Abstract
A vacuum assist system and process for handling cutting fluid and chips collected from a series of machine tools includes a closed header pipe extending below a series of sumps associated with the machine tools, the sumps draining into the header pipe. The header pipe has a down leg extending vertically down to a filter tank which is opened periodically to drain the header pipe, developing a vacuum which assists the flow of liquid down the header pipe so as to insure a sufficient flow velocity in the header pipe to carry the collected chips out of the header pipe and into the filter tank with the cutting fluid.
