## Long description

AWENTA ZZ125 is a white 125 mm check (non-return) valve designed for use in ventilation duct systems. It prevents backflow of air when the fan is off, helps maintain the correct airflow direction and reduces unwanted drafts. The product is intended for use with 125 mm ventilation fans in residential and light-commercial installations to support efficient ventilation and occupant comfort.
Advantages
The check valve provides reliable one-way airflow control without electricity or moving parts that require power. Its compact design and standard 125 mm diameter enable straightforward integration into existing ductwork and fan outlets. The white finish offers a neutral appearance suitable for visible wall or ceiling grilles and indoor mounting. By limiting reverse airflow, the valve contributes to lower heat loss and prevents transfer of odors between rooms.
Suitable for
Residential bathroom and kitchen ventilation with 125 mm ducting
Ventilation exhaust outlets where backdraft prevention is required
Light-commercial ventilation systems such as small offices or service rooms
Retrofit projects replacing or upgrading existing 125 mm fan outlets
Key specifications
Diameter: 125 mm (intended for 125 mm duct systems)
Type: check (non-return) valve for ventilation
Color/finish: white
Material: durable plastic suitable for indoor ventilation use
Function: prevents reverse airflow and reduces drafts
How to use
Install the check valve directly onto the fan outlet or into the 125 mm duct run, ensuring a secure fit and correct orientation so that the valve allows airflow in the exhaust direction only. Attach with appropriate clamps or sealants according to duct type and mounting location. Inspect the valve after installation to confirm the flap opens freely when the fan runs and closes when the fan is off.
Usage recommendations
For reliable performance, ensure the valve is installed in a straight section of duct where airflow is unobstructed. Periodically check for dust buildup or damage and clean with a dry cloth if necessary. Do not expose the valve to temperatures or chemical environments beyond typical indoor ventilation conditions.
