Designed for contractors, facility managers, and water damage restoration professionals, this high-efficiency portable dehumidifier easily tackles large damp basements, restoration sites, and commercial workspaces.

Fast-moving professionals will appreciate the Hi-E Dry 140’s unique design that allows it to double as a dolly for other water damage restoration equipment, like the Quest F10 High-Efficiency Air Mover.

Key Features and Benefits of the Quest Hi-E Dry 140 Dehumidifier

  • Water Removal: Rapidly removes up to 135 pints of moisture from the air under AHAM conditions (80 degrees F and 60 percent RH).
  • Industry-Leading Efficiency: Quest’s patented multi-coil (M-CoRR) technology delivers 7.2 pints per kilowatt-hour, so you get powerful drying with one of the lowest energy draws in its class.
  • Built-In Condensate Pump: A factory-installed pump and detachable hose lifts condensate up to 20 feet away, giving you flexibility on device placement when floor drains are out of reach. The pump can be quickly purged through the onboard controller. 
  • Wide Operating Range: This model performs reliably from 56 to 95 degrees F, making it suitable for cool basements, warm warehouses, and everything in between.
  • Simple Digital Controls: Set humidity levels, view real-time conditions, and more with the simple onboard controls.
  • Compact and Portable: Its integrated carry handles, low-profile recessed wheels, and a collapsible, nesting design make the Hi-E Dry 140 easy to transport and store.
  • Air Filter: The 12 x 14 x 1-inch MERV-10 air filter captures dust and debris before they reach internal components, maintaining airflow and reducing maintenance downtime.
  • Durable, Safe Design: The UL-rated and ETL-listed components and corrosion-resistant housing provide peace of mind on long-term projects.

Engineered for Demanding Spaces

Quest’s Hi-E Dry 140 is a powerful and thoughtfully engineered dehumidifier for the unpredictable environments that water damage restoration professionals face daily.

Thanks to its 3/8-inch push-to-connect drain port, swapping hoses in the field is quick and tool-free. Whether you’re mitigating water damage after a storm or maintaining optimal conditions in a woodworking shop, this dehumidifier adapts effortlessly, saving you time and labor on every deployment.
