Sentinel HD35P
A compact 35 PPD AHAM-class unit aimed at smaller crawl spaces, with a built-in pump that makes it particularly useful when gravity drainage is inconvenient.

- Smaller crawl spaces up to the manufacturer’s published 1,000 sq ft range
- Installations where condensate must be pumped upward
- Low-temperature spaces that stay within the published operating range
- You need more than roughly a 35 PPD normalized capacity class
- You want higher-grade filtration
- Your space is large, loosely sealed or carrying a heavy moisture load
Compare capacities under the same test condition
CrawlClimate uses the 80°F / 60% RH figure as the primary comparison value when the manufacturer publishes it. Saturation figures are kept separate because they are measured under much warmer, wetter conditions.
What stands out
- 35 PPD at AHAM conditions is clearly separated from the 70 PPD saturation figure
- Built-in condensate pump with a long drain hose
- Compact 15.2 × 11.2 × 11.4 in body and published low-temperature operation
Potential limitations
- The 70-pint headline is a saturation figure; use the published AHAM rating for like-for-like comparison
- MERV-1 filtration is basic
- Published coverage should be checked against the actual moisture load
Before you order
The built-in pump is the main installation advantage: it can move condensate when a continuous downhill gravity path is unavailable. Still verify discharge height, hose routing and a suitable final drain location before ordering.
