Frequently Asked Questions (FAQ)
Q1: What is the exact filtration efficiency of this 5 micron nominal cartridge?
A: The nominal rating of 5 micron means it can remove approximately 99% of particles larger than 5 µm under standard test conditions. Actual efficiency may vary depending on fluid properties and flow rate. For absolute ratings, we recommend our sintered metal fiber series.
Q2: Can this filter be cleaned and reused?
A: Yes, the sintered metal structure is robust and can be cleaned by backwashing, ultrasonic cleaning, or chemical washing. Proper cleaning can restore most of the original flow capacity, making it a cost-effective solution.
Q3: What is the maximum flow rate for a 10-inch cartridge with 1/4 NPT?
A: Flow rate depends on fluid viscosity, pressure drop, and temperature. For water at 20°C with 10 psi differential, typical flow rate is around 2–4 GPM (7.5–15 L/min). Contact us for a detailed calculation based on your process parameters.
Q4: Is this cartridge suitable for high-temperature steam filtration?
A: Yes, the 316L material can withstand continuous temperatures up to 250°C (482°F), making it suitable for steam sterilization or hot gas filtration. However, we recommend confirming the exact temperature and pressure conditions with our engineering team.
Q5: Do you offer other micron ratings besides 5 micron?
A: Absolutely. We can manufacture sintered powder metal cartridges with filtration ratings from 1 micron to 100 micron nominal. Please specify your requirement when placing an order.
Q6: What end cap options are available for the 1/4 NPT connection?
A: Standard end caps are 1/4" NPT female threads on both ends. We also offer one-end closed, both ends open, with or without gaskets, and other thread types (BSP, NPT, flanged) upon request.
Q7: How do I choose the correct length for my housing?
A: Measure the depth of your filter housing (from the base to the top) and subtract the clearance needed for the spring or compression mechanism. Standard lengths are 10", 20", 30", 40". Custom lengths are available with a minimum order quantity.
Q8: What is the typical lead time for this product?
A: For standard sizes (10" length, 5 micron, 1/4 NPT), lead time is 7–15 working days after payment confirmation. Custom orders may require 15–25 working days, depending on complexity and quantity.
