Product Description

Key Advantages

Chemical Resistance: Withstands pH 1–14 extremes
Durability: 100,000+ bend cycles without damage
Smart Cleaning: Surface membrane coating boosts dust release by 30%
Safety: Triple protection (anti-static/waterproof/flame retardant)

Working Principle

Working principle

The dusty gas passes through the fabric, and the particles are captured by the yarns and fibers. The higher the fiber density, the higher the pollutant capture efficiency. When the clean air is discharged, it either flows outward or inward to maintain the air temperature.
