Reducing dust in your Filter

[Witchdoctor]

What are the good folks using to limit the dust getting into the air filter during dusty track adventures?

A snorkel inner or outer pre filter sock or cover.
using the factory paper element & blowing out daily with compressor.
washable filter & wash out every couple of days.

Doing a desert crossing soon with a large group & I know there will be times spent coping others dust.

Cheers
Dave

Sounds funny but...

Back off a bit... you all have UHFs. No need to be up each other’s arses.

Other than that the usual suspects tend to work.

You can just bang it out each day or two without a problem (carry a spare)

Just stay back far enough so that the dust has settled or at least most of it has.
A snorkel sock is very helpful as is one of those football inflator needle/gizmos that you can put on the end of your air hose to blow the dust out of your filter at the end of the day or next morning.

*A snorkel will reduce the amount of dust ingress to the air box.
*The snorkel socks are good and easy to clean.
*The standard paper filter is fine and cheap to buy, why not throw in half a dozen.
*You are far safer to brush or tap gently your air filter daily, using compressed air you risk damage to the air filter.
*Also on a Defender, the air box and air filter seals onto each other arent the greatest, use silicone spray on the joints.

I thought yours had a raised air intake??

Either way most fit a raised air intake....fit a nugget kit and it will become a snorkel.

As tombie says, You have comms so put distance between you and the car in front....cross winds makes for very clean driving

Agree with DAZZA, tap or shake the filter, avoid concentrated compressed air, if using compressed air than have a nozzle with the biggest hole (than you will have Tracy led keeping air up to it) and blow from inside out. LOL, I don’t reckon you would have room for a spare air cleaner.

As Dazza postsabove - take a look at the seals.

I attempt to assist the dustproofing of the seals by greasing them with rubber grease when assembling - seems to catch some - I guess vaseline would do if you didn't have the red stuff.

+2 to this
I use the rubber grease and it works well I have also found that genuine airfilters are best with little bypass.
The same cannot be said for certain other brands but in a pinch I will use Mahle or Mann.

If you do go down the path of a filter sock, I have used this one in the past and was very effective, but I then i had to carry cleaner and oil so I could clean at the end of the day (messy job!). Blowing out the genuine paper air filter with compressed air is an easier task.

Silicone or Rubber grease only.

Vaseline will react and attack the rubber.

Margarine handy when you run outa tucker after getting bogged in a corrugation after failing to lock center diff

I fitted the Nugget Snorkel sealing kit, helps greatly in ensuring the air entering the filter box is only from the head of the snorkel as opposed to water/air from leaks in plumbing.
I also installed a Sy-Klone International (http://www.sy-klone.com/) pre-cleaner. I noticed that Nugget had one and it works very well in removing the dust prior to going down the snorkel.
I also removed the flow director from the entrance of the airbox as it greatly slowed the rate of air entering the airbox(this also reduced the amount of negative pressure and therefore slowed the Sy-Klone).

On Cape York trip it greatly reduced amount of dust in filter. There was still a tiny amount but much less than those who didn't use a pre-cleaner.

As said before the very best way to prevent dust getting into the air cleaner is to keep out of the dust but if you can't avoid it or insist on tailgaiting the truck in front of you those tractor type pre cleaners work very well as long as you empty them out on a regular basis.
I am not sure how you would fit them on the rectangular tops of a snorkel But I imagine that they make them to fit.

Also useful for extracting yourself from the wreckage after running off the road due to the centre diff lock not being engaged.

Don't don't don't pull your air filter out just to have a look and give it a whack on something. I've always gone by the advice in this video.

That’s the good thing about the Sy-Klone, the dust particles are ejected out the side. Have a Captain Cook at the video on the site.
Donaldson’s have the dust accumulate at the bottom of the bowl
