Since cold air holds less moisture, it’s challenging in the winter months to maintain a comfortable humidity level while blasting the heat – protect your health and your home by installing the General Aire Model 4200 Bypass Evaporative Humidifier. As warm air from your furnace flows into the humidifier, it meets a water-soaked vapor pad, which evaporates that moisture into the air to deliver humidity all throughout your home.
Note: This humidifier must be installed by a licensed contractor.
Manual or Automatic
The General Aire 4200 is available with two different operating controls:
- General Aire 4200M: The bypass humidifier includes an MHX3C humidistat to install on your wall or the duct, with manual controls to adjust the humidity range.
- General Aire 4200A: This GFX5 Automatic Digital Humidistat controls the furnace blow motor and includes an easy-to-read LCD screen, an outdoor sensor, and accurate humidity readings. It can be installed directly on your wall or the duct, giving an extended humidity range from 10 percent to 75 percent.
Flexible Installation
Installation is easy and customizable with this General Aire bypass humidifier, allowing a contractor to install it on either the return or supply air plenum. The bypass panel can be reversed to point either to the left or right, which is a great convenience if you have a tight space on one side of your furnace.
Additional Features
- Large Coverage Area: This evaporative humidifier covers homes up to 4,200 square feet.
- Contemporary Design: This whole-house humidifier features an innovative, space-saving design and is lightweight and easy to install.
- Vapor Pad Replacement: Designed with a sturdy “pull apart” frame, the cover lifts off easily and snaps in place for a quick replacement routine.
- Strong Construction: General Aire uses UV-stable automotive-grade plastic for this low-profile humidifier.
- Water Supply: A stainless steel tube distributes cold or hot water from the direct line hookup.
Summary
Maintain a comfortable level of humidity year-round in your home with this General Aire evaporative humidifier, equipped with a low-profile design, easy-to-replace vapor pads, and available with either a manual or automatic humidistat.
