Can An Air Compressor Be Stored Outside? A Detailed Guide

An air compressor is a versatile tool that can be used for a variety of purposes, from inflating tires to powering air tools. While most air compressors are designed for indoor use, some models can be stored outside, however before you store your air compressor outdoors, there are a few things you need to keep in mind which I will be discussing in this guide and I will be answering other question related to it so without any further ado let's take a look at it.

Before Installing an Air Compressor Outside There Are Some Things To Consider:

When it comes to installing an air compressor outside, there are a few things to consider before going ahead with the project which is given below.


When operating an air compressor, it is important to be aware of the effects that moisture can have on the air compressor. Moisture can cause rust or corrosion, which can lead to problems such as leaks as well as reduced efficiency, and in extreme cases, moisture can cause the compressor to fail.

Climate And Weather:

The climate and weather can have a big effect on air compressors that are outside. If the temperature gets too cold, the compressor can freeze and stop working. If it gets too hot, the compressor can overheat and also stop working. Also, snow or rain can affect the compressor by causing corrosion or rust and winds can also cause problems by blowing dirt or debris into the compressor which can lead to different issues.

Dust Or Debris:

An air compressor is a vital piece of machinery for many businesses and homeowners but when an air compressor is kept outside, it can be vulnerable to dust and debris. This can cause a number of problems, including decreased efficiency and shortened lifespan.

Dust and debris can clog an air compressor’s intake filter, causing the machine to work harder to draw in air and this can lead to increased wear and tear on the compressor, as well as decreased efficiency. In extreme cases, dust and debris can even cause an air compressor to overheat and shut down.

How You Can Keep Your Air Compressor Outside:

An air compressor can be a great addition to any workshop. They’re perfect for powering tools like impact wrenches and nail guns and If you don’t have the space to keep your air compressor inside, don’t worry. There are a few things you can do to keep your air compressor outside without damaging it such as:

Put It On A Solid Place:

It's important to place your air compressor on a solid surface, such as a concrete pad when using it as this will help prevent the machine from vibrating and causing damage to itself or whatever it's attached to. And also inspect the ground to see if there is moisture in it as the moisture can cause the air tank to develop rust or corrosion.

So if you want to use an air compressor outdoors, make sure the surface is level as well as free from dirt or moisture and is able to support the weight of the machine.

Place It Where There Is Clean Air:

If you are looking for a place to put your air compressor, it is important to choose a location that has clean air. This will ensure that your compressor will not become clogged with dirt and debris, which can limit its performance.

One option is to place the compressor outside, away from any sources of dirt or dust, and also the compressor intake should not be located near exhaust fans, open flame, or other sources of heat or contamination.

Install A Automatic Drain Valve:

If your air compressor is outside, then you need to install an automatic drain valve. An automatic drain valve will save you time and money by preventing rust and corrosion in your air compressor. It will also prolong the life of your air compressor by keeping the moisture out and if you forgot to drain the compressor it will automatically do that for you.

Cover It:

If you're using an air compressor outdoors, it's important to keep it covered from the weather as exposure to sun, rain, or snow can damage the machine and shorten its lifespan. So it is best to build some type of three or four-sided cover for it to save from harsh weather conditions and if you are planning on building it then you should leave some space for ventilation to prevent the compressor from overheating.

Insulate The Air Lines:

Compressors which are placed outside are subject to cold weather and freezing temperatures. This can cause problems with the airlines, resulting in loss of pressure and decreased efficiency so it is important to insulate the airline of the air compressor which is outside to prevent these issues.

There are a few different ways to insulate the airlines so whichever method you choose, be sure to cover the entire length of the airline and seal any gaps or openings. This will ensure that your compressor runs smoothly and efficiently, even in cold weather conditions.

Wiring Of The Air Compressor And Breaker:

If the air compressor is outside then you will need long wires for it to operate so for this I recommend that you hire an expert for this job and for safety you should add a breaker box for the compressor.

Keep The Air Compressor Empty When You Are Storing It:

One of the most important things you can do for your air compressor is to make sure it is empty when you store it. An air compressor that is not emptied before storage can develop rust or corrosion and this can cause serious damage to the compressor and may even render it unusable.

In addition, an air compressor that is not emptied before storage is more likely to freeze in cold weather and if your air compressor does freeze, it can burst and cause serious injury. To avoid these potential problems, simply make sure to empty your air compressor before storing it away.

Frequently Asked Questions (FAQ):

Can Air Compressors Get Wet?

Yes, air compressors can get wet however, it is not recommended as it can cause damage to the air compressor and can also develop rust or corrosion. If water does get into the compressor, it is important to drain it out immediately and dry the unit off completely before using it again.

Can You Store An Air Compressor In The Shed?

If you're planning on storing your air compressor in a shed, there are a few things you need to take into consideration. First, you need to make sure the shed is big enough to accommodate the compressor, and second, you need to ensure the shed has proper ventilation. Third, you need to protect the compressor from the elements or moisture, and as long as you consider these precautions, storing your air compressor in a shed shouldn't be an issue.

However, it's always best to consult with the manufacturer of your particular model before making any definitive decisions.

Can You Store An Air Compressor In A Garage?

The answer is yes, you can store an air compressor in the garage however, there are a few things you need to take into consideration before doing so. First, consider the temperature in your garage as the air compressor needs to be stored in a cool, dry place and if your garage gets too hot in the summer or too cold in the winter, it’s not ideal for storing an air compressor so you need to have proper insulation. Second, think about the space you have available as an air compressor can be a bulky piece of equipment so make sure you have enough room to store it safely and that it won’t be in the way of your car or other tools and equipment.

And also keep it safe from dirt, debris, and moisture when storing it in the garage as they can cause damage to the air compressor and can also lead to other issues.


An air compressor can be stored outside as long as it is covered and protected from the elements and it is important to make sure that the air compressor is regularly maintained as well as serviced to avoid any potential issues.
