Hello visitor. Is this a change from how your air compressor worked before?

The part number you provided is that of the compressor pump, but is not the model number of the compressor. What HP is the motor on yours, please, and what is your tank size?

When you say "then air presure falls off fast when air tools are used" this may not be indicative of a problem, but simply the large demand of the air tool and the relatively slow supply capacity of your compressor. More info as a comment here would allow me to look further into this for you.

Cheers,

Bill

Information about a WW294-3

by Matt
(Fort Collins, CO)

I am looking for parts information about a 80 gal. Speedaire air compressor. The nameplate model number is WW 294-3,WWVR5-8,STR,GR with a SN# D012968. The close matches that I have found on Grainger are either 1WD58 or 1WD80. I am looking for manuals on both the compressor head or the entire unit. I am especially interested in a compressor head break down. Please let me know of any possible resources. Thanks for the help.

I am happy to post this for you Matt. Did you actually talk to Grainger? Sometimes they have info available that is not on their website. Otherwise, good luck in the search.

Cheers,

Bill

Hi Russell. I found some specs on your pump here:

www.grainger.com/Grainger/Two-Stage-Compressor-Pump-3Z174

Unfortunately, they don't answer the question.

Time to contact Grainger directly, I would think.

Cheers,

Bill
