Schaefer Twister oscillating circulation fan
The Schaefer Twister uses proven geared oscillation to move 4,100 to 9,600 CFM across its 20, 24, and 30 inch sizes. Ninety degrees of oscillation and 45 degrees of head tilt aim air across the canopy at any stage. A 2-speed high-efficiency motor and 10 ft cord give flexible placement. OSHA-compliant guards keep the space safe.
Reliable airflow for greenhouses and hydroponic grow rooms
Steady side-to-side movement breaks up hot spots and dead zones across a dense canopy. Growers use it to strengthen stems, cut disease pressure, and support even transpiration. Two speeds dial in gentle air for young plants or stronger flow for mature crops. Schaefer geared oscillation gives smooth, consistent sweeps that reduce plant stress. Front and rear guards protect workers and plants in busy rooms. It mounts to a wall or pedestal for fixed or portable use. A 2-year warranty backs continuous use, and each fan is assembled in the USA.
