The Spider Farmer 4 Inch Inline Fan (205CFM) is a high-performance ventilation solution designed to maintain ideal growing conditions in your indoor garden. Engineered with a mixed-flow EC motor, this fan delivers efficient airflow up to 205 CFM while consuming only 27 watts—ensuring energy savings without compromising performance. The lightweight ABS blades reduce airflow resistance by up to 40%, maximizing efficiency and prolonging the lifespan of your ventilation system.

This kit includes a carbon filter and ducting system to eliminate excess moisture, heat, and odors—critical for maintaining a healthy grow space. The fan’s exhaust function removes stale air, while the CO₂ device integration (requires a SensorPro set) ensures seamless compatibility with intake/exhaust systems.
Whether you’re running a small grow tent or a large indoor garden, this fan ensures consistent temperature and humidity levels, preventing mold, heat stress, and poor yields. Pair it with our Spider Farmer LED grow lights and ventilation systems for a complete climate-controlled grow environment.
