WALL VENT FRESH F100 THERMO

The Fresh F100 Thermo is a reliable, high-quality, and long-lasting replacement air vent for wall mounting. The thermostat automatically controls the vent’s operation based on outdoor air temperature. The vent features efficient condensation insulation. The diameter of the round vent plate is 138 mm, and the depth of the vent body within the wall, depending on the setting, is 44–58 mm from the wall surface. The internal component of the vent (LVI 8823535) is also suitable for use as a ventilation grille. The fixed pipe connection on the internal component is 45 mm long (75 mm total including the thermostat’s required space), making it ideal for insertion into a 100 mm duct.

The sales package includes the internal vent component with a standard G4 filter, condensation insulation, and thermostat, along with through-wall pipes, pipe connectors, and the external grille. The through-wall assembly consists of modular pipes with inner/outer diameters of 98/102 mm, connected by push-fit joints.

The thermostat reduces the air gap in the vent cover as 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. Each millimeter the cover opens corresponds to approximately 1°C. One full rotation opens or closes the cover by 4 mm, resulting in a temperature change of approximately 4°C. To restore the default setting, turn the cover clockwise until you hear a faint click. Minimum airflow can be achieved by using a locking plate to prevent the vent from fully closing (accessory LVI no. 8823721). The locking plate is installed in the thermostat housing beneath the vent cover; one locking plate enables a continuous airflow of approximately 2.5 l/s, or 9 m³/h (at 10 Pa).

Installation

The F100 Thermo is an easy-to-install replacement air vent, comprising an internal vent with a washable G4-class standard filter, through-wall pipe, and external grille. A general rule is to install at least one Fresh 100 Thermo per 20 m². However, the required number of vents depends on many factors, so consult an HVAC specialist to determine the exact quantity. The vent should be mounted on the wall of living and bedroom areas, for example, above the window and above the heating radiator. This allows utilization of warm convective airflow, ensuring the incoming air enters as draft-free as possible. If the wall is thicker than 360 mm, the through-wall channel can be extended using a modular pipe (LVI no. 8823513); the pipe has a diameter of 98/102 mm and a length of 100 mm (cuttable). The external grille is available in multiple color options: white (included in delivery), gray, red, brown, black, and yellow. The vents are manufactured from environmentally friendly, recyclable plastic. The F100 Thermo wall vent is also available with a sound-dampening duct (LVI no. 8823716).

The recommended tools for creating the through-wall opening are the Fresh Cup Drill 108 mm (LVI code 7016815), the Cup Drill Extension 300 mm (7016416), and the Cup Drill Bushing (7016415). These tools work on various materials, including wood, plastic, aluminum, steel, stainless steel, brass, copper, and other non-mineral-based materials. Contact your dealer to verify suitable installation tools for brick or masonry.
