Frequently Asked Questions (FAQ)
Q1: What is the difference between Johnson screen and conventional wire mesh?
A: Johnson screen uses V-shaped wedge wire wound around support rods, creating continuous slots that are less prone to clogging and provide higher open area. It is more durable and suitable for high-flow applications.
Q2: Can I get a different slot size than 0.5mm?
A: Yes, we offer slot sizes from 0.1mm to 6mm. Please specify your required filtration precision.
Q3: What is the maximum pressure this filter can withstand?
A: It depends on the diameter and wall thickness. Typically, our filters can handle up to 10 bar (145 psi) for standard designs. For higher pressure, we recommend 316L or heavier gauge wires.
Q4: Are you able to produce filters with custom lengths or diameters?
A: Absolutely. We can manufacture any length up to 6 meters, and outer diameters from 25mm to 600mm. Custom end connections (thread, flange, cap) are also available.
Q5: What is the typical lead time for a 2m filter?
A: For standard sizes, lead time is about 7-15 working days. Custom orders may take 15-25 days depending on complexity.
Q6: Is the 304 stainless steel suitable for sea water?
A: 304 has good resistance to fresh water and mild chemicals, but for sea water or high chloride environments, we recommend 316L or duplex stainless steel.
Q7: How do I clean the filter to maintain performance?
A: Backwashing or high-pressure water flushing is effective. The V-shaped slot allows particles to be released easily. For stubborn deposits, chemical cleaning may be used.
Q8: Do you provide samples for testing?
A: Yes, we can provide small samples (e.g., 300mm length) at a reasonable cost. Contact our sales team for details.
