looking for a bigger cfm blower motor for a harman magnum coal stoker

[lime4x4]

I just got a harman magnum coal stoker i just think that the blower motor is under rated for this great stove. It comes with a 135 cfm blower fan. You would think a stove with this much btu output would have a bigger motor. So i was wondering if anyone knew of a source that has a bigger cfm blower motor? My dealer said harman doesn't make one but there might be a few aftermarket motors out that would work. I've seen units that were rated at 72K btu that come with a 265 cfm blower fan as standard with an option to get a 435 cfm fan.By the way this stove is capable of putting out over 85K btu

You could try looking into grainger. They may carry something a little bigger then what comes with the unit.

That is a really nice stove. I almost bought one but the size a the blower was a drawback for me. I went with the Keystoker and got it with the 500 cfm blower, as I too am running it in basement and pumping the heat upstairs. Might want to try to find a keystoker parts source and see if you could retro-fit the blower onto yours.

Just keep in mind that the faster the air travels through the ducting the faster the air is going to cool down. Easy rule - slower means warmer, faster means cooler.

Yeah and also installing a blower on your stove that is larger than the one that it was designed with might cool the firebox down resulting in improper burn, clinkers etc.
