  • Reduced downtime
  • Reduced maintenance costs
  • Self-cleaning
  • Lightweight
  • Easy to install
  • Durable polymer design

Sy-Klone pre-cleaners are state-of-the-art products that reduce maintenance costs and downtime for all diesel applications. They are recommended for construction, farming, mining, forestry, or any
other segment where operating conditions are severe. Sy-Klone pre-cleaners keep air filters clean, extend the life of the filter and maintain engine performance. Positioned at the beginning of the air
intake, Sy-Klone Air pre-cleaners eject the majority of dust/dirt particles that are heavier than air.

How the Sy-Klone works:
1. Dirty air passes through prescreen and enters through recessed vanes at the bottom of the Sy-Klone.

2. The curved particle accelerator rotates much faster than the incoming air, capturing debris, which is passed down the length of the particle
accelerator’s straked vanes.

3. The debris is then deposited on the inner wall of the separator chamber.

4. As the particle accelerator spins, it sweeps debris that has deposited under the strakes onto the inner wall of the precleaner, from where
it is ejected.

5. Clean air continues to spin upward, being compressed, and forced into the air inlet opening.

To properly size a Sy Klone precleaner you will need to know the correct airflow
of the engine in cfm (m3/min.) and the Outside Diameter of the Air Intake. For
optimum efficiency, select the precleaner where the cfm (m3/min.) falls in the
upper end of the ranges shown.

NOTE: Do not size a Sy Klone Precleaner solely based on the Air intake
dimension!

Precleaners should not be mounted against any part of the machine as space is needed to allow air to enter into the precleaner.
Fleetguard does not recommend putting precleaners high in the air on an extended pipe as the further away the air intake is from the engine,
the more added restriction.
