Dodge Posted March 16, 2009 Share Posted March 16, 2009 Anybody know anything about this blower?? It blows fine but not sure if its powerful enough for a gas forge blower. It doesn't blow near as strong as a hair dryer but I don't know what a blown burner requires. Hate go to the trouble of fabbing a 2 into 1 manifold if its an inadequate blower. I got it with a bunch of "stuff" that was otherwise going to the dump LOL. I googled it and came up empty but here are the specs from the ID plate: Redmond Co. Mod 3743 115 V 60 cyc 1570 rpm .3 amps type "L" 22 watts Ser# 12Q37996 Oil every 6 mos sae 20 wt HP wasn't stamped which is why CFM rating may be difficult(?) Fans 3.5" x 1.75" Ports 2" I.D. Thanks for any input, Scott Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 16, 2009 Share Posted March 16, 2009 You got me there. Might try hooking them up and seeing how long it takes to fill say a 30gl. trash bag. Then you can calculate how many BTUs per hr. it'll produce using 17.5:1 for the air to propane ratio and 95,000 BTUs/gl for propane. On the other hand you could just make a pair of disposable burners from exhaust pipe, plumbing pipe or even tin cans, plumb in a propane jet and see how it does. Gun burners are easy to tune.
