Rangehood necessitated ceiling drop box, exterior blower keeps noise low
David Woo Designs
The Cirrus range hood by Best is larger than the 36" Bluestar range enabling it to function extremely well even though it is 52" above the range surface. We did not want a traditional suspended range hood to block the view from around the island and we certainly didn't want diminished fume removal performance. The Best range hood accomplished this in part by choosing an external blower that is well over rated for the setup at 1500 cfm. The only draw back was the additional cost of a make up air system that was built into the forced air heating system of the house located in the garage. The make up air damper automatically opens when the range hood drops the pressure in the house by 0.2PSI. The over rated external blower rarely needs to be run at the top speed of four levels and means the hood operates at very low sound levels. This benefits the kitchen and the bedroom above the kitchen. Normal conversation is not hampered at all with the hood on maximum and is barely noticeable on low.
