The STG Donaclone™ is a powerful two-stage RadialSeal™ air cleaner that is used in a wide variety of heavy-duty mining equipment in heavy dust conditions.
Allows 390 to 1760 cfm airflow throughput per air cleaner
Horizontal or vertical installation
Off-road, high dust conditions
Ideal for scrapers, earth movers, graders
Sure sealing system
Durable construction withstands extreme conditions
Easy to service
Donaldson Blue™ high efficiency, extended service filters are available.
Air Cleaner Features
Very reliable. Only one critical filter seal.
Airflow throughput can be doubled by using two air cleaners
Two body styles (peripheral inlet and tubular inlet) to accommodate location and ducting
Optional inlet shroud available for peripheral style
When the air cleaner is mounted directly on the engine and there is clearance around it for airflow, choose the peripheral inlet style (shown on right)
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
Choose the dust cup best suited to your maintenance practices. For choices see Accessories section
All models include a fitting for a filter service indicator
Replacement primary filter choices: Standard life filters (for scheduled maintenance) and Donaldson Blue™ high efficiency, extended service filters for servicing by restriction
Uses standard airflow filters
Safety filter on all models
How the Two-Stage STG Donaclone Works
Air is drawn in through the perforations in the lower part of the unit and forced down through a bank of Donaclone tubes. The Donaclone tubes spin the air so that centrifugal force causes the heavier dust particles to separate from the airstream.
While these particles fall into the cup at the bottom, the partially cleaned air is directed upward, into the primary filter in the upper portion of the unit for the second stage of filtration.
