Excess humidity is one of the fastest ways to lose a crop. The Ideal-Air 120 Pint Dehumidifier with Internal Condensate Pump gives serious growers the muscle to pull moisture out of the air at scale — up to 120 pints per day — while keeping maintenance simple and drainage completely flexible. Whether you're running a sealed grow room, a commercial greenhouse, or a large indoor facility, this unit is built to keep your environment dialed in, day after day.
Why Ideal-Air Dehumidifier 120 Pint with Internal Condensate Pump
Ideal-Air has engineered this dehumidifier specifically for the demands of controlled-environment agriculture. Unlike consumer-grade units that struggle under continuous operation, this model is rated at 120 pints per day at 86°F/80% RH — real-world conditions that match what growers actually face. The built-in internal condensate pump eliminates the need for gravity drainage, giving you the freedom to place the unit wherever it's most effective, not just where a floor drain happens to be.
The low-temperature defrost function keeps the unit running efficiently even when ambient temps drop, and the washable, removable filter means you spend less time on maintenance and more time on your grow. This is a workhorse designed for growers who can't afford downtime.
Key Benefits
- High-Capacity Moisture Removal – Pulls up to 120 pints of water per day at 86°F/80% RH, keeping humidity in check even in large, sealed environments.
- Internal Condensate Pump – Pumps collected water out without relying on gravity, giving you flexible placement options anywhere in your facility.
- Permanent Drainage Option – Can be plumbed directly for continuous, hands-free drainage — ideal for commercial or unattended operation.
- Low-Temperature Defrost – Automatically defrosts coils in cooler conditions so performance stays consistent year-round.
- Easy Filter Maintenance – Removable, washable filter keeps airflow clean and reduces service time between maintenance cycles.
- Automatic Shutoff – Removable 10-liter (21-pint) reservoir triggers an automatic shutoff when full, preventing overflow and protecting your floor.
- LED Display Panel – Clear, easy-to-read display lets you monitor and adjust settings at a glance.
- Built for Mobility – Integrated handles and wheels make repositioning the unit quick and effortless, even at 65 lbs.
- Efficient Airflow – 271 CFM air movement at 680W/7 Amps ensures thorough air circulation throughout the space.
Use Cases
- Sealed Grow Rooms – Maintain precise VPD targets in fully sealed environments where humidity can spike rapidly during lights-on periods.
- Commercial Greenhouses – Handle the high transpiration loads of large plant canopies without constant manual intervention.
- Propagation Chambers – Dial in humidity during cloning and early veg stages, then reduce moisture as plants mature.
- Drying and Curing Rooms – Control moisture levels precisely during post-harvest drying to protect quality and prevent mold.
- Multi-Tent Facilities – Use as a central dehumidifier for facilities running multiple tents or rooms off a shared HVAC loop.
- Year-Round Indoor Operations – Low-temp defrost capability makes this unit reliable through winter months when ambient temps drop.
Directions for Use
- Position the unit in the grow space with adequate clearance on all sides for airflow (minimum 12 inches recommended).
- For tank operation: insert the reservoir and set your target humidity on the LED panel. The unit will shut off automatically when the tank is full.
- For continuous drainage: connect a drain hose to the condensate pump outlet and route to a floor drain or collection point.
- For permanent plumbing: connect directly to a drain line using the gravity drain port for fully hands-free operation.
- Clean the washable filter every 2–4 weeks depending on dust load in your environment.
- Allow the unit to run for 24–48 hours after initial setup to stabilize humidity levels in the space.
What Growers Are Saying
"This unit has been running non-stop in my 20x20 sealed room for six months without a single issue. Humidity stays locked in and the pump drainage is a game changer."
— Marcus T., Commercial Grower
"Easy to set up and the LED panel makes it simple to dial in exactly where I need humidity. Highly recommend for any serious indoor operation."
— Sarah P., Greenhouse Grower
"I was skeptical about the internal pump but it works perfectly. No more worrying about where to put the unit — I just run the hose wherever I need it."
— Daniel R., Home Grower
Frequently Asked Questions
What does "120 pints per day" actually mean for my grow room?
It means the unit can remove up to 120 pints (about 15 gallons) of water from the air per day under standard test conditions (86°F/80% RH). In cooler or drier conditions, actual removal rates will be lower — size your dehumidifier based on your room's peak humidity load.
Do I need a floor drain to use this unit?
No. The internal condensate pump allows you to route collected water upward or horizontally to any drain or collection container, eliminating the need for a floor drain directly beneath the unit.
Can I leave this running unattended?
Yes. When plumbed for continuous drainage, the unit runs indefinitely without manual intervention. In tank mode, the automatic shutoff prevents overflow if the reservoir fills.
Is this unit compatible with environmental controllers?
The Ideal-Air 120 Pint Dehumidifier can be plugged into most 115V environmental controllers that use an outlet-based on/off signal. Check your controller's amperage rating — this unit draws 7 amps at full load.
How often does the filter need to be cleaned?
In most grow environments, cleaning the washable filter every 2–4 weeks is sufficient. Higher-dust environments may require more frequent cleaning to maintain optimal airflow and efficiency.
What is the warranty on this unit?
Warranty terms vary by retailer and region. Contact Grow It Depot for current warranty information and support options for the Ideal-Air line.
