Makita MAC2400 Big Bore 2.5 HP Air Compressor

The engineering concept behind the Makita MAC2400 consists of a combined piston and bore cylinder technology. It also has a low AMP draw for reduced tripping of circuit breakers. The compressor boasts of a 4.2-gallon tank with a 130 PSI operating pressure. Concerning pressure delivery, the product delivers capacities of 40 PSI and 90 PSI.

Also, the pump features oil lubrication that helps cool the unit and reduce the product’s wear and tear. To help withstand the rough nature of work environments, the MAC2400 has a roll cage construction. Besides, it has an automotive-style air filter. Such filters help increase air intake while also boosting efficiency.

The cast-iron cylinder not only reduces wear and tear but also provides for ease of maintenance. You can remove it during servicing. The MAC2400 also features an oil sight glass to help you monitor the oil levels.

The pump runs off a 2.5 Horsepower motor that generates 1,730 rotations per minute and low noise at 79 Db (Decibels) — the lower the RPMs, the less the sound a piece of equipment produces. By having a big bore cylinder, the unit can take in and compress more air at a single stroke.

MAC2400 is ideal for nail guns and stapling tasks like decking and sheathing. Whether you are a remodeler or carpenter, the product can handle both large and small-scale projects.

However, compared to other compressors featured in our Harbor Freight air compressor review, the BTFP02012 is not a quiet machine. It produces noise levels at 78.5 decibels. Nonetheless, 78.5 decibels are not too much. The human threshold is 110 decibels. At this level, you begin to feel pain in the ears.

With a 6-gallon tank, you can inflate tires without having to wait for pressure to build-up. Besides, the same capacity can power nailing tools for floors and other woodwork tasks. However, this product cannot handle powerful tools like the leaf and debris blowers.

At the same time, you must allow for the compressor to cool down. After an hour of continuous operation, allow between 10 to 15 minutes before resuming. Storage is not a headache as the unit’s footprint is only 23 by 34 inches. You cannot fail to find a place to keep the equipment.

Concerning power output, you only need 120 volts which you can find in household and commercial power sources. When it is running fully, the compressor draws about 1200 watts and requires around 15 amps. With a portable power source such as your car’s inverter, you can still power this device.

You can use the DWFP55126 with tools such as:

Factors to Consider When Buying an Air Compressor:


Unless exaggerated, the Horsepower rating is always the best way of determining your compressor size. The best way to differentiate between a real and overrated HP-rating is by looking at the electric power needed. For instance, a 5HP motor draws 24 amps when connected to a 220V circuit.

All the same, a compressor’s Horsepower does not necessarily translate to performance. From this Harbor Freight air compressor review, we can safely tell you that the Horsepower rating is like saying how much power or the lack of it is in an engine. A high HP rating means that your compressor will fill the air tank efficiently and reduce recovery time.

What you intend it to do

You cannot wake up one day, walk into an industrial equipment store, and walk out with an air compressor at random. You must think through a few things. If your type of work entails moving to different areas, then you need compressors with wheels.

Also, you must be prepared to make some sacrifices. For instance, portable compressors have less power than stationary ones. Besides, small units require that you keep them running for long. In the process, they consume electricity plus their parts wear out quickly.

The tank sizes

Before you consider the tank size you must bear in mind that compressor tanks do not produce air, they store it. As far as the dynamics go, you should opt for equipment with a high-capacity motor and pump. With such a consideration, you will always have the quantity of air needed irrespective of the tank size.

Some situations, for instance, occasional use, warrant seeking a small compressor but shooting for a large tank. Take, for example, where you have a 1-inch impact wrench that you do not use often. A small compressor with a large tank will serve you perfectly. However, for steady work, you need compressed air at every turn.

Maintenance or maintenance-free

Concerning maintenance, oil-less compressors require very little. However, their counterparts, for the ones that use lubricating oil, you must keep monitoring them frequently. Nonetheless, both types of compressors have some basic requirements that you must keep up with for them to keep running.

The air intake filter is an essential component of the two types of equipment. The concept used here is a simple one. The filter protects the unit from taking in dust and other contaminants. So, as the filter traps more of these, it gets clogged, causing the compressor to lose its capacity. You need to change filters and carry out other checks regularly.

Life expectancy

All the brands in our Harbor Freight air compressor review do last long. Our advice is never to buy a compressor unless you are clear on its life expectancy. Ask your dealer or find reviews that provide such information.

If you still cannot find it, visit the manufacturer’s website. Alternatively, you can contact the manufacturer directly. Oil-lubricated compressors last longer than the oil-less ones. The former category stays a lot cooler than the latter, meaning less wear and tear.


What size air compressor do I need to run air tools?

Air tools such as the sandblaster require a constant air supply. You, therefore, need compressors with a large air tank. First, you must understand the meaning of these terms:

  • CFM (Cubic Feet per Minute): means the rate of air delivery to a tool
  • PSI (Pounds per Square Inch): this is a measure of the air pressure or the force of an airflow

Most, if not all, air tools in your possession indicate their PSI and CFM requirements.

We strongly advise against assessing your air compressor requirements by the size of the unit. Instead, examine a unit’s air delivery capabilities measured in CFM. As a rule of thumb, air compressors manufactured for air tools have a delivery range of between 30 to 140 Cubic Feet per Minute.

Is Central Pneumatic a good air compressor?

Central Pneumatic is a subsidiary of Harbor Freight, a popular store chain in the US. Harbor Freight began its operations in 1977. Since then and up to the present, the company has offered quality power tools. In 1982, the company launched Central Pneumatic as its subsidiary. The latter specializes in air-powered machinery.

Each Central Pneumatic branded air compressors must first undergo a series of endurance tests. Another thing is that these are ideal for beginners, people who are perhaps looking for their first product. Besides, the brand is cheaper compared to other models. Therefore, to answer your question, yes, Central Pneumatic is a good air compressor.

Central Pneumatic will cater to your needs when you need a compressor for light work. Also, if you are on a tight budget, you can procure the brand as a game-starter.

For online purchases, you can safely use Amazon or other sites verified by Harbor Freight. Even as you do so, we recommend that you read the reviews posted by past users of a similar product. On the other hand, if you live in a region serviced by a Harbor Freight outlet, ensure that you enquire about the replacement policy. You can also count on warranties.

Nonetheless, regardless of the brand, you need to do your homework correctly. Determine your needs by assessing the work the compressor will do. After that, research the different equipment available. You will be amazed at the choices available. Compare the features and see how best or far off they are from your expectations.
