The ceiling-ducted ventilation system offers a cutting-edge overhead airflow solution tailored for modern residential and commercial environments. With its state - of - the - art airflow channel design and optimized circulation principles, this system operates almost silently while ensuring outstanding environmental comfort in homes, offices, and retail stores.
It adopts precisely engineered brushless motor technology, which cuts down energy consumption by 40% and provides a vibration - free operation. Moreover, the 5 - stage speed settings can be customized to meet various airflow requirements, whether it's for gentle air circulation or rapid ventilation.
The aerodynamically enhanced blades, combined with a noise - reducing motor housing, enable the system to operate at a noise level of less than 25dB, similar to the sound of rustling leaves. An anti - resonance mounting system further eliminates operational vibrations.
The housing is made of corrosion - resistant aluminum alloy, with an IP54 rating, making it suitable for humid or dusty conditions. A dual - layer thermal protection system automatically shuts off the power when there are abnormal temperature changes.
The modular components come with pre - drilled alignment guides and tool - free connectors, allowing for an average installation time of just 90 minutes. It is also compatible with standard 6" - 12" circular ducting systems, with necessary accessories included.
The ETL/CE - certified electrical system is equipped with automatic fault detection. The non - sparking motor design meets the requirements of Class 1 Division 2 hazardous location standards.
Phase 2: Unit Integration
Mount the primary ventilation module to the pre-assembled support structure using vibration-isolation fasteners (included), maintaining 3" minimum clearance from combustible materials.
Phase 3: Ductwork Interface
Align the directional flow indicator on the duct collar with the cabinet's exhaust port arrow mark. Engage the bayonet-style coupling mechanism with a ¼ clockwise rotation until the safety latch audibly clicks, confirming airtight sealing.
