DAST technology – Efficient air humidification redefined

30% more humidification & 30% less power consumption – unique worldwide

DAST (Direct Air Stream Technology) represents a new dimension in natural humidification. Based on proven evaporative technology, DAST combines maximum efficiency with impressive performance – in a way that's unique worldwide.

Thanks to the targeted airflow guidance through the evaporator mat, DAST technology achieves up to 30% higher humidification performance compared to conventional systems – while simultaneously consuming 30% less energy . This outstanding energy efficiency is not only good for the environment but also measurably reduces operating costs.

And best of all: This efficiency is achieved with just a single evaporator mat – a milestone in technological development that is unparalleled worldwide.

How does DAST work?

With DAST technology, the airflow is drawn in via a highly efficient DC fan (direct current fan). This fan is not only whisper-quiet but also significantly more energy-efficient than conventional AC fan motors – ideal for continuous operation in sensitive environments such as living rooms and bedrooms, offices, or medical facilities.

Instead of swirling the air inside the unit—as is common with conventional evaporative systems—DAST channels the airflow directly onto the evaporator mat. This efficiently utilizes the entire surface of the mat, eliminating energy loss due to scattering within the unit.

This targeted airflow not only ensures maximum moisture release , but also particularly uniform and hygienic humidification in the room. The controlled direction of the airflow also prevents unwanted or inefficient release of moisture into the environment – ​​a crucial difference compared to conventional technology.

The advantages at a glance:

✅ +30% humidity performance – noticeably better air quality & indoor climate
✅ -30% energy consumption – economical and sustainable at the same time
✅ Only one cartridge – easy maintenance, fewer consumables, more efficiency
✅ Natural evaporation – hygienic and without additives
✅ Quiet & powerful – ideal for living rooms, offices or medically sensitive areas

Why DAST?

DAST represents a new chapter in indoor air care . The technology combines ecological responsibility with technological sophistication – developed for those who don't want to compromise on air humidification.
