All-Copper Precision Motor and Dual Ball Bearings in Cabinet Centrifugal Fan for Enhanced Kitchen Ventilation
Product Overview
Engineered for superior culinary environments, this advanced ventilation system integrates a pure copper-core motor with a next-generation hydro-cooling module. The aluminum alloy construction delivers 40% improved thermal management over traditional steel housings, while dual ceramic-coated ball bearings ensure frictionless operation. Certified IP54 for dust/moisture resistance, it excels in oil-rich atmospheres with ≤55 dB whisper-grade acoustics.
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).
