Dave Lennox Signature® Collection Variable Speed Air Handler
Innovation never felt so good.™

Offers greater cooling

­efficiency when matched with specific air conditioners or heat pumps

More efficient operation reduces electric consumption and conserves resources

Factory-installed MERV 16 media filter provides healthier indoor air and reduces the space required for installation

Emits no ozone into the air

Slow-ramping heating-mode blower offers greater comfort, eliminating uncomfortable “cold blow”

Every air conditioner or heat pump needs an indoor unit to blow conditioned air through the home, and there are several to choose from. Typical air handlers simply circulate heated or cooled air through the air duct system. The CBX40UHV does this plus so much more.

The quietest and most efficient air handler you can buy.*

In heating mode, the CBX40UHV increases airflow slowly, virtually eliminating the “cold blow” common with some air handlers. Low-speed operation helps keep sound to a minimum. What’s more, a built-in filtration system helps clean the air of allergy-aggravating particles. This innovative air handler delivers

comfort­ that’s efficient, quiet and healthy—everything you expect from Lennox.

Humidity control maximizes comfort

SilentComfort™ technology reduces noise

Warranty

10-year limited warranty on covered components.

Comfortable

Blowing away the competition

The CBX40UHV slowly ramps up, instead of starting at full speed, to allow the coil temperature to get hot before air exits the registers. By slowly ramping up the motor, the heat pump and the electric heat strips can “pre-heat” to avoid a drafty feeling in the winter.

Temperature swing comparison

Healthy

Helping everyone breathe easier

Featuring a factory-installed MERV 16 filtration system, the CBX40UHV provides more effective filtration for ideal air quality and comfort. This extremely compact air handler is designed with high-efficiency filtration in mind to provide an optimum home environment.
