        Q:Is there a chance of the damper doors possibly sticking shut if this product is used in a range hood application because of greasy exhaust build-up over time? What is the minimum required exhaust CFM that will cause the doors to open?
        by|Dec 17, 2020
        1 Answer
        Answer This Question

        A:  The KOM 200 U opens at 25 cfm @ 0.05 and 50 cfm at 0.1 static pressure. Using the KOM -U series with a Range Hood System should not affect the damper’s performance. The range hood filter usually does a good job preventing the presence of grease and dirt in the ductwork or on the damper. Please contact customer service they will fully resolve this issue.

          Works great. Not exactly compatible with other sheet metal but make a strap to go around both this and your existing sheet metal and you are good to go.
