[Amps] Amps Digest, Vol 171, Issue 28

Mon Mar 20 00:15:42 EDT 2017

Try Grainger supply. If they don't have it they can usually get it.

The local Granger outlet has been good to me regarding onesy-twosey 
sorts of things.

However, FWIW I have two EBM-Papst G3G120-BB13-02 blowers which I got for a project which will not now happen :-) They are 120V which is one strike against them, but they are beautifully made. 142 cuft/min @ 0", 70 cuft/min @ 1.2". They are also quiet.
