Applications
HVAC and AHU Fans
In short: 5 series (33 models) cover 600–1,800 m³/h, up to 760 Pa static pressure for HVAC and AHU Fans.
Air handling units combine coils, filters, heat recovery and dampers, and the fan has to hold design airflow across all of them. Our EC centrifugal and double-inlet blowers are built for that duty, with speed control that lets the AHU follow real load instead of running flat out.

- Fan coil and VAV terminal units.
- Plate and rotary heat-recovery ventilation.
- Ducted fresh-air and exhaust systems in commercial buildings.
How to choose
Size on the total external plus internal pressure drop at design flow, then check part load: EC plug fans cut power roughly with the cube of speed, which is where most AHU energy savings come from.
Industry criteria, series picks and evidence
AHU selection is an operating-point decision: the fan must hold design airflow against a dirty filter, not just a clean one.
| Criterion | Typical value | Why it drives the selection |
|---|---|---|
| External static pressure | 250–700 Pa | Filter, coil, duct and terminal resistance |
| Airflow range | 500–2,500 m³/h | Per fan or per module |
| Filter loading | up to 2× clean resistance | Select at the loaded point to hold airflow over the service interval |
| Control | 0-10V/PWM or 3/4-speed taps | Taps for fixed duties, analogue for sensor-driven trimming |
