Frequently Asked Questions (FAQ)
Q1: What is the exact slot opening tolerance?
A: Our standard tolerance for the 0.2mm slot opening is ±0.05mm, ensuring consistent filtration performance. Tighter tolerances are available upon request.
Q2: Can this filter be used for sand and gravel removal in well water?
A: Yes, the 0.2mm slot is effective for filtering fine sand and silt particles. It is commonly used in well screens and water intake systems.
Q3: How do I clean the filter?
A: The wedge wire design allows for easy backwashing with water or air. For stubborn deposits, chemical cleaning or mechanical brushing can be used. The filter is designed to withstand repeated cleaning cycles.
Q4: What is the maximum pressure rating?
A: The pressure rating depends on the diameter and length. For a typical 100mm diameter filter, the maximum working pressure is around 10 bar (145 psi). Please provide your specific requirements for a detailed calculation.
Q5: Do you offer custom lengths and diameters?
A: Absolutely. We can manufacture filters in any length up to 6 meters and diameters from 25mm to 300mm. Custom dimensions are welcome – just provide your drawing or specifications.
Q6: What is the typical lead time?
A: For standard sizes, lead time is 15-20 days after order confirmation. Custom orders may take 20-30 days depending on complexity. We can also arrange express delivery for urgent needs.
Q7: Can you provide samples before bulk order?
A: Yes, we offer samples (usually 1-2 pieces) for quality evaluation. The sample cost is negotiable, and we can refund it upon bulk order placement.
Q8: Is this filter suitable for seawater desalination?
A: Because 304 stainless steel has good corrosion resistance, it is suitable for freshwater and mildly corrosive environments. For seawater (high chloride), we recommend 316L stainless steel as an alternative (available upon request).
