Frequently Asked Questions (FAQ)
-
Q: What is the typical lifespan of this filter cartridge?
A: Lifespan depends on operating conditions and contaminant load. Under normal pharmaceutical use with proper cleaning and sterilization, a 304SS bag filter can last 1–2 years before replacement is needed. Regular inspection is recommended. -
Q: Can this cartridge be used for steam sterilization (autoclaving)?
A: Yes, the 304SS material and sanitary design are compatible with steam sterilization at temperatures up to 134°C. We recommend confirming the specific sterilization cycle parameters with our technical team. -
Q: Is the 0.5 micron rating absolute or nominal?
A: It is an absolute rating, meaning the filter retains at least 99.9% of particles sized 0.5 micron and larger. This meets the standards for critical pharmaceutical filtration. -
Q: What connection types are available?
A: Standard options include tri-clamp (1.5″, 2″, 2.5″), sanitary flange, and threaded connections (NPT, BSP). Custom adapters can be provided upon request. -
Q: Do you provide certificates of material or compliance?
A: Yes, we can supply material certificates (MTC) and a certificate of compliance for each batch. Additional documentation such as surface finish reports or passivation certificates are available upon request. -
Q: Can I order a sample before bulk purchase?
A: Absolutely. We offer sample orders for evaluation. Please contact our sales team to discuss your specific requirements and shipping details. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the size and configuration. Typically, standard sizes have an MOQ of 10–20 pieces. Custom designs may have higher MOQ. Please inquire for exact numbers. -
Q: How does this cartridge compare to a pleated stainless steel filter?
A: Bag-type filters offer higher dirt-holding capacity and lower pressure drop for the same surface area, making them ideal for high-flow applications with moderate particle loads. Pleated filters provide more surface area but are less robust for heavy solids. Our bag-type design is optimized for pharmaceutical processes where frequent cleaning is required.
