NOTE: This unit is only available to contractors for professional installation

The compact, high-efficiency Ultra-Aire 70H (4033730) is designed for tight, low-clearance, shallow spaces, where most dehumidifiers cannot fit.

The Ultra-Aire 70H is the first compact, high-efficiency, whole-house ventilating dehumidifier designed to fit in tight, low-clearance applications. The unit removes up to 70 pints per day, is Energy Star® rated and provides effective air filtration (MERV 11). The Ultra-Aire 70H is designed to handle up to 1,800 sq. ft, which makes it ideal for a small home, condo, or apartment application. The unit can be tied into a forced air duct system, ducted with separate ducting, or used in a freestanding application. It can be installed in mechanical rooms, closets, attics, basements, and crawlspaces.

The Ultra-Aire 70H has an innovative cabinet design that easily converts to either vertical or horizontal airflow discharge which allows for easier installation in tight spaces. Flexible airflow configurations allow the Ultra-Aire 70H to be installed in locations where other dehumidifiers don’t fit due to duct issues and size constraints.

Fresh Air Ventilation

Optional fresh outdoor air may be ducted to the unit via a “T” to the inlet duct. This provides fresh air to dilute pollutants and maintain a normal oxygen content in the air. The amount of fresh air ventilation can be regulated by a variety of dampers and controls.

Air Filtration

The Ultra-Aire 70H includes air filtration to improve indoor air quality. A MERV 11 media filter is standard. An optional external MERV 14 filter box and deep pleated 95% media filter is available for optimum air filtration and to reduce potentially harmful airborne particles. If the optional filter is chosen, a standard filter operates as a prefilter.
