For heavy-duty service, involving the suction of big quantities of dust and potential clogging issues on the vacuum unit’s filter, it is recommendable to use pre-separator.
Our pre-separator has an interior cyclone device. When the air mixed with dust comes into the separator, it forms swirling motion. Due to gravity, coarse dust will fall from the separator and fine dust will gather and go with the airflow into the vacuum, thus it can improve the dust collection efficiency.
