Candidates match the selected documented conditions. Capacity, service access and accessory compatibility still need checking.

Select 2–10 candidates to compare their specifications.

Abestorm Guardian SNS120

A pump-equipped 120-pint-rated Guardian intended for crawl spaces, basements and ducted whole-home installations. Current manufacturer sources disagree on cabinet dimensions and AHAM temperature, so verify the exact model drawing before sizing a tight installation.

Cabinet height: Not verified
Drain arrangement: built in pump

Built-in pumpDuct connection

Manufacturer lists whole home use.
Built-in pump documented; check lift and hose limits.
Duct connection documented; check collars and the approved layout.

AlorAir Sentinel HDi100

The HDi100 catalog separates a 100-pint AHAM rating from a 220-pint saturation claim. It uses pump drainage and a larger chassis than the smaller Sentinel units; the installed footprint and discharge route need checking.

Cabinet height: 17.9 in.
Drain arrangement: built in pump

Built-in pumpDuct connection

Manufacturer lists whole home use.
Built-in pump documented; check lift and hose limits.
Duct connection documented; check collars and the approved layout.

AlorAir Sentinel HDi120

A larger pump-equipped Sentinel model whose catalog lists 120 pints per day at AHAM and 235 pints at saturation. The manufacturer describes ductable use, but the appropriate kit and rated installation conditions still need verification.

Cabinet height: 17.9 in.
Drain arrangement: built in pump

Manufacturer lists whole home use.
Built-in pump documented; check lift and hose limits.

Why these conditions matter

Whole home models with a documented built-in pump, checked against duct connections are required; 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.

Do not infer an HVAC layout from a product label

The base AprilAire E080 and E100 document duct connections; Ultra70 also supports ducted arrangements. Connection support alone does not determine which HVAC layout is suitable.

Ask for the complete installation plan

Record the air paths, humidity control, drain route and proposed service access. Have the installer check the exact manual before ordering collars, dampers or other accessories.
