Airflow for an undercut door:
30" Door with .5" gap — 25 CFM
30" Door with 1" gap — 50 CFM
Example: If 177 CFM is being delivered to a room, using a 1" gap under the door and a 12 x 12
Return Air Pathway can relieve the pressure. (50 + 127 = 177 CFM)

Concept 3™ Motor
The Concept 3™ motor is a brushless, permanent magnet motor.
The Concept 3™ motor is a drop-in replacement for the common Permanent
Split Capacitor (PSC) motor that is used in most furnaces, air conditioners and
heat pump systems using a 24v thermostat.
Why the Concept 3™ motor is better than the standard PSC motor:
• Lower wattage use at any speed
• Realize immediate energy savings
• Built in intelligence for super
efficient operation in dry, humid
and mixed climates
• Wider range of speed settings
