By the time the COVID-19 pandemic hit, everyone had realized: Air purification is a crucial topic. Since 1993, PROAIR GmbH Gerätebau has specialized in this field and has found a way to offer its customers a highly effective air purifier — in the form of a water vacuum cleaner that uses patented lamella technology.

Thanks to the “L-Lamella”, it captures even the dust particles and viruses that a conventional water vacuum cleaner would normally release through air bubbles.

While vacuum cleaners typically rely on filters that can clog or even develop mold, the flagship product of PROAIR GmbH, a device called the DELPHIN, operates entirely without a filter. The reason for this is the “L-Lamella”, a special lamella developed by the company nearly 20 years ago. However, the Allgäu-based company hasn’t rested on this innovation alone — the DELPHIN has been continuously improved ever since. Over time, it has become smaller, more convenient, more durable, sturdier, lighter, quieter, and more powerful.

Lightweight Materials in Top Quality

All these improvements have been possible thanks to the company's strong culture of innovation. Employees are encouraged to contribute ideas — even those that may initially seem far-fetched. Valuable input also frequently comes from sales partners and dealers, often during face-to-face encounters.

To make the DELPHIN lighter and more durable, PROAIR GmbH collaborated closely with plastic suppliers when developing new lightweight components.

“Almost all our parts are manufactured in Germany. This ensures we receive and install only the very best quality,” emphasizes CEO Bernhard Grassinger.

Innovation Focus: Usability

For the company, innovation must always provide clear benefits without creating new drawbacks elsewhere.

“It’s important to us to develop innovations that genuinely improve the product in every way,” says Grassinger. Two aspects are always the primary focus: enhancing functionality and improving usability.

The latest breakthrough in usability has led to a new patent: a Twist Technology that significantly simplifies access to the water container — an impressive advancement that further sets the DELPHIN apart as a unique solution.
