Schaefer Versa-Kool 20 in greenhouse circulation fan
The Schaefer Versa-Kool 20 in moves up to 5,470 CFM in a smooth HAF pattern to mix air from ceiling to floor. Deep tapered guards and matched blades keep the stream coherent while it runs quiet and efficient. A 1/3 HP motor spins three aluminum blades at up to 1,725 RPM. It ships with a mounting bracket and power cord.
Durable HAF fan for hydroponic and indoor grow spaces
Steady horizontal airflow breaks up hot spots and humid pockets where mold and mildew take hold. Growers rely on that even mixing to cut disease pressure and spread CO2 across a dense canopy. Powder-coated steel guards and a rugged motor stand up to humid, corrosive grow rooms. The included bracket gives several mounting angles for aisles or tight tents. Optional variable-speed controls and misting kits extend the climate control as plant loads grow. It runs at 115 or 230V for flexible wiring.
