Frequently Asked Questions (FAQ)
Q1: What is the primary function of this candle filter element skeleton?
A: This skeleton acts as a rigid support core for outer filter media (such as wound yarn, pleated paper, or melt-blown fabric). It maintains the cartridge shape, prevents media collapse, and allows high flow rates during pre-filtration.
Q2: Can this skeleton be used with existing filter housings?
A: Yes, the 50mm OD and 500mm length are standard dimensions. However, end cap configurations (flat, spear, threaded, etc.) can be customized to match your housing. Please provide your housing specifications for a perfect fit.
Q3: Is 304 stainless steel suitable for seawater or chlorine environments?
A: 304 SS offers good corrosion resistance in freshwater and mild chemical environments. For highly corrosive media like seawater or high chlorine, we recommend 316L stainless steel – which is available upon request.
Q4: What is the typical open area percentage of the perforated skeleton?
A: The open area depends on the perforation pattern (hole size and spacing). Typical values range from 30% to 50%. We can adjust the pattern to balance strength and flow. Contact us with your flow rate requirements.
Q5: What is the maximum pressure drop this skeleton can withstand?
A: The skeleton alone can withstand differential pressures of up to 5 bar (72 psi) without deformation, depending on wall thickness. The actual limit is influenced by the outer media and end cap design. We recommend testing within your system.
Q6: Do you offer custom lengths or diameters?
A: Yes, we can produce skeletons in various lengths (e.g., 250mm, 750mm, 1000mm) and diameters (e.g., 30mm, 60mm, 100mm). Minimum order quantities may apply for non-standard sizes. Contact us for a quote.
Q7: How is the skeleton surface finished? Is there a risk of contamination?
A: Standard finish is bright annealed, which is clean and free of burrs. For food or pharmaceutical applications, we can provide electropolished or passivated surfaces to reduce particle shedding. Please specify your cleanliness requirements.
Q8: What is the lead time for a standard order?
A: For standard 50x500mm 304 SS skeletons, production lead time is typically 10–15 working days after order confirmation. For large quantities or custom specifications, allow 15–25 working days. We also offer expedited shipping options.
