About This

This 4-inch inline duct fan delivers 260 m³/h airflow with 2600 RPM motor, engineered for efficient air circulation in grow tents, hydroponics, and enclosed spaces. Its balanced blade design ensures smooth operation while managing humidity, temperature, and airborne particulates for optimal plant growth environments.(Note: It does not include pipes.)
Ultra-Quiet 30dB Operation: Precision-molded PP blades and vibration-dampened motor achieve noise levels as low as 30dB – quieter than a library whisper. Maintain discreet ventilation for residential spaces without disrupting daily activities or sleep cycles.

Smart Speed Customization: Integrated inline speed controller allows airflow adjustment from 30% to 100% capacity. Fine-tune ventilation intensity for seedling stages, odor removal, or rapid heat dissipation – all via a dial on the 6.6ft waterproof power cord.
Wide Applications - Clean and freshen the air for your plants, maintaining a cool and balanced environment. Ideal for indoor ventilation and odor filtration, it is widely used in grow tents, hydroponics, bathrooms, greenhouses, basements, kitchens, resin covers, and engraving enclosures.
