Dapper Supply DP-CD1131 Commercial Dehumidifier – 350 PPD, Built-In Pump, 30,000 Sq Ft, ETL

DP-CD1131 350-PPD Dehumidifier for Large-Loss and Industrial Drying

The DP-CD1131 removes up to 350 PPD (176 PPD AHAM at 80°F/60% RH) and moves 750 CFM across spaces up to 30,000 sq ft. A built-in pump lifts condensate 16.4 ft, backed by a 2-gallon tank and a 3.28 ft gravity hose. Its 176 PPD AHAM rating clears the LGR threshold that maps to Xactimate code WTRDHM>XL. It draws 1450W on a 220V circuit.

350 PPD, 750 CFM, and 16.4-Ft Pump Lift

• 350 PPD moisture removal (176 PPD AHAM) — top-of-range output for the largest water losses and warehouse humidity control, with 420 PPD at saturation
• 750 CFM airflow across 30,000 sq ft — single-unit coverage for distribution centers, gymnasiums, and industrial floor plates
• 16.4-ft pump lift — continuous automatic drainage to elevated sinks, windows, or drain lines
• 2-gallon tank and 3.28 ft gravity hose — a gravity drain runs alongside the pumped removal for flexible setup
• 10–90% RH control, 41–95°F range — holds setpoint from flood drying down to maintenance humidity
• R32 refrigerant with rotary compressor — 1450W (220V/6.8A) draw with auto-restart, auto-defrost, and overload protection
• Steel housing, 60 dB single-speed fan — washable filter and industrial-grade chassis for long-term deployment

DP-CD1131 Applications and Environments

Large-loss restoration contractors specify the DP-CD1131 for commercial water losses in big-box retail, school gymnasiums, and hospital wings, where a single high-capacity unit cuts equipment deployment logistics and the 176 PPD AHAM rating supports Xactimate WTRDHM>XL billing. Cold-storage managers deploy it in staging and receiving areas where repeated door openings drive sustained high humidity through warm months. Manufacturers run it in production areas where humidity above 50% RH causes failures in coatings, adhesives, and precision assembly. Convention centers and event venues use it for humidity management in large exhibit halls during high-dew-point periods. The 750 CFM airflow and 30,000 sq ft rating are what let one DP-CD1131 stand in for several smaller units on a large loss, which cuts the number of machines a crew has to haul, power, and monitor on site. It draws 1450W on a 220V circuit rather than a standard 115V outlet, so confirm the receptacle before deployment. The 16.4-ft pump lift drains continuously to an overhead line, backed by the 2-gallon tank and gravity hose for setups where a pumped run does not reach. Auto-restart, auto-defrost, and overload protection keep it running unattended through the long duty cycles these jobs demand. The unit measures 25.5 × 16.9 × 62 in, weighs 183 lb, and is backed by a 1-year parts and labor warranty.
