DOMUS Adjustable Air Valve Diffuser - 100mm - White

This DOMUS diffuser is designed for 100mm diameter solid ducting.

The product description specifies fitting into solid ducting, so it is not recommended for flexible ducting.

You can adjust the airflow by rotating the central disc of the diffuser. Clockwise typically reduces airflow, and counter-clockwise increases it.

Clean with a soft, damp cloth. Avoid using harsh or abrasive cleaning chemicals.

It is designed for fitting into solid ducting that terminates flush on a ceiling.

An adjustable air valve allows you to precisely control the amount of air entering or leaving a room, helping to manage ventilation, comfort, and energy efficiency.

The material is not specified in the provided information, but it is designed for durable use in ventilation systems.

Adjust the central disc of the diffuser. Turn clockwise to reduce airflow and counter-clockwise to increase airflow.

Check for any obstructions within the valve mechanism or duct opening. Ensure the valve is properly seated. Clean the internal surfaces if necessary.

Verify that the connected ventilation system (fan, HRV/ERV) is operational. Check that the diffuser is not fully closed and that there are no blockages further down the ductwork.

Ensure you are using a 100mm solid duct opening. Confirm that the ducting is standard and not deformed. Additional securing methods may be required based on your ducting installation.
