The EC Motor Inline Ventilation Duct Fan provides high-volume airflow and precise climate regulation for indoor grow tents, hydroponic gardens, and residential/commercial HVAC systems. Powered by a three-phase PWM EC motor, it delivers robust airflow while remaining highly energy-efficient and quiet.
Designed for maximum flexibility, this series comes in three duct sizes—4″, 6″, and 8″—and can be paired with three distinct control systems, ranging from manual stepless dimming to advanced Smart WiFi App integration with real-time temperature and humidity triggers.

Key Features & Advantages
PWM EC Motor Performance Consumes up to 50% less energy than standard AC duct fans while producing higher static air pressure and lower heat dissipation.
Acoustic Noise Reduction Engineered with mixed-flow impellers and stator vanes to deliver maximum airflow velocity at ultralow sound levels (<35 dBA for 4″/6″ models).
Versatile Control Ecosystem Seamlessly switch between manual knobs and smart IoT climate controllers via standard 2.5m quick-connect signal wiring.
Durable & Compact Housing Built for easy inline installation into rigid or flexible ducting systems with minimal vibration.
Applications
Indoor Agriculture & Grow Tents: Exhausting heat, humidity, and odor; supplying fresh intake air for cannabis and horticulture.
Residential Ventilation: Improving air turnover in basements, attics, workshops, and bathrooms.
Commercial HVAC Systems: Boosting airflow in long duct runs, server rooms, and storage areas.
OEM Support
Customization (OEM/ODM): Private labeling, custom branding, customized packaging, and market-specific power plugs (US, EU, UK, AU).
