The catch
AlorAir Sentinel HDi90 Ductable
According to the manual, its Central Control key does not apply to this model. Having a duct collar does not prove HVAC integration.
Side by side
AlorAir HDi90 vs AprilAire E080: E080 has the documented HVAC route, HDi90 includes a pump
Quick verdict
HDi90 Ductable suits a pump-dependent dedicated-space installation where its larger, heavier cabinet and service needs fit. The pump is included with HDi90, whereas E080 needs a separate one for uphill drainage. E080 suits a job that requires its documented HVAC connection and fan-interlock route. The ductable label of AlorAir does not by itself establish that integration. Compare 90 versus 80 pints at 80 F and 60% RH, and leave out the separate 198-pint saturation figure of AlorAir.
Before you buy
Why, and what it costs you
The included pump settles one bottleneck and leaves another one to verify
When the crawlspace drain has to go uphill, HDi90’s internal pump can spare you from sourcing a separate condensate pump, as long as the permitted route is confirmed. If the same appliance also has to connect to the home’s HVAC fan, a ductable label is not enough. The HDi90 manual explicitly says the Central Control key does not apply to this model. E080 comes with a documented HVAC route and fan-interlock instructions, but when gravity will not work it needs a separate pump. Pick the complete installation that covers both jobs.
Where this comes from
Whether a pump is included and which control instructions are verified, set against elevated disposal and HVAC integration. AlorAir compatibility that is unverified is not declared impossible.
The catch
AprilAire E080
There is no onboard pump. Separate equipment and appropriate controls are needed for an uphill route.
AlorAir Sentinel HDi90 Ductable
- Why pick it
- Gravity drainage cannot reach the disposal point, and you have verified the included pump route.
- Your dedicated-space installation can handle the 17.7-inch-high, 70.5 lb body and pump maintenance.
- The catch
- According to the manual, its Central Control key does not apply to this model. Having a duct collar does not prove HVAC integration.
AprilAire E080
- Why pick it
- Your project calls for the documented HVAC fan-interlock arrangement.
- The lower, narrower cabinet and ten-inch duct design work for you, and you plan drainage separately.
- The catch
- There is no onboard pump. Separate equipment and appropriate controls are needed for an uphill route.

What this page compares
AlorAir Sentinel HDi90 Ductable vs AprilAire E080 for a crawlspace or ducted home, weighed on pumping, HVAC controls, service access and matched capacity.
Each is a permanent-installation alternative for moisture control in a crawlspace or basement. Different installation bottlenecks are solved by the pump-equipped AlorAir and the duct-integrated AprilAire.

How we worked this out
Whether a pump is included and which control instructions are verified, set against elevated disposal and HVAC integration. AlorAir compatibility that is unverified is not declared impossible.
Even a hidden pump has to be reachable
Annual pump maintenance, and draining the reservoir before the unit is moved or stored, are called for in HDi90’s manual. So its pump swaps repeated water handling for a different service task. If getting to the unit means crawling past stored equipment, keep access open for that work. E080 avoids an onboard pump only when a gravity route is available. An external pump added to it shifts the maintenance elsewhere and does not eliminate it.
How we worked this out
Pump care instructions, set against difficult crawlspace access. Maintenance is treated as moved elsewhere and still present.
Line up the ratings at the same temperature before you pay for capacity
At 90 F and 90% relative humidity AlorAir lists 198 pints, and at 80 F and 60% it lists 90 pints. AprilAire’s 80-pint rating uses the latter warm conditions. A nominal gap of ten pints, and not 118, is what can be defended. Even that ten-pint difference says nothing about the actual drying speed of a crawlspace. The job is still governed by temperature, incoming moisture and the air route, so the differences in pump and integration may decide more than the rating.
How we worked this out
Normalizing the rating conditions: 90 minus 80 gives ten pints at matched conditions. No calculation of home runtime is made.

|---|---|---|---|
| Comparable rating | 90 pints at 80 F and 60% RH | 80 pints at 80 F and 60% RH | Different conditions lie behind the 198-pint AlorAir headline. |
| Drainage | Internal condensate pump | Gravity or separate pump | How high the disposal point sits can decide the practical setup. |
| HVAC route | Ductable, Central Control key not applicable in manual | Documented connection and fan-interlock instructions | Treat absent integration evidence as a thing to verify before purchase, never as a capability. |

Trade-offs
What each pick costs you
With AlorAir Sentinel HDi90 Ductable
- Cleaning the pump and draining the reservoir before moving or storage are still jobs that come with ownership.
With AprilAire E080
- Put the drain hose, optional pump and required installation controls into the total.
Change of plan
When the answer changes
The main requirement is a verified internal-pump route
Go with AlorAir Sentinel HDi90 Ductable. That component comes with HDi90.
Essential: verified HVAC interlock and connection instructions
Go with AprilAire E080. The documented route is E080's.
Decision guide
Before you buy
One appliance to simplify the job is the goal, but pumping water and tying into the house fan are separate requirements.
What this page can’t tell you
- It is not claimed that AlorAir cannot support a custom installation. The exact supported control route has to be established before you rely on it. There is no saturation-versus-AHAM ranking.
