When shopping for an air compressor, you may be wondering what tank size is the best for your specific needs. The tank size of an air compressor refers to the amount of air it can hold in its storage tank, typically measured in gallons. Although larger tanks are usually more expensive than smaller ones, they offer better performance and longer run times and help reduce the risk of overworking your motor.
What is an Air Compressor Tank?
An air compressor tank is an integral part of a compressor system. It stores compressed air until it’s needed, then releases it as needed. The size of the tank affects how much air the compressor can store and how much power it can generate. This article will discuss the different tank sizes and their pros and cons.
How Does an Air Compressor Tank Work?
An air compressor tank helps to store compressed air, often produced by an industrial air compressor. Unlike other types of storage tanks, which use pressure to contain liquids or gases, an air compressor tank is designed with a strong but flexible membrane capable of withstanding high pressure from the surrounding material such as air or gas.
The tank’s membrane separates the inner and outer walls of the vessel and works in two ways: maintaining consistent pressure within and rejecting any excess pressure applied on the outside. When excess outside pressure is applied, the internal membrane will expand outward allowing for temporary stress relief to avoid weakening or corroding the outer shell of the vessel
What Size Air Compressor Tank Should You Choose?
Choosing the right size air compressor tank is important for any DIY or professional job. A larger tank can help you store more air pressure which can improve the performance of your tool. On the other hand, a smaller tank can be more cost-effective and energy efficient. Let’s explore the different tank sizes and their pros and cons.
Factors to Consider When Choosing an Air Compressor Tank Size
The size of your air compressor tank is one of the most important considerations when selecting a compressor for your specific project or job. Not all air compressors need to be equipped with tanks, but Air Compressor Tanks (ACTs) add an additional layer of convenience and benefits, such as storing air for future use or providing consistent pressure at the end use.
The tank size will not only affect how much-compressed air can be stored, but it will also determine the long-term operation life and other machine specs. Consider the following factors when choosing an ACT for your project:
When selecting an air compressor, it’s important to consider factors such as power, pressure and flow rate. These all impact how much air the tank can hold and how quickly the air will be used.
A larger tank can be beneficial in some situations since it can provide more storage capacity and allow you to use more compressed air before needing to replenish it. However, if you have a lightweight job that doesn’t require higher pressures or large volumes of compressed air, then you won’t need a large capacity tank and smaller ones will suffice.
The material of the tank plays a significant role in how well the tank performs. When it comes to air compressor tanks, two common materials used are steel and aluminum. Steel tanks are thought to be more long-lasting and durable, while aluminum tanks are lighter providing more portability. Depending on your usage, you can decide which one is right for you.
Steel air compressor tanks typically come in 1 or 2-gallon sizes, but can range from as small as .2 gallons up to 10 gallons or larger. Generally speaking, bigger is better when choosing a tank size for your air compressor as bigger sizes have longer duty cycles. However, if you don’t need much capacity and aren’t going to be handling large jobs then a smaller steel tank may be suitable.
Tank design is a critical factor when selecting an air compressor, and .3 tanks are generally recommended for operating air tools. This size tank allows the compressor to store more air and to be more efficient when used with such tools as nailers and impact wrenches.
There are two main types of .3 tank designs: upright or pancake style. Upright designs stand tall on end like cylinders positioned vertically along the floor— maximizing storage space, but taking up some height room in confined areas due to their distinctive shape— while pancake-style apply wider dimensions horizontally usually sitting straight on the floor against a wall or other available support structure flat surface.
Compressor Duty Cycle
When selecting an air compressor, the duty cycle of the machine is an important factor to consider. The duty cycle is the amount of time that a compressor can operate continuously before needing to shut down for repair and cooling down. Generally, an air compressor with a .4 duty cycle can run for 40 minutes before it needs to shut off and cool down for 20 minutes.
Overall, the size of an air compressor tank can affect the performance of your compressing unit as well as your work productivity. Tank size has an impact on key aspects of air compressor operation such as pressure, flow rate, runtime and noise level. Larger tanks can help reduce overall noise from the unit and will be able to hold more compressed air before it needs to be refilled, making them ideal for large projects.
