Default Attic fan for vent a hood

I have a commercial range - 185k BTU. I'm having a hard time finding a
hood vent that handles 1600 CFM. I found a 1600 attic fan at home
depot that costs $79. I was thinking of buying a nice stainless steel
hood and running 6" or 8" ducting from the hood, through the attic and
through the roof. Can I use the attic fan as an inline fan for the
hood vent, or is there some kind of special grease management used in
the vents you buy with hood vents?

Thanks.

The longer the discharge the less the cfm, best is out the wall near the
unit, you cant be looking to hard think of exterior mount commercial
exuast vents

Your not looking hard enough. I bought a hood for my last home that was 2000
cfm. Fortunately I decided to go with the remote mounted fan, lots more
$$$$. Still pretty noisey when on high.
You could actually see the steam rise into the hood when cooking. Sure made
a hell of a difference when we were frying stuff.

No don't use the attic fan, it will not be rated to handle the likely
grease and would be a fire hazard and likely a code violation.

You have a commercial range and you will need a commercial vent system.
Don't cheap out now. Also as noted, expect to use larger than normal ducts
and try to keep them short.



Exactly right. People who buy "commercial" appliances are often
surprised when they find that they have to also meet the commercial
building code requirements for venting and grease traps. Attic fans are
cheap for a reason -- they won't pull squat through a duct of any length
(that 1600 CFM will probably drop to 600 CFM), and they will be a hazard
if grease builds up on the motor. Some building codes require fully
welded metal ducts and a manual/auto fire protection system on
commercial appliances. Cha-ching!

The attraction to these types of appliances is a mystery to me because
most people will never cook meals like a restaurant kitchen does. I
wonder if the house has pipes and a gas meter that can handle the 185k
BTUs of the range and the 150K-250K BTUs of the furnace or boiler at the
same time? Restaurants have those huge gas meters and pipes for a reason...

Bad idea!
First an attic fan is not designed for this use. Second, if it was 8" duct
will not flow 1600 CFM with that type of fan.
How many fans do you want? Send me a CC number, I'll get you a fan!
Do you really need 1600 CFM?? What climate are you in? That 1600 CFM being
pulled out of the house needs to be replaced somehow! You will have air
drawn through every crack and opening in the house with the fan running.
Fireplaces, chimneys, water heater venting all will be flowing air the wrong
way bring exhaust fumes into the home when the hood fan is running! In the
heat of summer you will be bringing in hot humid air, winter, cold dry air.
1600 CFM of out door air at 80-90F will require somewhere around 8 tons of
cooling to keep up!
If you plan on running this hood allot, you have more problems than finding
a fan!!

Most of the time is "too stupid to know better and letting vanity be their
guide"

But some of the time it's due to the crappy output of most ranges. You're
right, of course, most folks will never need the sort of cooking features
commercial ranges provide.
