The RRFAN100A is a compatible infrared remote control designed as a substitute for the Lasko 2033666D remote. This model operates the same tower fan functions as the original, allowing you to adjust fan speed, oscillation, and timer settings from a distance. The RRFAN100A uses standard infrared technology to communicate with compatible Lasko tower fan models, providing convenient wireless control without requiring a direct line of sight in most cases. If your original remote is lost or damaged, the RRFAN100A offers a reliable replacement option for restoring full remote functionality to your tower fan.
