WALL VENT FRESH F100 dB Thermo Inner part

The Fresh F100 Thermo-dB replacement air vent automatically adjusts according to outdoor air temperature. The diameter of the round vent plate is 138 mm, and the depth of the vent unit in wall mounting is 44-58 mm from the wall surface, depending on the setting. The internal part of the vent is also suitable for a ventilation grille. The fixed pipe connection/outlet on the internal part is 45 mm long (75 mm total including the space required by the thermostat), making it well suited for insertion into a 100 mm duct. A general rule is to install at least one Fresh 100 Thermo-dB vent for every initial 20 m². The sales package includes the internal vent part with a G4 class standard filter, condensation insulation, and thermostat, along with a sound-dampening through-pipe Ø98/140 mm (length 400 mm), fixed cover plates 165x165 mm, pipe connectors, and an external grille 150x150 mm. The external grilles are available in multiple color options: white (included in delivery), gray, red, brown, black, and yellow (LVI 181703-181708). The vents are manufactured from environmentally friendly, recyclable plastic. Not consumer packaged. The F100 Thermo-dB is an easily installable replacement air vent. A general rule is to install at least one Fresh 100 Thermo-dB vent for every initial 20 m². However, the required number of vents is influenced by many factors, so the quantity should be verified by an HVAC professional. The vent is installed on the wall of living and bedroom areas, for example, above the window and above the heating radiator. This utilizes the warm convective airflow, allowing incoming air to enter as draft-free as possible. The thermostat reduces the air gap in the vent cover when the temperature drops below +10 °C. The cover closes completely at -5 °C. This default setting can be adjusted by rotating the vent cover clockwise or counterclockwise. One full turn opens or closes the cover by 4 mm, corresponding to a temperature change of approximately 4 °C. To restore the default setting, rotate the cover clockwise until you hear a faint click. The F100 Thermo-dB is suitable for gravity-based ventilation systems, reducing excessive airflow to an appropriate level during winter. Continuous airflow is possible by using an optional locking plate to prevent the vent from closing (LVI number 8823721). The locking plate is installed under the vent cover inside the thermostat housing; one locking plate enables a continuous basic airflow of approximately 2.5 l/s or 9 m³/h (10 Pa). The internal part of the F100 Thermo-dB (LVI number 8823715, unpackaged) is also suitable for a ventilation grille, featuring a fixed cover plate of 165x165 mm. The internal part can also be used to upgrade an old vent. The F100 Thermo-dB vent package is also available with a standard duct of Ø98/102 mm (F100 Thermo, LVI number 8823512).
