Air compressors are heavily used in many places like industries, manufacturing firms, automotive factories and construction sites. You cannot power many pneumatic tools such as impact wrenches, nail guns, sanders and pain sprayers without air compressors. The performance of these tools depends entirely on the effectiveness of the air compressor; the higher the airflow provided by the compressor, the better is the performance of these tools. You should know that CFM (cubic feet per minutes) is used to measure the volume of air given by the air compressor, and the higher the CFM, the more powerful the air compressor.
There are a number of ways to increase the CFM of an air compressor. In this article, we will describe some of the most effective methods.
01: Upgrade the Air Compressor Pump
The air compressor pump is the heart of the system. It compresses the air and delivers it to the tank. Upgrading the pump is one of the most effective ways to increase the CFM of an air compressor. A larger pump with a higher horsepower motor can compress more air and deliver it to the tank faster, resulting in a higher CFM. However, upgrading the pump can be expensive, and it may not be suitable for all types of air compressors.
02: Increase the Tank Size
The tank size plays a crucial role in determining the CFM of an air compressor. A larger tank can hold more air, which means that the compressor can deliver more air at a higher CFM. Increasing the tank size is a relatively easy and cost-effective way to increase the CFM of an air compressor. However, it is essential to make sure that the new tank size is compatible with the existing air compressor.
03: Use a Larger Diameter Hose
The diameter of the air hose also affects the CFM of an air compressor. Using a larger diameter hose can increase the CFM by reducing the frictional losses in the hose. Frictional losses occur when the air flows through the hose, and the smaller the diameter of the hose, the higher the frictional losses. Using a larger diameter hose can reduce these losses, resulting in a higher CFM.
04: Use Shorter and Larger Diameter Pipes
Similar to using a larger diameter hose, using shorter and larger diameter pipes can also reduce frictional losses, resulting in a higher CFM. This method is particularly useful for stationary air compressors, where the pipes can be customized. Using shorter and larger diameter pipes can also improve the overall efficiency of the air compressor.
05: Use a Two-Stage Air Compressor
A two-stage air compressor compresses the air in two stages, resulting in a higher CFM. In the first stage, the air is compressed to an intermediate pressure and then cooled before entering the second stage, where it is further compressed to the desired pressure. Two-stage air compressors are more efficient and can deliver a higher CFM compared to single-stage air compressors. However, they are more expensive and may not be suitable for all applications.
06: Use a High-Flow Air Filter
The air filter is an essential component of an air compressor. It removes impurities from the air before it enters the compressor. Using a high-flow air filter can improve the airflow, resulting in a higher CFM. High-flow air filters have a larger surface area and are less restrictive, allowing more air to flow through.
07: Adjust the Pressure Regulator
The pressure regulator controls the output pressure of the air compressor. Adjusting the pressure regulator can increase or decrease the CFM of an air compressor. Lowering the output pressure can increase the CFM, but it may not be suitable for all applications.
In conclusion, increasing the CFM of an air compressor is essential to improve the performance of pneumatic tools. There are several methods to increase the CFM, including upgrading the air compressor pump, increasing the tank size, using a larger diameter hose, using shorter and larger diameter pipes, using a two-stage air compressor, using a high-flow air filter, and adjusting the pressure regulator. Each method has its advantages and disadvantages, and the suitability of each method depends on the specific application and requirements.
It is essential to note that increasing the CFM of an air compressor may also increase the power consumption and noise level. It is essential to consider these factors when choosing a method to increase the CFM. Additionally, it is crucial to follow the manufacturer’s guidelines and safety instructions when modifying or upgrading an air compressor.
To conclude, by this time, you must have realized that if you want to enhance the performance of pneumatic tools and boost productivity, you have to increase the CFM of your air compressor. The methods which we discussed above can help you increase the CFM of your air compressor significantly. You need to select the most appropriate method, which depends on specific requirements and application. Please consider the cost, power consumption, efficiency and safety while making your decision.
