About the Company

In the early 1980s Harbor Freight Tools introduced the Central Pneumatic brand. They had one simple goal: Create a line of air compressors, accessories, and tools that would meet the quality of leading brands like Makita and DeWalt, but offer them at prices that would be more competitive and within reach of both home DIY enthusiasts and construction professionals.

More than 30 years later, the company has definitely met their initial goals, and in doing so, they have become a trusted name in air compressor technology.

Central Pneumatic offers a range of different devices, including pancake compressors, large portable upright compressors, and automotive compressors in the familiar long barrel shape. Along with their main units, they also provide high-quality air tools which are used by both professionals and homeowners who are looking to find a great performing tool at a competitive price.

Before we dive into Central Pneumatic and what they have to offer, let's take a look at the different types of compressors available on the market today.

Types of Air Compressors

There are three basic types of air compressors: Reciprocating, rotary screw, and rotary centrifugal. Each type has it's own set of specifications including the number of compression stages, cooling method, drive method, lubrication, and whether they are packaged or custom built.

In addition, air compressors are available in either oil or oil-less designs. Central Pneumatic tends to target smaller workshops, the DIY market, and the automotive repair market. They offer at least one model that's gas powered, and their largest tank size is 60-gallons.

How to Maintain a Central Pneumatic Air Compressor

Fixing vs. Buying a New Air Compressor

Since Central Pneumatic is an affordable and budget-friendly brand, you can take advantage of the situation and upgrade your air compressor without breaking the bank. Or, if you choose to make the repairs, the parts are typically easily assessable and reasonably priced.

Central Pneumatic is an excellent entry level air compressor, and if you decide you want to replace a broken unit, you may want to move to a more expensive brand. This is especially true if you use your compressor daily for bigger jobs. However, many owners prefer to stick with Central Pneumatic air compressors for their budget friendly prices and excellent reliability.


Troubleshooting Central Pneumatic Air Compressors

Even the best air compressors have problems, but in many cases you can identify and solve the issue yourself. Here are a few of the most commonly asked questions regarding how to troubleshoot your Central Pneumatic air compressor:

What if my air compressor stops building pressure?

If you find that your pancake, oil-less air compressor stops building pressure, it could be a valve issue, or a gasket has blow out. If you have an oil lubricated air compressor that won't build pressure and runs continually, it could be a bad power supply, intake valves, pressure valves, gasket failure, or bad piston seals.

Central Pneumatic won't start: What do I do?

While it might sound silly, you still need to check - if the air compressor is plugged in? Before moving on, make sure that it is plugged securely into the wall socket and it has not fallen out. Next, you want to check and see if any breakers have been tripped.

If so, you can reset the breaker and change the fuse. If none of this works, there may be another kind of electrical problem which could possibly be a pressure switch shorting out or a failed start capacitor.

Why is my air compressor bogging down while in use?

Always ensure that the air compressor is using power without an extension card and check the intake filter to make sure it is still clean. If you find that your motor begins to overheat, then it could be other problems related to the motor, or the power supply,
