Guys, I am not trying to make light of your concerns, but to me, they seem a tad unrealistic.
I have used a leaf blower/vac to suck up my leaves for as long as I can remember. And this is in a yard with 10+ big trees around it, resulting in huge piles of leaves and 50+ bags of copmpressed leaves per year. It usually takes a total of 10 hours or more to suck up all those leaves and empty them into the bags. I have never had a fire. And the bag has never even come close to breaking due to something coming out of the exhaust side at high velocity.
Joe, have you ever used a leaf blower/vacuum? If so, then you must know that there is an awful lot of fine dust in a leaf pile. I doubt that dry leaves and leaf dust is LESS combustible than sawdust; if anything, I would think it is probably MORE combustible.
Duane, do you realize that a good amount of things other than leaves get sucked up and spit into the bag (eg - sticks and even small stones)?
To me it seems like a leaf blower/vac is perfect for sawdust, especially when combined with a separator and then exhausting ot the window. Am I really that nuts?
