PLASTIC FILTER DISC 25X3.25 80MICRON

80µm Breather Filter Disc – Sintered PE, 25×3.25 mm

DALON’s 80µm breather filter disc is manufactured from sintered polyethylene (PE), specifically designed to support controlled air exchange and particulate protection in sealed or pressure-sensitive systems. With a 25 mm diameter and 3.25 mm thickness, this compact disc is ideal for applications requiring ventilation while blocking dust, splash water, or other environmental contaminants.

The sintered structure provides uniform porosity, allowing stable airflow and pressure equalization in electronics, battery enclosures, sensor modules, and fluid reservoirs.

Key Features

• Filtration rating: 80 microns (nominal)

• Dimensions: 25 mm diameter × 3.25 mm thickness

• Material: Sintered polyethylene (PE)

• Uniform, microporous structure for laminar gas flow

• Moisture- and corrosion-resistant for indoor/outdoor use

• Chemically stable and reusable design

Typical Applications

• Ventilation in electrical or control cabinets

• Pressure balancing in sealed housings and battery packs

• Breather ports for chemical or fluid containers

• Moisture and debris shielding in sensor enclosures

• Pneumatic system component venting or protection

Technical Advantages

• Consistent airflow: The sintered PE matrix allows stable ventilation while resisting ingress of contaminants.

• Environmental durability: Inert polymer body resists degradation from humidity, dust, and mild chemicals.

• Reusability: Washable using compressed air or light water rinse depending on contamination type.

• Dimensional accuracy: Ensures easy press-fit or bonded integration into standard breather housings.

FAQ – Frequently Asked Questions

Q1: What does an 80µm breather filter protect against?
It allows free airflow while blocking coarse particulates, water splashes, and airborne debris—ideal for protecting sensitive electronics or control systems.

Q2: Is the filter suitable for humid or outdoor use?
Yes. The PE body is moisture-resistant and functions well in moderate humidity or outdoor conditions.

Q3: Can this filter disc be reused?
Yes. It supports repeated cleaning via low-pressure air or gentle water flushing without structural or filtration degradation.

Q4: Can it be used with liquids?
While designed for gas exchange, it can tolerate occasional liquid exposure. For continuous liquid filtration, a finer pore size or different material is recommended.

Q5: Is the material chemically compatible?
Sintered PE is suitable for most neutral or mildly aggressive environments. For stronger chemical exposure, DALON also offers PTFE or PVDF alternatives.

Q6: Can DALON provide custom dimensions or materials?
Yes. We support full OEM customization including size, pore grade, material, and mounting adaptations for integration into your system.
