Why is my air compressor not building pressure?

by Ivan Sanchez | Last Updated March 11, 2022

Why my air compressor not building pressureThere is a range of needs for air compressors, and we need them in workplaces, homes, etc. Every job that we perform with an air compressor needs a specific pressure. If the air compressor cannot develop that value of pressure, then it might be lacking in some areas. As a result, it won’t be able to perform that job.

The better solution is to look into the machine and see if it is alright. If there is some problem with the machine, you will set it right to get the right pressure value. The problem should be solved in time, instead of leaving it to stay like that. It will improve machine efficiency and lower energy expenditure.

Here is a brief overview of checking if an air compressor is not producing sufficient pressure and how to tackle this issue.

Pressure Problems in Air Compressor

An air compressor comprises different parts that work together to help the machine develop the required pressure. These parts include the suction area, pressure developing tank, supply lines, etc. If all these are working fine, the machine would be working efficiently. If this is not the case, the results would be delays in jobs, extra energy expenditure, and wastage of time.

There can be various problems related to pressure in an air compressor. These can include decreased pressure, the increased value of pressure, and many others. Here we discuss the causes and remedies of decreased pressure. The main reasons for this problem are poor maintenance and overheating, which cause wear and tear in different parts.

As a result, the machine cannot get the user’s ideal results. The machine might not reach the cut-out pressure and lag in reaching the required value. You can check the reed valve to see if it is alright.

Some checks for the air compressor include pump-up test, filter check, screen leaks, system values, etc. You will find out which area is creating the problem.

How to fix this issue?

It is easy to fix the problem of low pressure if the user finds out the reason behind it. If you face a problem due to defective valves, then the solution is changing them. If they are not working, they won’t create torque and, resultantly, the required pressure. Though it might be technical to check if valves are performing well, you can do it by understanding how they work.

You can check the pressure switch if the problem persists. If the pressure switch has problems, you need to immediately set them right. There are chances that they will cause great harm if they go unchecked. Currently, the pressure might be low, but its problem can also rise to a dangerous level. You can also consult an expert to check this issue further.

Pump piston rings can be another reason for low pressure. They such air from the environment and push it into the compressor. It is better to change them if they are worn out. Check their seal plate, showing signs of a leak and reducing the required pressure value. Along with the reduction in pressure, it can also create problems for other parts inside the compressor. So, you need to change it immediately.

You can also check the tank for leaks, and if there is a problem, you should hire a technician. They will survey the machine in detail and let you know what changes are needed. If they tell you to change the machine, you should go for it.

Final Thoughts

An air compressor might not be showing proper results in developing pressure. The reasons for its fault can be many, and you can check individual faults to conclude. If there is any fault in a specific part, you should change it to get the required pressure. If there is some major issue, a technician can help you.
