Best Twin Tank Air Compressor Buyer’s Guide

Yes! Finally, we can now discuss the individual factors to put into play when buying your air compressor. There are many models out there and settling with one is challenging. However, everyone has different preferences and above all different job tasks. Therefore, you should look for factors that are effective for your preferred project. Let’s run through them to be well acquainted with what you need.

Power source

There are two main sources of air compressor power, which are either gas or electricity. First, you must confirm if your unit is compatible with the standard household voltage. Electric-powered units are preferred since they are fumeless thus environment friendly and can be used indoors. On the other hand, gas-powered units are more powerful but emit fumes. However, they are the best option for places with power outages. Remember to properly ventilate the rooms when using a gas-powered air compressor or use it outside.

Performance rating

The performance rating of an air compressor is determined by the volume of air it can deliver at a specific pressure. For example, 4.2 CFM at 90 PSI, 5.2 CFM at 40 PSI. The CFM stands for cubic feet per minute. Therefore, you must confirm from your tool the amount of air it requires. The tool won’t operate if the air supply by the compressor is below the limit it requires.

Tank size

A twin stack air compressor is effective since it carries twice the volume of air and can run your operation for a longer period. Tools that demand more air supply will make you get a larger tank. For instance, a tool like a spray gun needs to run continuously to maintain an even paint coat. Therefore, you’ll need a larger capacity tank to maintain the flow before you stop for a refill.

Portability

Portability is another crucial factor that applies when it comes to buying an air compressor. More so, if you are a contractor, DIY enthusiast, or a professional who moves frequently to different sites.

Portability is determined by the weight of the air compressor as which makes it easy or bulky to carry. Another feature that reflects portability is the presence of wheels for easy locomotion either within or out of the working station.

Oil-free or oil-lubricated 

An air compressor can be oil-lubricated or oil-free depending on the technology used for lubrication. Oil-free units incorporated a slippery material called carbon fiber or Teflon that helps to reduce friction between the contact parts. Furthermore, they are light and require less maintenance.

On the other hand, oil-lubricated air compressors use a special oil to reduce friction. They are heavier but runs more smoothly and quietly. Moreover, oil-based units minimize tear and have a longer service life.

Final Note

Twin stack air compressors are popular since they give you sufficient air to run your air tools. However, they are a bit costly compared to hot dog air compressors, but the services are worth the price tag. All you need to do is to arm yourself with our insights on how to choose the best twin tank air compressor. 

First, check on your project needs and resonate with the factors we’ve listed above and you will have a head-start in making a prompt decision. Let me wish you all the best as you shop around!
