The Aprilaire® 6508KV, 6510KV kitchen ventilation kit is designed to locally provide make-up air to areas where high cfm range hoods (typically near 400 cfm or above) are used to prevent home depressurization and its consequences. When the range hood's fan is operating, a normally closed damper 8 or 10 in rounds - is powered open to allow make-up air to be drawn into the home. When the hood's fan is off, the damper is closed, preventing air from entering the home. The vent kit can also be tied into a HVAC system.
