Quest PowerDry 4000 Pro

The Quest PowerDry 4000 Pro is a larger capacity, stainless steel unit designed with the perfect combination of high performance and portability, with its manageable size and weight. The multiple ducting options on the Quest PowerDry 4000 Pro not only allows for ducting both the intake and processed air, but also makes it possible to easily combine this unit with a HEPA air scrubber, air conditioner or desiccant dehumidifier.

As an added benefit, the significant air filtration system of all Quest Dehumidifiers dramatically improves indoor air quality.


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 4000 Pro is 176 pints per day.
