Santa Fe In-Wall Dehumidifier (UltraMD33)

Description

Recognized as the first genuine in-wall dehumidifier, the UltraMD33 helps create a healthier, more comfortable indoor environment. Designed for spaces up to 1,200 square feet, it effectively removes up to 33 pints of moisture per day—ideal for individual rooms or multi-family residences. 

Built-In Dehumidification

Say goodbye to bulky, noisy portable dehumidifiers. The Santa Fe UltraMD33—previously known as the Ultra-Aire MD33—installs directly between wall studs, saving space while offering powerful moisture control. It’s a smart solution for apartments, hotels, and other compact living areas.

How It Works

Once installed, simply set your preferred humidity level on the electronic humidistat. The unit takes it from there, keeping humidity in check with minimal effort on your part. Air enters through lower vents on the front and sides, then exits through the top and upper side vents for effective circulation. To prevent tampering, the on/off button and humidity set point are tucked behind the diffuser—an ideal setup for spaces like hotels, senior communities, and anywhere controlled access is a plus.

Perfect For:

The UltraMD33 is a go-to choice for areas where space is tight and moisture control is essential:

• Condos & Townhomes

• Apartments

• Senior Living Facilities

• Student Housing

• Hotels

Beyond keeping humidity comfortable, it also helps prevent costly issues like mold, property damage, and guest complaints—making it both a comfort and a safeguard.

Installation

Built to fit snugly between two wall studs, this unit requires an opening measuring 14.5 inches wide by 30.25 inches tall. Because it needs to vent through both sides, installation must be done on an interior wall. You can either hardwire it into your home’s electrical system or use a standard 120-volt outlet—an optional 10-foot cord and plug is included for convenience. Depending on your setup, you may need to purchase a few extra accessories to complete the installation. Here’s when that might apply:

• No additional accessories are needed if penetrating both walls and the opposite side is a mechanical room.

• If the back wall is functional space, installation requires a 2x4 Wall Mount Bezel Kit (PN 4037767).

• If the other side of the wall goes into an unconditioned space, it may require the 2x4 Rear Panel Kit (PN 4037768) to add a layer of insulation to prevent condensation.

• For surface mount installation, the surface Mount Kit (PN 4037766) is required.

Note: While professional installation is recommended, it’s not required. Be sure to shut off your electrical breaker before installation. See the owner’s manual for additional installation directions and requirements.

Draining Made Simple

This unit comes with a 10-foot drain hose that connects directly to the drain port. You’ll need to route it through the interior wall cavity and into an HVAC AHU drain (which links to the HVAC drain pan) or another approved drainage outlet. Depending on the setup, the water can flow out by gravity, or you can install an external condensate pump to move it where needed. Once it’s in place, there’s no need to worry about emptying tanks or handling manual drainage—it runs on its own. Just make sure to review your local building codes before installation.
