• The STG Donaclone™ is a powerful two-stage air cleaner that is used in a wide variety of heavy-duty mining equipment in heavy dust conditions. • Very reliable - only one critical seal. • Airflow throughout can be doubled by using two air cleaners • When the air cleaner is mounted above the cab or somewhere far from the engine to get above the dust cloud, choose the tubular inlet style, which will accept ducting into the inlet • Built-in Donaclone™ pre-cleaning tubes separate up to 97% of incoming dust to the dust cup before it reaches the filter, resulting in more thorough cleaning and fewer filter changes • Replacement primary filter choices - standard life filters (for scheduled maintenance) and Donaldson Blue® Ultra-Web® HD ultra-high efficiency, extended service filters for servicing by restriction • Uses standard airflow filters • Safety filter on all models
