## Summary description

AWENTA ZZ100 is a white check valve for ventilation fans with a 100 mm diameter connection. Designed to prevent backflow and unwanted air infiltration in ducted exhaust or supply systems, it mounts inline with round ducts. Suitable for residential and light commercial ventilation installations where one-way airflow control and simple maintenance are required.

## Long description

AWENTA ZZ100 is a white check valve designed for inline installation in 100 mm round ventilation ducts. It prevents backflow and unwanted air infiltration in ducted exhaust or supply systems, allowing air to flow in one direction while closing when the fan is off or under reverse pressure. The compact cylindrical body and 100 mm connection diameter make it compatible with standard residential and light commercial ventilation setups. The valve is intended for applications where straightforward one-way airflow control and easy maintenance are required.
Advantages
The check valve provides reliable one-way airflow control without obstructing the duct's internal diameter. Its white finish integrates visually with common ventilation components and grilles. The inline design simplifies mounting in existing round ducts, and the mechanism closes automatically when the airflow stops, reducing energy losses and preventing odor or insect ingress. The construction supports routine inspection and cleaning when installed in accessible sections of the duct.
Suitable for
Domestic bathroom and kitchen exhaust fans with 100 mm ducts
Supply air systems in small apartments and houses
Light commercial ventilation where one-way airflow is required
Retrofit projects to prevent backdrafts in existing ductwork
Key specifications
Connection diameter: 100 mm
Colour: white
Mounting type: inline for round ducts
Function: one-way (check) valve to prevent backflow
Typical application: ducted exhaust or supply ventilation
How to use
Install the check valve inline in the 100 mm round duct with the valve orientation matching the intended airflow direction; ensure the arrow or flow marking (if present) points toward the exhaust or supply outlet. Secure connections with appropriate clamps or duct tape and confirm a tight fit to avoid leaks. After installation, run the ventilation fan and observe the valve operation to ensure it opens under normal flow and seals when the fan is off. Access the valve by locating it in an accessible duct section for periodic inspection and cleaning.
Usage recommendations
Place the valve in a straight section of duct where airflow is not obstructed and avoid installing it immediately adjacent to sharp bends or elbows. Regularly inspect for dust buildup and clean as needed to maintain smooth operation; in corrosive or high-humidity environments, check connections and seals more frequently.
