A Heavy Duty, High-Efficiency Dehumidifier

Control Humidity in Your Grow Rooms, Greenhouses, and Other Facilities

The Quest 335 277V dehumidifier offers the same quality and features as our original Quest 335 208/230V units but with 277V voltage for use in industrial facilities. The 277V unit is an excellent fit for grow rooms, many of which traditionally have 277V outlets already installed for lighting. As an added benefit, these higher voltage units use less amperage, freeing up electricity for other equipment in the grow room.

Advanced Dehumidifier Technology

Both Quest 335 units (208/230V and 277V) boast our unique patented M-CoRR technology. This multi-coil refrigeration design recycles excess heat to provide the highest efficiencies available on the market while reducing heat (BTUs) output into your space.

Improved air quality with Quest’s Merv-13 + filter compensation technology

In addition to industry-leading MERV-13 filtration, the 335 features Quest’s filter compensation technology. Filter compensation technology increases fan speed as the filter becomes increasingly clogged with pollen, powdery mildew, and dirt. This speed adjustment allows the same amount of air to pass through the filter without reducing the cubic feet per minute (CFM). As a result, the Quest 335 can work consistently to optimize your environment with maximum energy efficiency and consistency.

Made in the USA

The Quest 335 277V dehumidifier is engineered and assembled in Madison, Wisconsin, and is backed by a 5-year warranty. In addition, this unit meets California Title 24 requirements for both ducted (whole-home) and non-ducted (portable) installations.

Vapor Pressure Deficit and Why it Matters

The gardening world is filled with trends and phrases that come and go as quickly as they’re created. Sometimes these concepts are thrown around without full understanding, especially with the more scientific processes. One of the most misunderstood concepts is vapor pressure deficit, or VPD, as it’s commonly called.
