Frequently Asked Questions (FAQ)
Q1: What is the typical lifespan of this filter bag in oil filtration?
A: Lifespan depends on the oil contamination level and flow rate. Under normal conditions (e.g., hydraulic oil), the bag can last 300–500 hours before needing replacement. For heavily contaminated oil, more frequent changes may be required.
Q2: Can this filter bag be used for water filtration as well?
A: While designed for oil, the bag can be used for water filtration if the temperature and pressure are within limits. However, for water applications, we recommend using a different media (e.g., polypropylene felt) to avoid hydrolysis. Please consult our sales team for guidance.
Q3: Are there different ring materials available?
A: Yes, we offer stainless steel rings in 304 and 316 grades. 316L is also available upon request for highly corrosive environments. The standard is 304 stainless steel.
Q4: How do I ensure the correct size for my filter housing?
A: We provide standard sizes #1 through #5, and custom sizes are available. Please provide your housing dimensions (diameter and length) or the bag number you currently use, and we can match it precisely.
Q5: What is the maximum flow rate for this 10 micron filter bag?
A: Flow rate depends on bag size and viscosity. For a standard #2 bag (7" x 32") with low-viscosity oil, the recommended flow is up to 40 m³/h. For viscous oils, flow rate should be reduced to maintain efficiency. We can provide detailed calculations based on your application.
Q6: Do you provide certificates of quality or material test reports?
A: Yes, we can provide a material certificate and quality inspection report with each shipment. If you require a specific third-party inspection, we can arrange it at an additional cost.
Q7: Is the needle felt media washable and reusable?
A: These bags are typically disposable. However, some customers clean them with compressed air or gentle washing for light-duty applications. Reuse may reduce filtration efficiency. For critical applications, we recommend using a new bag each time.
Q8: What is the lead time for bulk orders?
A: For standard sizes and materials, lead time is 15–20 working days after order confirmation. Custom orders may take 25–30 days. We can expedite for urgent projects upon request.
