Namco P646-95 95-Pint Crawl Space Dehumidifier – 1,300 sq ft, Auto Pump-Out

The Namco P646-95 removes up to 95 pints of moisture per day at 728 watts, covering up to 1,300 square feet with an automatic pump-out and digital humidity controls. At 81 lbs and 20" × 15" × 25", it is the most compact and lightest unit in the P646 series—appropriate for smaller crawl spaces, tight basement corners, and single-zone humidity control in residential and light commercial applications.

P646-95 Capacity, Power Consumption, and Dimensions

  • Capacity: 95 pints/day — handles standard residential crawl spaces and basements with moderate chronic humidity problems.
  • Coverage area: up to 1,300 sq ft — appropriate for residential crawl spaces under 1,300 sq ft or as one of multiple units in larger spaces.
  • Power consumption: 728W at 6.75A — lowest energy draw in the P646 series; lower operating cost for continuously running installations.
  • Weight: 81 lbs — lightest in the P646 series; easier to carry into restricted-access crawl spaces and position without mechanical assistance.
  • Dimensions: 20" × 15" × 25" — smallest footprint in the P646 series; fits in the most confined access points.
  • Auto pump-out — continuous drainage to hose or floor drain; no manual bucket emptying.
  • Digital controls — programmable humidity setpoint with LCD monitoring.

When to Choose the P646-95 vs. the P646-150 or P646-190

The P646-95 is the entry point in the P646 compact series. For crawl spaces under 1,300 sq ft with chronic humidity problems in moderate-humidity climates (Pacific Northwest, Midwest, parts of the Northeast), the P646-95 provides sufficient capacity to maintain target RH levels continuously. In high-humidity climates (Gulf Coast, Southeast Atlantic) or crawl spaces with active water seepage, the P646-95 may be insufficient to reach target humidity—the P646-150 or P646-190 would be more appropriate. The P646-95's 728W draw makes it the lowest-cost unit to operate continuously, which matters when a machine runs 24/7 for months at a time during post-flood structural drying or chronic high-humidity seasons.

Compact Installation for Residential Crawl Spaces

Most residential crawl spaces have 18–36 inch clearance heights and access openings of 18 × 24 inches or larger per code. The P646-95 at 20" × 15" × 25" passes through standard access openings and operates in spaces with less than 30 inches of clearance. Installation requires positioning the unit on a flat, stable surface within the crawl space, routing the drain hose to a suitable drainage point (sump pit, floor drain, or gravity-fed exterior exit), and connecting to a 15A outlet. Most installers also encapsulate the crawl space vapor barrier before installing a dehumidifier, as this significantly reduces moisture load on the machine and reduces operating hours required to maintain target RH.
