Helios D35 weighs less. It is 45.37 lb lighter than Sentinel HDi90.
Weight alone cannot establish fit; allow the unit’s full dimensions and service clearances in your crawl space.

Use AHAM capacity rather than mixing capacity labels
AlorAir Helios D35 and Sentinel HS35 both carry an AHAM capacity of 35 pints per day. Galaxy 60 carries 60 pints per day, while Sentinel HD90 carries 90 pints per day. AlorAir's capacity and coverage ratings are compared with handling weight; there are no moisture-removal trials or determinations of drainage fit or maintenance access for your installation. Keep that named rating basis attached to the figures; another capacity label on a product page cannot be substituted.
AHAM capacities span 35 to 90 pints per day across these 10 units. The figure does not predict water removal in your crawl space, where the operating conditions need to be considered separately.
Matching capacity can still mean a different carrying weight
Helios D35 weighs 25.13 lb; Sentinel HS35 weighs 37.8 lb. Both carry AlorAir's 1000-square-foot coverage rating. Their different weights matter when planning access, but weight and coverage do not provide cabinet dimensions or installation clearances.
Coverage ratings across the units span 1000 to 2600 square feet. Use the maker's sizing and installation documentation for the actual space rather than treating the coverage figure as a promise for every moisture load.
Drain routing needs more than a model-name suffix
The capacity, airflow and weight fields do not specify pump inclusion, drain routing or service clearance. Even Galaxy and Sentinel model suffixes cannot answer what is included in the exact drainage package; read its installation documentation.
Before you buy
Which moisture-removal figure should I compare?
Use the AHAM rate rather than mixing it with saturation claims. Sentinel HDi65S gives 55 pints/day at 80°F and 60% relative humidity, alongside 120 PPD at 90°F and 90%. The different conditions explain why these ratings cannot be used interchangeably. AlorAir's Helios D35 weighs 25.13 lb at an AHAM rating of 35 pints/day; Sentinel HDi90 weighs 70.5 lb at 90 pints/day.
Does rated floor area tell me the unit will fit?
AlorAir claims up to 2,600 sq ft for Sentinel HD90 and HDi90. That is a coverage claim, not a physical dimension. This page has no unit dimensions or service-clearance figures; compare the entry opening and installed space with the exact model's dimensions and installation instructions. The difference is 45.37 lb. For lower weight, D35 is lighter in this pair. Physical fit still needs the unit's dimensions and service clearances.
Which models mention a condensate pump?
The source titles mention pumps for Sentinel HD55P, HDi90 and Galaxy 60P. Pump lift, discharge routing and included hose contents are not compared here. Read the exact unit's package contents and drainage instructions before you buy; the airflow figure does not describe a pump.
