Frequently Asked Questions
Q1: What is the difference between a candle filter element skeleton and a standard filter cartridge?
A: The skeleton serves as a supportive core inside a pleated filter cartridge. It prevents the filter media from collapsing under pressure, while the filter media itself captures particles. The skeleton is typically made of stainless steel for durability, whereas the cartridge may be single-use.
Q2: Can this skeleton be used for both liquid and gas filtration?
A: Yes, it is suitable for both. However, the specific mesh or perforation design may need to be adjusted based on the fluid viscosity and pressure drop requirements. Please provide your working conditions for customization.
Q3: What are the common end cap options available?
A: Standard end caps include flat (both ends open), one open/one closed, or with threaded connectors. We can also produce custom ends (e.g., bayonet, flange) upon request.
Q4: Is the 304 stainless steel suitable for food or pharmaceutical applications?
A: Yes, 304 stainless steel is widely used in food processing and pharmaceutical industries due to its hygienic properties. If stricter requirements exist (e.g., FDA, 3-A), we can supply 316L or offer additional surface polishing and passivation.
Q5: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 100 pieces for standard sizes. Customized skeletons may require a higher MOQ. Please contact our sales team for exact quantities.
Q6: How do you ensure the quality of the skeleton?
A: We conduct incoming material inspection, in-process checks, and final dimensional and visual inspection. Each batch is tested for pressure resistance and corrosion resistance (salt spray test upon request).
Q7: Can you provide samples before bulk order?
A: Yes, we offer samples for evaluation. The sample cost and shipping charges are negotiable, and we will deduct the sample cost from the bulk order if applicable.
Q8: What is the typical lead time for production?
A: For standard 20-inch skeletons, lead time is 7–15 days after order confirmation. Customized orders may take 15–25 days, depending on complexity.
