Product Part Number

VS-125-GPV

Product Overview

The VS 125mm Plaster Circular Diffuser provides a discreet, frameless air terminal for modern ventilation installations. Designed to be integrated into a plasterboard ceiling or wall, the diffuser can be plastered and painted to match the surrounding surface, leaving a clean circular opening visible after installation.

Suitable for supply or extract ventilation, its circular design distributes air neatly while maintaining a minimal interior finish. The diffuser connects to 125mm circular ducting and can be paired with the compatible VS-125-FFCD foam damper where additional airflow regulation is required. Circular plaster diffusers of this type are commonly suitable for both supply and extract systems and are designed to form a permanent, flush connection with the surrounding plasterboard.

Frequently Asked Questions

  • What’s the difference between a supply air valve and an extract air valve?

    Supply valves introduce fresh air into habitable rooms such as bedrooms and living areas, while extract valves remove stale or humid air from wet rooms such as bathrooms, kitchens and utility rooms.

  • Can the airflow through an air valve be adjusted after installation?

    Many ventilation valves allow airflow to be adjusted after installation, although the method depends on the valve design. Final settings are normally established during system balancing and commissioning.

  • Are ventilation air valves available in different colours and finishes?

    Yes, air valves are available in a range of designs, materials and finishes, including discreet and decorative options intended to complement different interiors.
