harman distribution question

[Tonyray]

ok. original P61A blower was 0.8amp..dayton.
bought a spare few yrs ago which was the replacement at reputable pellet parts place.
noticed it is 0.7 amp.. all else is the same.. 1500 watt etc.. Fasco.

Also see that the newer replacements are 1.0 amp so question being will they push more air than the spare I bought back then or is amperage not a big difference you would notice in cubic feet per minute or speed, performance etc..

A 300 milliamp difference in rating probably won't amount to a noticeable difference in RPM. I wouldn't be concerned.

If the impeller blade or squirrel cage is the same size and the RPMs is the same then the CFM will be the same. The higher amperage is good because when the blades get very dusty and dirty then it will not slow down as much and move less air, it will have the power or torque like a car to be consistent. Since the difference is 10ths of an amp there is not much difference.

ok... makes sense to me...
