For venting: 640 CFM range hood or 630 inline blower?
Ok, total amateur here, trying to set up an inexpensive, but effective vent system.
I have done all the calculations, and I think I need for a 30"x20" range hood size hood: 5 feet of 6" ducting with 2 ninety degree elbows:
around 600CFM blower/fan.
I have found brand new high-drawing range hoods between 630 CFM and 700 CFM for $120 to $135.
I have also found an inline blower at 630 CFM designed for venting hydroponic greenhouses, lightly used for $150 to $175.
Do you think the 630 or 700 Range Hood with 6" ducting will work for a ventilation system? Do they draw as much as they are rated to?
Rangehoods are Milano brand and Cyclone brand - don't know either company - don't know if they are knockoffs at this price, but they have no side baffles, so I will be adding them.
Inline fan is Ostberg brand.
Any thoughts?
TIA
p.s. I'm in Canada and it seems hard to find reasonably priced inline fans - especially squirrel cage - for a good price!
