Any of you folks ever heard of a company called Grainger?Are you looking for some industrial pneumatic products? Are you looking for Speedaire air compressors?
Grainger distributes almost everything related to industrial applications in their nation-wide stores and in their massive on-line presence.
The air compressor brand Speedaire is Grainger’s own, though they also sell many other compressor brands as well, though only the Speedaire air compressor is the brand they have manufactured for their own distribution and sold to other distribution companies to offer.
The smallest Speedaire compressor we have found is a .9 HP, 120 volt tire compressor putting out 115 PSI at a massive flow of 1.7 CFM. The largest electric air compressor in the Speedaire air compressor family that we could find is the 10 HP, two stage (2 cylinder pumps) unit delivering about 34 CFM at maximum pressure and shown in the image below.
Unfortunately, no where on their specifications for this model does it show what the maximum pressure output is. We expect it to be in the 150 PSI range, but cannot say for certain.
That’s a nice range of electric air compressors, suggesting that Grainger has a Speedaire for the home and garage, mid-sized workshops, and even some large manufacturing plants using a goodly amount of compressed air.
What about Speedaire support?
Grainger has been in the Speedaire air compressor business for more than 30 years. Since they sell compressors under their brand, but manufactured by diverse companies over the years, getting part supplies for older Speedaire compressors might be tough.
The first thing you want to do is copy the model number from your Speedaire compressor and call Grainger’s spare parts support line which is currently at 1-800-472-4643. They have a pretty good support group and will be able to tell you quite quickly if you can get parts for your Speedaire air compressor from them. Oh, and you may have to listen to an ad when you first call. That sucks!
For older Speedaire compressors you may find, since Campbell Hausfeld made so many compressors for so many companies over the years, that your older Speedaire has spares available from Campbell Hausfeld. Call them at their current parts information line 1-800-543-6400 and ask, and you will need your compressor model number too.
Another source for older Speedaire air compressor parts is on-line forums etc. You’ll still need your compressor model number. Type “parts sources for Speedaire compressor xxxxxxx (x’s are your model number)” into your search browser and you be able to connect with older Speedaire parts from the search returns.
Grainger has been around a long time. They wouldn’t be in business today if they didn’t offer reasonable products at reasonable prices. Over the years, however, we feel that the quality of equipment has diminished since so much of the outsourcing is done in foreign lands, locations that cannot delivery the quality that was inherent with goods made in North America.
If you are considering a Grainger Speedaire air compressor purchase, do your homework. Ask the questions you should ask when you buy any big ticket item, questions such as:
- longest warranty available on the Speedaire compressor
- who fixes it under and out of warranty
- supply of spare parts
- turn around time of repairs under warranty
I have a 4B232B. With pump number 4B246A. It was set up to run a low pressure boiler system. Can I convert it to a standard style air compressor for garage use? The piping doesn’t look like my other speed aire, this unit only has a single line coming from the head to the tank. My other compressor has a second smaller hose going to the shut off. Any help would be appreciated.
I have a speedaire 3z322. I need a tank check valve. Any idea where or who to talk too?
I recently picked up a Speedaire 2z495 with a 1.5 hp motor. It came with some parts that Im pretty sure were either removed put in the wrong place. I have two questions:
1. The pressure switch lacks a fitting to connect to the check valve or pump. There is one pipe that goes from the pump (2z499) to the tank via a check valve and that’s it. Every other compressor Ive worked on has had another pipe to decompress the pump’s piston chamber. Is this normal for this compressor? If not. how would a 2nd pipe connect without going thru the pressure switch?
2. Can you tell me what the pictured fitting is and what is its purpose? (It is spring loaded underneath)
Thanks for your help and for the site in general.
I’m in need of a connecting rod for a Speedaire pump # 2Z498B. All indications this part no longer available by manufacturer or Grainger. Any idea if there is any substitute parts?
I have a model 39GC06 comp, gen, weld combo engine drive. My question is when it’s running in high idle for welding the air pressure release will pop and not reset. I’ve replace the valve but it still does this. Is there a fix or some adjustment that can be made to correct the issue or is it designed to do this? Thanks.
i have a dayton dual speed aire compressor and one motor turns on and the other dont . What can be the problem? Who can fix this for me? please help im in new haven connecticut
I have a Speedaire I’m looking for parts for with no luck so far. Model 1-937. Sn R30015335.
Speedaire 5Z403A 2 is the model I was trying to find a rebuild kit for the compressor pump, with no luck any help would be greatly appreciated.
I bought a speedaire 3Z395 1 1/2 hp . It doesn’t have a check valve or unloader . The pressure switch doesn’t have any unloader mechanism either . It pumps up to ~100 psi and shuts off but won’t restart because of the pressure on the head . Were these actually made like this ?
I have a Speedaire compressor model 5f237a serial number 668733. Need a tank check valve for it.
The part is probably no longer available but is there a suitable replacement for it.
The top is a compression thread 5/8 inch OD. The threads into the tank are 3/4 OD.
It has a 3/8 ID hole in the side for connection to the unloaded valve on the switch.
Can send picture if it would help.
I have a Speedaire Model number 5Z639A 7.5HP Serial number 112995L-798329. I need to know how much oil goes in it and any other helpful tips to maintain it.
Thanks!!
I have no clue how to post a new thread.
I have a Speedaire Air Compressor built in 1976. Model # 1Z991D. Seems to work well. Pumped up to 100 lbs today after sitting for quite some time. Need to sell. Not sure of details of compressor. Size of tank or motor. Hooked to 220V. Would like ballpark value to sell it in Tucson metro area.
Anybody know?
I am looking for repair service in my area for a Speedaire 80 gal two stage air compressor. I’m in Soda Springs, Idaho
I have a 4B243A motor setup (3 HP, 14.1 scfm at 40 psi max 40 psi). It has a Dayton 9R730 motor and a VT470401 compressor pump (which i’m unsure if they are original to the 4B243A setup). I have a 5Z364A 60 gallon tank (rated 200 psi).
I acquired this setup when i purchased a new shop; was left behind by a previous owner. What i’m wondering is; with a tank rated for 200 psi; a compressor pump rated for 135 psi; and a 3 HP 3 phase motor; could i just swap the pressure switch out to something closer to 135 psi and have no issues? If so; are any of the genetic pressure switches suitable? Current there is a Furnas CW207571AV (on 30 off 40 psi) pressure switch on there. Which again; im unsure if this is original to the model number.
I have a speed air 5Z689A 2 stage compressor and often through the day the PRV on top of one of the cylinders will pop open for a split second just as the motors stop. Also you can sit and watch the pulley and motor rotate slightly on the same stage as the PRV, after the motor has stopped, as if the piston is moving on its own.
Thoughts?
We have two (isolated) 1WD61 Speedaire (champion) compressors. We have observed small issues on both units as follows:
Unit 1: Operates normally except that air bleeds from pressure switch during the first 30 seconds of the cycle. The bleed stops during the second half of the cycle and the unloader valve releases air as intended post-cycle. There is no continuous air bleed between cycles. Is this likely a failed unloader valve or a dirty check valve?
Unit 2: Cycles on and builds pressure normally at first filling. However under low usage the unit cycles on every minute with a short (6 second) cycle. This continues to happen at these intervals. I assume the pressure switch is activating too early (low end) and needs to be replaced. Does that sound reasonable?
Thanks.
I have a wheelbarrow model 1vn93 that runs great but only pumps up to between 20-30psi and no more. Any ideas?
We have a Speedaire Model 4B219, now discontinued, that blows the pressure relief valve every time the motor is about to kick off after reaching the specified pressure. The valve blows and the motor kicks back on. I have to manually shut the valve, but it will continue happening all day long if I do that. I have managed to make it work in the past by playing with the outlet pressure adjustment knob, but that is no longer working. They no longer make the pressure switch for this model to my knowledge. Do I need to replace it with an alternative or should I be looking at something else? Thanks..
I have a Speedair 5Z405D powered by 10hp lesson motor. Sometimes it runs ok but majority of the time it makes a grunting type noise followed by tripping the wall circuit breaker after the motor pulls near 200 amps. Motor and pump spin by hand unloaded fine. We have replaced all the capacitors, same issue. Any advise on how to check pump assembly for a restriction/high resistance? Anyone come across a similar issue?
Hello I have 1960 Speedaire air compressor I need a off and on switch and aluminum tubing and belt and also parts manual where I find these part’s at or what options do i have can I up date the part’s?.
I have a Speedaire 3z531 compressed air dryer. Any idea how old it is and what it might be worth assuming it still works?
I have an older Speedaire that stopped working. I loosened the belt and the motor runs freely, but I can barely turn the pump flywheel by hand. The single phase pump part # is 2Z498. Is it rebuild-able and if so where can I get instructions and parts for a model this old?
i have upright 60gl speedaire air comp. i know i need valve plate assembly, one of the thin pieces of metal broke off and comp will not build up much pressure.
numbers i found plate has a t00113
number under dipstick vt470401
other side of pump vto403
bought this new back in 1997
any help thanks
Hi-
I’m looking for a pressure switch for a Speedaire 3Z355 compressor. Any suggestions would be greatly appreciated.
I have a Speedaire compressor m. 2yj61, it. Keeps backfiring and won’t start.
I have a Grainger Speedaire Compressor and it’s been Tripping the Breaker after they first fill of “Air” into the Tank. I’ve Installed a New 15hp Motor and the problem is Still There. Im Going Back to Check some of the theories on this Page. I’ll Keep You Informed.
I have a 4 gal speedaire pancake compressor. Grainger model # 1vw40. I’m getting 120v into the pressure switch but zero volts on the “motor” side of the switch? I’m assuming the pressure switch is bad?? Can you help me locate a pressure switch?
Thanks,
Todd
I have an older Speedier 3Z420 – it builds pressure to about 22psi then slows down and stops. I changed the oil and plugged it directly into an outlet. any ideas??
I want to overhaul the pump on an old Speedaire 3Z745A-2. The pump is marked R158C-2 and has two breathers; one from the crankcase to the atmosphere via what looks like an oil dipstick tube, the other from the crankcase to the cylinder head via 1/4″ tubing. I have been unable to find a parts list for this pump. I will need rings, gasket set and reed valves. With respect to the valves, why would I need to replace the plates, assuming they are undamaged? Any advice/assistance you can provide would be very much appreciated.
I have a speedaire HD 095 RAD Upright single faze. With a 2 hp motor.
The start up is good but as it builds pressure it starts to bind at 35psi and wants to stop, so I turn it off before it trips the breaker.
It is hard wired no ext. cord.
