AHAM PPD vs maximum PPD
This product has both AHAM and maximum/saturation moisture-removal ratings in the verified database. Maximum or saturation PPD is typically measured under more humid conditions, while AHAM PPD is a more standardized moderate-condition rating. Compare both values, but do not treat maximum PPD alone as proof that a unit is the right fit for a specific crawl space.
Drainage and pump setup
- Built-in pump
- No
- Drainage method
- Gravity drainage
- Drain hose length
- Not verified
Because this model does not have a verified built-in pump, a suitable gravity-drain path may be required unless another external condensate solution is used. That can be fine when the unit can drain reliably downhill.
A pump configuration is not universally better than gravity drainage. The practical choice depends on the crawl-space layout, drain route, and where condensate can safely discharge.
Coverage and sizing context
Manufacturer-reported maximum coverage
The stored manufacturer-reported maximum coverage for this model is 1,000 sq ft. This is not a DrySpace sizing guarantee. Crawl-space height, sealing, climate, airflow, moisture load, and water intrusion can all affect whether a product is practical for a specific space.
Manufacturer coverage statement: Size for 1000 sq.ft.

Verification notes
- Operating current and estimated power draw are not populated because the reviewed current first-party sources did not provide an operating-current value for this model.
- Warranty is not populated because the product page's 6-year marketing warranty language and the manual's staged warranty coverage are not identical.
