Rotary Vacuum Drum Filtration System

The rotary vacuum drum filtration system is a permanent rotating cylinder that is constructed of Filtra Systems PermaFlow technology or wedge wire that acting as a filtration septum.

This rotating cylinder collects the contaminates from the fluid and quickly conveys them out during a fully automated cleaning cycle; all while offering a completely green and maintenance-free solution.

The Perma-Flow is the Filtra-Systems rotary indexing micro screen vacuum filter which offers a number of benefits in machining applications.  

The Perma-Flow offers strainer type separation with a unique pressurized incremental backwash system and scraper for positive cake removal and conveyance system.

Fine filtration of fewer than ten microns is a reality with the Perma-Flow rotary drum filter, and its modular design provides for parallel operation on large systems, or total spare capability.

The PermaVac operates with a patented vacuum placed drum in the main filter tank. This drum is designed to build up a cake on the external surface with no aid of conventional paper media. Once the operations reach a predesigned limit the system initiates a self-cleaning cycle that continuously runs while the machine is in operation. The heavy particulate falls from the filtration drum and is collected at the bottom of the filter tank where it is conveyed out of a single discharge point for easy collection and removal.
