Polypipe Ventilation has launched a new range of Silavent Intermittent Bathroom and Kitchen Fans and Sapphire Decentralised Mechanical Extract (dMEV) fans.


Our highly efficient NEW Sapphire dMEV range offers continuous low level ventilation – to a single wet room, coupled with virtually silent operation.

Stylishly designed to discreetly complement modern interior design schemes, our new dMEV Sapphire range offers exceptionally high levels of energy efficient performance and operates almost silently; ensuring homeowners are not disturbed whilst maintaining continuous and effective balanced ventilation.

Decentralised Mechanical Extract Ventilation (dMEV) systems incorporate continuously running extract fans, designed to remove waste and moist air from a single wet room.

As an added benefit to developers, specifiers and self-builders, incorporating a dMEV system will also help to lower a property’s Dwelling Emission Rate (DER) and therefore provide a higher SAP rating.


Silavent fans provide local rapid extraction and include axial, centrifugal and in-line options. Our Silavent fans have a superb reputation for reliability and ease of installation.

New to the range is the stylish Silavent Sapphire fans - they offer very quiet performance and the ability to mix and match fascia options.
