Airtècnics celebrates 40 years of innovation, commitment and global connections

Tuesday 29 September 2026

Airtècnics has built an industrial track record with international reach, grounded in innovation, in-house manufacturing and people, who have driven its growth from Castellar del Vallès, Barcelona. Its 40th anniversary has been an opportunity to look back and celebrate the journey we have shared.

Four decades of history, an outlook open to the world

With forty years of experience, a presence in more than 60 countries and a firm commitment to continuous improvement, Airtècnics has celebrated its anniversary with an international gathering that brought together distributors, employees, suppliers and partners.

The main events, held on 18 and 19 September, provided an opportunity to share experiences, strengthen relationships and recognise the people who have helped shape the company's history.

Castellar del Vallès was the main setting for the celebration, with visits to the headquarters and production plants, and events at Espai Tolrà and Castell de Clasquerí. The programme also included cultural activities in Barcelona, with Casa Batlló as another of the celebration's venues.

Gastronomy, tradition, music and special performances accompanied days of connection between people and cultures, reflecting the company's international scope and the bonds built over the years.

An industrial history rooted in Castellar del Vallès

Founded in 1986, Airtècnics specialises in the design and manufacture of air curtains, as well as ventilation, air treatment and air purification solutions.

Since launching its first air curtain, Windbox, in 1989, the company has expanded its product range and developed solutions tailored to its customers' needs, combining energy efficiency, design and architectural integration.

Rosenberg, a technology and commercial partner since 1993, has contributed to the company's development and international expansion.

Today, the Castellar del Vallès headquarters remains the hub of its industrial and technical activity. Engineering, development, production and research come together in facilities that turn know-how into proprietary solutions for projects around the world.

Forty years built on people

Airtècnics' journey has not been built solely on products, facilities or technology. It has been shaped by the people who work there, the partners who place their trust in the company and the relationships sustained over time.

<pThe 40th anniversary highlighted this human dimension. The programme made room for learning, fun and culture, as well as for conversation and for celebrating Airtècnics' ties with its international network. Some of the messages we received capture that spirit:

“Congratulations on the perfect organisation and on the original, surprising and outstanding ideas you presented!”

“Keep up the energy and vision! Thank you so much for everything!”

At Airtècnics, we would like to thank everyone who made this celebration possible: our international distributors, team, suppliers, partners, friends and family. Your support and trust over the years have enabled us to grow and take Airtècnics from Castellar del Vallès to the world.

Moving forward

This anniversary marks a milestone in our history and an opportunity to keep looking ahead. With a well-established international outlook, we remain committed to developing solutions that help improve comfort, air quality and energy efficiency in buildings.
