harman distribution blower question

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..

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 etc.

 

I wouldn't be concerned, not much of a difference really.
