Want to buy new blower for range hood

[output123]

I have a 30" wide old range hood and I want to buy a new blower to make this hood good for a kitchenaid gas stove. The old hood has about 24" height, but it has a small motor inside and a lot of room for anything I want put on it. Can I buy a new blower and the filter to make it become a reasonable range hood.
What is the good place to buy the blower and filters?
and how to paint it to look like stainless steel?
Thanks.

Hi output123,
- I would look in the bathroom fan area and see if any fit your specs. These are essentially the same as range hood fans,only differently mounted. Another option may be an inline fan, constructed to fit inside ducting. There are many available of all sizes and cfm outputs. :cool:

Do it Right - Do it once.

if I am looking for something that is about 400cfm to 600 cfm, and want motor with the ball bearing to reduce noise, also where is the place to buy those mesh filter? any suggestion.
Thanks

Sorry, not a dooable project.

Kitchen exhaust hoods come with removeable blower wheels and motors but the housings are part of the hood.
In order for the fan to work it has to have a very close clearance to the housing which cannot happen if you use a bigger blower wheel.

Added bonus to replacing it is you can just buy a stainless one as any paint you put on it wouldn't last long at all.

after a lot of search I find 2 solutions that is interesting,
1. buy a exterior blower from Broan 331H it is about U$250 and it suppose to be quiet and very powerful, up to 600cfm, but the spec ask for 10" duct, but I think 6" should be good for me. But I need to buy a variable speed control to control the motor speed, any suggestion on what to buy.
2. buy a interior blower Broan P5 and it is $199 and it is also 600cfm
anyone use this before or have any comment on this design.
Thanks.

Either one would work but have different considerations.
The outside fan by far is a more deluxe solution but is more costly.
You must use the size duct that is recommended because it will both reduce the capacity considerably and would be quite noisy due to increased velocity and cavitation of the fan blade due to being starved.
Plus you would need to have a hood that had a filter set up capable of this velocity.

By far the simplest and cheapest, but a bit noisier, is just replacing the whole hood.
