Products Description
Need a sanitary in-line filter for continuous particulate removal in your hygienic process line?
Guanjiang's Sanitary Pipeline Filter is a specialized filtration device installed in process pipeline systems within industries with stringent hygiene requirements — food, pharmaceuticals, and bioengineering. Designed for continuous removal of particulate contaminants and microorganisms from fluids, it features a 304/316L stainless steel housing, quick-release clamps, and precision filter screen (woven wire mesh or sintered mesh). With no dead legs and easy drainage, it fully supports CIP (Clean-in-Place) and SIP (Steam-in-Place) cleaning and sterilization — meeting cGMP, FDA, EHEDG, and 3-A sanitary standards.
Key Advantages
Superior Sanitary Design
Internally mirror polished (Ra ≤ 0.8 μm) prevents microbial retention. Quick-release clamp connections eliminate dead legs. Fully compliant with cGMP, FDA, EHEDG, and 3-A standards.
High-Efficiency Filtration
Precision filter screen (woven mesh or sintered) provides microns to hundreds of microns filtration. Large filtration area offers high dirt-holding capacity — low pressure drop minimizes system impact.
Fast Maintenance
Quick-open structure allows tool-free access for screen replacement. Vent and drain ports facilitate system venting and cleaning. Compact design with flexible installation.
Corrosion Resistant
High-quality 304/316L stainless steel ensures strong corrosion resistance. Robust design withstands high process pressures and temperature fluctuations. High-quality seals ensure leak-free performance.
Multiple Connection Standards
Tri-Clamp / SMS / DIN / ISO / RJT — seamless integration into existing sanitary piping.
CIP/SIP Compatible
Optimized internal structure — no dead legs, easy drainage. Fully supports in-place cleaning and sterilization.
Flexible Installation
Horizontal or vertical orientation — compact design saves valuable space.

Filter Screen Selection Guide:
Woven wire mesh: General purpose, good flow characteristics, easy to clean. Available in mesh sizes from 20 to 500 mesh (840μm to 25μm).
Sintered mesh: Higher mechanical strength, uniform pore distribution, withstands backflushing. Suitable for high-purity and high-pressure applications.
Multi-layer sintered mesh: Provides depth filtration, high dirt-holding capacity. Ideal for critical pharmaceutical applications.
Material: SS304 / SS316L — select based on fluid compatibility and regulatory requirements.
Applications
| Industry | Typical Applications | |
|---|---|---|
| Pharmaceutical | Process water, pure steam, compressed air, pharmaceutical liquids, API intermediates | |
| Food & Beverage | Final product filtration, CIP return water, ingredient filtration, process gas, beverage polishing | |
| Dairy Industry | Milk, yogurt, whey, cream, and various dairy product in-line filtration | |
| Cosmetics | Raw material filtration for essences, emulsions, creams, lotions, and gel products |
Frequently Asked Questions
Q1: What is the difference between a sanitary pipeline filter and a standard Y-strainer?
A: Sanitary pipeline filters are designed with no dead legs, electropolished surfaces (Ra≤0.8μm), and quick-release clamps — making them fully CIP/SIP compatible and compliant with cGMP/FDA/EHEDG standards. Standard Y-strainers have threaded or flanged connections, internal cavities, and rougher surfaces that can trap product and bacteria — not suitable for hygienic applications.
Q2: What filtration rating should I choose?
A: 1-10 microns: Fine filtration for pharmaceutical liquids, pure water, sterile applications (use sintered mesh). 10-50 microns: General process filtration for food/dairy products. 50-200 microns: Coarse filtration for CIP return, ingredient protection. 200-500 microns: Primary protection for pumps and valves. Contact us with your particle size specification for a recommendation.
Q3: How do you clean the filter element?
A: The housing and screen are CIP compatible — no disassembly required for standard cleaning cycles. For complete removal of captured particles: remove the screen (tool-free via quick-open clamp), rinse or brush the screen, and reinstall. For sintered mesh screens, backflushing or ultrasonic cleaning is recommended. Always follow your facility's cleaning validation protocol.
Q4: Can the filter be used for steam or high-temperature applications?
A: Yes. The 316L stainless steel housing withstands high temperatures. With PTFE seals, the filter is suitable for SIP (Steam-in-Place) sterilization up to 150°C. For pure steam applications, specify high-temperature seals when ordering.
Q5: What documentation is provided for pharmaceutical validation?
A: We provide mill certificates (EN 10204 3.1) with full material traceability, surface finish test reports (Ra measurements), seal material certificates (FDA compliance), and dimensional inspection reports. For critical applications, passivation certificates and weld logs are available upon request.
