series 9000

Engine Air Precleaners

Air filter life is directly related to the amount of debris ingested through an engine's air intake.Installing a Sy-Klone Series 9000® Air Precleaner as the first stage of an air intake system prevents >80% of dust and debris down to 5 micron from entering the system.

Keeping dust and debris off the filter results in longer air filter life, more efficient engine performance and decreased maintenance expenses.

The Series 9000® are Rugged, Self-Cleaning, Routine Maintenance-Free and applicable to air intake systems in construction, mining, forestry, landfill & waste, farming & agriculture, military, highway and more!

How it works

Stap 1: Air enters the underside of the dome through screened louvers.  This prevents clogging by blocking any particles larger than the ejection slot from entering the unit.

Stap 2: Curved particle-accelera-tor blades push dirt against the sidewall.

Stap 3: Strakes (angled ?ns) along the interior surface move heavier-than-air debris towards the ejection slot.

Stap 4:  Clean air continues to swirl down into the engine air inlet pipe.

The Series9000® are made of a Rugged engineered polymer construction which gives you the strength of steel (without the corrosion) at the cost of plastic and expel all types of mixed debris, including mud, snow, rain, leaves, sawdust, cha?, and dust.


Mounts on all vertical and horizontal air cleaner housings, on all machines, replacing tube body systems or internal precleaners.
