High-Efficiency Needle Felt Dust Collector Media
The Polyester Filter Bag (PFB Series) is an industrial dust filtration media manufactured from premium-grade nonwoven polyester needle felt. Designed for dry, low-to-medium temperature applications, it serves as the primary particulate barrier inside baghouse dust collectors. Operating continuously at up to 110°C (230°F), it is the most cost-effective standard media in the Senotay lineup for environments that do not require the extreme heat tolerance of specialized PTFE or Nomex bags. Standardized with a PTFE surface coating, it provides excellent mechanical strength, moisture resistance, and a filtration efficiency ranging from 99.0% to 99.99%.
Core System Advantages
Cost-Effective Standard Media: The default, lowest-cost choice for dry dust collection streams operating under 110°C, providing exceptional value for cement, grinding, and milling operations.
PTFE Surface Treatment: Treated with a PTFE coating that dramatically reduces dust cake adhesion, allowing the bag to release particulate easily during pulse-jet cleaning. This extends cleaning cycle intervals and reduces compressed air consumption.
High Mechanical Strength: Nonwoven needle felt construction yields high tensile strength (>1200 N/5×20cm vertical) and excellent abrasion resistance, extending service life even under fluctuating air-to-cloth ratios and abrasive dust loads.
Key Technical Specifications
Media Properties: 500±10 g/m² nonwoven polyester needle felt with a thickness of 1.7–1.8 mm.
Filtration & Airflow: Achieves 99.0–99.99% efficiency with standard air permeability of 40–60 L/m²/s (@200Pa).
Thermal Limits: Rated for continuous operation at < 110°C and instantaneous surge temperatures up to 130°C.
Why Choose Polyester Filter Bag?
Lowest Cost Media: Provides the most economical balance of durability and performance for dry, low-to-medium temperature dust without paying for expensive high-heat materials like Nomex or PTFE.
Up to 99.99% Filtration Precision: High-density needle felt captures fine particulates across cement, limestone, grain, and timber processing operations.
Easier Cleaning & Extended Life: PTFE surface treatment reduces dust cake adhesion, cutting down on pulse-jet cleaning frequency and extending operational lifespan (6 to 24 months).
High Tear & Wear Resistance: Exceptional vertical and weft tensile strength (>1200 N) prevents bag rupture and premature wear against support cages.
Exact Fit Versatility: Manufactured to fit all standard cell plate diameters (100–280 mm) and custom lengths for rapid replacement.
