Moiswell Marshal WD160

A ductable whole-home model with a fresh-air intake, convertible outlet and gravity drain. The manufacturer advertises 65 rated pints and 160 maximum pints but labels the rated standard inconsistently, so compare it cautiously.

1 model needs another check

These satisfy the known constraints but have a missing fact. They are separate from the confirmed shortlist.

Santa Fe UltraMD33 ↗

Verify the required duct connection.

Why these conditions matter

Documented whole home candidates for duct connections are required and a proposed continuous downhill condensate route. Compare the exact specifications and complete the manual-based installation checks before ordering.

A downhill route still needs a manual check

The drain outlet, any required trap, mounting height and drain destination determine whether the route works. Do not assume that all gravity-drain models use the same trap arrangement. Record the entire run before buying.

What this shortlist confirms

The documented models below meet the selected whole home use and cabinet or duct constraints and document gravity drainage. A continuous downhill route is your proposed installation condition, not something we can verify remotely.

Check the supporting sources ↓

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.

Check the supporting sources ↓

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.
