Rotary Vacuum Drum Filtration System
The Rotary Vacuum Drum Filtration System features a robust, permanently rotating cylinder constructed with Filtra-Systems' PermaFlow technology or wedge wire, serving as an effective filtration septum. This innovative system collects contaminants from fluids efficiently and operates with a fully automated cleaning cycle, providing an eco-friendly, maintenance-free solution
Description
The Perma-Flow is Filtra-Systems' advanced rotary indexing micro-screen vacuum filter, offering significant advantages for machining applications. It utilizes a strainer-type separation with a unique pressurized incremental backwash system and a scraper for positive cake removal and conveyance. Capable of fine filtration below ten microns, the Perma-Flow's modular design supports parallel operations for large systems and provides complete redundancy.

Operation
The PermaVac functions with a patented vacuum-placed drum in the main filter tank, forming a cake on the outer surface without conventional paper media. Upon reaching a predefined limit, it initiates a continuous self-cleaning cycle that keeps running as the machine operates. Heavy particulates are collected at the tank bottom and discharged through a single point for efficient removal.
Product Range
These drum screen filter units vary in size, offering 3.5 to 140 square feet of filter area per unit to match specific application needs.
