SINTERED PE FILTER SHEET 500X500X4 20MICRON

DALON’s 20µm porous plastic sheet filter is a precision-engineered sintered polyethylene (PE) filtration medium designed for air, gas, and non-pressurized fluid applications. Measuring 500 mm × 500 mm × 4 mm, this flat sheet delivers a uniform 20-micron nominal pore structure, making it ideal for airflow filtration, dust shielding, enclosure venting, and pre-filtration in sensitive systems.

Manufactured using DALON’s ISO 9001:2015-certified process, the porous structure of this PE sheet enables consistent particle retention while maintaining stable airflow and mechanical integrity. It can be die-cut, laser-trimmed, or thermoformed into custom shapes, making it highly adaptable for OEMs in industrial automation, electronics, medical devices, and smart sensing equipment.

FAQ – Frequently Asked Questions

Q1: What does a 20µm porous PE sheet filter block?
It blocks fine dust, airborne particles, and fluid impurities above 20 microns, ensuring clean air or pre-treated fluid flow.

Q2: Can I cut or shape this sheet for custom applications?
Yes. The sheet can be easily trimmed using CNC, laser, or manual tools to fit your design or device requirements.

Q3: Is it suitable for liquid filtration?
Yes. While commonly used for air or gas, it can be used in low-pressure fluid applications such as reservoir vents or sediment screens.

Q4: Can the material withstand outdoor use?
Absolutely. Sintered PE is UV-resistant, water-stable, and chemically inert—perfect for both indoor and outdoor sensor protection.

Q5: Is this filter sheet reusable?
Yes. It can be cleaned with water, air, or mild solvents depending on the media it was exposed to.

Q6: What industries use this filter type?
Used in environmental monitoring, HVAC systems, electronic enclosures, medical sensors, IoT devices, and smart meter housings.
