Quest PowerDry 850D Pro

The Quest PowerDry 850D Pro Desiccant provides the perfect blend of portability, versatility, and performance in a medium-capacity desiccant dehumidifier. It combines the wide operating range and ultra-low grains of the Quest PowerDry 1200D Pro with the portability of a refrigerant dehumidifier like our Quest PowerDry 4000 Pro. The included remote humidistat and process blower speed control allow you to tailor the drying to the task at hand. The 850D operates both vertically or horizontally and is perfect for low clearance applications, fitting inside most crawlspaces. The lower carrying handle makes moving the unit down stairs, as well as into and out of a crawlspace, a breeze.

The PowerDry 850D delivers 850 CFM of ultra-low grain process air and removes a stunning 370 pints per day at AHAM conditions. The true four-hole design* allows for positive, neutral, or negative pressurization of the affected area.

Power to the unit is provided by either a 30- or 50- amp, 230-volt grounded power cord (both are included). The reactivation air stream is ducted through 6” flex duct, which is also provided with the unit.

*Having completely separate process and regeneration airstreams.

370 pints per day

Standard conditions are determined by the American Home Appliance Manufacturers (AHAM) and are used because capacity will vary with conditions. AHAM standard rating conditions are 80ºF and 60%RH. At these conditions, the capacity of the Quest PowerDry 850D Pro is 370 pints per day.
