Sintered Metal Fibre Filter

Sintered Metal Fibre Filter Media

For Polymer Melts, Filament Spinning and Process Liquids

A Bonded, Porous Metal Network

Sheet Media | Pleated Elements | Leaf Disc Media

Technical Selection

Match the media family, retention requirement, flow resistance and support construction to the application. The supplied filter is defined by the agreed drawing and performance specification.

Construction and Family Selection

A Fibre Network with Space for Contaminants

In graded depth media, coarser inlet regions intercept larger contaminants while finer regions retain smaller material within the structure. Distributing retention through the depth helps use the available pore volume.

Listed sheet size: 1500 × 1180 mm. Protective mesh is offered on one or both sides.

Match the Construction

The diagram illustrates a graded medium. Confirm the actual layer sequence, flow direction, protective mesh and structural backing for the selected family.

A3 Polymerisation and Spinning

Multilayer Media for Pleated Filters

A3 is the broad pleatable family in the catalogue, covering polymerisation, spinning and process liquid applications.

* Test basis and specification requirements.

Specify the Finished Filter

Confirm the media thickness, steel grade, supporting layers and effective filtration area before choosing a finished candle or pack assembly. A media code alone does not define the complete filter.

Retention Requirement

Request the particle size, removal efficiency and test method associated with the selected model. The numerical prefix in a model name is not presented here as an absolute micron rating.

C4 and C3 Depth Filtration Media

Select for the Fluid and Mechanical Duty

C4 Compression Resistant Media

Multilayer, pleatable construction aimed at dirt capacity and compression resistance.

C3 Lower Viscosity Fluids

Multilayer, pleatable media for monomers, prepolymers and other lower viscosity fluids.

* Test basis and specification requirements. The catalogue lists 1700 Pa for both 20C3 and 25C3; confirm the selected grade before ordering.

Mechanical Duty

Bubble point pressure is a wetting test result. It is not the allowable operating pressure or the collapse differential pressure of the completed element.

D4 and E4 Disc and Pleated Media

Choose the Required Forming Behaviour

D4 High Strength Disc Media

Multilayer media for polymer leaf disc filtration; specified as non pleatable.

E4 Media for Pleating

Symmetrical multilayer construction developed for improved pleat formation.

* Test basis and specification requirements.

B3 and F3 Single Layer Media

Options for Different Service Priorities

B3 Low Contamination Liquids

Pleatable media for lower viscosity liquids such as hydraulic oil and fuel.

F3 Economical Media

Lightweight, pleatable construction positioned as an economical option.

* Test basis and specification requirements.

Understanding the Test Data

Compare Values on a Defined Test Basis

Air Permeability Test Basis

Air permeability is presented as catalogue reference data in L/(dm²·min), meaning litres per square decimetre per minute. The unit interpretation, test pressure and acceptance limits require confirmation with TSP before specification.

Specification of the Finished Filter

The page does not provide complete grade specific thicknesses, alloy specifications, retention efficiency curves or finished element pressure and temperature limits. Obtain these for the selected construction before approval.

From Media Data to Process Performance

Pressure loss depends on fluid viscosity, flow, filtration area and media resistance. Airflow figures cannot directly predict polymer melt pressure loss.

Use application specific flow data and include the support structure and element geometry in the review.

Controlled Comparison

Compare candidate media at the same fluid, temperature, throughput and required retention. Verify clean pressure loss and subsequent pressure rise in the actual supported element.

Application, Cleaning and Validation

Qualify the Media in the Operating Process

Cleaning and Reuse

Select the cleaning method for the deposit, alloy and assembled filter. Polymer filters may require thermal, chemical or ultrasonic treatment, followed by cleanliness and integrity assessment. Use a qualified procedure matched to the element.

Compare post cleaning flow and integrity results with a documented new element baseline. Integrity testing and particle removal efficiency measure different things; an acceptance method needs validation for the particular medium and element design.

Release for Reuse

Set approved acceptance limits, retain the element identification and cleaning history, and inspect the support structure, joints and sealing surfaces before returning the filter to service.
