Abestorm Guardian SN35P

Abestorm markets the Guardian SN35P for crawl spaces and basements. Its 35-pint AHAM claim is recorded separately from its 70-pint saturation output. It has a built-in condensate pump.

Abestorm Guardian SNS65 — manufacturer product photograph

Abestorm markets the Guardian SNS65 for crawl spaces and basements. Its 55-pint AHAM claim is recorded separately from its 120-pint saturation output. It has a built-in condensate pump. The model name includes 65, but the specification table states 55 pints at AHAM.

AlorAir Sentinel HD35P

This 35-pint rated model provides manufacturer-described pump and gravity drainage modes. The pump may help when the drain is above the unit, but discharge height and the chosen mode need an installation check.

AlorAir Sentinel HDi65S

The HDi65S page states 55 pints per day at 80°F and 60% RH, so the digits in the name must not be used as its capacity. Its drainage specification provides both pump and gravity routes.

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.

Why these conditions matter

Crawl space models with a documented built-in pump, checked against cabinet no taller than 14 in.; missing required facts are labeled separately. Compare the exact specifications and complete the manual-based installation checks before ordering.

Check the pump-equipped generation

Sentinel HD55P has documented built-in pumping for crawl spaces and basements. HD55S is a gravity-drain variant. Do not treat the shared HD55 name as proof of the same drain hardware.

No confirmed candidate is useful information

If the selected installation has no confirmed model in our small catalog, keep that result visible. Missing cabinet or duct facts appear separately; a known mismatch does not. Change the arrangement or obtain the exact missing specification before ordering.

A short cabinet is not a complete fit

Compact70 and Ultra70 both have documented 12-inch cabinet heights. Their depths are 21 and 28 inches respectively. Measure the hatch, turns and final location before choosing either.

Check the supporting sources ↓

Solve the moisture source as well

Record water entry, drainage outside the house and the condition of the ground cover. A dehumidifier shortlist does not diagnose a leak or approve an encapsulation plan.
