High-Efficiency Micro-Porous Pleated Air Filter – Superior Filtration for Critical Environments

Introduction

In industries where air and liquid purity directly impact product quality, worker safety, and equipment performance, Micro-Porous Pleated Filters deliver unmatched filtration efficiency. Engineered with precision, these filters combine high dust-holding capacity, low pressure drop, and extended service life—making them ideal for demanding applications in pharmaceuticals, semiconductors, food processing, and commercial HVAC systems.

At Lefilter, we manufacture industrial-grade pleated filters that exceed international standards, ensuring your operations run smoothly with minimal.

Why Our Micro-Porous Pleated Filters Stand Out

1. Advanced Multi-Layer Filtration Technology

Deep-Pleated Design – Maximizes surface area for superior particle capture while maintaining optimal airflow.

High-Efficiency Media – Constructed with microglass fiber, melt-blown polypropylene, or PTFE membrane for sub-micron filtration.

Low Energy Consumption – Reduced initial resistance (as low as 30 Pa) cuts HVAC operational costs.

2. Built for Durability & Heavy-Duty Use

Reinforced Frame Options – Choose from stainless steel, aluminum, or ABS plastic for corrosion resistance.

High-Temperature & Chemical Resistance – Withstands up to 120°C (special grades available for extreme conditions).

Fire-Retardant & Hydrophobic Options – Ideal for oil mist filtration, cleanrooms, and hazardous environments.

3. Customizable for Any Application

Multiple Efficiency Ratings – From MERV 8 to HEPA H13/ULPA U15, meeting ISO 16890, EN 1822, and ASHRAE 52.2.

Flexible Sizing – Standard dimensions (e.g., 24"x24"x12") or fully custom designs.

Specialty Coatings – Anti-microbial, hydrophobic, or static-dissipative treatments available.

Technical Specifications

Key Applications

1.Pharmaceuticals & Biotechnology – Ensures sterile air in cleanrooms and filling lines.

2.Semiconductor Manufacturing – Eliminates airborne contaminants in chip fabrication.

3. Food & Beverage Processing – Complies with FDA and HACCP hygiene standards.

4. Commercial HVAC – Improves IAQ (Indoor Air Quality) in hospitals, airports, and data centers.

5. Industrial Dust Collection – Captures fine particulates in welding, laser cutting, and powder handling.

Competitive Advantages

1. Longer Lifespan – 2-3x service life compared to standard 

2. Energy Savings – Lower pressure drop reduces fan power consumption.

3. Global Certifications – ISO 9001, CE, RoHS, and industry-specific compliance.

4. OEM/ODM Support – Custom branding, private labeling, and bulk discounts.
