Capacitor, Dual Run, 70/10 uF, 440 Volt VAC, Round

Lennox by Mars® 29W09 Dual Run Capacitor – 70/10 MFD, 440V, Round The Lennox 29W09 is a dual-section run capacitor designed for use in HVAC systems requiring support for both compressor and condenser fan motors. With a capacitance rating of 70/10 microfarads and a voltage rating of 440V AC, it provides continuous-duty operation for permanent split capacitor (PSC) motor circuits. Manufactured with metallized polypropylene film and enclosed in an aluminum canister, the 29W09 includes an internal pressure-sensitive interrupter to protect against overpressure conditions. It is configured with standard ¼" male quick-connect terminals for compatibility with OEM systems and field-replacement applications. Technical Specifications: OEM Part Number: 29W09 Capacitance: 70/10 MFD (μF) Voltage Rating: 440V AC Configuration: Dual run Shape: Round Terminals: ¼" male quick-connect Dielectric: Metallized polypropylene film Enclosure Material: Aluminum Protection: Pressure-sensitive internal interrupter Operating Temperature Range: -40°C to +70°C Compliance: UL 810 certified Application: Designed for use with Lennox HVAC systems and compatible PSC motor applications Application Overview: Supports dual motor operation—typically compressor and fan—within air conditioning and heat pump systems. Intended for use in Lennox-branded equipment or systems requiring a 70/10 MFD capacitor at 440V. Suitable for both residential and light commercial HVAC installations. Functions as a direct replacement for original capacitors with identical electrical and physical characteristics. Installation Considerations: Disconnect power and discharge the old capacitor before removal. Match capacitance and voltage ratings to original system requirements. Follow terminal markings (C, FAN, HERM) for correct wiring. Ensure capacitor is securely mounted and shielded from moisture and vibration. Installation should be completed by a qualified technician in compliance with local and national electrical codes. The 29W09 provides stable, long-life support for dual-motor HVAC configurations. Its high-voltage rating and OEM-quality construction make it a suitable option for servicing Lennox equipment in demanding operating environments.
