F5 Greenhouse Circulation Fans – 8", 12", 20", 24"

Powerful, Quiet, and Built to Last
F5 Circulation Fans are designed for superior air movement, helping to reduce heat stress, control humidity, and improve air quality in greenhouses, barns, warehouses, and grow spaces. Engineered for consistent cooling, these fans generate a smooth “racetrack” circulation pattern (Horizontal Air Flow, HAF) that moves air evenly from ceiling to floor—creating healthier environments for plants, animals, and people.


Key Features

  • Efficient Airflow: Deep-guard design ensures maximum circulation with minimal noise.

  • Durable Construction: Powder-coated steel guards resist corrosion; hot-dip galvanized options for added rust protection.

  • Flexible Mounting: Includes powder-coated ceiling bracket and power cord. Multiple mounting options available.

  • Built for Longevity: Precision-matched motors and blades for optimal efficiency.

  • Versatile Use: Compatible with variable speed controls; optional misting kits available for added cooling.

  • Ready to Use: Comes with 5 ft power cord and mounting hardware.
