Lochinvar & A.O. Smith 100110799 Damper Drive 321894-709 Electrical Isolation: Efficiently switches high-current

Electrical Isolation: Efficiently switches high-current fan loads using a low-voltage 24V control signal

The module operates on a standard 24V AC 50/60 Hz input and requires a transformer with at least a 20 VA rating

the ZF09K4E-TF5-931 utilizes liquid injection technology to manage discharge temperatures effectively

Minimal Maintenance: The free-floating lever mechanism reduces friction points

the motor maintains a consistent torque profile while adjusting airflow to match the modulated burner firing rate
