Info & Guides

Description

Engineered & Assembled in the USAMaintain optimal relative humidity levels throughout your greenhouse or indoor gardening space with the Quest Dual 110 Overhead Dehumidifier. This small, compact unit is affordable and removes up to 110 pints of water under standard operating (AHAM) conditions (80 degrees F, 60 percent RH) while the onboard dehumidistat carefully monitors indoor humidity conditions.

This compact dehumidifier is a great addition to self-storage spaces, smaller warehouses, and other commercial humidity control applications.

Humidity + Moisture Control and Monitoring

Growing and managing your business is your utmost concern, and with the Quest 110, you can take a “hands-off” approach to humidity control using the onboard dehumidistat. Designed to consistently monitor indoor humidity, you can set it to maintain one of these 3 options:

  • Drier (20 to 30 percent humidity)
  • Normal (45 to 55 percent humidity) - Recommended
  • Humid (80 to 90 percent humidity)

Gravity Drain Options

The Quest 110 dehumidifier can be set up with one of several gravity-drain traps for efficient removal of condensate as it is collected.

  • Standard Loop
  • Pretzel Loop
  • Floor Bend
  • PVC Trap – Recommended for ceiling installation

Ceiling or Floor Installation Options

The Quest Dual 110 can accommodate a variety of space requirements or restrictions. If floor space is in short supply, it can be easily suspended from the ceiling. This also makes reducing humidity near the ceiling much simpler. Use two Quest mounting brackets and chains to properly install.

The Dual 110 can also be installed on the floor or ground, providing growers easy access to the onboard dehumidistat and other controls.

Note: The Quest Dual 110 Overhead Dehumidifier uses a NEMA 5-15P plug type. This is a 115-volt/4.9-amp, 3-prong plug with a face that looks like this:NEMA 5-15P Plug Face

Additional Features

  • Dual Air Distribution: Features the Quest Dual Air Distribution for optimal air circulation throughout spaces.
  • Premium Airflow: Pushes 365 CFM of dry air throughout smaller greenhouses and indoor gardens.
  • Temperature Range: Operates in temperatures ranging from 56 to 95 degrees Fahrenheit.
  • Fan Switch: Features two fan switch options; Fan On, which runs continuously, and Fan Auto, which operates only while dehumidifying
  • Low Amp Usage: Environmentally-friendly and good on energy, this unit only uses 7.1 amps.
  • MERV-8 Filter: Carefully remove particles from your indoor air with the MERV-8 filter.

Sylvane's Expert Take

Remove unwanted moisture and maintain optimal humidity levels for indoor grow rooms with the Quest Dual 110 Overhead Dehumidifier, featuring 365 CFM airflow, onboard dehumidistat, low amp usage, dual air distribution, and more.

What Customers Love

  • Small size, same power: Despite the smaller size, the Quest 110 is still a workhorse for smaller indoor growing areas, general storage spaces, and facilities where moisture build-up can be a problem.

    I've herd quest will last a long time.

    Easy install. Easy to use. It is efficient for my 120sq/ft room. It might be oversized for that room but it was on a good sale.

    I would recomend both the Quest Dual 110 and the Quest 70.

    I use the Quest Dual 110 in my basement grow room storage area. I also purchased a Quest 70 that I use in a second basement area. Both dehumidifiers are excellent at what they do and I would recommend them to anyone looking for a reliable unit. The Quest Dual 110 is a larger unit and will dehumidify an area with ease. The only strike against it is its loud. You would not want to use it in an area where the loud fan noise might bother you. The Quest 70 works just as well but is half the size and much much quieter. Perfect for home use where fan noise might be an issue.

    Quality dehumidifier

    Question is outstanding quality. The only issue is have is that this commercial dehumidifier doesn't have 24v controls. Price was by far the best I could find and I shipped thoroughly
