Our filter cloth are designed based on actual site conditions, not generic catalog assumptions. We help you select the right media to balance filtration efficiency, pressure drop, and service life.
Polyester Needle Felt
The most widely used and cost-effective filter bags for dry dust collection systems.Polyester Needle Felt provides a balanced combination of filtration efficiency, durability and cost.
Polyester Needle Felt Filter Fabrics Offer a Number of Key Properties:
- High Filtration Efficiency: Polyester has excellent particle retention, effectively capturing fine particles and dust.
- High Temperature Resistance: Polyester can withstand moderate temperatures, typically up to about 130-150°C (266-302°F).
- Mechanical Strength: It has good tensile strength and dimensional stability.
- Abrasion Resistance: The fabric is resistant to abrasion, prolonging its service life even in demanding filtration applications.
- Ease of Cleaning: Polyester needle felt can be cleaned and maintained easily, either through mechanical shaking, air pulsing, or washing.
