Craftsmanship in air ducts
From a driven start to a trusted name in professional air handling.
How it started
DWJ-AIRDUCTS was founded in 2005 by Patrick Van Lessen with one clear goal: to manufacture high-quality air ducts using innovative methods.
What started small grew into a dynamic B2B reference in the Benelux. Today we make ducts and fittings in galvanised steel and stainless steel for customers across a range of sectors.
We believe in short communication lines, online applications and a personal approach. That is how we build lasting partnerships together with our clients.
