Speedaire Air Compressors

Speedaire air compressors are sold by a very large industrial distribution company in the United States known as Grainger.

Over the years the Grainger name has become synonymous with entry level up to high-quality industrial level tools, monitoring equipment, ancillary equipment, and air compressors.

The Speedaire brand of air compressor is Grainger’s own house brand.

An image of one of their larger Speedaire air compressors follows.

Grainger’s range of Speedaire Air Compressors

Under the Speedaire air compressor brand, Grainger currently offers portable air compressors in the range of .33 CFM up to about 10 CFM.

Their stationary electric compressor line ranges up to about 100 CFM of air delivery at 90 PSI, with a range of tank and motor sizes.

Grainger also supplies under the Speedaire brand a full line of replacement compressor pumps and a variety of gasoline powered portable and stationary compressors.

Like many companies that sell air compressors any more, Grainger does not make their own air compressors. While not privy to the actual process, we expect that periodically Grainger reaches out to the compressor manufacturing community – and many of these firms are in the Orient (or have their compressor components manufactured there) – and gets them to bid on a job lot of XX-model of air compressor.

That means that your Speedaire Air Compressor model YYY that you purchased a few years ago, may not have the same manufacturer as the model YYY that’s available from Grainger today, even though it’s the same exact model number and overall appearance.

Speedaire Air Compressors Parts & Maintenance

Unlike many of the big box stores that sell various brands of air compressors, Grainger actually supports their brand.

You must understand however that they have been selling Speedaire brand compressors for decades, and no company, regardless of how big they are, stocks parts and service information for products sold 10 – 15 or even 20 years before.

Having said that, the first place to go for replacement parts and service information on Speedaire air compressors is Grainger themselves. We find their website, since it encompasses so many products, a bit hard to navigate, but do feel free to try.

As far as we are concerned though, if we need parts for a Speedaire air compressor, we will call them.

I have a speedaire 5z404 and the small safety valve (75psi) keeps popping open I am assuming air is leaking from the high pressure piston to the low pressure. Any idea what part would most likely need to be replaced?

Hi I found this Speedaire 5z598c at an estate sale. Never really been used. It fires up and fills to 120psi rather quickly then the motor stops and a burst of air comes out until it hits 90psi, then the air stops coming out, the motor kicks back on and fills to 120psi and does the same thing again….over and over any ideas?

I have what I think is a late 70’s or 80’s 20gal.(horizontal) speedaire compressor. I bought it at a car show got it home and plugged it in. It ran for a bit but then got hot and started to knock pretty bad. So with that said I need to rebuild the pump, funny thing about it is that there is no id info anywhere on the pump that I can see. It has a 1hp dayton electric motor. It does have 121 marked in the phase box on the tank tag all the other boxes are blank. I will… Read more »

I am in need of a small compressor that provides supervisory air to a fire alarm system that patentes date back to 1918. The existing one cannot be found so I was wondering if I can use a speedier 22vx72 . This is an air motor and wondering if I can power it with a electric motor to get app 20 ounces of air out of it. It would not run continuous but intermittent to hold system pressure of app 1.5 lbs thank you

Purchased new in 1990
I see that you don’t have any answers to my questions about pumps matching 5 HP elect motor
I talked to Granger and they wanted to sell me one that a 3 HP electric motor would run! if that would be the case why would Speedaire put a 5 HP motor on this unit that would cost more to run??

I have a Speedaire sixty gal.upright air compressor with a 5 HP electric 230 Volt motor and want to replace the pump because it is making lots of noise and takes forever to fill! My parts manual shows Model 5Z185 but I’m sure this has been replaced with a newer model part number I’m very concerned because the salespeople of various places want to sell me a compressor pump that they say is the same as the one I have but only uses a three HP motor, wouldn’t you think that since I have a 5 HP elec. motor that… Read more »
