Quest 506 Commercial Dehumidifier

The Quest 506 is the industry’s first 500-pint, 230 V single-phase commercial dehumidifier, purpose-built for commercial-scale growing operations. As with all Quest products, the 506 can be operated from the ground or conveniently mounted overhead to save space.

It is the most energy-efficient, high-capacity dehumidifier on the market—drawing only 11 Amps while delivering an impressive 8.1 pints/kWh. Built in the USA, this unit is engineered for durability, performance, and maximum efficiency.

The system comes equipped with standard MERV-11 filtration, capable of capturing particles, including mold spores, as small as 1 micron. For added flexibility, optional condensate pump and ducting kits are available to accommodate specialized applications or space-restricted environments.

Note: A separate humidistat is required. We recommend the DEH 3000R Wall Mounted Unit for optimal performance.
