The place for info on older Devilbiss compressors.

It turns out DeVilbiss in the USA is no longer in the compressor business, but their former Canadian operation still makes some DeVilbiss models and supports a lot of the older ones. They were able to help me out (see previous post). Those with older models might want to bookmark the site.

Wow. I thought DevAir was a US company with a branch plant in Barrie. They really did a number on poor old DeVilbiss when they sold it off eh? Too bad. They were as common as blades of grass in their day. The current DeVair pumps are as good though. I would not hesitate to buy one. They are the brand we sell at work

I have an older devilbiss compressor that was recently taken out of service since it was considered to be at the end of its "life cycle" and no longer deemed reliable. I am trying to find an owners manual or spec sheet on it and so far I have not found a thing. The compressor is rated for 80psi at 900 rpm continuous, though it can produce 150 at 750 rpm if you can stand the wait. It is a single stage (I think), two piston model, with an 18 inch flywheel (17 inch pitch diameter). The pump itself has a tag stating model "130" and serial number 352871. The tank has two other tags: 1. stating the UNIT as ULB-5292
2. various information such as: CRN# C1646-5036724819
IND SR#161294
A212GR B TS 70000
MWP 200 TEMP 650
T.SH 130T HD 115
U C 1966

If anyone has information (SPECS or OWNERS MANUAL) on this unit or knows where it can be found, I would greatly appreciate it.
Thanks Mike

I too have a model "130" pump, did you manage to find any specs on this unit?
Im very interested

Cheers

Justin

No specs yet. I stripped it down and found it is a single piston model. A good cleaning of the valves and head, as well as checking all conections and seals have made a bit of an improvement in function. It is a good solid pump but it was being under powered by using too small of a pulley on the motor. I have since remedied that. The couple of places that I have heard back from have all indicated that this is an older pump and parts (new) are no longer available. My pump was produced in 1966. Good luck.

Good to hear, definatly looks solid allright.
Is yours operational then?
If so is it managing to run most tools?
I need to run a good 15cfm.
I bought a tank and this compressor turned up with it, so i wouldnt mind using it if it will do the job.

Cheers

Justin

I have run a couple of time tests and have found that my pump runs a very consistent 12 CFM (at mid PSI's) which drops to around 10.5 CFM once it reaches higher PSI's. Currently it is powered by a 5HP 22 amp motor but when it was powered by a 1.5 HP 9.2 amp it would fill a 35 gallon (US) tank to 130 PSI in 245 seconds. This gives it a CFM profile of 10.47 at final stage. At low pressure it starts off at about 15 CFM. The compressor profile would be 18 inch flywheel (17 inch pitch diameter), motor RPM 1720, and motor pully 8.75 inch diameter (7.75 pitch diameter). This turns the pump at approx 785 RPM. I could run the pump faster (it's rated for 900 RMP) but it is old and I have found this to be sufficient to run my greediest tools. The larger motor does not really change the CFM profile but it does allow me to run the pump constantly with out having to shut down the compressor due to thermal shut down on the motor.

It may be old but this is a very strong compressor (provided it is in good shape). I have found it to be able to run any of my tools, from impact wrenches to cutters to a pressurized sand blaster. I don't know if you have the original spec tag from the pump but if not the max RPM is rated at 900. I've been running it at about 700-715 RPM and it will keep up to the CFM of anything I've tried so far (even the sand blaster). My only sugestion is that you invest in a large enough motor. I was using a 1.5 HP /1720 RPM comercial unit rated - 230 volt / 9.6 Amp and the motor would eventually shut down (thermal protection) because it ran too hot. I replaced it with a 5 HP / 3450 RPM rated - 230 volt / 23 Amp and now I have power to spare. All this is on a 35ish gallon tank. If you have a lager tank you may be able to make do with a smaller motor since your tank won't empty itself as often, so the motor will get a break. As a side note, I will say that the unit ran well with the 1.5 HP motor until I wanted to use it for sand blasting. Sand blasting uses huge CFM. I did some calculations when I had my unit apart and I think it produces about 18.5 CFM @ approx 750 RPM. I have included a link to a site that has some useful formulas for setting up a compressor system. Again, good luck.
