Ultra-Aire 120V Engineering Specifications

Ultra-Aire 120V

A new spin on the original. The Ultra-Aire 120V replaces the Ultra-Aire 100V as the industry’s only vertical whole house dehumidifier. The small-footprint and innovative dual-exhaust design make it ideal for basements, mechanical rooms and large attics where floor space is limited.

Ultra-Aire 120V Dedicated Return to HVAC Supply Installation
(Alternate Install Options)

Ultra-Aire 120V Dedicated Ultra-Aire Return to HVAC Supply Installation

  • Install a dedicated 8″ air return for the Ultra-Aire 120V from a central area of the structure
  • Install an insulated duct from outside to the 6″ damper of the Ultra-Aire 120V to provide fresh air ventilation (optional)
  • The optional second supply of the Ultra-Aire 120V may be ducted to another location, this can provide a second source of airflow to the basement or supply of the existing HVAC system with a backdraft damper
  • When using only one of the two supplies on the Ultra-Aire 120V, the unused supply must be blocked using the duct cover plate included
  • If the existing system has multiple returns, instead of installing a dedicated return to the Ultra-Aire 120V, it is possible to select one to disconnect from the existing HVAC system and use it for the dedicated Ultra-Aire 120V return
  • Select a return from a central location in the house that is always open to the rest of the structure
  • DO NOT use a return from a room where doors are kept closed
  • DO NOT locate return in a bathroom or kitchen
  • Control should be located remotely from the dehumidifier and placed in a central location

Ultra-Aire 120V Mechanical Closet Installation — Central Return to HVAC Supply
(Alternate Install Options)

Ultra-Aire 120V Mechanical Closet Installation

  • Locate the dehumidifier under or next to the HVAC system as space allows
  • A passive vent or louver door is required to allow air to be pulled in from the living space
  • No inlet duct is required. Air is pulled through the passive vent or louver door from the living space
  • Where outlet space is restricted, the outlet duct collar is optional
  • Install an insulated duct from outside to the 6″ collar of the Ultra-Aire 120V to provide fresh air ventilation (optional)
  • Duct the supply of the Ultra-Aire 120V to the supply of the existing HVAC system with a backdraft damper
  • Control should be located remotely from the dehumidifier and placed in a central location

The Energy Star® rated Ultra-Aire 120V features high capacity performance, removing up to 120 pints per day. It offers a superior level of air filtration (MERV 13) with dedicated fresh air mechanical ventilation for residential homes up to 3,000 square feet. The integral filter housing holds up to 6″ of air filter media, allowing for a variety of filtration options, including MERV 14, without the need for additional equipment. The unique vertical configuration, small-footprint, and innovative dual-exhaust make installation and maintenance much easier in applications where floor space is limited.

Optional fresh outdoor air may be ducted to the unit via a six inch round duct. This provides fresh air to dilute indoor pollutants and maintain high oxygen content in the air. The amount of fresh air ventilation can be regulated by a variety of dampers and controls.

The Ultra-Aire 120V includes air filtration to improve indoor air quality. An optional MERV 14 deep pleated 95% media filter is available for optimum air filtration to reduce potentially harmful airborne particles.

The Inside Story On Humidity & Fresh Air

border-2746x87

Did You Know?

Overcooling your home to control humidity will make you feel uncomfortable and raise your utility bill.

Ultra-Aire dehumidifiers help reduce the risk of serious health issues through filtration, ventilation, and moisture control.

Lowering your AC to dehumidify your home can cause condensation resulting in mold.

Ultra-Aire dehumidifiers provide superior indoor air quality through fresh air ventilation and humidity control.
