The Liebert CF91C-A00 is a cooling fan component engineered for integration within Liebert/Emerson thermal management systems. It facilitates efficient heat dissipation in air-cooled condensers and precision air conditioning units, maintaining optimal operating temperatures for sensitive electronic equipment and ensuring reliable performance of critical infrastructure.
Technical Specifications
Liebert fan motors associated with this component class operate as single-phase permanent split capacitor (PSC) motors or variable frequency drive (VFD) inverter duty motors. Fan blade diameter is typically 26 inches (660 mm) or less. Motor ratings include 208-230/460 V, 50/60 Hz, 3PH configurations, as well as 1/4 HP 208-230 V, 1PH options. Electronically commutated (EC) fan variants are available for enhanced efficiency.
Air-cooled condenser systems employing this fan component are rated for outdoor ambient operation from -20°F (-28.9°C) with optional low-ambient heater kits enabling year-round functionality across extreme temperature variations. Precision cooling applications require airflow volumes of 500–600 CFM per ton of cooling capacity.
– Key Features
• Continuous air-over motor operation
• Permanently sealed bearings
• Rain shield protection
• Single-phase PSC or three-phase VFD motor compatibility
• EC fan option for efficiency optimization
• Low-ambient operation capability down to -20°F (-28.9°C)
– Typical Applications
The CF91C-A00 serves as a core thermal management component in Liebert/Emerson air-cooled condenser units and precision environmental control systems for data centers, server rooms, and mission-critical electronic facilities.
– Compatibility & Integration
This cooling fan integrates into broader Liebert/Emerson thermal management solutions. System electrical supply configurations support 120 V, 200/208/230 V, and higher industrial voltage ratings at 50 Hz or 60 Hz operation. Condenser units require dedicated line voltage electrical supply independent of primary system circuits.
