Expansion tank fi125-2x75 VPB125-2

Ventilation expansion box

This expansion box from Awenta, model VPB125-2, is a key element in ventilation installations, allowing the connection of two 75 mm diameter ducts to a 125 mm diameter channel. It is ideal for connecting anemostats in residential spaces, such as bedrooms or living rooms, where balanced air exchange is important. The design allows for flexible mounting – on the floor, wall or ceiling – adapting to different types of substrate: concrete or plasterboard.

The box is made of durable HDPE polyethylene, which guarantees long-lasting and trouble-free operation. The addition of Nano-Silver bacteriostatic agent provides a high level of antibacterial activity, which translates to hygienic use and improved air quality. This makes the solution particularly recommended for people who care about health and comfort in their homes. The connection sleeves are equipped with seals and pipe protections, ensuring the tightness of the installation at class D level. Adjustable mounting brackets make it easy to precisely fit the box to the installation location.
