High-Temperature Filter Bags for Power & Cement | PI630G Solution


The Farrleey PI630G is a premium industrial filter bag engineered to deliver exceptional performance and safety in the most demanding high-temperature and high-risk environments. By combining the strength and heat resistance of Polyimide (PI) with the superior chemical and non-stick properties of PTFE, it is specifically designed to handle combustible dust, offering unparalleled reliability and an extended service life.


Key Advantages at a Glance:

  • Maximum Operational Safety: The integrated anti-static PTFE scrim ensures surface resistivity remains below 10^9 Ω/sq, effectively dissipating static charge and significantly reducing the risk of ignition in hazardous environments. Complies with IEC 62631-3-2.

  • Unmatched Thermal Durability: Go beyond standard limits. The PI630G operates continuously at 250°C and can withstand short-term thermal shocks up to 280°C, protecting your system from unexpected process upsets.

  • Rugged Construction for Long Life: With exceptional tensile strength (MD >800 N/5cm, CD >1000 N/5cm), our filter bags resist mechanical stress, abrasion, and frequent pulse-jet cleaning, minimizing downtime and replacement costs.

  • Efficient and Economical: The carefully calibrated air permeability range ensures an ideal balance between high dust capture efficiency and low, energy-saving pressure drop.
