Heavy-Duty Greenhouse Fan for Humid Grow Environments
The Multifan 20" Greenhouse HAF Q Fan is engineered for continuous use in wet, high-humidity spaces, making it ideal for hydroponic greenhouses and sealed grow rooms. An IP55 rating, totally enclosed aluminum motor housing, and Class F insulation (tested to 140 °F) deliver dependable performance in harsh, washdown-ready environments while extending motor life.
Greenhouse Fan Designed for Efficient HAF Air Circulation
With a 20" polypropylene impeller and optimized venturi, this HAF greenhouse fan moves up to 5,100 CFM in a tight, controlled airflow pattern that improves air mixing without beating up your plants. The compact, white polypropylene housing minimizes shading over your canopy, while variable speed capability, easy-to-remove wire guards, and low-maintenance sealed bearings give hydroponic growers precise, energy-efficient climate control with less downtime.
Key features:
-
Uniform canopy climate: Horizontal Air Flow (HAF) pattern evens out temperature and humidity across the greenhouse, reducing hotspots and microclimates around dense hydroponic systems.
-
Handles extreme humidity & washdowns: IP55 rating, sealed bearings, and severe-duty TEAO motor are built for misting, wet floors, and frequent cleaning common in hydroponic grow spaces.
-
Energy-efficient high CFM: Up to 5,100 CFM from a 1/2 HP motor provides strong air movement with a considerable increase in energy efficiency over previous versions and compliance with upcoming ErP regulations.
-
Protects plants while boosting airflow: Aerodynamic inlet and focused airflow pattern move a lot of air without excessive leaf flutter or plant stress, ideal for delicate hydroponic crops.
-
Long service life in harsh environments: Lightweight polypropylene impeller reduces wear on motor components, while Class F insulation and auto-reset thermal protection guard against overheating in hot, enclosed greenhouses.
-
Flexible installation & control: Compact, stackable housing with aluminum motor suitable for suspension by profiles or chains, plus variable speed capability for dialing in airflow in serial or parallel HAF setups.
