Don't Get Dusted!!

 

There’s a range of modern 4x4’s on the market suffering from dust ingestion issues, mainly those with a panel type air filter such as:

Toyota Land Cruiser 76/78/79 & 200 series, Toyota Prado 150 Series, Toyota Hilux GUN 122,123,125 & 126 Series, Nissan Navara D40 & D23, Mitsubishi Triton ML-MQ, Isuzu D-Max TF Series to name just a few.

The main reason for the dust issues on all these vehicles is the sealing edge of the filters. Rubber seals on plastic are not the best option when used in dusty conditions. Plastic air boxes warp out of shape when they heat up. Rubber does not warp the same way. As a result, the rubber seal does not compensate for the plastic going out of shape.

This is the reason all dirt bike filters are foam air filters with foam seals. The foam seal takes up the slack when the box air box warps. To fix the sealing issue on the Toyota Land Cruiser and Prado models we have added a foam seal to the sealing edge of the rubber seal. The sealing edge of these filters is flat so we can add a special foam seal that doesn’t breathe, so dust will not penetrate it.

The other style of panel filters uses a step style seal. These filters use a small contact point to seal on the air box. This is fine on road going car where dust is not an issue. On a 4x4 the dust will find its way past this point easily as the air box heats up. Due to the style of the seal, we can’t use foam to help with the sealing of the air box.

 

 

30 Years Of Experience Working For You
Unifilter has over 30 years of experience has equipped it with unparalleled expertise and know-how in the manufacture of air filter product for many and varied applications.

Whilst primarily renowned as a leader within the automotive and related markets, Uni Filter has the necessary resources to design, develop and manufacture custom, air filtration solutions for almost any requirement. 

Unifilter also designs and manufactures these same high performance air filters for many other diverse applications.

Especially where users demand high levels of air-filtration performance in particularly harsh environments 

 

 

 

High-Tech Foam Is The Key To High Performance
Fully reticulated (open cell) foam, as used in all Uni Filter products, consists of a honeycomb of tiny, interlocking cells of uniform size.

When treated with specially formulated filter oil, each passageway is like hundreds of very small centrifugal/oil bath filters connected one to another.

In this way, the foam traps and holds the particles throughout the entire volume of foam. 

The development of this unique foam represents a major advancement in air filtration technology. As a result, foam air filters, when compared with paper or cotton gauze equivalents, combine great airflow capability, huge dust holding capacity, and very high filtration efficiency for even extremely small particles. 

 

 

 

Features:

• Improved Performance through increased airflow.
• Improved protection through finer filtration levels.
• Substantial cost savings through serviceability and the ability to reuse the filter.
• To help improve the seal on these filters we have widened the sealing edge and made it flat rather than a point to spread the sealing point.
• We also make these filters ridged so they can’t deform under load like the O/E style filters.
• Our panel filters use two layers of foam.
• The outer layer is the work stage, and the inner layer is a backup stage.
• Effectively it’s two filters in one.
• Foam is also the best filtering material for dusty conditions.
• When the correct oil is used on foam filters they will continue to breath and filter, even when dirty.

 

 

 

Steps to Cleaning your Filter for Re-use:

• When cleaning only use Mineral turpentine or Unifilter’s Citrus Cleaner......... Petrol, Kero & Metho etc will shorten the life of the foam.
• Oiling and Cleaning foam air filters correctly is very important. Only use foam air filter oil when oiling foam air filters.
• Oil designed for Cotton air filters is NOT suitable. Only use a recommended oil that comes in a plastic bottle and is thick in consistency straight out of the bottle.
• Never use spray oils or oils that go on like water and then become tacky. These oils will shorten the like of the foam.
• Using a sealing grease around the filter sealing edge is also a good idea. We recommend using regular bearing grease. Some rubber sealing greases have chemicals in them that can affect the sealing foam.

 

 

 

Additional Uni Filter Info:

• Unifilter also manufactures a large range of snorkel pre-filters.
• These are a great addition when going off road and especially if travelling in convoy.
• Pre-cleaner are designed for use when its dusty.
• They can be used in normal driving conditions without affecting performance but to get a longer life out of them we only recommended using them when the conditions require their use.
