The ALORAIR 180 PPD Commercial Dehumidifier packs commercial capacity, 85 PPD under AHAM conditions and up to 180 pints at saturation, into a body low enough for crawl spaces. For more models, see our Whole-House & Crawl Space Dehumidifiers page.
Our Verdict
For flood repair, large crawl spaces and tight basements, this is our top 180-pint pick because it fits where tall LGR units cannot.
It is heavy at 64 pounds and louder than residential units.

Design
At 22.8 x 13.7 x 17.3 inches with two top handles, it slides into crawl spaces and tight basements.
The built-in pump uses a 19.6 ft hose and lifts water about 14.7 ft.
Controls
Airflow is 210 CFM for spaces up to 2,300 sq ft.
It is backed by ALORAIR’s 6-year limited warranty.
Placement Tips
In a crawl space, set the unit level on a vapor barrier, blocks or a hanger kit, away from standing water, with clear space around the intake and outlet. Run the drain hose with a steady downhill slope, or route the pump line to a sink, sump or exterior opening.
Seal vents and lay a vapor barrier first. A dehumidifier in a vented crawl space spends its effort drying outdoor air.
Running Costs and Care
Check the filter every month or two during heavy use and rinse or replace it when dirty. Make sure the drain line stays clear and, on pump models, test the pump occasionally.
Set the humidity target around 50% to 55%. The compressor then cycles off once the space is dry, which keeps running costs down.
How It Compares
Against the MOUNTO 180 Pint LGR, the ALORAIR is lower and lighter, while the MOUNTO has better readouts.
Against the ALORAIR HDi90, the 180 PPD has similar AHAM capacity in a more job-site oriented design.
