The 4-Inch High-Performance Inline Duct Fan is designed for efficient ventilation and climate control in grow tents, indoor gardens, hydroponic systems, mushroom cultivation areas, and other controlled growing environments.

With an airflow capacity of up to 452 m³/h (approximately 266 CFM), the fan provides powerful air extraction while maintaining a compact 4-inch form factor.

The included variable speed controller allows the airflow to be adjusted according to the size of the grow tent, plant growth stage, temperature, and humidity conditions. This makes it suitable both for continuous low-speed ventilation and stronger extraction when additional airflow is required.

Key Specifications:

• Duct Diameter: 4 inch / 100 mm
• Airflow: up to 452 m³/h / approx. 266 CFM
• Fan Speed: up to 3300 RPM
• Power: 19.2 W
• Voltage: 24V DC
• Variable Speed Controller Included
• Compact inline design

Ideal for:

• Grow tents
• Indoor gardens
• Hydroponic systems
• Mushroom cultivation
• Propagation areas
• Small grow rooms
• Intake and exhaust ventilation

Benefits for Grow Tents:

• Removes excess heat generated by grow lights
• Helps control humidity levels
• Provides continuous fresh-air exchange
• Reduces stagnant air inside the grow tent
• Adjustable airflow for different growing conditions
• Can be connected to 4-inch ventilation ducting
• Can be used together with a compatible 4-inch carbon filter

The adjustable speed controller makes it easy to balance airflow and noise depending on the requirements of your growing environment.

A powerful and compact ventilation solution for growers who need significantly more airflow than a basic 4-inch booster fan.
