Interview with Marco Zambolin, Founder of Sintra
The Future of Airflow Management
Sintra embodies a paradox—actually, several paradoxes—that we cannot fully explore in this article, but which certainly offer an opportunity to restore value to one of the most overlooked elements of air distribution systems: the duct.
Often underestimated, the duct is at the core of Sintra’s work, a company that today stands as a high-level Made in Italy symbol throughout Europe. We are talking about the leading European manufacturer of perforated ducts for both air diffusion and air pulsion, specializing in large-volume space treatment.
Let’s start with an important point: Sintra offers a range of innovative technologies derived from the original MIX-IND® system, alongside more traditional Spirojet perforated ducts.
“We aim to give the market the freedom to choose between what we call a traditional solution—represented by Spirojet perforated ducts, among the best air diffusion systems available—and a cutting-edge alternative with specially designed ducts known as PULSORI®, which incorporate our patented technologies.
For more than thirty years, MIX-IND® has been supported by extensive field validation, making it suitable for practically any context today.”
The calm confidence with which Marco Zambolin presents the issue is striking—but well-founded: thirty-eight years of experimentation, field testing, and studies in collaboration with third-party institutions have yielded concrete, tangible results.
The application of PULSORI® perforated ducts effectively addresses some of the most common challenges in large-volume buildings: heat stratification and airflow control at floor level.
“We are talking about a system that is truly unique, because it is based on the application of a physical principle: the creation of a pressure field along the diffusion axis, capable of setting the entire ambient air mass in motion at the desired velocity.”
