Features

👍 [120 PPD COMMERCIAL CRAWLSPACE DEHUMIDIFIER] This commercial-grade unit removes up to 120 pints of water per day at saturation (55 pints per day per AHAM), effectively controlling humidity in spaces up to 1,300 sq.ft. Built with a durable metal outer casing, it withstands rugged commercial conditions and safeguards internal components for long-term reliability — a dependable choice for crawl spaces, basements, garages, and storage areas.

👍 [BUILT-IN POWERFUL CONDENSATE PUMP] Engineered to solve distance drainage challenges, this unit comes with a built-in condensate pump and an included drain hose that extends up to 19.6 feet. Whether your installation calls for gravity drainage or upward pumping, this crawlspace dehumidifier handles both with ease, making it a reliable solution for wet rooms and hard-to-drain spaces.

👍 [FULLY AUTOMATIC, EFFORTLESS OPERATION] This commercial-grade dehumidifier automatically restarts after a power outage, defrosts in low temperatures, and supports continuous drainage via a hose — no manual bucket emptying required. Complete humidity management for your home, basement, crawl space, or commercial space is easy and reliable, requiring little to no daily intervention, making it an industry favorite for demanding environments.

👍 [AUTO DEFROSTING SYSTEM] Our advanced auto-defrosting system continuously monitors ambient temperature using built-in sensors. When low temperatures are detected, the unit initiates an automatic defrost cycle to prevent frost buildup — the compressor pauses while the fan continues running, allowing the frost to thaw. Once complete, normal operation resumes, conserving energy and extending the lifespan of the unit.

👍 [6-YEAR LIMITED WARRANTY & ETL LISTED] This AlorAir crawl space dehumidifier is ETL listed for safety and backed by a 6-year limited warranty, including full coverage for the first two years — with professional customer support ready to help whenever you need it.
