Key Features

• Powerful & Efficient Airflow
  Mixed-flow design and an energy-efficient EC motor drive high-quality impellers to deliver up to 205 CFM of airflow while using only 27W of power. Lightweight ABS blades reduce resistance and boost airflow by up to 40%.

• Ultra-Quiet Operation
  Engineered for stealth, this 4″ exhaust fan operates at just 26.8 dB, making it ideal for home grow tents and indoor setups where low noise is important.

• Smart RJ12 Connectivity (2025 Version)
  The latest 2025 model includes an RJ12 port, allowing you to connect to Spider Farmer GGS Controllers and Power Strip Kits for advanced automation and remote control via the Spider Farmer app.

  Through the app or controller, you can:

  • Choose between four operating modes

  • Set start and stop times

  • Adjust running and standby speeds

  • Control CO₂ devices On/Off

• Improved Temperature Control
  By efficiently exhausting hot air from grow lights and equipment, the fan helps maintain stable temperatures, preventing heat stress and supporting vigorous growth.

• Humidity Management
  Continuous air exchange helps reduce excess humidity, limiting the risk of mold, mildew, and pest problems that can damage plants.
