Product Description

20µm Plastic Disc Filter – For Water, Air & Chemical Use

PLASTIC FILTER DISC 34.5X3 20MICRON Additional image 1

Plastic Disc Filter – 20µm Sintered PE Disc, 34.5×3 mm

DALON’s 20µm plastic disc filter is engineered for efficient and stable particle retention in compact fluid and air handling systems. Constructed from sintered polyethylene (PE), this disc provides a uniform pore structure, chemical resistance, and mechanical durability, making it ideal for low-pressure liquid or gas filtration in confined installations.

With a 34.5 mm diameter and 3 mm thickness, this wide-format disc filter offers broad surface coverage while maintaining low flow resistance—suitable for integration into filter cartridges, dosing equipment, and environmental instrumentation.


Key Features

  • Filtration rating: 20 microns (nominal)

  • Dimensions: 34.5 mm diameter × 3 mm thickness

  • Material: Sintered polyethylene (PE)

  • Uniform porosity for consistent flow and capture

  • Chemically resistant and corrosion-free

  • Washable and reusable for extended use


Applications

  • Inline particle filtration in water and chemical lines

  • Pre-filter for diaphragm pumps and valves

  • Sensor and analytical system protection

  • Dosing and irrigation control filter components

  • Compressed air or inert gas purification systems

FAQ – Frequently Asked Questions

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.
