Description
Multi-tube air precleaners are designed to separate dust and contaminant particles from the airflow before they reach the main air filter, helping extend filter service life and reduce maintenance requirements.
Based on centrifugal separation technology, these systems are particularly suitable for heavy-duty applications in high-dust environments, including mining, agricultural equipment, earthmoving machinery and defence vehicles.
Features & Configurations
Dust Separation
The systems can achieve pre-separation efficiencies of up to 96% with a dust scavenging system and up to 90% without scavenging, based on tests conducted using ISO coarse test dust.
Customizable Configurations
Solutions are available with or without scavenging, using different types of separator tubes according to the required airflow rates, available installation space and specific application requirements.
Materials & Construction
Support structures can be manufactured from steel, aluminium, stainless steel or combinations of materials, depending on project requirements.
Technical Support
Borserini offers customized solutions tailored to specific application requirements. Images of additional installations, performance curves and separation efficiency charts are available upon request.
Application Examples
John Deere Tractor
Externally mounted multi-tube air precleaner installed on a John Deere tractor, designed to separate dust before it reaches the main air filter.
Komatsu D375A Bulldozer
Air pre-separation solution developed for a Komatsu D375A bulldozer.
The images show the precleaner installed on a Donaldson FRG air cleaner assembly.
Komatsu HD785 Dump Truck
Air pre-separation system consisting of a single unit with 138 separator tubes, connected to three Donaldson air cleaners.
The configuration shown operates without scavenging and requires periodic emptying of the dust collection chamber.
A similar configuration equipped with an electric dust extraction system is also available to remove separated dust.
Defence Vehicles
Customized solution for military applications, combining standard air filter elements with an integrated air pre-separation system.
Separated dust is evacuated using a high-performance blower.
The system can be configured according to technical requirements and application specifications, providing a complete air filtration solution.
