International Environmental 70021671 Motor R-410A as well as F300 modelsThe International Environmental 70021671 is a direct replacement 1 20 HP fan coil motor designed for high static and standard airflow applications across IEC hospitality and commercial terminal units. This 115V single phase motor utilizes Permanent Split Capacitor (PSC) technology for stable performance and consistent torque under load. Operating at a nominal 1050 RPM, it maintains the necessary static pressure for chilled water and DX systems. The
