Dapper Supply DP-CD1131: 350-Pint Commercial Dehumidifier for 30,000 Sq Ft Coverage

The Dapper Supply DP-CD1131 is the highest-capacity unit in Dapper Supply's commercial dehumidifier line, removing up to 350 pints per day across spaces up to 30,000 square feet. A built-in pump with drain hose handles continuous condensate removal, while dual-speed fan operation allows operators to balance drying speed against energy consumption during extended deployments.

350-Pint Capacity, Continuous Drainage, and ETL Certification

  • 350 pints per day removal capacity — top-of-range output for the largest commercial water losses, warehouse humidity control, and flood recovery operations
  • Built-in pump with continuous drainage — automatic condensate removal for unattended 24/7 operation without manual intervention
  • 30,000 sq ft coverage area — single-unit specification for very large commercial floor plates, distribution centers, and industrial facilities
  • 2-speed fan operation — high speed for aggressive drying; low speed for energy-optimized maintenance dehumidification after dry-down
  • ETL Certified — meets commercial equipment safety standards recognized by building codes and insurance requirements
  • Heavy-duty commercial construction — designed for daily repositioning on restoration job sites and long-term industrial deployment
  • Improves indoor air quality — sustained humidity control below 50% RH inhibits mold growth and protects moisture-sensitive materials and equipment

Facilities Specifying 350-Pint Dehumidification: Large-Scale Restoration and Industrial Operations

Large-loss restoration contractors specify the DP-CD1131 for commercial water losses in big-box retail stores, school gymnasiums, and hospital wings where a single high-capacity unit reduces equipment deployment logistics. Cold storage facility managers deploy it in staging and receiving areas where repeated door opening creates sustained high-humidity conditions during warm months. Industrial manufacturers use it in production areas where ambient humidity above 50% RH causes quality failures in coatings, adhesives, and precision assembly. Convention centers and event venues use it for humidity management in large exhibit halls during seasonal high-dew-point periods.

Frequently Asked Questions

How many gallons per day does 350 pints represent?
350 pints equals 43.75 gallons of water removed per day — approximately 1.8 gallons per hour at rated capacity. This is one of the highest portable dehumidifier outputs available in a single commercial unit.
What type of commercial water loss events require a 350-pint dehumidifier?
Large Category 1–2 commercial losses covering 3,000–6,000+ square feet of wet materials — flooded gymnasium floors, retail store slab-on-grade water intrusion, or multi-office floor commercial pipe breaks — typically specify a 350-pint unit as the primary dehumidifier.
How does the DP-CD1131 compare to the DP-CD1130 (290 PPD)?
The DP-CD1131 removes 60 more pints per day and covers 6,000 more square feet than the DP-CD1130. Both use a built-in pump and dual-speed fan. The DP-CD1131 is the better choice for very large floor plates or high-moisture-load environments.
Can mold grow while this unit is running?
Mold requires relative humidity above approximately 60% RH to grow. If the DP-CD1131 maintains the environment below 50% RH, new mold growth is effectively inhibited. However, it does not remediate existing mold — only prevents new colony development.
Does continuous 24/7 operation at 350 PPD create heat?
Yes. All dehumidifiers generate heat as a byproduct of the refrigeration cycle — typically 10–15°F above ambient. In enclosed spaces, this heat accumulation can increase ambient temperature and slightly reduce dehumidification efficiency. Ventilation or air conditioning in conjunction with dehumidification is recommended for temperature-sensitive restoration jobs.
What circuit amperage does the DP-CD1131 require?
Contact us or review the product spec sheet for exact amperage draw. High-capacity commercial dehumidifiers in the 290–350 PPD range typically require a 15–20 amp dedicated circuit at 115V. Do not share a circuit with other high-draw restoration equipment.
Is the DP-CD1131 suitable for outdoor or semi-outdoor use?
The DP-CD1131 is rated for indoor commercial use. Use in semi-outdoor environments such as covered loading docks is possible if ambient temperature stays within the 41°F–95°F operating range, but prolonged exposure to rain or direct moisture is not recommended.
