Sy-Klone InternationalUSAhttps://www.sy-klone.com/Series 9000 Precleaner
-Mounts on all vertical and horizontal air cleaner housings, on all machines, replacing those with rain caps, tube body systems or internal precleaners
-Engineered polymer is rugged and gives the strength of metal with the weight of plastic. Patented sealed bearing cavity protects bearings from debris and moisture, preventing corrosion. Grease concentration of 20% instead of the typically used 10-15% concentration allows the Series 9000 to operate in extreme cold weather, down to -40½°F.
-Self-cleaning and routine maintenance-free, as no debris is trapped within the precleaner.
-Recommended Uses: Off-road conditions, construction, mining, forestry, landfill & waste, farming & agriculture, military, highway, and more.
-Expels all types of mixed debris, including mud, snow, rain, leaves, sawdust, chaff, and dust. The Series 9000 is the only precleaner on the market today that can handle wet debris such as snow and sleet as well as it handles dry debris!
-The standard included prescreen is adequate for most situations, and prevents clogs by keeping out debris larger than the ejection slot. In extreme winter weather, the removable prescreen can be dropped down the air inlet pipe to avoid blinding over with snow and ice.
-The perforated metal heavy-debris screen is recommended for extreme-debris situations such as landfill and forestry.		https://www.sy-klone.com/mm5/graphics/00000001/PDF_files/Support/Series9000/Universal9000MountingKitInstallation.pdfMore expensive and needs modification to install it
