There are certain factors you need to look into to find the right match for your needs. Below, we have highlighted some of these criteria to aid your decision-making process.
Any air compressor generator combination you set your eyes on will run on one of the three fuel types.
It could be gasoline, liquid propane, or diesel. Each of them has different electrical output and efficiency; also, you should take fuel costs into account when choosing the type.
If you’re looking to power small electrical tools in your workshop, a heavy duty diesel generator will not be necessary.
Instead, you can opt for a gasoline one, giving you a decent output, enough to run handheld tools. It is also the most popular fuel type, making it readily available.
Diesel is more widely used when running tools with high power requirements, and it is also a very affordable fuel type. Not only is it more affordable than gasoline, but it also effortlessly runs for prolonged periods of time.
Both the gasoline and diesel powered engines are hard to clean because of their thickness. If that becomes a major issue, you can always pick propane powered engines. These are cleaner, but they come at the expense of reduced total output.
Power Output and Air pressure
Once you’re settled on which power source to use, you have to determine the max power output needed from the generator.
Depending on the number of electric tools you’re looking to use and their power consumption levels, you must make a calculated assumption.
To be able to estimate your required power output, check the AC power consumption of each tool. Adding them all will give you a clear idea of how much power you should need in total.
If you’re tight on a budget, try pairing tools that are frequently used together and try to find an average power requirement.
In addition, you will need to check the CFM of the air compressor generator in order to power specific tools that require air pressure. Knowing the CFM will give you an idea of the range of air tools compatible with your generator combo.
Design and Weight
Inspecting the design and weight of an air compressor generator is essential. You need to be able to house the entire generator combo near your workshop or wherever you need it.
The build quality of the air compressor generator needs to be heavy duty in order to sustain years of use without compromising on performance.
These machines can be pretty large and heavy in size, so you need to choose according to your space requirements. Some people prefer portable options, and while that can be rare, there are combos with wheel kits and handles.
Frequently Asked Questions
AC or alternating current refers to an electrical current that can switch its flow of electrons from one direction to the other. DC, or direct current, on the other hand, can only move in one direction.
CFM or cubic feet per minute represents the air pressure released from the compressor. It measures the force at which the air is flowing from one end to another.
Mostly all air compressor generators require periodic maintenance. However, liquid propane generators are easier to clean than other fuel types, but it comes at a higher price tag.
When it comes to industrial job sites, generators need to provide multiple outlets at 120 and 240 volts. With that being said, a total of 5000 watts of power output should be enough for industrial use.
Choosing the best air compressor generator combo is a challenging task. Considering numerous factors such as durability and reliable performance, selecting the right one can be pretty daunting.
It would be best if you always focused on the purpose of the generator, whether it is to be used in a small workshop or an industrial site. This will clarify a lot about the power requirements.
In any case, all the above mentioned generators are guaranteed to give you utmost satisfaction in running all your electrical equipment. Pay extra attention to the total watt output and CFM to narrow down your choices.
