Product review (5 stars): Almost sucked the dog off the floor
This thing is great.  And for anyone looking for blowers for Viking or Five Star hoods, this is exactly the same model for less than half the price.  You will need to buy or make the sheet metal cover and cord.  I went and got one from Viking parts because I needed it right away, but cutting a piece of wire and a small square of sheet metal should be easy for anyone who is handy
