Here are the photos of the aspirator. The hose is piped into the bottom of the air cleaner box, it runs to the small canister you see in the picture and then is plumbed into the exhaust. The result is the dirt is sucked out of the filter and is vented out with the exhaust. Like I mentioned before in real dirty conditions it shines the inside of the exhaust pipe. Works awesome. Almost eliminates replacing the air filter. I have had it serviced twice and had the filter replaced at 500 hours each time just because. I saw this system on a 445 Series 3 machine, however it does not sound like it is available on the 465 or 450 due to lack of room. That is too bad. The 465 has a different system with a containment system of sorts in the cap ofo the air cleaner housing. It is better than the 95XT I had but not near as effective as this aspirator. Another bonus is with this system I can work in Yellowstone Park without issues. They are very touchy on the exhaust systems of heavy equipment.
