One should be careful when using the small backpack type blowers as they
often send the exhaust gases down the blower tube. Hence the honey becomes
contaminated with CO and petrol residues. I purchased a Homelite last season
and had to modify the exhaust. I would like to try the electric blowers and
have the generator on the truck and NOT have 2-stroke fumes all over me all
day long.Does anyone know what cfm is needed to remove bees from supers on a
commercial scale? Peter.
