AAF Gas Turbine Overview Brochure
The DuraPak B is AAF’s entry-level product in the DuraPak product range. Suitable for dry, medium dust load environments, with a durable media designed for pulse cleaning and specifically designed for gas turbine intakes. The DuraPak B is a direct replacement for existing ASC filter houses without modification to the holding arrangement.
The DuraPak B has an MERV 12 or M6 efficiency, although this is classified as F8 (MERV 15) against the EN779:2002 standard. This is a tried and tested product and has been in the DuraPak portfolio for many years. Like all cellulose/synthetic blends, an application assessment should be made when used in humid or very high dust applications.
Suitable up to moderate dust levels
Durable media
Very low pressure drop
The site in question operates several gas turbines in Dubai, UAE at an Aluminium Smelter. All originally fitted with reverse pulse cartridge systems, the operator could not achieve a filter life beyond 9 months. There was also evidence of compressor fouling and hence reduced engine performance. An ASC Filtration System was installed and the results showed a step change in performance levels.
