The Quest PowerDry 4000 is the solution for growers wanting the flexibility and convenience of a large capacity portable dehumidifier. With over 22 gallons (176 pints) of capacity, the Quest PowerDry 4000 is ready for the toughest challenge.

Whether you are a grower looking for a dehumidifier with serious capacity for the most critical peaks of the grow cycle, a large supplemental dryer, or the flexibility of a product that can be moved to various rooms when needed, the Quest PowerDry 4000 is the product for you.

The PowerDry 4000 Pro also comes equipped with a solid-state control panel that is easy to read and operate. Another unique and innovative feature of the PowerDry 4000 Pro is the on board humidistat, which is located on the control panel. This feature gives the grower the ability to set the unit at a particular humidity level (between 20-70%RH) and the PowerDry will maintain that level throughout the growing process. When a specific humidity level is critical the PowerDry 4000 Pro is the perfect choice.

The Quest PowerDry 4000 is the flagship dehumidifiers in the Quest line of portable products, is constructed of the highest quality components, and is protected by a heavy duty Stainless Steel shell. Compared to other products, made of cheap plastic, the Quest PowerDry 4000 is simply the best product available, is built in the USA, and is designed to last for many years to come. No other portable dehumidifier comes close to the performance or quality of the Quest PowerDry 4000. Included with every Quest PowerDry 4000 is a high capacity filter. High capacity filtration is designed to capture mold, spores, pollen, and dust effectively cleansing the room of dangerous particles. When it comes to keeping your plants safe from mold, mildew, bacteria, and disease, accept no substitute.
