This 6 inch inline duct fan is designed to quietly ventilate hydroponic grow rooms, circulate fresh air, and improve airflow in enclosed environments. Ideal for grow tents, ventilation systems, cooling rooms, and air extraction, the fan maintains stable environmental conditions while operating with minimal noise.

Using a mixed-flow design and a high-efficiency PWM-controlled EC motor, the fan delivers powerful airflow while consuming less energy and producing less heat than traditional AC extraction fans.

Key Features

• Quiet grow room ventilation and air circulation
• Wired 10-speed fan controller included
• Compatible with intelligent environmental controllers
• Energy-efficient EC motor technology
• Mixed-flow design for high resistance ducting
• Detachable motor housing for easy cleaning

Performance Specifications

• Duct Size: 6 Inch
• Airflow: 402 CFM
• Noise Level: 32 dBA
• Dimensions: 7.9 x 12.6 x 8.4 in
• Bearings: Dual Ball Bearing

Precision Speed Controller

The included controller provides ten adjustable speed levels, allowing you to balance airflow and noise depending on your environment. The advanced PWM motor control allows the fan to run smoothly at extremely low RPM speeds without motor hum or vibration.

Backup memory automatically restores the last speed setting after a power interruption, ensuring consistent environmental control.

Quiet & Energy Efficient Operation

The mixed-flow impeller combines stator blades and hydrodynamic wind circles to maintain airflow even in high-resistance ducting systems. This makes the fan highly effective when used with carbon filters, long duct runs, or restrictive ventilation layouts.

Dual ball bearings rated up to 67,000 hours allow installation in any orientation. The housing is IP44 rated, making it resistant to dust and moisture in humid environments.

Applications

This inline extraction fan is suitable for a wide range of airflow and ventilation uses, including:

• Hydroponic grow room ventilation
• Grow tent air extraction
• Fresh air circulation systems
• Cooling equipment rooms and cabinets
• Bathroom and attic extraction
• Heating and cooling air transfer between rooms
