Quest 335 High-Efficiency Dehumidifier
Description
Description
The Quest 335 High-Efficiency Dehumidifier is designed for commercial cannabis growers and other moisture-producing crops to control high humidity levels in grow rooms and greenhouses. Newly redesigned for greater performance and accessibility, this efficient dehumidifier can take on heavy workloads from larger grow houses. See Sylvane's review of the Quest 335 High-Efficiency Dehumidifier.
This versatile, high-efficiency unit also applies to storage areas, theaters, retail spaces, multi-family homes, schools, and restaurants.
A MERV-13 filter is included for capturing pollen, powdery mildew, and dirt. This ductable dehumidifier can be installed overhead or on the ground, featuring a digital control interface with an external control option. Proudly made in the USA.
Note: This is available as a 208/230 V model with a NEMA 6-15P plug, or 277 V model with a NEMA L7-15P plug.
Filter Compensation for Consistent Humidity
The Quest 335 features unique Filter Compensation Technology at its core, with a pressure switch connected to a variable-speed fan. When a change in pressure is detected, the fan slowly ramps up speed to maintain the desired CFM airflow, resulting in a consistent humidity level for better indoor growing results.
This technology allows the same amount of air to flow through the filter as it becomes dirty so that no CFM is lost and humidity is more effectively controlled. Set the fan button to Auto to activate filter compensation.
On-Board or External Control
Equipped with an onboard humidistat, the Quest 335 dehumidifier can be controlled manually by programming the desired set point and selecting high, low, or auto fan speeds. Only when the auto mode is selected is the filter compensation technology activated, and the fan speed automatically adjusts to pressure changes.
Connect the 335 to an external control using its low-voltage terminal block, and you can set and adjust the desired relative humidity level remotely. You can also daisy-chain up to three dehumidifiers on a single external control.
Redesigned for Efficiency and Performance
The Quest 335 High-Efficiency Dehumidifier has been redesigned with the R-454B refrigerant, which offers greater operating efficiency over previous models. This model provides considerable efficiency, drawing 8.5 pints of moisture from the air per kWH (at AHAM conditions) or 6 pints per kWH at 75 degrees F and 50 percent RH.
Easy to Duct
If your indoor growing space doesn't allow for the Quest 335's inside placement, it can be ducted into the grow house or room. The Quest 335 supply and return duct kit, which can be purchased separately, includes everything required for ducting.
Additional Features
- Drainage: The 3/4-inch threaded NPT port allows for gravity draining. If users require a lift, they can install an optional Quest condensate pump kit accessory.
- Indicator Lights: The indicator lights will illuminate for filter replacement and reset while the automatic defrost runs.
- Dark Mode: In dark mode, the lights on this model will remain on for 20 seconds before going dark. This is useful for continued operation during periods of darkness for plants.
- Integrated Handles: The integrated handles allow users to easily transport and place the dehumidifier.
- Installation Options: The Quest 335 can be hung overhead or installed on the ground.
- Long Power Cord: This model has a 10-foot power cord with a 14gaNEMA 6-15P plug face for 208-240V or NEMA L7-15P for 277 V.

- CGCanna g. d.ReviewingQuest 335 High-Efficiency DehumidifierI recommend this productRated 5 out of 5 stars3 years agoGreat product--operating as described & better than expected
This unit is incredible! Simply pulling water out of the air—have no doubt it will keep my plants from molding in flower. My humidity level is down now to under 50%. Seems to be running at a consistent rate—interested to see how this functions over time.
