Active Air Dehumidifier — 110 Pint Commercial-Grade Unit

Commercial Moisture Removal for High-Humidity Grow Rooms

Excess humidity in a grow room raises the risk of mold, mildew, and slowed transpiration, and a residential-grade dehumidifier often can't keep pace with the moisture load a dense planting produces. The Active Air 110 Pint Dehumidifier removes up to 110 pints of moisture per 24 hours at 86F/80% RH test conditions, built around a redesigned evaporator and a heavy-duty powder-coated casing sized for grow-room duty rather than a household basement.

It supports automatic restart, letting it resume operation after a power interruption or when paired with a humidity controller, instead of requiring a manual restart every time conditions trip it off and back on.

Key Features & Benefits

• 110 pint / 24hr removal rate — rated at 86F/80% RH, grow-room-representative test conditions.
• Redesigned evaporator — supports the unit's rated moisture-removal capacity.
• Automatic restart — resumes operation after a power interruption or humidity-controller trigger without manual intervention.
• Heavy-duty powder-coated casing — built for continuous grow-room duty rather than occasional household use.

Who Should Use This Dehumidifier

Commercial growers and larger grow rooms running humidity loads beyond what a residential dehumidifier can handle are the fit for this 110 pint commercial-grade unit.

Frequently Asked Questions

How much moisture does this unit remove?

It's rated to remove up to 110 pints of moisture per 24 hours at 86F/80% RH test conditions. Actual removal in your room depends on temperature, humidity, and airflow, since manufacturer ratings are measured under standardized conditions.

Does it work with a humidity controller?

Yes, it supports automatic restart, which is what lets it resume operation automatically when a connected humidity controller calls for dehumidification. That avoids the manual restarts a simpler unit would require after each cycle.

What happens if the power goes out?

The automatic restart feature also lets the unit resume operation on its own after a power interruption, rather than sitting off until someone manually restarts it. That matters in unattended commercial spaces.

How is this different from a residential dehumidifier?

This unit is built around a heavy-duty powder-coated casing and a redesigned evaporator sized for continuous, high-capacity grow-room duty, where a residential dehumidifier is designed for occasional household use at a lower moisture load. Its 110 pint rating is well above what most residential units are built to sustain.

How do I size this unit for my room?

Match the unit's 110 pint/24hr rating against your room's actual moisture load, which depends on plant density, temperature, and humidity target rather than square footage alone. Running an undersized unit continuously at full output usually means the room's humidity is above the unit's actual capacity.
