Pre-Cleaners

We offer a range of pre-cleaners. All pre-cleaners do the same general thing; they keep contaminant from entering the intake duct, which prevents large or heavy contaminant from prematurely clogging your filter. Some devices collect contaminant in a bowl – some expel or eject contaminant directly – still others are connected via a scavenge system to route debris out the exhaust system. Donaldson offers six alternatives – so we can help you find the system that will work best for your application.

    • No wires or power requirements

Applications

  • Engine airflows of 1.4 to 45.3 m3/min / 50 to 1600 cfm 
  • Primarily used in medium to heavy dust environments
  • Great for off-road vehicles and equipment, including crawler tractors, farm tractors, skid steer loaders, mining, and fracking machines
  • Recommended mounting: on top of the metal air cleaner inlet stack. Do not mount on non-metal inlet stack.

Full View

Traditional pre-cleaner is cost effective and easy to use.

Features

  • Full-View pre-cleaner helps extend filter life
  • Centrifugal force in bowl separates up to 75% of incoming dust before it enters the engine air intake system
  • Low maintenance
  • Durable, lightweight, noncorrosive construction
  • Full-view plastic bowl lets operator easily see when service is needed

Applications

  • Agricultural and construction equipment
  • Recommended mounting: on top of the engine intake stack

 

DonaSpin™

The Donaspin™ Pre-Cleaner extends the life your air filter by removing up to 90% of the dirt and contaminant before it reaches the filter and ejecting it automatically via the exhaust system.  Donaspin is designed especially for equipment operating in very heavy dust/debris environments.

Features

  • Built-in louvers spin air to separate up to 90% of incoming dirt and debris from the air intake system
  • Works as part of a scavenged flow system to continuously expel pre-cleaned contaminants through the exhaust flow

  • Recommended mounting: on top of the air inlet stack

 

In-Line Separators

Two-stage cleaning for unexpectedly heavy dust/moisture conditions

When your truck is being used in heavier-than-anticipated dust or moisture conditions, you may not have to replace the entire air cleaner. The problem may be solved by adding a Donaldson in-line separator. This enables an over-highway vehicle, which usually sees only light dust, to be easily and economically adapted to off-road medium to heavy dust conditions.

Features

  • Economical way to convert air intake system from light dust to medium to heavy dust condition
  • 80% water removal efficiency
  • 70% dust removal efficiency

Applications

  • Vertical model: On/off road, mounted on inlet tubing or cowl mounted directly to air cleaner – Compatible with engine airflows of 14.2 to 42.5 m3/min / 500 to 1500 cfm
  • Horizontal model: On/off road, typically mounted underhood – Compatible with engine airflows of 2.8 to 40 m3/min / 100 to 1400 cfm
