## PROPOSAL FOR VOTE: This rulemaking will explicitly exclude the following types of fans: cross flow fans, safety fans (including induced flow and jet fans), and circulating fans. Other exclusions may be added in the future. Vote results :2 

# Embedded fans

• Embedded fans

– Assembled by OEMs , designed specifically for use in HVAC equipment and are not distributed in commerce as stand alone equipment.

– Purchased by OEMs , and may or may not be also distributed in commerce as a stand alone fan

.

– Some embedded fans are used in already regulated equipment.



# • How does the working group want to address these fans?

– Some cannot be tested outside the equipment

– Some are incorporated in covered equipment with a metric that already captures fan energy use,

– Some are incorporated in equipment that do not represent large savings potential, etc.
