Best Air Compressors for Home Garage

Published Categorized as Reviews No Comments on Best Air Compressors for Home Garage

So you want to convert your garage into a full-blown man-cave/workshop/mechanics playground. One of the first steps is to find the best air compressor for home garage setups. An air compressor allows you to run air tools and provides a single power source for all of your needs.

Air tools have many advantages over their electric-driven counterparts. Since they don’t need their own motors, they tend to be smaller, lighter, and less expensive. They also last longer and are more reliable since they are simple devices with little that can go wrong. Air tools are the standard in nearly all mechanics shops and factories, and there’s no reason not to have a garage air compressor.

How to Setup a Garage Air Compressor System?

Setting up your new air compressor for your home shop requires a little bit of planning. Always read the manual that comes with your compressor to see any special requirements or installation tips.

Step 1—Safety First

Keep in mind that an air compressor can make an incredible amount of air pressure. When you get your air compressor, take nothing for granted. Don’t assume that the factory did everything right and that all the fittings and attachments are appropriately secured. Wear eye protection, rubber gloves, and sturdy shoes in case of any air fittings burst. Practice good shop safety, and remember that an air compressor is a power tool.

You will also want to wear some form of ear protection if your compressor operates often or during big projects. Even “quiet” compressors make a fair amount of noise, and if you’re trapped in a loud garage with one, it can be fatiguing.

Step 2—Plan Your Installation

Where should you put your new air compressor? Every garage is different, but there are a few key things to keep in mind.

  • Give your air compressor space on all sides. It needs to have air to bring in, and it also needs air flowing around it to keep it cool.
  • Figure out the power requirements for your air compressor. You cannot use an extension cord, so you’ll need to plan an installation near an outlet or have a new outlet installed.
  • Plan to keep noise to a minimum. Keep the compressor away from doors and windows. You might even want to think about mounting it with some sound-absorbing panels to deaden the noise.
  • Where will you use your tools? Figure out how much hose you will need, and then make sure you’ve got enough. But also remember, too long a hose will lose pressure unnecessarily.

Step 3—Outfit Your Compressor with Accessories

Depending on what comes with the air compressor you choose, you’ll likely need to outfit it with a few accessories. Air filters are always a good idea to keep gunk from getting sucked into the pump. If you plan on using your compressor for painting or sanding, you’ll also want to install a dryer/separator in the line.

Most compressors do not come with the product air hose, so you’ll have to pick up the proper size hose for your application. And of course, you’ll need the air tools you want to use!

Step 4—Attach the Hoses and Tools

Attach the air hose using Teflon pipe tape on the treads to ensure a good, leak-free seal. Most tools have quick-connect fittings.

Step 5—Adjust the Regulator

You’ll need to adjust the compressor to meet the requirements of the tools you use. The compressors are adjustable to ensure maximum flexibility and versatility with the greatest number of tools.

Step 6—Empty the Compressor’s Tank After Each Use

The air tank can build up condensation, so it’s best to empty the tank every day to ensure you don’t collect a lot of water. Water can lead to corrosion and rust problems in the long wrong and contamination in the airlines.

Step 7—Mind The Maintenance Requirements

Compressors are built to last many years, but you’ll want to read the manual and follow the maintenance schedule to the letter. Oil-lubed models will require you to check the oil level regularly and replace it occasionally. Oilless compressors don’t require that but still have moving parts that will need inspection and tending to. As with all machinery, it’s better and cheaper to keep an eye on its condition and maintain it instead of repairing it.

A garage air compressor can turn your workroom into a full-blown shop. Nothing will impress your friends more or make your projects easier. The best thing about air compressors is how many uses you discover after you install one. Most folks approach the purchase with one or two tools they’d like to use in mind and then wind up using it for all sorts of things.

FAQs (Frequently Asked Questions)

What size air compressor do I need for my home garage?

An air compressor with a tank size of between 2 and 20 gallons should be a perfect fit for your home garage. Though, it is important to size your compressor based on the type of tools you intend to operate and their CFM requirements.

What is the best PSI for an air compressor?

Most air tools require PSI within the range of 70-90. The majority of light to medium-duty air compressors are capable of operating at these pressures but it is always a good idea to purchase a compressor that can operate at higher pressures to be sure. You must supply air tools with the correct pressurized air flow for them to operate efficiently.
