ventilation help for an aussie

[cindy79]

Hi guys,

Please help!!!!!!

i am in australia and having a bit of trouble with the tradies (workmen electrician ect) when i am talking about cfm, i think air velocity over here is measured in lites per min or per hour, i forget.

The last electrician i spoke to said that two bathroom fans in the roof above my torch would do and i had a hard time convincing my partner it wouldnt work.

I finally got my own way and am having a hood fabricated like the glasscraft hoods, can you please let me know if i am better off with an inline fan or a blower squirrell fan???, we are using the ducting to go up and out the roof, unfortunatley there are no windows in my garage and there is no other way but up. I have purchased 10" ducting and my hood is 1m x600mm. Would my correct cfm be around 650??

thanks for your help in advance

Squirrel cage blower is best performer in ventilation applications.... In line fans are for general vents over stoves or in bathroom areas to remove cooking odors or steam, where "just having some airflow" is desirable.
