If you’re a frequent jackhammer user, then chances are that you’ve asked yourself the question: what size air compressor is required to run jackhammer?
When running jackhammer with an air compressor, there are many factors to consider such as power levels, PSI ratings and CFM outputs. With all these confusing technical details, in mind it can be hard to figure out exactly which air compressor will work best with your current jackhammer.
In this guide, we will explain how to choose an air compressor that is right for your jackhammer needs, walking you through important factors such as horsepower rating and pressure capacity.
What Size Air Compressor For Jackhammer
For a jackhammer, you’ll need a compressor with a CFM rating of at least 4.0 to 6.0 and a PSI rating of between 90-120. HP should be in the 20-25 range, and the gallon size should be around 16 gallons or higher.
What Is A Jackhammer?
A jackhammer is an incredibly powerful tool used for breaking hard surfaces, such as concrete and asphalt. It works by using pressurized air to deliver short bursts of energy to a chisel-like bit, which then chips away at the surface until it is broken up into small pieces. Jackhammers are most commonly used in construction and demolition work, but can also be used in a variety of other applications.
Types Of Jackhammer?
There are two main types of jackhammers:
– Electric Jackhammers
– Pneumatic Jackhammers
Electric Jackhammers:
Electric jackhammers typically use a motor to create the pressure needed to break through hard surfaces, while pneumatic jackhammers rely on an air compressor for power. Both types can be used for both demolition work and precision breaking jobs, but each has its own set of advantages and disadvantages.
Electric jackhammers have the benefit of being lightweight, making them easy to transport, but they also tend to be more expensive than pneumatic models. Additionally, electric jackhammers require a power source in order to operate, so they are not ideal for remote locations where access to an electrical outlet is not available.
Pneumatic Jackhammers:
Pneumatic jackhammers, on the other hand, are powered by an air compressor and therefore don’t require access to a power source. This makes them ideal for jobs in remote areas or on construction sites that lack adequate electricity. Pneumatic jackhammers are also generally less expensive than electric models, but they are heavier and bulkier, so they may not be suitable for certain jobs.
7 Important Factors to Consider When Selecting an Air Compressor for Jackhammer:
When selecting an air compressor for your jackhammer, there are several important factors to consider. The most important of these include PSI, horsepower rating, tank size, flow meter and duty cycle.
PSI:
Pounds per square inch (PSI) is a measure of the pressure output that an air compressor can generate. The higher the PSI, the more powerful the pressurized air will be and the more likely it is to be able to break through tough surfaces.
HP:
Horsepower (HP) is another important factor when choosing an air compressor for your jackhammer. The horsepower rating of an air compressor determines how much power it can produce, so bigger, heavier jackhammers may require a higher horsepower rating.
Tank Size:
The size of the tank will also affect your selection of an air compressor, as larger tanks can hold more compressed air and therefore can provide more power for longer periods of time. A smaller tank may be suitable for lighter jobs, but if you plan on doing more strenuous work, a larger tank may be necessary.
Flow Meter:
The flow meter allows you to measure the amount of air that is flowing through your compressor and helps you ensure that it is providing enough power for your jackhammer needs. A good flow meter can also help you determine when too much pressure is being applied and therefore prevent any potential damage.
Duty Cycle:
Duty cycle refers to how often an air compressor can be used before it needs to be rested or cooled off. Most compressors have a duty cycle of around 70%, meaning they can run continuously for up to seven minutes before needing a break. Knowing the duty cycle of your air compressor will help you decide if it’s suitable for the kind of job you plan on doing.
Portability:
Lastly, you should consider the portability of an air compressor when selecting one for your jackhammering needs. If you plan on using your jackhammer in multiple locations or if it will need to be transported often, make sure to choose a model that is lightweight and easy to move around.
Now let’s discuss these factors one by one in detail.
Pressure Requirement for Jackhammer:
The amount of PSI required to run a jackhammer with an air compressor will depend on the type and size of the job being done. Light duty jobs that only require breaking up small chunks of concrete, for instance, may require as little as 4-5 PSI.
On the other hand, larger projects such as breaking up thick slabs or demolishing walls may require upwards of 12-13 PSI. It is important to select an air compressor with sufficient PSI in order to ensure that it can handle your jackhammering needs.
Horsepower Requirement for Jackhammer:
The amount of horsepower required to run a jackhammer with an air compressor will depend on the size and weight of the job being done. Larger, heavier jobs that require breaking up thick slabs or demolishing walls will likely need an air compressor with at least a 3 HP rating in order to provide adequate power. Smaller projects such as light-duty chipping may be able to get by with less horsepower.
Tank Size Requirement for Jackhammer:
The tank size in gallons required to run a jackhammer with an air compressor will depend on the length and intensity of the job being done. If you are working on larger projects that require lots of sustained power, then you may need an air compressor with a larger tank size (10+ gallon) in order to provide enough compressed air for your needs. Smaller jobs such as light-duty chipping or drill work can likely get by with smaller tanks (3-5 gallon).
CFM Requirement for Jackhammer:
CFM, or cubic feet per minute, is a measure of how much air a compressor can move in a given period of time. A higher CFM rating means that the air compressor can pump more air into the tank and will be able to handle heavier jobs with ease. Generally speaking, larger jobs that require breaking up thick slabs or demolishing walls will require an air compressor with at least 10-11 CFM.
Flow Meter Requirement for Jackhammer:
A flow meter is a device that measures the flow of air in your compressor and helps to ensure that you are getting enough power for your job. It can also be used to detect and prevent any potential damage caused by too much pressure being applied to the system. A good flow meter will help you get the most out of your air compressor and ensure that it is running efficiently and safely.
Duty Cycle Requirement for Jackhammer:
In addition to PSI, horsepower, tank size in gallons, and CFM rating of the air compressor, you should also familiarize yourself with the duty cycle. Duty cycle is a measure of how often an air compressor can be used before it needs to be rested or cooled off. Most compressors have a duty cycle of around 70%, meaning that it can be used for up to 70% of the time before needing a break.
Do You Need An Air Compressor For A Jackhammer?
Yes, you need an air compressor for a jackhammer in order to provide sufficient power for the job. Without an air compressor, your jackhammer will be unable to work properly and may cause damage to itself or other items nearby. Make sure to select an air compressor that meets your needs and is able to handle the job at hand.
