Product Application
Range hood kitchen appliance features an all-copper precision motor, upgraded water curtain cooling system, high-quality double ball bearings, and aluminum housing. Compared to iron housing, it provides enhanced heat dissipation, oil resistance, and smoke resistance, with an IP54 protection rating. Ideal for kitchen ventilation, it operates stably with low noise and maintains durable airflow performance.
Technical Superiority
Performance Certification
IP54 Rating:
Dust ingress prevention (ISO 20653 compliant).
Water splashing resistance (tested at 10 L/min for 5 minutes).
Noise Control: ≤55 dB(A) at 1 m distance (meets GB/T 17713-2025 standards).
Airflow Stability: Maintains 95% efficiency after 3,000 cycles (18 m³/min baseline).
Upgraded Cooling System
Water Curtain Mechanism: Lowers motor temperature by 15–20°C through evaporative cooling, extending component lifespan by 2–3 years. Compatible with 5–40°C ambient temperatures.
Core Components
All-Copper Precision Motor: Ensures 20% higher energy efficiency and 30% longer lifespan than standard motors. Copper's superior conductivity reduces heat accumulation, critical for continuous kitchen operations.
Dual Ball Bearings: Minimize friction loss (≤0.5 dB reduction), supporting 15,000-hour continuous operation. Ideal for high-temperature environments (up to 150°C).
User-Centric Design
Scenario Compatibility:
Commercial kitchens (8–12 air changes/hour).
Home kitchens (≤6 m² space optimization).
Maintenance: Tool-free filter access, 30% faster cleaning cycle.
