Complete Filtration Solutions

Protecting Product Quality, Equipment and Process Performance

Filtration is a critical part of many industrial and hygienic process systems. The correct filtration method depends on what must be removed, retained or separated, as well as the process medium, operating conditions, hygienic requirements and installed equipment.

LGN Group supports filtration requirements across food, dairy, beverage, pharmaceutical, cosmetics, water and industrial processing applications. Depending on the process, the solution may involve a process filter, membrane system, stainless steel strainer, cartridge or filter housing.

This main Filters & Strainers page is designed as an overview and navigation hub. Detailed technical information for Donaldson Process Filters, Membrane Filters and Strainers will be covered in their dedicated product pages.

For replacement projects, available OEM information such as model numbers, part numbers, housing references, element codes, drawings and equipment photos can be used to support technical identification and sourcing.

03 Mechanical Straining Future Page: Strainers

Industrial Strainers

Mechanical straining solutions used to retain larger particles and debris before they can reach downstream pumps, valves, heat exchangers and other process equipment.

Typical Applications

Process piping, utility lines, equipment protection, transfer systems, liquid circulation and industrial processing applications where mechanical screening is required.

OEM Replacement Support Existing strainer type, connection information, screen details, body configuration and equipment references can be reviewed for replacement enquiries.

04 Housings

Filter Housings

Filter housings provide the mechanical structure and process connection required to install cartridges, elements or other filtration media within hygienic and industrial process lines.

Typical Applications

Product filtration, utility filtration, process water, sanitary liquid lines, industrial systems and installations requiring replaceable filter media.

OEM Replacement Support Housing model, connection details, element type, dimensional data and original manufacturer references can be used to support replacement identification.

05 Replacement Elements

Filter Elements & Cartridges

Replacement filtration elements and cartridges used within process housings to perform the actual filtration or separation function specified for the installed system.

Typical Applications

OEM Replacement Support Part numbers, exploded drawings, nameplate information and existing equipment references can be used to support accurate sourcing of filtration spare parts.

Technical Selection

Which Filtration Route Fits the Application?

Filtration equipment should be selected according to the actual process objective rather than by product appearance alone. Particle size, process medium, installed equipment, hygienic requirements and the required separation mechanism all influence the appropriate solution.

Process Filtration

Filter Housings & Replaceable Elements

Suitable where contamination must be retained by a replaceable filter element or cartridge installed inside a dedicated process housing.

Typical question: Do we need controlled product or utility filtration using a defined replacement element?

Membrane Technology

Selective Separation

Used where the process requires separation or retention beyond ordinary screening or cartridge filtration and membrane technology forms part of the process itself.

Typical question: Is the objective clarification, concentration, fractionation or another membrane-based separation duty?

Mechanical Straining

Pipeline & Equipment Protection

Appropriate where larger particles, debris or foreign material must be intercepted mechanically before reaching downstream process equipment.

Typical question: Is the main purpose to protect pumps, valves, heat exchangers or other equipment from larger solids?

Information Required for Technical Selection

The following information helps determine the appropriate filtration technology and supports accurate selection for both new installations and OEM replacement enquiries.

Selection Checklist

01 Process Objective

Identify whether the requirement is contamination removal, equipment protection, clarification, separation, concentration or another filtration duty.

02 Process Medium

Confirm the product, liquid, utility or service medium passing through the filtration equipment.

03 Material to Be Removed

Define the type of contamination, particles or material that should be retained, separated or removed from the process stream.

04 Installed Equipment

Existing housing models, membrane systems, strainers, connections and element references should be identified for replacement projects.

05 Hygienic & Process Requirements

Product-contact design, cleanability, compatibility and process environment should be considered where sanitary service is required.

06 Installation & Maintenance

Orientation, available space, process connections, element replacement, cleaning access and long-term maintenance requirements should be reviewed.
