Ingersoll Rand 2420n5

[nbaker87]

I just inherited an ir 2420n5 atop of an 80 gallon tank, problem is there is no motor on it, from what little info I can find is should be a 5hp but doesn't say if it's a 3450 rpm or 1725 rpm... Also what the motor pulley diameter should be on said motor, can't find the rated rpm for the compressor head either! Thanks for any help you can give.

typically compressor heads want around 900 rpm
there is an online calculator that I find very helpful in determining pully sizes https://www.blocklayer.com/pulley-belteng
