This Emglo pump is mounted on my new very old Rol-air w/8hp kohler and wondering how to find the cfm's rating? I can't tell what year it is and would like to know but searching found nothing, this was a barn find I was told. Thx , Bill

Get your calculator handy

Wow, long-shot here but if the tags/badges I see in the pictures DO NOT offer any cfm data, do they at least (possibly) speak of a bore and stroke of the piston/cylinder?

If we know the bore/stroke — and we know the rpms of the 8-hp motor, we could calculate the approximate cfm.

This is why I'm admitting this is a long shot. That's A LOT of work, to calculate the cfm.

Another method is to get a vessel which is filled with a known amount of water - but sealed — except for an air line IN, and a means to capture any water displaced by the incoming air from the compressor.

Capturing the displaced water into a measuring vessel once the compressor is ON — while clocking the water displacement for exactly one minute — will give you an indication of volume displacement within a minute.

From this measurement you can extrapolate a cfm measurement.

Compression of the air BEHIND the water might throw-off/skew the results a bit, but at least you can gain some idea of cubic feet per minute (cfm) rate.

I know of no other means by which to assess its volume/capacity.

found some info
by: Bill K

Since posted i found the pump should put out around 8cfm and the Rolair and motor are 1979 but unsure of pump itself? They told me the Emglo pump was not original to the unit but it is compareable in cfm and size. Anyone know how to tell year of mfg. with model and ser. no.? Emglo mod. KU SN. A-092183133. The guy at Emglo didn't know cause of being older..
