Fresh Air Intake Units: Air Exchangers
Tjernlund FAI4 Fan Powered FRESH AIR Intake. Includes Exterior Wall Vent Hood and Intake Fan in Connecting Collar with Power Plug. Rated 75 CFM.
Fresh Air Intake Units provide fresh, outside air to replace air vented by Exhaust Fans and fuel burning Furnaces. Fresh Air Intake units are fan powered and bring outside air in on a demand or timed basis. Today's tight building construction limits natural air exchange and ventilation needed for healthy Indoor Air Quality. Fresh Air Intake Units reduce potential Carbon Monoxide problems. Fresh Air Intake Units can be used with an Exhaust for a complete air exchange.
