HAND ME DOWN A SPEEDAIRE! ... might explode on me...?

by James

I just was given a Speedaire 2z498 from my uncle as a gift.. I've looked everywhere for the manual. My question is does this compressor have a cut off psi? I was worried that if I started working it might explode on me...

James, good on you for a freebie compressor!

Have a look at the page on this site PRESSURE SWITCH which will explain all about what they are and what they do. Your air compressor has one I'm sure, as I've never seen an air compressor without one.

Your compressor also has a PRV (pressure relief valve) and you might read that page too to see how this provides some redundant protection from a critical overpressure.

Cheers,

Bill

Gallons? - how to tell how many gallons it holds

by Scott Gala
(New Kent,Virginia,USA)

I have two compressors but need to know how to tell how many gallons it holds? Also I need to know what the max air it can hold.

The numbers Model #2Z499 (tank)\9K322J(motor)Ref#R603256J
Model number #3Z783 (tank)\6K773AB(motor) Ref#R6075738

If these numbers help any info would be great. Thank you for your time...

Scott, this is not a currently available model from Speedaire / Grainger.

The only photo I was able to find shows a tank that looks to be around the 25-30 gallon size. I can't see your compressor, so I don't know your tank size for sure.

Anyone else have any info on this compressor tank size?

Look under Tanks on the site map page for information as to tank size in CF versus gallons.

Cheers,

Bill

Portable air tank requirments

When am I required to replace my portable air tank?

Bill says...

I guess you are "required" to change it when it no longer holds air pressure?

If the question is, is there a law or regulation about them, I have not heard of one.
