 I need a couple high flow eyeballs for fresh air 
ventilation (unboosted) coming through the panel. 
  
I would like to hear comments on which ones 
work/don't work.   I'm looking for: 
    - high flow rate 
    - stay set at desired 
opening 
    - stay closed when 
needed 
    - as little noise as 
possible 
    - smooth operation 
  
thanks,
