Airrex ADH-8000R Portable Dehumidifier 25.4 Gallon/Day R-32 Refrigerant 554 CFM Built-In Drain Pump 115V Digital Controls
Airrex ADH-8000R Portable Dehumidifier — 25.4 Gal/Day, R-32
The Airrex ADH-8000R is a fully portable, high-capacity dehumidifier engineered for rapid drying and precise humidity control. Built for restoration companies, building drying, and industrial process drying, it pulls up to 25.4 gallons of moisture per day at 554 CFM airflow, with a built-in replaceable drain pump for continuous water removal. The "R" series uses modern R-32 refrigerant, a digital control panel with 24-hour timer, and an automatic hot gas bypass defrost system that keeps it running smoothly in cool conditions. A stainless-steel frame and heavy-duty 12-inch casters make it easy to roll between job sites without losing stability.
Key Features
Engineered for dependable performance with the features that matter most.
High-Capacity Moisture Removal
Removes up to 25.4 gallons per day (15.9 gal/day nominal) — built to dry water-damaged buildings, large spaces, and ongoing process-drying jobs fast.
Eco-Friendly R-32 Refrigerant
The ADH-8000R is the new generation of this unit, using modern low-GWP R-32 refrigerant for efficient dehumidification with reduced environmental impact.
Automatic Hot Gas Bypass Defrost
Prevents frost buildup on the coils, so the unit keeps dehumidifying even in cooler ambient conditions without interrupting the drying cycle.
Digital Control Panel
Current and set humidity display, adjustable 2-step fan speed, 24-hour off timer, error messaging, and a forced drainage button for clean unit relocations.
Built-In Replaceable Drain Pump
A powerful automatic drain pump removes condensate continuously — no manual tank emptying, no interruptions to the drying job.
12" Heavy-Duty Casters
Stainless-steel frame, ergonomic handle, and 12-inch industrial casters let one operator move the 118 lb unit across rough job-site terrain with ease.
Note: The ADH-8000R draws 10.25 A on a standard 115V circuit; check that the outlet and any extension cords are rated for the load. Before relocating, use the forced-drainage button to flush condensate and prevent spills in transit.
Ideal Applications
From flood restoration to industrial process drying, the ADH-8000R handles humidity control jobs that smaller residential dehumidifiers can't touch.

Frequently Asked Questions
What's the difference between the ADH-8000 and ADH-8000R?
The "R" suffix indicates the newer generation of this unit. The ADH-8000R uses modern, low-GWP R-32 refrigerant in place of the older ADH-8000's R-410A, while keeping the same proven design and capacity ratings.
How much moisture does the ADH-8000R remove per day?
The ADH-8000R removes up to 25.4 gallons per day at max conditions and approximately 15.9 gal/day at nominal conditions. Actual moisture removal depends on ambient temperature and humidity.
Does the ADH-8000R need to be plugged into a special outlet?
No. It runs on standard 115V single-phase, 60 Hz power and draws 10.25 A, so it plugs into any standard outlet rated for the load.
Does the ADH-8000R have a built-in pump?
Yes. It includes a powerful built-in replaceable drain pump that automatically removes collected water, so the unit can run continuously without manual tank emptying.
What does the hot gas bypass do?
The automatic hot gas bypass defrost prevents frost from building up on the coils when running in cooler conditions. This keeps the unit dehumidifying efficiently rather than shutting down for defrost cycles, and extends compressor life.
What temperature range can the ADH-8000R operate in?
It operates between 33°F and 100°F, making it suitable for cold-room drying, restoration jobs in unheated spaces, and warm process-drying applications.
