Quest Dual 215 is the industry’s first 230 volt commercial dehumidifier. Like all Quest products it can be placed at ground level for plug and play operation or hung overhead out of the way. The Dual 215 is one of the most energy efficient dehumidifiers on the planet performing using minimal amps (6.9) and maximum efficiency (6.1 pints/kWh). Compared to most standard dehumidifiers (3.8 pints/kWh), the Dual 215 will save up to $2,000 per year in electricity. It is made in the USA. Optional condensate pump and ducting kits provide the ultimate in flexibility for the most challenging space restrictions and specialized applications. MERV-11 filtration is standard on these units, capturing particles (including mold spores) down to 1 micron in size. An additional Humidistat is required, we recommend the DEH 3000R Wall Mounted unit part #700833. Warranty: 1 year parts and labor. 5 year compressor and refrigerant system.
