Upgrade Your Motor System — 40+5μF Dual-Value Run Capacitor
If your air conditioner, refrigerator, or pressure washer experiences difficulty starting, unstable operation, unusual noises, or overheating, it's likely due to degraded run capacitor capacity
40/5 μF 370/450V Dual Run Capacitor is an essential component for air conditioner compressors, fan motors, and electric high-voltage cleaning machines
It continuously supports the phase shift between motor windings, improving startup torque, reducing vibration, and maintaining steady performance even under fluctuating loads
By optimizing the magnetic field phase, capacitor enhances power factor and minimizes reactive losses — improving efficiency and extending the life of your motor system
Built with high-quality metal casing and durable dielectric materials, it resists heat, humidity, and mechanical stress, ensuring long-term reliability
Its standard connection layout (Herm, Fan, C) allows for quick installation and direct replacement of most 40/5uF capacitor models found in residential, commercial, and industrial applications
Compatible with most 40/5 μF (MFD) capacitor models, including 97F9838, Z97F938, 97F9838BZ3, 12786, RC0108, 97F9849, C3DR405, Z97F9848BZ2, P291-4054RS, C3405R, HCKS400D050R440Z, P291-4053RS, TRCFD405, P-CAP-40/5/440R, HC98JA041, HC98CA040, HC98CA041, HC93CZ035
Installation Tips: Please operate with power off and confirm that parameters of apacitors are consistent before replacing
Whether you're maintaining an HVAC unit, pressure washer, or compressor, capacitor delivers stable performance, reliable start-up, and operation for years to come
