The Quest 335 277V Overhead Dehumidifier delivers powerful humidity control with advanced features tailored for commercial and industrial facilities utilizing 277V outlets. Removing up to 345 pints of water per day at 80 degreesF and 60% relative humidity, this unit operates with industry-leading efficiency, thanks to patented M-CoRR™ Technology, which recycles excess heat to reduce energy consumption and minimize heat output. Its MERV 13 filtration system captures dust, mold spores, allergens, and bacteria, providing superior air quality and a healthier environment. Filter compensation technology maintains consistent airflow, even as filters become clogged. With plug-and-play functionality, a digital control interface, and optional external control compatibility, the Quest 335 277V is simple to integrate into any space. Additional features include a low amp draw, auto-restart capability, and a long power cord for flexibility. Assembled in Madison, Wisconsin, and backed by a 5-year warranty, this dehumidifier is a reliable and efficient solution for heavy-duty moisture management.
