  • Product Overview

    Durable, portable, and built to stand up in even the toughest environments, the Dri-Eaz LGR 3500i Dehumidifier fights damaging humidity quickly and effectively with high efficiency operation. Part of the Dri-Eaz intelligent LGR-i series models, the 3500i is designed for water damage restoration, structural drying, construction, and other jobs that require temporary industrial-strength dehumidification. This workhorse extracts 170 pints of damaging moisture per day under AHAM conditions (80 degrees F, 60% relative humidity) using just 10.5 amps of power. Trust it to quickly dry carpeting, carpet pads, floors, walls, and other water-damaged areas.

    Extreme Water Removal

    The Dri-Eaz 3500i LGR Dehumidifier is a low-grain refrigerant dehumidifier that continues removing moisture even in dry, low-temperature environments. This is because LGR dehumidifiers have better heat exchange and defrost abilities over traditional refrigerant dehumidifiers, making them reliable solutions for restoration tasks. The 3500i removes up to 240 pints per day maximum in a saturated space (90 degrees F, 90% relative humidity), in addition to its AHAM-tested removal efficiency of 170 pints per day.

    For low-hassle emptying, this system’s high-power condensate pump continuously pumps collected moisture out of the dehumidifier. Simply route the included 40-foot drain hose to the quick connect port and route it to a nearby drain, bucket, sink, or the outdoors. Condensate can also be pumped vertically up to 20 feet if necessary.

    Intelligent Operation

    Like its sister model, the Dri-Eaz 2800i, the Dri-Eaz 3500i Dehumidifier is an “intelligent” LGR unit that features a self-monitoring system to maximize performance in all environmental conditions. Onboard wireless sensors automatically monitor and display inlet and outlet conditions on the digital control panel. You can view these readings at a glance and use them to better manage dehumidifier operation and jobsite progress. The LGR 3500i is also compatible with the Dri-Eaz HygroTrac Remote Monitoring System. This system allows you to monitor job conditions and equipment performance in real-time via the Internet at any time and from any place.

    Additional Features

    • Automatic Humidistat – A built-in humidistat adjusts operation to automatically maintain your desired humidity level in all conditions.
    • Auto Defrost – In very cold temperatures, the dehumidifier automatically warms frost build-up on the coil and transforms it into condensation.
    • Digital Control Panel – The Dri-Eaz LGR 3500i control panel boasts a digital display and touchpad with 4 different keys, displaying English system messages, no confusing codes.
    • High Airflow Filter –A vacuum-able 3M High Airflow Air Filter protects internal components from damage due to dust and other particles, ensures efficient operation, and catches allergens.
    • Pump Purge Switch – With this switch, you can easily purge collected water in preparation for transport.
    • Hour Meter – Tracks job hours and total life hours for task management.
    • Rotomolded Housing – The 3500i is constructed with Dri-Eaz's legendary rotomolded polyethylene housing, which resists dents and scratches.
    • Semi-Pneumatic Tires – These tires are puncture-proof, lightweight, and rugged for easy transport and a long service life.
    • Integrated Handle – Along with semi-pneumatic tires, the sturdy handle makes transport from job to job a breeze.
    • Detachable Power Cord – The cord measures 25 feet for usage flexibility.


    Designed for a variety of restoration jobs, the Dri-Eaz LGR 3500i Restoration Dehumidifier performs super-efficient, high-capacity moisture removal while intelligent features help tailor operation in any space.

    What Customers Love

    • Intelligent Monitoring – A self-monitoring performance system with continuous reporting of inlet and outlet conditions help you maximize dehumidification in specific environments.

    Things to Consider

    • Accessories to Speed Drying – Consider adding the Dri-Eaz VMax Adapter to better target warm dry air across the drying space or the Dri-Eaz Ace TurboDryer to help circulate dehumidified air widely for faster drying.
