STAR Filter

The HydroFlow STAR FilterĀ® product is an innovation in vacuum element filtration.

The design is simple, rugged, and incorporates features to overcome the common problems of rotating vacuum drum filters.



The STAR FILTER® Product uses one the most proven technologies available to the machine tool industry and offers big advantages over every other available technology including: Vacuum Drum Filters, Pressures Precoat and Flat Bed Pressure Filter.
 
The HydroFlow Star Filter® product is an innovation in vacuum element filtration. The design is simple, rugged, and incorporates features to overcome the common problems of rotating vacuum drum filters. Each STAR ELEMENT is precision built, and totally interchangeable. The vertical angle of each fuse-bonded. MICROSCREEN panel provides a vertical drop for the dislodged filter cake, providing gentle yet thorough settling of the vacuum compressed filter cake. Each STAR ELEMENT can be removed for inspection and reinstalled into the STAR SEAL without concern for misalignment or proper sealing.

STAR FILTER® products eliminate problems associated with drum filters and deliver higher performance with HydroFlow’s patented STAR ELEMENT.

Double layer weave synthetic media, stainless steel wedgewire or patented fuse-bonded stainless steel microscreen filter panels are constructed to meet specific customer requirements based on application and provide reliable, maintenance-free, effective filtration.

The element’s star shape and the filter panel’s compact, rectangular design maintains structural integrity after removal from the filter. With the end caps removed, cleaning on both sides of the filter panels is simple, unlike the circular construction used in drum filters.

The STAR ELEMENT is designed with an internal support structure that allows continuous efficient removal of entrained air.
 

FeaturesPositive Cake
Removal
Clean fluid “backflow” eliminates the need for large volumes of air (used in Pressure Filters) or Doctor Blades (used in Drum Filters). Doctor Blades can force solids through and into the clean stream and also lodge dirt into the screen reducing the open area for filtration.
The STAR SEAL
an Element
Connection that Works
The STAR SEAL ensures trouble free, effective sealing using a patented wet seal arrangement with high tolerance machined surfaces. The positive seal between the STAR FILTER element and the suction manifold eliminates contamination by-pass, common in other designs.Fully Automatic OperationEliminates the complex hydraulic or air closures systems required to seal pressure filters.
Element
Isolation and
Interchangeability
Double layer weave synthetic media, wedgewire or Precoated Microscreen panels provide filtration as low as one micron and eliminate the difficult handling and disposal of bulky roll mediaConveyor DragoutA heavy duty conveyor dragout system that can operate continuously or can be set to index removes the solids from the filter
Automatic
Precoat Cycle
Ensures that there is no migration of dirty fluid (leaking past seal due to misalignment of the module, as in the case with O-ring connections).Vacuum

Filtration
Eliminates the complex hydraulic or air closures systems required to seal pressure filters.
Patented
Microscreen
Panels
A permanent filter septum and unlike drums or tubes, the panels of Fuse Bonded Microscreen can be cleaned on both sides, eliminating the costly replacement of filter septums.Individual STAR
Element
Isolated with manual butterfly valves can easily be removed without draining the fluid from the system or laborious disassembly of pressure vessels.
