STG Donaclone ™ Air Cleaner
STG Donaclone: Field Proven and Reliable Heavy-Duty Workhorse for Construction & Off-Highway Applications
That Donaldson's STG Donaclone™ is arguably the most commonly used air cleaner, on the widest variety of heavy-duty equipment in the world, is a testament to its reliability and durability. With its two-stage air cleaning, heavy- duty construction, and variety of configurations, the STG works well in many heavy-duty applications like scrapers, crawlers, dumpers and haul trucks.
Powerful Two-Stage Filtration
The first stage of this powerful air cleaner consists of a cluster of Donaclone ™ the incoming air to create a centrifugal force that separates up to 95% of the dust and dirt in the airstream. Donaclone tubes have no moving parts – so there is nothing to break down or maintain. They function properly whenever the engine is running. This pre-cleaned dust is collected in a dust cup on the bottom of the air cleaner housing. The second stage of filtration is the primary filter, a cylindrical- shaped unit of specially-developed pleated filter media, designed to trap and stop dust particles, both large and small. The result is air to your engine that is up to 99.9% contaminant free! tubes. They spin ™
This STG Donaclone, mounted on a large mining machine, is protecting the engine from harmful dirt in this severely dusty environment.
If you're replacing a worn out air cleaner, be sure to check ductwork, clamps, and other intake system parts that may also need replacing. STG air cleaners feature a corrosion-resistant, chemical- resistant polymer coating. This black coating isn't paint, rather it's a pigmented polyester that provides a long-lived, hard protective finish.
A safety filter, which fits inside the primary filter, is standard on all models for protection during primary filter changeout. Physical orientation does not affect the proper functioning of either cleaning stage! The STG operates well mounted horizontally or vertically. (Note that if mounting horizontally, the Vacuator™ Valve option on the dust cup is necessary.) Mounting: Sturdy mounting brackets are attached to the top section of the STG; you will also need to order one separate mounting band for the lower body.
