What is the difference between Sintered Fiber Felt and Stainless Steel Wire Mesh filter cartridges?
The main difference lies in the filtration depth. Sintered Stainless Steel Fiber Felt (used in our SBF series) is a non-woven, porous depth media that offers significantly higher dirt holding capacity and better gel removal than surface-type Stainless Steel Wire Mesh. While wire mesh is good for simple sieving, sintered fiber felt is essential for filtering high-viscosity fluids and capturing deformable contaminants.
Why choose a Pleated Stainless Steel Filter over a Cylindrical one?
A Pleated Stainless Steel Filter Cartridge offers up to 3-4 times the filtration surface area of a standard cylindrical filter of the same dimension. This pleated structure significantly reduces the initial pressure drop and increases the total dirt holding capacity, allowing for longer service intervals and a smaller housing footprint.
Can the Stainless Steel Pleated Filter Cartridge be cleaned and reused?
Yes, one of the key advantages of our stainless steel cartridges is their cleanability. They can be regenerated using methods such as ultrasonic cleaning, chemical cleaning (acid/alkali bath), or high-temperature furnace cleaning. Depending on the contaminant type and cleaning method, they can be reused multiple times, significantly reducing long-term operational costs.
What is the temperature limit for these sintered stainless steel filters?
Our standard Stainless Steel Pleated Filter Cartridges can withstand continuous operating temperatures up to 480°C (896°F), making them ideal for extreme heat applications like steam filtration, hot gas filtration, and high-temperature polymer processing.
Is this filter cartridge suitable for high-viscosity fluids like Polymer Melts?
Absolutely. The SBF Series is specifically engineered for high-viscosity fluid filtration, including polymers, resins, and viscous syrups. The strong all-welded construction and sintered fiber media can withstand high differential pressures without collapsing or media migration.
Can this cartridge remove gels from liquid streams?
A: Yes. The tortuous path structure of the sintered metal fiber felt is highly effective at capturing shear-sensitive contaminants like gels and agglomerates that would typically pass through or deform on a standard wire mesh screen. This ensures superior quality in final products like optical films or high-grade fibers.
Do you offer replacements for Pall or Hydac stainless steel filters?
LOONG Filtration manufactures direct replacement stainless steel pleated cartridges for major brands like Pall, Hydac, and Parker. Our cartridges are dimensionally compatible (e.g., Code 222, 226, DOE) and meet or exceed the OEM performance specifications for filtration efficiency and dirt holding capacity.
What micron ratings are available for the SBF Series?
We offer a wide range of absolute micron ratings from 3 microns to 100 microns. The most popular ratings for polymer filtration are 5, 10, and 20 microns. Custom micron ratings can also be manufactured to meet specific industrial requirements.
How do you ensure the structural integrity of the cartridge under high pressure?
We use advanced vacuum sintering and plasma welding technologies. The end caps, inner core, and outer cage are fully welded to the pleated media pack (no adhesives are used). This zero-leakage construction ensures the cartridge maintains its integrity even under high differential pressures and aggressive chemical environments.
Are these filters compatible with aggressive chemicals?
Yes, typically constructed from 316L Stainless Steel, these cartridges offer excellent chemical compatibility (pH 1-14). They are resistant to acids, alkalis, and solvents, making them suitable for aggressive chemical processing, pharmaceutical, and petrochemical applications. We can also supply Hastelloy or Inconel for even more corrosive environments.
Can your filters handle high-temperature or corrosive environments?
Yes, we offer filter cartridges made from PTFE, PES, stainless steel, and other materials resistant to high temperatures, acids, alkalis, and aggressive chemicals.
What are the key factors in selecting the right filter cartridge?
Key factors include micron rating, flow rate, chemical compatibility, operating pressure, temperature, and the type of contaminants to be removed. Our engineers can help you choose the optimal filter element for your application.
