Product Overview

Engineere & Assembled in the USAThe Quest 506 Overhead Dehumidifier is powerful and efficient for tough commercial and industrial spaces. Its 506 pint capacity makes it one of the most powerful, as well as efficient, commercial dehumidifiers on the market. 

Protect valuable assets and eliminate damaging moisture in greenhouses, indoor growing facilities, warehouses, military storage spaces, and other large areas.

Note: This is available as 230-volt model which uses a NEMA 6-20P plug, or 277-volt model with a NEMA L7-20P plug.

Versatile Uses and Installation 

Thanks to its unique design this American-engineered dehumidifier can be used in a wide variety of industrial and commercial spaces, and offers impressive MERV 13 filtration.

  • Operates in any temperature between 56 and 95 degrees F.
  • A gravity drain hose is included for removing the excess moisture it collects. You can either drain it outside or into a reservoir.
  • This overhead dehumidifier can be ducted when necessary; intake and exhaust duct kits may be purchased separately.

Note: A remote humidistat is required for use. The Quest DEH3000R controller is a popular choice for our customers. 

Maintain Optimal Humidity Levels

The Quest 506 Overhead dehumidifier provides effective moisture-removal and humidity control which can eliminate costly quality errors, prevent rust and corrosion, and maintain correct humidity levels for indoor growing spaces.

Overhead installation also saves floor space and helps mitigate moist air trapped near the ceiling.

Efficient Operation

The Quest 506 Overhead Dehumidifier removes an industry-leading 506 pints of moisture per day, yet it’s also one of the most efficient high capacity designs available. 

CA Title 24 ComplianQuest's patent-pending coil technology allows for higher efficiency in a smaller unit. It pulls only 11 amps and has a maximum efficiency of 8.1 pints/kWh. This makes it compliant with California Title 24 updated regulations for energy-efficiency for both overhead (portable) and ducted (whole-house) installation. No high-capacity dehumidifier on the market can remove 500 pints of moisture in such a small frame.

Using fewer amps means that less heat is generated by the unit--another bonus if you're using this model in growing spaces.

Additional Features

  • Long Power Cord: A 10-foot power cord makes it easy to install in just about any location.
  • Superior MERV 13 Filtration: Air exiting the dehumidifier is filtered with a MERV 13 filter, which catches particles like smoke, smog, bacteria, microscopic allergens and debris. Filter changes are suggested 6-8 weeks if the dehumidifier is being used in growing spaces. 
  • 5-Year Compressor Warranty: Its backed by a 5-year compressor and refrigerant system warranty and 1-year parts & labor warranty.  
  • Auto Restart: After power outages, this high capacity dehumidifier turns back on to its previous settings once power is restored.
  • Integrated Handle: Integrated heavy-duty handles make transporting easier. The threaded rod handles can attach to a 3/8-inch rod (not included) if you choose to use it as an overhead dehumidifier. Moving this 280-pound model will require at least two people. 
  • Low Voltage Control Option: Wire the remote dehumidistat using a low-voltage terminal block. 
  • Remote Humidistat Required: A remote humidistat is required for use. We recommend the Quest DEH3000R controller
