Technical Gurus

We are much more than a product manufacturer

We offer a broad spectrum of services to our customers; whether it is specifiers, installers on-site with screwdriver in hand or end-users who are asking us about replacing filters...

When it comes to domestic ventilation we have over 140 years experience so there isn't much we don't know about indoor air quality, mould and condensation and, overall, providing effective ventilation to homes.

Our longevity in this competitive marketplace means we have been responsible for many of the innovations that make today’s products so valuable to our customers. Today, yes we still provide products, but we also do so much more...
