Air purifiers are essential for removing dust, pollen, and spores from indoor environments. At Longwell, we provide the technology that ensures these purifiers operate at their highest efficiency.
A fan pulls air from the room into the device, where various filters clean the air. Another fan then returns the purified air back into the room. This process demands particularly quiet fans that can be precisely controlled to adapt to different conditions.

The advantages of fans from LONGWELL in fan coil units:
- Low noise emissions thanks to aerodynamically optimized fans
- Reliable operation with low risk of failure
- Robust design with rigid, aerodynamically shaped plastic housing/li>
- Infinitely variable speed control
- Simple commissioning, as motor, electronics and control system are all from the same supplier
