Abstract

The present invention provides a liquid filtration device with internal flow paths that facilitate the purging of air bubbles from the device. The device includes internal channels that collect bubbles from fluid entering the filtration device and more efficiently direct fluid to sweep bubbles from the device during operation. The present invention also provides for an automatic means to minimize fluid loss during a vent process.
