Greenhouse circulation fan for even climate control
The Schaefer Versa-Kool 20 in greenhouse circulation fan is built to move serious air—up to 5,470 CFM—while staying whisper-quiet and energy efficient. Deep, tapered guards and precision-matched motors and blades create a smooth, coherent HAF airflow pattern that gently mixes air from ceiling to floor, helping prevent hot spots, humidity pockets, and plant stress. As one of the most dependable fans for greenhouses, it’s ideal for reducing disease pressure, improving CO₂ distribution, and maintaining a consistent environment in hydroponic setups.
Durable HAF fan for hydroponic & indoor grow spaces
With powder-coated steel guards, included mounting bracket, and power cord, this fan installs quickly and stands up to the demanding conditions of indoor gardens and commercial grows. It’s a smart choice if you’re looking for the best fan for greenhouse aisles or tight grow spaces where quiet, reliable airflow matters more than noise and bulk. Compatible accessories like variable speed controls and optional misting kits make it a versatile ventilation fan for greenhouses and grow rooms that need customizable cooling and air movement.
Key features:
-
Reduces plant heat stress by delivering up to 5,470 CFM of airflow, helping pull heat away from lights, trays, and root zones.
-
Improves humidity and disease control through HAF “racetrack” circulation that breaks up stagnant, humid pockets where mold and mildew thrive.
-
Enhances CO₂ and nutrient uptake by keeping fresh, conditioned air moving uniformly across leaf surfaces in dense hydroponic canopies.
-
Built for harsh grow environments with powder-coated steel guards and a rugged motor designed for long runtimes in humid, corrosive conditions.
-
Easy installation in grow rooms and greenhouses thanks to the included mounting bracket and power cord, plus multiple mounting options for flexible placement.
-
Expandable climate control with optional variable speed controllers and misting kits, letting you fine-tune airflow and cooling as plant loads increase.
