Pre Cleaners


Largo offer a range of pre-cleaners. All pre-cleaners 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 whilst others are connected via a scavenge system to route debris out the exhaust system.


Strata™ Cap

The scavenged Strata Cap pre-cleaner removes up to 96% of incoming contaminant. It is designed for the most demanding heavy dust environments in the construction and mining industries

Separates up to 96% of incoming contamination per ISO 5011/SAE J726.
Significantly extends air filter life
Reduces air filter servicing and replacement
Lowers operating cost per hour
Separates more than 99% of particles 20 microns and above
Light weight and low profile for maximum operator visibility
Robust design:
No moving parts
Built in rain cap
No bowl to clean or empty
UV resistant plastic construction
Simple installation:
Install outside the engine compartment – no underhood space required
No wires or power requirements
Requires standard scavenge components

Applications
Accommodates a range of airflows from 350 to 1,300 cfm (9.9-36.8 m3/min)
Primarily used in heavy dust environments
Great for off-road vehicles and equipment from crawler tractors to farm tractors to skid steer loaders
Recommended mounting: outside of engine compartment on top of the air cleaner inlet stack


TopSpin™ HD

TopSpin™ HD will extend primary air filter life, boost system efficiency and extend engine life in medium to heavy dust environments

Features

Rugged one piece aluminium hood with recessed discharge louver sheds flying debris
One-piece stainless steel impeller is the only moving part. Dual bearings ensure reliable performance
Stainless steel clamp with locking nut makes installation quick and secure (Clamp is included)
All the interior components are solid stainless steel to resist dirt, water, heat, and debris encountered in demanding environments
Greatly extends air filter life
Reduces air filter usage
Lowers cost per operating hour
Automatically ejects mixed debris
Self-cleaning/self-scavenging
No maintenance to clean bowl
No exhaust ejector required
Easy installation
Quick installation
One clamp to tighten
No wires or power requirements

Applications
Engine airflows of 50 to 1600 cfm (1.4-45.3 m3/min)
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

Greatly extends air filter life
Reduces air filter usage
Lowers cost per operating hour
Automatically ejects mixed debris
Separates more than 99% of 20 micron and above particles
Self-cleaning/self-scavenging:
No maintenance to clean bowl
No exhaust ejector required
Easy installation:
Quick installation
One clamp to tighten
No wires or power requirements
Dual mounted bearings:
More robust design
Extends bearing life
Lighter Weight:
Lighter than competitive pre-cleaners
Lighter than Donaldson Full-View pre-cleaner

Applications
Engine airflows of 80 to 1500 cfm (2.3-42.5 m3/min)
Primarily used in medium to heavy dust environments
Great for off-road vehicles and equipment from crawler tractors to farm tractors to skid steer loaders
Recommended mounting: on top of the air cleaner 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
One-bolt cover retention for easy service. When dirt reaches the level of the arrow, remove top nut and plastic body, then empty – no tools require
Mounting clamp included

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
Durable, corrosion-resistant steel construction
High efficiency with low restriction
No maintenance. Self-cleaning. No moving parts.
Mounting clamp is included

Applications
Vehicles: agricultural equipment, construction and waste haul vehicles
For engine airflows of 305 to 800 cfm
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 500 to 1500 cfm
Horizontal model: On/off road, typically mounted underhood – Compatible with engine airflows of 100 to 1400 cfm
