Son equipos fundamentales y críticos para los procesos de reducción directa.

Su función es comprimir y favorecer la recirculación de la corriente de gas proveniente del reactor por el recuperador de calor y reformador para formar los gases reductores, ricos en hidrógeno y monóxido de carbono, que se utilizan para la reducción de mineral de hierro dentro del reactor y obtener la calidad de producto deseada.

Estos se encuentran instalados en las Plantas Briqueteras y de Reducción Directa pertenecientes al Sector Hierro Acero.
