What to check before choosing

Three questions: space, installation and drainage. You can change any answer.

Crawl space
Low framing, a narrow hatch and a remote drain can decide the installation before the headline pint rating does.
Basement
Start with the installation envelope. Then decide whether water can reach the drain downhill or needs a pump.
Whole home
A whole-home unit needs an installation plan. Tell us whether documented duct support is a requirement.

AlorAir Sentinel HD55P

A built-in-pump option for installations where a downhill drain is not available. The headline 120-pint figure is a hot, humid saturation rating; the same page lists 55 pints at 80°F and 60% RH.

AlorAir Sentinel HD55S

A low cabinet with gravity drainage. The source mixes HD55 and HD55S names, which makes checking the exact listing and generation especially important.

AprilAire E080

A documented 80-pint option at 80°F / 60% RH, with duct support and gravity drainage. Its 15-inch cabinet excludes feet and duct collars.

Santa Fe Compact70

A 12-inch-high cabinet makes this a candidate for a constrained installation. Its two published capacity figures also show why room temperature belongs in the buying decision.

Santa Fe Ultra70

The Ultra70 adds a ducted whole-home use case to a low cabinet. It is deeper than the Compact70, so a height-only shortlist can miss an important installation constraint.

Why these conditions matter

A useful shortlist starts with the space and the constraints that could rule out a model. We do not calculate a whole moisture load from square footage or pretend that missing specifications are known.

How this guide narrows the options

Each answer leads to a page with its own shortlist and explanation. You can open a later step directly, share the address or return to an earlier answer. Known conflicting specifications remove a model; missing facts stay in a separate check list.

What remains after the shortlist

Capacity at comparable conditions, minimum operating temperature, current model generation and installation clearance still matter. This guide organizes the documented options; the exact manual and installation assessment remain the final checks.

    Exact R32 SKU listing supplies the capacity and pump claim. Cabinet dimensions and operating range use the separately linked current R32 specification; do not transfer them from HD55S.

    Product heading, specifications: R32, gravity drain, 19.2 × 12.2 × 13.3 inches, operating temperature.

    URL and some body copy use HD55, while heading names HD55S. Verify exact SKU before buying.

    Spec rounds 43.7; manual registration gives 43.75. Manufacturer area ranges depend on different ceiling heights, not a universal moisture-load sizing formula.
