The Patterson EC Variable-Speed Fan series features electronically commutated (EC) motors that provide adjustable airflow from 300 to 1,800 RPM. Available in three sizes, these fans deliver controlled air circulation for different cultivation stages, from gentle airflow over young plants to stronger circulation through dense canopies. The auto-adapting motor operates on single-phase power supplies from 115V to 277V.
