DuraShield® B

Filter cartridge for gas turbines with blended media

The DuraShield® B is AAF’s entry-level product in the DuraShield product range. Suitable for dry, medium dust load environments, the DuraShield B is a durable media designed for pulse cleaning and specifically designed for gas turbine intakes.

The DuraShield® B has an M6 (MERV 12) efficiency, although this is classified as F8 against the EN779:2002 standard. This is a tried and tested product and has been in the DuraShield portfolio for many years. Like all cellulose/synthetic blends an application assessment should be made when used in humid or very high dust applications.
