#1 Q:   Hi. Would the dual hood work with a renewaire ev90? If not which small Lifebreath would pair with this hood? Thank you
A:   The dual hood maxes out at 140 cfm and the EV90 typical range is 40-110 CFM per their specs. You should be fine.

#2 Q:   Can the lifebreath dual hood be used with Aldes h150trg HRV
A:   You are on the very upper limit with that HRV. The dual hood maxes out at 140 cfm and at that point has a 0.34 inch pressure drop on the intake. That is quite significant. You might be better off with 2 traditional 6 inch hoods.

#3 Q:   Can I just order the exhaust hood and not the entire kit?
A:   No. They come packaged and sold as a pair from the factory.

#4 Q:   Could I use the dual hood unit with an air exchange unit?
A:   Yes, the dual hood is specifically designed for HRV/ERV/Air Exchange units. Make sure the airflow/sizing is a match for the hood.

#5 Q:   Could 2 4 inch 200 cfm exhaust ducts be hooked up to dual hood??
A:   Theoretically yes, but not recommended. That hood maxes out at 140 cfm on manufacturers performance specs. Above that the pressure drop is very high. There could also be issues with water being sucked in.

#6 Q:   I understand the single pipe penetrating the exterior is 6, but what are the individual interior ducts? 4, 5, or 6?
A:   I presume you are asking about the dual hood. The interior duct connections are 5/6 inch, meaning either duct size can be connected. See the dimensions in the catalog sheet:

#7 Q:   Does the Dual hood come with an internal damper for intake/exhaust?
A:   There are no dampers in this hood unit. If one is desired on the output side, we recommend an inline butterfly backdraft damper in the line after the HRV, prior to the hood.
