Key Technical Specifications
| Parameter | EC/BLDC Ventilator |
|---|---|
| Applicable Systems | HRV/ERV, Duct Fan, Inline Ventilator, Bathroom Fan |
| Motor Technology | EC (Integrated BLDC & Controller) |
| Rated Power Range | 50W - 1000W |
| Static Pressure | Up to 800 Pa (High-Performance) |
| Control Signal | 0-10V, MODBUS, PWM |
| Speed Control | Variable/Stepless Regulation |
| Protection Grade | IP44 (Moisture & Dust Resistant) |
Core Competitive Advantages
- Highest Energy Efficiency (EC): Integrated electronics ensure motors run at peak efficiency across all speeds, achieving significant operational savings over AC alternatives.
- Seamless Building Management Integration: Native support for 0-10V and MODBUS protocols allows direct integration with BMS/BAS systems for centralized control.
- Compact Plug-and-Play Design: EC motors house the controller inside the motor housing, reducing the footprint and simplifying wiring for quick field installation.
- Optimized for Static Pressure: Designed specifically to maintain constant airflow volume even as filter loading or duct conditions change.
Installation & Environment Guide
- Typical Installation: Inline Duct Fan: The ventilator unit (containing the motor) is mounted directly into the rigid ductwork (e.g., in an attic or drop ceiling). Critical Step: Flexible connectors should be used to isolate motor vibration from the main duct run to minimize noise transfer.
- Scenario Optimization: Suitable for passive and low-energy buildings where precise air exchange rates and minimal heat loss are mandated by building certification standards.
- Visual Demonstration: Schematic showing an EC/BLDC motor in a duct fan within an HVAC system.
