E-FILT Overhead Filtration System
(Industrial Terms: Plenum Filter / Spray Booth Ceiling Pad)
Core Composition
• Base Material: High-strength silicon-free synthetic fibers with anti-tear design
• Manufacturing: Gradient-compacted three-layer structure + full-depth adhesive curing
• Airflow Layer: Reinforced grid pattern on outlet side (diamond or square mesh options)
Key Features
✓ Intelligent Dust Retention: Captures 99%+ particles even at saturation
✓ Airflow Guidance: Special surface texture maintains ±5% velocity uniformity
✓ Extended Durability: 50% longer service life than standard ceiling filters
✓ Fire & Moisture Resistant: Certified for industrial safety standards
Typical Installations
Automotive spray booth plenums | Furniture curing oven airflow layers
Industrial coating line static chambers | Cleanroom primary filtration stages
