Spider Farmer 4" Inline Fan Kit | 205 CFM Grow Tent Fan

The Spider Farmer 4" Inline Fan Kit is a professional-grade, all-in-one ventilation and air filtration assembly designed to take total control of your growing climate. Ideal for hobbyists and space-conscious growers, this complete kit eliminates the frustration of buying unmatched ventilation pieces. By combining a high-pressure inline exhaust fan, an industrial-tier activated carbon filter, and flexible ducting, it guarantees continuous fresh air circulation while completely neutralizing pungent grow room odours.

At the core of the extraction unit is a next-generation brushless EC motor paired with custom oblique mixed-flow blades. This internal architecture reduces airflow resistance by 40%, allowing the fan to pull a massive 205 CFM of air while drawing a mere 27 watts of power. Operating at a whisper-quiet 26.8 dB, it delivers heavy-duty ventilation with 50% less acoustic noise than traditional AC blower fans. The heavy-duty housing is fully dustproof and waterproof, ensuring absolute electrical safety in humid environments.

The kit includes a professional 4-Inch Air Carbon Filter constructed with a heavy-duty metal housing and premium RC412 Australian activated charcoal. Featuring an extra-thick 38mm carbon bed and a surface area rating of 1200+ IAV, the filter traps and chemically neutralizes organic compounds, mold spores, and pollen. It comes equipped with a machine-washable cloth pre-filter designed to catch large dust particles, preventing premature clogging and extending the lifespan of the core activated carbon layer.

The 2025 edition features an integrated RJ12 data port interface, making it fully compatible with the advanced Spider Farmer GGS Smart Ecosystem. Using the dynamic 10-speed manual controller included in the box, or by linking it directly to a GGS environment hub, growers can unlock automated climate programming. This allows you to scale extraction speeds dynamically based on real-time temperature and humidity spikes, set minimum standby cycles, or manage your environment via the Spider Farmer App.
