| Filtration Area | 0.5 m² per 10-inch element (customizable) |
| Max Operating Temperature | 80°C (higher with special seals) |
| Max Operating Pressure | 0.6 MPa (at 20°C) |
| End Cap Options | DOE, 222, 226, 215, etc. |
| Seal Materials | Silicone, EPDM, Viton (FKM), Buna-N |
| Length Options | 10", 20", 30", 40" or custom |
Key Features & Benefits:
- High Filtration Efficiency: The 0.2 micron absolute rating ensures removal of bacteria and fine particles, meeting pharmaceutical sterility standards.
- Large Filtration Area: Pleated design increases surface area, allowing higher flow rates and longer service life between replacements.
- Corrosion Resistance: 304 stainless steel withstands aggressive chemicals and high-temperature cleaning (CIP/SIP) without degradation.
- Low Pressure Drop: Optimized pleat geometry minimizes resistance, reducing energy consumption and pump load.
- Integrity Testable: Compatible with bubble point and diffusion tests for in-process validation.
- Easy Installation: Standard end cap designs fit most filter housings; quick-change options available.
- Customizable Options: Available in various lengths, seal materials, and micron ratings (0.1–50 μm) to suit specific process requirements.
Applications in Pharmaceutical Industry:
- Sterile liquid filtration (water for injection, buffers, media)
- Prefiltration and final filtration of active pharmaceutical ingredients (APIs)
- Biotech processing (cell culture, fermentation)
- Vaccine and biologic production
- Clean-in-place (CIP) and steam-in-place (SIP) compatible

Frequently Asked Questions
Q1: What is the difference between 0.2 micron and 0.45 micron filters?
A: A 0.2 micron filter is considered a sterilizing grade filter, capable of retaining bacteria such as Brevundimonas diminuta. A 0.45 micron filter is used for finer clarification but is not considered sterilizing. For pharmaceutical sterile applications, 0.2 micron is the standard.
Q2: Can this filter element be steam sterilized?
A: Yes, the 304 SS pleated filter element can withstand steam sterilization (SIP) at temperatures up to 135°C if proper seals are selected. We recommend silicone or EPDM seals for high-temperature service. Please confirm your exact sterilization parameters for a tailored solution.
Q3: What end cap configurations are available?
A: We offer DOE (double open end), 222, 226, 215, and other custom end caps. Please specify your housing type so we can match the correct configuration.
Q4: Do you provide samples for testing?
A: Yes, we can provide sample units for evaluation. Please contact us with your requirements, and we will arrange shipment. Sample costs may be charged but are refundable upon bulk order.
Q5: What is the typical lifespan of this filter element?
A: Lifespan depends on the feed quality, operating conditions, and cleaning frequency. Under normal pharmaceutical water applications, the element can last several months to a year. The large filtration area helps extend service life. Periodic cleaning (CIP) can restore performance.
Q6: Are these filters compatible with aggressive solvents?
A: The 304 stainless steel is resistant to many aqueous solutions, alcohols, and mild acids. For strong solvents like ketones or chlorinated hydrocarbons, we recommend 316L SS or special seals. Please consult our technical team for compatibility.
Q7: What certificates do you have for these filters?
A: Our products are manufactured under strict quality control. We can provide material certificates (MTC) and performance test reports upon request. We hold internal quality system standards but do not have third-party certifications like ISO or CE unless specifically requested. Please contact us for details.
Q8: How do I choose the correct length and sealing material?
A: The length depends on your filter housing. Common lengths are 10", 20", 30", and 40". For seal material, consider the fluid temperature and chemical compatibility. Silicone is suitable for general use, EPDM for hot water, and Viton for aggressive chemicals. We can help you select the best option.
