This guide is for homeowners and building managers seeking a silent, energy-efficient ventilation solution. The Vent Axia Freshvent 100 Thermo Db offers all-year-round passive ventilation with no running costs, automatically adjusting its vent size based on external temperature. A potential consideration is its passive operation, which relies on natural air pressure differences and temperature gradients for ventilation.

No, the Vent Axia Freshvent 100 Thermo Db is a passive ventilator and does not require any electricity to function. It operates using natural air pressure and temperature differentials.
The built-in thermostat regulates a damper. The damper starts to close at 10°C and is completely closed at -5°C. It opens again as the temperature rises.
The acoustically damped pipe is included to minimize noise transmission from the ventilation process, ensuring a quieter indoor environment, especially in noise-sensitive applications.
The ventilator has a diameter of 150mm.
Yes, it is designed for all-year-round use. In very cold conditions (below -5°C), the damper will close to prevent excessive heat loss, while still allowing for minimal passive air exchange.
As a passive ventilator, the airflow rate is dependent on external weather conditions such as wind speed and temperature differentials. It provides a continuous background ventilation.
Ensure the external vent is not blocked. Check if the ambient temperature is below -5°C, which would cause the damper to be fully closed. Verify installation is correct and that there are no internal blockages.
Gently inspect the damper mechanism for any physical obstructions. Ensure the temperature is within the operating range for opening (above 10°C) or closing (below -5°C). Avoid forcing the damper.
Ensure the acoustic pipe is correctly installed and sealed. Check for any loose parts or vibrations in the ducting. Verify that the noise is originating from the vent and not elsewhere in the building.
Setup: The Freshvent 100 Thermo Db requires installation into an external wall or a suitable ductwork system. Ensure the mounting location allows for unobstructed airflow. The included pipe should be fitted to direct air and minimize noise transmission.
Compatibility: This unit is designed for integration into standard building ventilation systems. Its 150mm diameter makes it compatible with common ducting sizes. It is suitable for use in residential and commercial properties.
Care: Since this is a passive ventilation device, maintenance is minimal. Periodically check the external grille for obstructions (e.g., leaves, debris) and clean if necessary. The internal damper mechanism should also be inspected for free movement. A simple wipe with a damp cloth is usually sufficient for cleaning external surfaces.
