Common Speedaire Compressor Problematic Parts

Pressure Regulator – For this air, compressor part helps to display, read, and maintains the air pressure and to function it works in combination with other parts, namely: the oil level and the tank gauge. The oil level as the name suggests measures the level of compressor oil, while the tank gauge measures the pressure level that is inside. 

Manual Thermal Overload Control – The work of this part is to override the controls once the compressor overheats or shows signs of overheating. The moment it is activated, there is no way you can turn the air compressor on until it sufficiently cools down. 

Safety Relief Valve – The common issue with this part is clogging/ corrosion. It is one essential part of the compressor that is responsible for pushing excess air out of the device to avoid it getting damaged.

Although luckily you may find spare parts you are looking from other places, Grainger has every solution you are looking for.

  1. I have a Speedaire compressor that I bought that was in great shape except one thing…no model number anywhere! So after a little while I finally figured out through CH that it was one they built. Model#3Z3xx.

    The “xx” is the part I can’t figure out since it is based on the HP. How can I tell if it is 23D, 55D, or the 95D?

    Thanks!

    • Hi Jason, To calculate the horsepower of your compressor you can use the watt meter. Plug the compressor into the watt meter, note the number of watts of power the device draws. For example, if the power is 1000 watts. Convert the power to horsepower by dividing by 745.8

  2. Some good basic info here. I have worked using Speedaire compressors and have worked on both industrial Speedaire units as well as two of my own. It is possible for a motor on a unit to be replaced with a different brand or even different horsepower. I had a customer bring me a Speedaire unit that had a pump that was designed for a 3 hp electric motor with an rpm of about 2750 with a 2.5” pulley on a 5/8” shaft. The motor burned out and he had an old motor laying around that would mount to the top of the horizontal tank. The pulley on it was 5” and the rpm was about 3250 which combined for an increased speed on the pump that was too much for it to take. When I attempted to dismantle the pump I was not able to slide anything off and I was not able to rotate the pump at all initially. It turned out the piston fused to the cylinder wall due to excessive heat/ friction from the increased speed placed on the pump. I ordered a generic pump for him designed to handle the specifications of his drive Unit and made all the necessary mods to the piping and replaced the check valve plus added another supply line off the opposing side of the tank for him that he wanted.
    I told him to make sure his oil stayed clean and to properly maintain his air filters and it should serve his needs for many years but most of all do not replace a motor with one that does not have the exact same specs and same size pulley. After he and his two friends got it loaded on his trailer and back to his shop and hooked back up he called me and said that it was working better than ever and it was quieter than ever. I charged him $114.00 for labor and the parts I sold at cost so he got a pretty good deal along with a lesson on making quick fixes to get a compressor going again. If he had consulted me I would’ve made sure the compressor pump did not operate beyond it’s safe speed. The generic pump was about $175 out the door and the check valve was less than $5.

  3. I have a Speedaire 3Z355H compresser. It works find, but recently started leaking air at the regulator. The part number for the manifold is CV219403AJ, but nobody seems to have it in stock.
    The center pressure knob on the regulator seems to be leaking….it has a threaded rod inside that screws down into the manifold. As I turn it, it leaks more or less, depending on how far I turn it. If I turn it clockwise, which I believe increases the pressure, it gets worse when I get it to the end (bottomed out). Under the knob is a plug of sort, that has a hex top. I started to loosen it, thinking maybe I can try a new O-ring. Air comes out really fast when I loosen a little.
    Do you know if some of these parts are rebuildable with generic parts such as o-rings? or is there a diaphragn or such factory part that could be the problem, and is not replaceable!
    This has been such a good compressor, and puts out more pressure than the current ones in this size. I just need it occasionally in my garage at home for tires, blowing off parts, etc. I don’t want to buy a new one.
    Sure would appreciate it if you could give me some tips, here….thanks!

    • With the cover of the regulator gauge assembly removed, as you have already done, you should note that the manifold is a series of fittings. By that, I mean, the form and function of the manifold can be duplicated, often with off the shelf brass fittings from a good plumbing wholesaler. Your only option, as I see it, is to acquire sufficient fittings to build a manifold, containing an new general purpose regulator as the core, thus resolving your failing regulator problem. I know of no source to get parts for these low cost regulators.

    • If you are talking about the air intake filter, visit any compressor store that sells intake filters, and find one that will fit the port on your Speedaire compressor. I expect that’ll do just fine.

    • The first stop is to contact Grainger as Speedaire is their house brand and they may still offer repair kits. Depending on what you intend to rebuild, I just did a search for a Speedaire 2Z499A air compressor and found a number of sources for parts.

      Some of the rebuilding will require OEM parts that are sized for this compressor. Other parts that are not OEM can be used sometimes as well, depending, again, on what you are changing out.

      The valves are proprietary, though some folks have built their own. Same for the gaskets. About-air-compressors.com has a lot of info available about Speedaire air compressors.

  6. I have a whole unit speedaire 2z499b.

    the head is no good. the rest is in great shape.

    im willing to trade or sell.

    • Chris, I was unable to find any information on your 2z880a compressor. That it’s a 12 volt unit though suggests that it may have been designed as a tire-pump compressor, or one to fill up basketballs etc.

      Without knowing the specifications, (pressure output and flow) I cannot say what other uses it may have.

      If it is a compressor for filling tires etc., as to value, new, maybe $15???

    • Drew, did you ever locate a parts listing for your compressor? I just ended up with the same model and there is very little information online about it.

  10. I am trying to find parts and visual manual to help identify parts for a speedaire model 3Z406E. Your help is greatly needed and appreciated.Thanks Clyde

    • Shiv, it isn’t necessary to purchase a Speedaire gauge to replace that brand on your air compressor. You simply need to buy one that is the same size (liikely 1 1/2″ in diameter) with either a back mount or bottom mount that is the same as yours, and one that offers the same (or close) pressure range.

      Here is much more information about air gauges. Just click the link to Gauges.
