The Quest 335 277V Dehumidifier is designed for industrial facilities and grow rooms, offering the same quality and features as the original 208/230V units but with 277V voltage compatibility. Perfect for grow rooms with existing 277V outlets, these units use less amperage, freeing up electricity for other equipment. Featuring Quest's patented M-CoRR™ technology, both the 208/230V and 277V units recycle excess heat for maximum efficiency.
