Thread: Ventilation air filter

I've seen a couple of twin snorkel defenders back home - one feeding through the wingtop to the engine on one side, another feeding through the opposite wingtop to the heater matrix. Precleaner on top would do what you need.

Haven't tried it out yet, but in the bulldust of the cape region I'd have to be using these in my 110 I reckon

I am assuming you mean the air into the cab?? I have an 85 county which has the factory A/C unit under the bonnet. I made some ducting up and have a 200tdi snorkel feeding it. Uni filter make a foam pre filter that goes over the head of the snorkel, I just don't oil it up. I doesn't stop all of the dust be gete rid of a fair bit. Tim

I've been kicking around ideas for this and haven't come up with anything either. I was thinking of something that would be held in place by the screws of the intake cover but am concerned about how much it would take to clog it up.

The twin snorkel method is the best...

I was going to do it to Lara, after seeing how successful the thing worked on a friends Deefer...

Never got around to it

Plus, working where I do, nothing is a comparable for dust

Just a thought, how about fitting a snow cowl and placing a paper filter between the cowl and the grill on the wingtop? Another plus to this set up for me, without the paper filter fitted, is that it keeps the airbox dry and the drainage teets don't clog up with muck which used to cause a puddle in the passenger side once the airbox started to fill with water.





This pic shows the rubber gasket fitted to lift up the snow cover if you have chequer plate. I fitted it because I put in a cut down air filter paper element as an experiment which I then forgot about for about a year before I remembered about doing it. The results were a dirty filter and quite a bit of grit sitting on top of the filter.



And what it was designed for.....

I am thinking of something that drops in the duct from the wing top that is easily removed cleaned and refitted with out to much flow restriction.

This is how I did mine on the 300Tdi - I had a spare air ram top as I fitted a Donaldson pre-cleaner to the snorkel. In pic 1 you can see (just) a wire mesh to keep magpies out (yes - I hit a magpie right there) and behind it is a fine stainless mesh. For dusty conditions - pic 2 - I chucked a filter sock onto it. The bonus was that you get an air ram effect through the vents increasing flow and an extra bonus when fording - the water - bow wave - comes up over your guard you dont get it flow into the air box - mini snorkel. Hope that helps

p.s. I pinched the idea from Malcolm Douglas when he was driving Landies before Toyota got to him

I'm not sure which one of those two ideas I like best.

The "Snow cone" looks the goods for keeping water etc out.
But I quite like the look/idea of the "Forced air".

How much was the snow cover worth Brian?
