DuraShield® SN

Synthetic nanofiber filter cartridge for gas turbines

The DuraShield® SN gas turbine filter cartridge has been specifically designed to protect gas turbines in high dust environments with prolonged high humidity. The high F9 (MERV 15) initial efficiency provides sustainable performance over its operational life, increasing availability and reducing compressor fouling. The 100% synthetic nanofiber media is hydrophobically repellent, withstanding high humidity from mists, fogs, or sustained levels of rain.

The DuraShield® SN excels in extreme environments where both high dust load and high humidity are combined. The product has excellent pulse recovery to maintain a low pressure drop and with a high dust holding capacity, even in this type of extreme environment filter life remains long.

Features & Benefits

  • The synthetic media will not swell when saturated and differential pressure will not spike during prolonged high humidity.
  • Nanofiber outer layer provides excellent dust release during pulse cleaning, which helps to lower energy costs and improve efficiency.
  • Optimised pleat geometry reduces pressure drop and increases dust holding capacity.
  • Several different geometries ensure compatibility across the majority of manufacturers’ specifications.
