The Speedaire 3z406 compressors are decades old now and are no longer supported by Speedaire / Grainger.
The Speedaire 3Z406 compressor has a horizontal tank about 30 gallons in size, two wheels at the rear, and a handle to drag it along, making this a portable compressor. It came with a 1 HP 120 VAC motor. This model was built back when a 1 HP motor on a decently pump could be relied on to last a long time and deliver a respectable amount of compressed air.
I suspect there are lots of these Speedaire compressors still in use and being of the 1970’s vintage, this compressor was probably built a lot better than similarly sized air compressors are today. It looks “real”.
Given that it’s long out of date, owners may be having a bit of an issue getting information and help with this model. Are you one of those?

People looking for the 3z406
I believe Jerry Kirkegaard is right.
Do a search for the 106.173780
You’ll find the parts diagram and parts. That should be all you need.
Have fun.
Good afternoon –
I, too, recently acquired a speedaire model Model 3Z406, and I wondered if you ever received the manual for the Craftsman compressor that another reader mentioned in an earlier post – access to a manual would be greatly appreciated.
Thank you in advance for any assistance available
I have a Speedaire 3z406 and I am looking for some sort of manual or spec sheet. Not having any luck finding anything. I found info for a 2Z499, not sure if they are the same though.
Hello,
I was looking for parts when I came across your site I was viewing the section on the Speedaire 43Z406 and at the end you were asking for information on said unit. I have a Sears model106.173780 owners manual and I believe it is the same as the Speedaire 3Z406 and if you wish I will send a copy to you.
I also have the compressor purchased in 1975 still running. It paid for itsself first time I used it painting the kitchen cabinets
Regards,
Jerry
does anybody have a users manual for my ez406 speedaire compresser. Thanks Mike R.
What was the cfms on this air compressor
Shortly after my husband died someone burglarized my garage and stole several items including all his tools and 2 speedaire air compressors. One looks like the 3z406 and I’m trying to value it for the insurance claim. Can any one tell me what it is worth? Thanks!
