DALON is a specialized manufacturer of sintered plastic and metal filtration components. With ISO 9001:2015-certified production processes, we ensure every filter disc meets stringent dimensional, flow, and durability requirements. We offer complete OEM customization, including micron grade, outer diameter, disc thickness, and fitment design to meet your exact assembly specifications.
Q1: What does a 20µm plastic disc filter remove?
It removes particles such as sand, scale, and suspended debris in air or water-based systems.
Q2: Is the filter chemically compatible with standard fluids?
Yes. PE is suitable for most neutral and mildly aggressive solutions. For strong acids or solvents, consider PVDF alternatives.
Q3: Can this filter be reused?
Yes. It is washable and durable. Rinse with water, soak in mild detergent, or use ultrasonic cleaning depending on the contamination.
Q4: Is this disc food-safe?
Yes. Sintered PE is food-grade and suitable for potable water and food-related applications.
Q5: Can DALON provide custom-sized filters?
Absolutely. We can tailor the disc diameter, thickness, and micron level to fit your housing or product requirements.
Q6: What industries use this disc filter?
Commonly used in irrigation systems, analytical instruments, air and gas handling modules, dosing and fluid delivery, and OEM water purification equipment.
