New Intake

[rustystud]

Here's some pictures of my new Donaldson "Topspin" pre-cleaner. It seems to be a pretty good unit. The side of the housing has a slot (seen in picture 2 ) at the top and when driving air is forced in causing an impeller to spin. This spinning forces the large particles of dirt and dust to fling outward and then drop out the bottom of the housing. I've noticed the impeller also spins just from the intake of air from the engine running. We will see if this keeps the main air filter cleaner like they claim it does. For those wondering about the tarp over the cab. I have a soft top so to protect it and keep it from leaking I tarp it over whenever I'm not running it.

If I could provide a minor correction to your post above. It looks as though the topspin takes air in from the bottom perimeter, and as the impeller blades in the top of the housing spin the dust/dirt particles are accelerated and shot out of the 2 slots in the sides of the housing. How much is this Intake?

Here is a YouTube video of the Topspin in action:

I've looked into getting one, they aren't cheap. $75 or so iirc.

So does that mean the slot should face back, and not forward?

What is the size of the air filter opening? 4" ?

Wouldn't it be nice if the blades..Whistled.

Yes I think your right Hank. The directions that came with it where rather vague. I haven't seen this video either. I guess I have to rotate the housing to point the slot back towards the truck. The directions said you needed to keep the slot clear for air movement. I ASSumed it meant to allow air in not out.

Yes, 4" . Fits right on our intake. The cost was $106.42 shipped.

Can you tell us what model number pre-filter you purchased? Based on the link below it looks like the one for my Cummins 12-valve is H002394. This is because the factory Cummins head flows 150-160cfm.

The part number is "H002431-016-140" . For flow rates of 450-750 CFM .

Just now came across this thread and being as it's been 2+ years, how do you think the performance of the pre-cleaner has been to the life expectancy of the air filter?

It helped a whole lot. Since then I replaced the whole filter to an A3 style for more room in the engine compartment. That style has it's own "pre" filter on it.

I still have a few if you decide you want one, PM me.

Yea but it also looks like it might shave ice so bring your favorite flavoring. Mine is black cherry.
