The AlorAir Sentinel HDi90 Duct-able Version is a crawl space and basement dehumidifier built for ducted installs, with a built-in condensate pump. It removes 90 pints of water a day at AHAM conditions (80°F, 60% RH) and up to 198 pints a day at saturation (90°F, 90% RH), for spaces up to 2,600ft², on a 5.56 A draw.
Its round intake carries a pre-filter and a MERV-8 filter, and dry air leaves through a 6" supply collar. That lets the Sentinel HDi90 Duct-able sit in the unfinished side of a basement or crawl space and keep a finished room dry, pumping its condensate to the nearest drain.
Features
Built for Ducted Installs
A 6" supply adapter comes standard for ducting dry air into another room, with a 12" return collar and a 72" flexible supply duct available as accessories.
Pre-Filter and MERV-8 Filter
The round intake holds a pre-filter and a MERV-8 filter that keep crawl space dust off the rare earth alloy tube evaporator.
Built-In Condensate Pump
Pumps water out through the included drain hose. If the pump stops, a high water sensor shuts off the compressor and shows E4.
90 Pints a Day at AHAM
Up to 198 pints a day at saturation, from 210 CFM of airflow and a rotary compressor, rated at 2.69 L/kWh.
Automatic Humidity Control
The integral humidistat holds any setpoint from 36% to 90%, with continuous mode below 36%.
Auto Defrost and Memory Restart
Keeps working down to 33.8°F with automatic defrost, and resumes its settings after a power cut.
Optional Wired Remote
AlorAir's remote connects on a 25' CAT 5 cable and has its own humidity sensor, so it can control the unit from the room being dried.

Setup & Placement
Place the unit in the unfinished area near where the drain hose can run, and duct dry air into the finished space. AlorAir suggests a return grille or passive vent in the dividing wall so air can circulate back, and keeping interior doors open. Stand the unit level on blocks or pavers, not on the vapor barrier, and wait 2 hours before switching on if it was tipped.
Fit the drain hose to the compression fitting on the discharge end and route it to a drain or outside. Allow 12" of clearance at the inlet and 36" at the discharge, and plug into a grounded 15 A GFCI circuit.

About AlorAir
AlorAir Solutions is based in Chino, California, and supplies dehumidifiers, air movers and air scrubbers for crawl spaces, basements and water damage restoration. Its Sentinel line is built for permanent installation in the spaces under and around a home.
The Duct-able Version sits alongside the standard Sentinel HDi90, which has the same pump and capacity, and the HD90, which drains by gravity. The Sentinel HDi100 and HDi120 step up to 100 and 120 pints a day at AHAM and take 10" flex duct on both the inlet and the supply.
