The catch
AlorAir Sentinel HDi90 Ductable
Higher and wider, the body weighs 70.5 lb. Pump servicing and exact HVAC compatibility are still important checks.
Side by side
AlorAir HDi90 vs AprilAire E100: E100 has the higher matched rating, HDi90 includes pumping
Quick verdict
HDi90 Ductable is the choice when an internal pump solves a verified uphill drain route and the dedicated-space setup fits. E100 is the choice when its documented duct integration and higher matched-condition rating meet the design. Under matched warm conditions E100 is rated at 100 pints against 90 for HDi90. The 198-pint saturation figure of AlorAir is not comparable to the 100 of AprilAire. E100 still needs a separate pump if water cannot drain downhill.
Before you buy
Why, and what it costs you
Once conditions are matched, the 198-pint headline flips
The 198-pint claim for HDi90 is reached at 90 F and 90% RH. At 80 F and 60% RH its figure is 90 pints, and E100’s is 100 under those conditions. So the nominal difference that counts is ten pints, in E100’s favor. The correction is important for anyone trying to size a basement from a retailer title. Neither number predicts how much will be collected in a cooler home, and neither removes the need to calculate the actual moisture load.
Where this comes from
Both ratings are normalized to 80 F and 60% RH. 100 minus 90 gives ten pints. Saturation figures that do not match are not compared.
The catch
AprilAire E100
An onboard pump and drain hose are missing from the standard E100 package. Extra drainage parts may be needed.
AlorAir Sentinel HDi90 Ductable
- Why pick it
- The included pump takes care of the main installation problem, and you can maintain it.
- The complete airflow and service plan works better with its shorter body.
- The catch
- Higher and wider, the body weighs 70.5 lb. Pump servicing and exact HVAC compatibility are still important checks.
AprilAire E100
- Why pick it
- Your design needs the 100-pint class and documented HVAC integration.
- A lower, narrower, lighter body makes access easier, and gravity drainage or a separate pump is planned.
- The catch
- An onboard pump and drain hose are missing from the standard E100 package. Extra drainage parts may be needed.

What this page compares
AlorAir HDi90 Ductable vs AprilAire E100 for a pump-dependent crawlspace or ducted home, weighed on real rating conditions, access and the maintenance that remains.
On the same moisture-control job, these high-capacity crawlspace and basement alternatives overlap. It is easy for their different rating conventions and included drainage hardware to distort the decision.

In practice
Differences you will notice
Once conditions are matched, the 198-pint headline flips
The 198-pint claim for HDi90 is reached at 90 F and 90% RH. At 80 F and 60% RH its figure is 90 pints, and E100’s is 100 under those conditions. So the nominal difference that counts is ten pints, in E100’s favor. The correction is important for anyone trying to size a basement from a retailer title. Neither number predicts how much will be collected in a cooler home, and neither removes the need to calculate the actual moisture load.
How we worked this out
Both ratings are normalized to 80 F and 60% RH. 100 minus 90 gives ten pints. Saturation figures that do not match are not compared.
A pump may cut installation work but add service work
With a raised drain, HDi90 comes with a component that E100 lacks. The materials list may get simpler, but the manual still calls for annual pump maintenance and for draining the reservoir before moving or storage. A working gravity route lets E100 skip that pump routine. If E100 gets an external pump, the routine just moves to another component. When a household picks a hidden installation, whoever does the maintenance must be able to reach the pump, filter and hose connections.
How we worked this out
Included hardware, set against drain height and service access. No advantage in pump reliability or maintenance time is inferred.
A lighter body may count for more than which unit is shorter
E100 weighs 6.5 lb less, stands 2.7 inches lower and is 1.2 inches narrower. HDi90 is 2.8 inches shorter. A low, narrow access route may be easier to handle with E100, whereas a short final bay may favor AlorAir. More room than the bare body is needed for both. E100 needs 15 inches for side filter withdrawal, and HDi90 specifies inlet and discharge clearances. Measure the route and the service position before deciding which shape fits.
How we worked this out
Exact differences in the bodies, set against the transport route and installed service access. No claim is made about a safe personal lifting weight.

Spec by spec
Where they really differ
| Spec | AlorAir Sentinel HDi90 Ductable | AprilAire E100 | In practice |
|---|---|---|---|
| Matched rating | 90 pints at 80 F and 60% RH | 100 pints at 80 F and 60% RH | On this common basis, E100's stated rating is the higher one. |
| Included pumping | Internal pump | No internal pump | Uphill drainage is still a task with the higher capacity. |
| Body height and weight | 17.7 inches, 70.5 lb | 15 inches, 64 lb | E100 stands 2.7 inches lower and weighs 6.5 lb less. |
| HVAC evidence | Ductable, exact fan-interlock route not established | Documented duct and fan-interlock instructions | Go for a verified complete system and not a connection label. |
Trade-offs
What each pick costs you
With AlorAir Sentinel HDi90 Ductable
- Before movement or storage the pump reservoir has to be drained, and annual pump care still applies.
With AprilAire E100
- Sitting outside the unit does not make a separate pump maintenance-free.
Change of plan
When the answer changes
The main dedicated-space constraint is resolved by included pumping
Go with AlorAir Sentinel HDi90 Ductable. The internal pump is HDi90's.
What decides it is matched capacity and the documented HVAC design
Go with AprilAire E100. E100 comes with the higher rating and integration instructions.
Decision guide
Before you buy
Enough drying capacity with less installation work is the goal, though the larger headline number can go with the lower matched rating.
What this page can’t tell you
- There is no measured winner on field drying speed, energy bill or noise. Interlock support that is unknown for AlorAir is not treated as proven to be absent.
