Fresh 80 DB Air Inlet
This product operates the same as the Fresh 80, but is larger and has insulation to dampen the sound.
Sound reduced wall vent designed to provide a continuous airflow into the building/house. The vent is supplied with filter and condensation protection. The vent can easily be open/closed with the pull cord. Minimum-flow can be set by adjusting the setting screw.
The Fresh 100 DB is also available for more air flow.
