Unique Benefits & Applications
✅ 1. Exceptionally Energy Efficient (EC Technology)
Unlike conventional AC motors, the EC-driven K3G250PR04H3 adjusts speed dynamically, ensuring 30-40% lower power consumption while delivering optimal airflow. The integrated PFC (Power Factor Correction) maximizes efficiency, reducing operational costs in 24/7 industrial applications.
✅ 2. Smart Control & Monitoring
- MODBUS-RTU compatibility – for integration into automated ventilation systems.
- 0-10V DC / PWM input – allows speed adjustment via external controllers.
- Thermal overload protection – prevents motor burnout in extreme conditions.
✅ 3. Robust Construction for Harsh Environments
- Galvanized steel casing resists corrosion in damp or chemically aggressive settings.
- IP55-rated protection ensures reliability against dust and water splashes.
- Ball bearings (40,000+ hours life) minimize friction and maintenance needs.
✅ 4. Low-Noise Operation (Ideal for Indoor Use)
With a 6-blade optimized impeller, turbulence is minimized, reducing noise below 65 dB(A)—perfect for HVAC systems, server rooms, and food processing plants.
