WALL VENT FRESH F100 dB THERMO INNER PART

Thermostatically controlled renovation valve for replacement of an old valve or for installation in a ventilation grille when covering the installation opening requires a cover plate. The valve automatically adjusts according to outdoor air temperature. The diameter of the round valve plate is 138 mm, and the depth of the valve unit in wall mounting is 44-58 mm from the wall surface, depending on the setting. The sales package includes the internal valve unit with a standard filter, condensation insulation, and thermostat. Cover plate 165x165 mm. Packaged in bulk. The internal unit of the F100 Thermo-dB (8823535) is also suitable for ventilation grilles, provided there is sufficient space inside the grille for the thermostat to move (total clearance required: 75 mm). The internal unit can also be used to upgrade an existing valve. The internal unit’s pipe connection is 45 mm long and fits well into a 100 mm duct. NOTE: Ensure that the end of the existing duct aligns perfectly with the grille opening. If any gap remains, seal it with moisture-resistant silicone sealant, otherwise outside air may enter the grille, which is undesirable. If needed, you can extend the duct using a modular pipe (product 188010/8823513), which has a diameter of 98/102 mm and a length of 100 mm. The plastic modular pipe can be easily shortened by sawing or cutting. This product description is an automated translation of the original Finnish description.
