Introduction: Finding the Right Alternative for Industrial Filtration
Selecting the right depth filter sheet is an important decision for manufacturers in the food, beverage, pharmaceutical, chemical, and edible oil industries. The filtration media you choose can affect product clarity, processing efficiency, operating costs, and the consistency of your final product.
Established filtration brands such as Pall Seitz, Eaton BECO, and Parker offer depth filtration products for a variety of industrial applications. Each manufacturer has its own product portfolio, material formulations, technical specifications, and application recommendations.
However, established brands are not the only consideration when evaluating filtration solutions. Purchasing teams and process engineers may also explore alternative filter sheet manufacturers to improve supply flexibility, compare costs, obtain customized specifications, or develop additional sourcing options.
Great Wall Filtration, manufactured by Shenyang Great Wall Filtration Co., LTD, provides filtration products for industrial liquid processing. Its product portfolio includes depth filter sheets, activated carbon filter sheets, filter cartridges, filter membrane stacks, and filtration equipment.
This guide explains the main factors to consider when comparing Great Wall filter sheets with products from Pall Seitz, Eaton BECO, and Parker, helping industrial buyers make more informed sourcing decisions.

Understanding the Major Depth Filter Sheet Brands
Before comparing products, it is important to understand what each manufacturer offers and how its filtration media fits different production requirements.
Pall Seitz Filter Sheets
Pall Seitz is an established name in depth filtration, particularly in food and beverage processing. Its filter sheets are designed for applications involving clarification, fine filtration, particle retention, and certain microbial reduction requirements.
Depending on the product grade, these media can be used in beer, wine, spirits, dairy products, bottled water, and food ingredients.
Pall describes its depth filtration technology as combining surface filtration, depth filtration, and adsorption mechanisms. These mechanisms help capture particles and colloidal contaminants throughout the filtration medium.
Eaton BECO Filter Sheets
Eaton offers several depth filtration product families, including BECO and BECOPAD. These products address different clarification and filtration requirements across beverage production, food processing, cosmetics, pharmaceuticals, and biotechnology.
For example, BECO Standard filter sheets are available in multiple nominal retention grades, while BECOPAD products focus on high-purity cellulose media.
When evaluating Eaton products, buyers should distinguish between individual product families rather than treating all BECO filter sheets as interchangeable.
Parker Depth Filter Sheets
Parker offers DEPTH-CLEAR filter sheets for a range of processing applications. Different series are designed for particular requirements, including pharmaceutical processing, low-extractable applications, high-strength media, and general-purpose filtration.
Material composition, mechanical strength, extractables, and the intended process environment are important considerations when evaluating a Parker product.
Great Wall Filter Sheets
Great Wall Filtration focuses on industrial filtration products and application-specific supply requirements. Its product range includes depth filter sheets for liquid clarification, activated carbon filter sheets for adsorption-related applications, and complementary filtration products.
For distributors, filtration equipment suppliers, and industrial manufacturers, working directly with a manufacturer can provide an opportunity to discuss product specifications, application requirements, packaging, and sourcing arrangements.
Rather than assuming that a Great Wall product is automatically equivalent to a particular competitor grade, buyers should compare technical data and verify performance under their actual operating conditions.

Great Wall vs. Pall, Eaton BECO, and Parker: What Should Buyers Compare?
A meaningful comparison should focus on the filtration requirements of the application rather than brand names alone.
| Evaluation factor | What buyers should examine |
| Filtration grade | Nominal retention rating and validated performance |
| Filter media | Cellulose, mineral components, activated carbon, or other specified materials |
| Dirt-holding capacity | Ability to handle the contaminant load before replacement |
| Flow performance | Throughput under comparable operating conditions |
| Mechanical strength | Wet strength and compatibility with the filter press |
| Product compatibility | Effects on flavor, color, purity, or chemical composition |
| Regulatory requirements | Applicable food-contact or industry-specific documentation |
| Commercial supply | Minimum order quantities, lead times, packaging, and customization |
These factors help purchasing teams compare products on a consistent basis.
For example, a filter sheet with a finer nominal retention rating may be appropriate for one process but unsuitable for another if it causes excessive pressure buildup or requires frequent replacement.
Likewise, a sheet with a high flow rate in a water test may not deliver the same performance when filtering a viscous syrup or a liquid with a high suspended-solids concentration.
The most suitable product is the one that meets the required filtration outcome while maintaining acceptable operating efficiency and product quality.

Can Great Wall Filter Sheets Replace Pall Seitz, Eaton BECO, or Parker Products?
One of the most important questions for industrial buyers is whether an alternative filter sheet can be used in an existing filtration process.
The answer depends on the original product grade, process conditions, equipment configuration, and required filtration results.
A replacement should not be selected based on thickness, color, dimensions, or nominal micron rating alone.
Check the filtration performance
First, identify the purpose of the existing filter sheet.
Is it intended for coarse filtration, clarification, fine filtration, colloid reduction, or a specific adsorption function?
The replacement must address the same process objective. A general-purpose clarification sheet, for example, should not automatically be substituted for a grade designed for a more demanding retention requirement.
Compare the material composition
Different filter sheets may contain different combinations of cellulose fibers, mineral filter aids, and other functional materials.
These differences can affect filtration behavior, extractables, adsorption characteristics, and compatibility with the liquid being processed.
For sensitive food, pharmaceutical, and biotechnology applications, material documentation and suitability assessments are particularly important.
Verify equipment compatibility
Confirm the sheet dimensions, thickness, configuration, and fit with the existing plate-and-frame filter press.
Incorrect dimensions or inadequate wet strength can result in poor sealing, leakage, handling difficulties, or other operating problems.
Conduct a controlled trial
Where possible, test the proposed replacement using the actual liquid or a representative process stream.
Measure relevant parameters such as:
- Initial and average filtration flow rate.
- Operating pressure and pressure increase over time.
- Total volume processed per sheet or filtration cycle.
- Filtrate clarity and other product-quality indicators.
- Product loss, handling requirements, and replacement frequency.
A controlled trial provides a more reliable basis for deciding whether an alternative is suitable than a comparison of catalogue specifications alone.
Great Wall Filtration can be contacted to discuss the original filter sheet specification and identify candidate products for technical evaluation.

Applications of Great Wall Depth Filter Sheets
Different industries have different filtration challenges. Selecting the correct media begins with understanding the liquid, the contaminants, and the desired result.
Edible Oil Filtration
Edible oil manufacturers may need to remove suspended particles, residual processing materials, or other impurities during oil production and polishing.
Filter sheet selection depends on the oil type, temperature, viscosity, contaminant load, and desired final quality.
Great Wall offers filtration products for industrial liquid processing, including applications involving edible oils. Buyers should confirm the suitability of the specific grade for their oil and operating conditions.
Food and Beverage Processing
Food and beverage producers may require filtration for syrups, sugar solutions, fruit juices, tea extracts, and other liquid ingredients.
The key objectives can include removing suspended solids, improving clarity, and protecting downstream processing equipment.
The appropriate filter sheet depends on the liquid composition and the required degree of clarification.
Gelatin and Collagen Processing
Gelatin and collagen solutions can present filtration challenges because of their viscosity, protein content, and sensitivity to processing conditions.
A suitable filtration strategy may involve multiple stages, with different grades used for initial clarification and subsequent polishing.
Process temperature, viscosity, solids loading, and acceptable product loss should all be considered when selecting filter media.
Pharmaceutical and Specialty Chemical Processing
These applications may impose additional requirements for material compatibility, extractables, traceability, cleanliness, and documentation.
Buyers should verify that the specific filter sheet and its supporting documentation meet the requirements of their intended process.
No product should be assumed suitable for a regulated application without an appropriate technical and regulatory review.
