Air Conveying System

The Pneumatic Transport Solution for Lightweight Materials

Air conveying systems provide efficient, gentle transportation of plastic flakes and other lightweight materials throughout recycling facilities. These closed-loop pneumatic networks move processed materials at high speeds while minimizing degradation and contamination risks associated with mechanical conveying.

Engineered for Delicate Material Handling

Precision-designed with variable frequency drive (VFD) controlled blowers, these systems maintain optimal air velocities (typically 15-25 m/s) to prevent material compaction or fiber damage. The smooth interior surfaces of food-grade stainless steel or abrasion-resistant polyethylene tubing ensure frictionless material flow. Specialized diverter valves enable routing to multiple destinations without cross-contamination.

Operational Advantages in Plastic Recycling

• Gentle transport preserves flake integrity and reduces fines generation
• Closed system prevents moisture absorption and dust emissions
• Energy-efficient design with 30-50% lower power consumption than mechanical systems
• Self-cleaning operation eliminates material buildup
• Modular design allows easy system expansion or reconfiguration

Key System Components

• High-efficiency cyclones with 99%+ separation efficiency
• Rotary airlock feeders for controlled material introduction
• In-line magnetic separators for metal contamination removal
• Explosion-proof designs for processing combustible materials
• Smart sensors for real-time material flow monitoring

Maintenance for Optimal Performance

Regular inspection of wear components (elbows, diverters) prevents unexpected downtime. Filter bags require periodic replacement based on differential pressure readings. Quarterly blower maintenance ensures consistent airflow, while annual system balancing maintains energy efficiency. Many modern systems incorporate predictive maintenance capabilities through vibration and performance monitoring.

Material-Specific Configurations

Systems can be customized for different material characteristics:

• Low-velocity designs for fragile PET flakes
• High-capacity systems for PP/PE regrind
• Heavy-duty configurations for filled materials
• Sanitary designs for food-grade applications
• Anti-static systems for sensitive electronic applications
