Quest 335 277V High Efficiency Overhead Dehumidifier – 345 Pints/Day

Get to Know the Quest 335 High Efficiency Overhead Dehumidifier with M-CoRR Technology – 345 Pints/Day

The Quest 335 Grow Dehumidifier delivers powerful moisture removal, advanced energy efficiency, and superior air filtration, all in a high-voltage, low-amperage design built for commercial grow rooms and industrial-scale cultivation facilities.

This model perfectly fits grow operations with existing 277V or 208/230V electrical infrastructure, often installed for lighting systems. With lower amperage draw, it frees up power for other critical equipment while still delivering 345 pints per day of water removal at 80°F and 60% RH. Built with Quest’s patented M-CoRR Technology, the Quest 335 recycles excess heat, reducing strain on your HVAC system and cutting operational costs.
