AAF DuraShield SN Gas Turbine Conical/Cylindrical Cartridge Set – Cone Ø444/324mm + Cylinder Ø324mm, 660mm – Synthetic Nanofiber Media – MERV 15 / F9

AAF DuraShield SN is a high-efficiency synthetic cartridge filter engineered to protect gas turbines with sustained F9 (MERV 15) initial efficiency. It is supplied as a matched two-stage Conical/Cylindrical set: a tapered conical element (Ø444mm large end / Ø324mm small end) paired with a constant-diameter 324mm cylindrical element, both 660mm in length (approx. 17.5″/12.75″ OD x 26″ L), installed together in the same housing position. The 100% synthetic nanofiber outer layer is suited to high dust load environments with effective pulse cleaning recovery.

The DuraShield SN media is a multilayer construction combining an inorganic depth-loading synthetic with a polymer-based carrier layer that stabilizes the pleats during forming, producing well-formed V-pleat geometry for even particle loading and low obstruction to airflow. The media is hydrophobic and will not swell when saturated from prolonged high humidity, mist, or fog, and the cartridge uses a positive sealing gasket to remove any risk of air bypass.
