Jenny Air Compressors For Sale

Buyer’s Guide – What To Look For

Which gas or electric Jenny Air Compressor you select is obviously going to depend on your needs. Construction, manufacturing, and fire safety are excellent examples of environments requiring the application of an air compressor and each environment will require specific traits presented strongly in the model which they select.

You also need enough CFM to go around. For instance, in a pneumatic tool shop, each worker is likely going to need at least 5 CFM to run their tools, so ultimately you must factor in tool requirements with the number of workers in mind as well to know if your compressor is going to perform as you need it to.

In order to select the right compressor for your needs you will want to be aware of and look for the following traits:


Short for ‘Pounds per square inch’, PSI is a measurement that you will want to be aware of when choosing your compressor. So what is it, specifically? Well, PSI is a force in relation to the area.

When an area increases in size, the PSI level your Jenny Compressor is producing will naturally decrease in force as well.

Most tools are going to require a PSI range of 40 to 90 in order to be able to run your tools and depending on the tool, possibly even higher.  It is also associated with your CFM, or cubic feet per minute which we will discuss next. 


The cubic feet per minute is the measurement of the actual volume of air being pushed by your air compressor. This is actually the most important value to ascertain, as this in conjunction with your PSI is going to decide what exactly you can do with your Air Compressor.

For instance, here is an assortment of popular tools with their CFM  and PSI requirements:

As you can see, needs can be diverse amongst the tools, so as a general rule you will want to find out which of your tools has the highest requirements and shoot for the Jenny offering with the minimum CFM and PSI for this, if not higher.

Why higher? Easy. Having more than you need puts off the need for upgrading when you expand your operation. 


Horsepower is the overall work capacity residing in your Air Compressors gas or electric engine. This is going to have an impact on CFM, as higher horsepower always means more CFM, and so it is best to remember it this way:

Your horsepower is going to be the level of efficiency for producing the rated levels of CFM.

While horsepower is not the most important factor, always consider that a 5 HP Jenny is not going to be able to perform anywhere near the level of a 100 HP Jenny so be sure to note the rating on the Air Compressor which you select. 

Tank Capacity 

Having a high horsepower, PSI, and CFM isn’t going to help as much as you’d like if your tank capacity isn’t up to the job that you need it for. Having a higher tank capacity means less downtime for your Air Compressor, so you will want to pick a Jenny with the right size tank for your needs.

Jenny’s come with as low as 8 gallons and go steadily up, but we would generally recommend a 30 or 60 gallon to start with or even an 80 if you want to venture into more industrial applications.  


What will you be using your Jenny compressor to do? This is important to factor in, of course. The more powerful the compressor and the larger the tank than the more stationary it is going to be.

Portable Jenny’s are available if you need a model with wheels that you can move to get in place for the job at hand. This is very important if your compressor is going to be needed and you can’t always bring the job to you. 

Whether you are a DIY contractor or the owner of a busy Industrial shop, Jenny air compressors are a great choice. With high standards across the line, the hardest part can be selecting exactly which Jenny is best-suited to meet your needs.

All of the models we selected incorporate cast-iron, no-nonsense durable construction with the power to generate the CFM and PSI that you need to keep those power tools running.

Frequently Asked Questions 

What voltage will I need for my air compressor?

Typically your voltage will be around 110 volts, however, some of the larger industrial compressors can go as high as 460 volts. If you are buying one of the industrial models then be sure to check your outlet capacity onsite to ensure that it meets your minimum power requirements.    

How often should we change out the oil in a Jenny Air Compressor? 

Depending on your type of air compressor, a general rule is going to be every 7000 – 8000 hours is a good time to change the oil in your Air Compressor.

For best results, be sure to mark every change on your calendar and in your paperwork so that this is easy to keep track of. 

Can I run my air compressor on a generator?

You can, but this is not recommended. The reasoning behind this is because the electricity generated is often variable, due to fluctuations in the generated power.

This can cause abnormal stress on the workings of your Air Compressor as it requires a solid, consistent source of power. We would recommend that you use a gas compressor in cases where the electricity is not 100% dependable.

What happens if the water is not draining completely draining from my Jenny air compressor? 

Your compressor tanks are going to be made out of steel and as such, water accruing in a tank can lead to rust. You will want to check with your Jenny representative if this turns out to be the case in order to ascertain the best way to drain the tank for your specific model. 

How long should my Jenny Air Compressor last?

Jenny Air Compressors are extremely robust and with industrial-grade Jennys, you are looking at 40,000 to 60,000 hours of service. With regular maintenance, you can likely expect top performance for a period of 10 to 15 years.

Smaller Jenny compressors should get a 5 to 10-year top-performance lifespan depending on the overall usage time and the consistency of maintenance applied to your Jenny product. 

If my tools require a low-pressure application, how do I compensate for this with high-pressure storage in my Jenny compressor? 

This is an excellent question and happily, it comes with a simple answer. What you need to do is to install a pressure regulator to your line.

This allows you to select the pressure that you require for your tools so that you are getting exactly what you need.
