okay John, 3100 cubic meter per hr.

I would really like to see what it takes to produce 3100 cubic meters/sec. Big LOL.?

this has been a point of interest for my nerd self. when i saw the AF22 spec (which BTW is 3100cubicm/s) it made me think diesel vs gasoline engines as a very loose comparison. high torque of diesel moves weight more efficiently than a gasoline engine. same HP diesel engine can have twice the torque. so just talking out loud.

i am trying to find torque vs current plots of 3ph and 1ph motors to see if i learn something.

Also Felder has proven over the years their actual specs listed in catalogs are up for debate as far air flow goes. Many misprint. Austria being a metric country calculate in Cubic Meters per minute which sometimes gets confusing for those accustomed to Cubic Feet per minute.?

3hp is 3hp, doesn¡¯t matter if it¡¯s a single or three phase motor. If the specs say the same CFM is accomplished, then the specs are most likely wrong, or they are using the same exact impeller and housing and the 4hp motor is essentially over kill for the application. Don¡¯t forget, Felder uses the S1 and S6 motor specifications, so hp is a relative term depending upon the rating of the motor¡­. the S1 3hp motor is the same as a S6 4hp motor. It is a marketing gimmick.

when i look up AF 22 on eshop there is something interesting. 3HP, 3ph moves same amount of air as 4HP, 1ph unit. anyone know if these specifications are correct?

i am interested in understanding if 3ph motor has advantage over 1ph. this might be a good example possibly showing (or not) that the higher torque of 3ph can do more actual work under load than a 1ph motor both pulling same current.

?I have an AF 22 for sale.? It can be wall mounted up out of the way and use just on bag to save space.
