ir 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 that two tank’s hosepipe with the third hose cap in the input holes.
Fix the tool with the output hole in the cap.
Switch on the air compressor to refill the tank. (It may take longer than before as there are two tanks now)
See the gauge at the hose cap. Twist the regulator up so that it can produce a maximum CFM level.
Before using the tool, adjust the CFM level with the tool.
You are ready to operate your targeted job.
How can I find the CFM level of my air compressor?
1. At first, we have to find the volume of the tank in gallons.
2. Get the volume and divide by 7.48. Here you will get a cubic foot, as one cubic foot is equal to 7.48 gallons.
3. Flow out the tank and refill again.
4. Watch the time it is taking to refilling the tank. Look at the gauge.
5. Calculate the time it has taken to refill the tank in PSI.
6. Divide the calculated PSI by 14.7. We got P in ATM.
7. Multiply V with P and divide by 60. We got the CFM. Bottom line: As air compressor tanks to hold compressed air, it may be risky to handle. It is better to hire an expert to increase the CFM level on your air compressor.
