TF-2415 Low-Pressure-Drop High-Efficiency Filter Bag (Reverse-Air Type)

The TF-2415 is engineered from 100% industrial polyester filament yarn, manufactured entirely in FILTER’s in-house integrated production system in Hsinchu, Taiwan — from yarn twisting, warping, weaving, heat-setting, surface finishing to final sewing. This vertical process guarantees product consistency, mechanical strength, and filtration stability.
With an actual service life of 3 to 5+ years, the TF-2415 series now also includes ultra-low-emission grades below 5 mg/Nm³, widely adopted across steel and foundry industries worldwide.

Key Features

  • Fully In-House Manufacturing: End-to-end production ensures consistent quality, reliable delivery, and full customization.
  • High Density & Low ΔP Design: Uniform pore structure (< 10 μm) prevents dust penetration; emissions maintained below 20 mg/Nm³,with optional versions achieving below 5 mg/Nm³.
  • Energy-Saving Performance: Pressure drop reduced by 30–70 mmAq vs. conventional short-fiber fabrics; air permeability 6–12 cc/cm²·s @ 200 Pa.
  • Anti-Static Safety Design: Stainless-steel conductive yarns every 20 mm discharge static and prevent explosion risks.
  • High Tensile Strength & Durability: Warp > 1500 Kgf/3 cm; Weft > 1200 Kgf/3 cm (JIS 1096); endures repeated reverse-air cleaning cycles.
  •  Precision Heat-Setting: Shrinkage < 3%; ensures dimensional stability and extended service life.
  • Optional Finishes: PTFE membrane, water/oil-repellent, or anti-static treatments available.

Applications

➢ Steel Industry — Reverse-air systems Ø292 × 10–12 m
➢ Foundries — Iron, copper, aluminum, and steel casting plants
➢ Other Industries — Wood, feed, chemical, flour, and tire manufacturing under low-temperature dust conditions

Patented Reverse-Air Dust Collection Design

We do more than just provide filter bags—we design from the perspective of the entire reverse-air dust collection system. Utilizing our proprietary patented design, we optimize airflow distribution and reverse-cleaning methods tailored to various operating conditions. This ensures more uniform dust detachment and more stable equipment operation.

Enhanced Reverse-Cleaning Efficiency, Minimizes filter bag blinding and clogging.
Stable Differential Pressure, Lowers fan energy consumption.
Extended Filter Bag Lifespan, Reduces replacement frequency.
Stable Emission Performance, Lowers the risk of exceeding emission limits.
