AAF Engine Overview Brochure
AAF’s Augmented Secondary Circuit (ASC) Filtration System for diesel and gas engines delivers superior protection in high dust environments. The innovative design of the ASC system removes up to 75% of the intake dust through inertial separation and positive extraction. These larger dust particles are immediately removed from the airstream into the secondary air circuit before reaching the filters. The remaining particles are captured by the versatile DuraPak filters.
Filters are surface loading and are cleaned with a reverse pulse of compressed air. The particles removed from the filters are extracted from the filtration system through the same secondary air circuit, avoiding re-entrainment and prolonging filter life. This results in a low and stable differential pressure and a high engine efficiency. Different filter options allow AAF to tailor an individual filtration system to meet customer requirements and to suit given operational and environmental conditions.
