Greenhouse Fans
Hydrofarm introduces
Schaefer high-velocity
greenhouse fans. These
uniquely designed
horizontal air flow fans
circulate air in a coherent
horizontal pattern, creating
a gentle “racetrack” air
flow. This helps maximize
heat distribution and
humidity control by mixing
the air from ceiling to floor.
Schaefer fans are built
to last, with corrosion-
resistant, powder-coated
steel guards and mounting
brackets, ultra-quiet
operation, and multiple
mounting options. Proudly
made in the USA, Versa-
Kool circulation fans utilize
a deep guard design and
matched high-quality
motors and blades.
