The Panasonic Passive Inlet is an essential installation tool for your ventilation systems. The inlet vent has many properties that may benefit your application. The passive inlet allows your ventilation to provide makeup air to help balance indoor versus outdoor pressure. The makeup air allows to introduce fresh air from the outside, replacing the air exhausted by the ventilation fan. This replacement of air keeps humidity levels relative, and maintains a healthy atmosphere. The Panasonic FV-GKF32S1 features a foam pad to reduce outdoor noise and condensation, an insulation lining, a 3-inch diameter, 12 inch in length through-the-wall sleeve and 7 stainless steel installation screws. The FV-GKF32S1 can be set with three positions: Closed, 12 and 18 CFM. Other great features of the FV-GKF32S1 are the washable air filter, 2 position air delivery, a durable open/close levr and a bug screen. Installation of the FV-GKF32S1 requires a 3" wall opening diameter. All these great features of the Pansonic FV-GKF32S1 Passive Inlet are backed by Panasonic's 3-year limited warranty.
