Ergovent frameless ventilation valve round 100 mm

The frameless ventilation valve can be integrated very tightly into the ceiling or wall, and should be plastered in for a seamless finish, so that it fits into almost any room and any interior style. It is a fairly new concept that fits in with people's desire for subtle, unobtrusive ventilation valves.

Please note:
The connection diameter is 100 mm, the total width is 238 mm.

Sleek design

This valve distinguishes itself from other valves by its end result. The product is fully integrated into the ceiling or wall and should be plastered in for a seamless finish. It is paintable, ensuring that after installation only a subtle slot remains visible in the ceiling or wall. In combination with the unique way of holding the middle cap in place with magnets instead of screws, no screw holes are even visible after installation.

Mounting

The valve is very easy to install by means of the supplied adjustable fasteners. This allows them to be adjusted and mounted with the self-tapping screws in the top of the plasterboard ceiling or wall. After installation, the valve should be plastered in for a sleek and seamless finish. The diffuser can be connected directly to a metal duct, via a flexible duct or to a connection box and is suitable for both supply and exhaust air.
