressor. Method 2 can be more efficient than method 1.
Every air compressor has a limited CFM level. You have to use other tools regarding the maximum CFM level. There is an option to control the CFM level in the tank regulator. Using the regulator, we can make a little change in the CFM level.
The idea is to lower down the presser in the tank and increase the CFM level when the air flows out.
Power = CFM X PSI
That means if we can somehow lower down the PSI, mathematically CFM will increase, power being constant.
To do that switch on the air compressor.
It will start refilling the tank with compressed air.
Turn down the regulator attached to the tank. Just twist the regulator cap down and keep it till the tank is full.
Now fix the tool with a hosepipe and switch on the airflow. Be sure that air is flowing through at full speed.
This is a simple way to increase the CFM level. It may not work for certain tools.
Method 2 can be a little bit costly. Although the method is costly, it is efficient for all kinds of tools that need much CFM level.
We know, every air compressor can produce a limited rate of CFM. The main idea of this method is to join the two air compressors together.
Buy an air compressor with a minimum of 3 to 5 CFM level. (If you have an air compressor of 5 CFM level already)
Buy three hose cap. (Two normal hose cap and one hose cap with three mouths)
Make sure that the large hose cap has two input holes and one output hole.
Join the two tanks together. Engage the hosepipe together also. Make sure that you have engaged th
