Blowers n such

[Bret Daniel]

Hi,

Does anyone have a line on a used version of this?

http://www.grainger.com/Grainger/DAYTON-PSC-Blower-1TDP7

Or anything that is single phase, 110V/60Hz that will deliver upto
150CFM and has an opening of at least 2"x2"

Initially, was going to use the Kirby for the blower, but the noise
level is severe. A small blower as above could do the job nicely.

Will also need some assistance in creating a electronic RPM regulator
for adjusting speed, etc.

For the casting furnace.

FWIW, I have a copy of Dave Gingery's book on building centrifugal
blowers. But Tom can probably scrounge one :-).

The linked blower was the blower that Dan Dricken used on his furnace.
The cool thing about it was that it was really quiet. It was easy to
have a conversation near the furnace.

Looks like you could probably get by with a bathroom vent fan or two.  I use a couple of these fans to blow heat down my chimney that is cutoff in my attic.  It is basically using my attic as a solar heat collector.  It works pretty good in spring and fall.  The ones I have both pulled 50W though not ~80.

Controlling the speed of a 120V single phase motor is somewhere between tough and impossible.

I have a 12V fan like this I'll bring it.

When you build furnaces with a lot of back-pressure a higher static pressure blower is a good move. Look for blowers from high efficiency furnaces, they have the correct pressure ratings. As far as regulating the air flow a gate it the outlet works great. Many commercial furnaces admit the gas at the inlet of the blower to create maximium fuel/air mixing.

Agreed,

Blowers I have built int he past have all had a custom slide valve
(basically a metal plate that slides in and out to restrict flow).
Was thinking we may be able to build a trick blower control with our
collective electronics expertise.

A concept like:
Lighting the furnace speed: very low air flow to start the furnace
Opertating speed for propane setting/button
Operating speed settings for various waste oils mods, etc.

Possibly even contolling the fuel valve(s) as well.

I will update the WIKI page soon with addtional items.

Thanks for the input! The collective is good, the collective is
strong!

I have a High efficiency furnace that you can scavenge the blower if
you want it for free. But i have another suggestion. a Beckett oil
burner is like a 1/3 HP blow drier. Some heat/ac shops may give them
away. But you can pick them up for $50 - 100 when winter is done,
craigslist and Ebay. Remove the oil pump, and regulate air flow with
the air intake.
Good luck,
Matt

Or even keep the oil pump an burn bio diesel...
