Speedaire: Got a Speedaire compressor problem?

Speedaire Air Compressors

One subject that surfaces constantly on this websites ASK Page is information about repairs and parts for Speedaire air compressors.

At the end of this page is a comment section where you can tell others about your Speedaire experiences and read the information that's been posted to help folks solve their Speedaire compressor issues.

Here's the current status.

I Talked With Speedaire


I had a very good chat with a very nice and knowledgeable man in Technical Support for a company known as Grainger.

Speedaire is, and has been for decades, a house brand for Grainger, and they offer a variety of products under that brand, including Speedaire Air Compressors.

No, Grainger doesn't make them. They have several manufacturers making Speedaire compressors, depending on the model. Some lower end and lower priced units are probably made in China, but for the majority of Speedaire units, they are of domestic production. Certainly the two-stage industrial units are North American made.

All this means is that you normally won't be able to contact the manufacturer of the Speedaire brand compressors directly. Rather, you'll need to contact Grainger directly for help in getting parts to repair your Speedaire compressor.





Speedaire Help


So, how do you get help with your Speedaire compressor?

You'll need some information from your air compressor, first.

You Need Your Speedaire Stock Number

Somewhere on your Speedaire air compressor there will be a nameplate, and on that nameplate will be a Grainger stock number. It will be a five digit sequence, similar to this:

8X123

Your stock number will be different, but it should (according to Grainger technical support) always be a number, a letter, and then three more numbers.

If you cannot locate the nameplate on your unit, you may be out of luck as far as parts or repairs go. Do remember that most DIY compressors are fairly low cost, and you need to weigh the cost of your time spent searching for repair parts and services against the cost of buying a new unit, which may only be in the $150-$200 range depending on the size of the unit.

When you've found the nameplate and the compressor Grainger stock number, then you'll need to contact your local Grainger outlet.

U.S.A. Speedaire Clients


If you are in the U.S., here's the Grainger branches page.

Canadian Speedaire Clients


If you are in Canada, you will need to contact your local Acklands/Grainger outlet, information here.

Speedaire Clients Outside N.A.


For Grainger outlets outside of North America, click here.

If any of these links change, they will show as invalid links. If that happens, just search for Grainger in your search engine and follow the appropriate links. And if you could let me know through the contact page, that would be good.

What now?

When you reach your local Grainger branch, advise them that you're calling about parts for Speedaire compressors, and they will either help you themselves, if the local branch has the skills, or they will often patch you through to the same T.S. people I talked to, and you will have a conference call with one of Grainger's excellent compressor Technical Support people to help you out.

No, there are no "how to it's" currently available on the Grainger sites.

If you are seeking help as to how to change a part, or fix it yourself, they cannot help you.

They can, and will, help you find parts for Speedaire compressors that are decades old.

Think it's a pressure switch?

I am appreciative of Grainger's technical support for this tip.

If you think that your pressure switch has failed on your Speedaire compressor, first, you may want to click here!
