To address the need for extra
protection from dust and dirt with washable/reusable oil-impregnated
cotton gauze filters, aFe developed a new filtration technology so
revolutionary that we applied for and received a patent. This new
filtration technology is aptly called Pro-GUARD 7. 5 layers of
progressively finer mesh medical grade cotton gauze with micro fibers
that attract smaller and smaller particles as air passes through is
combined with 2 layers of random-porosity non-woven synthetic polyester
fabric. These 7 layer combination of cotton gauze and non-woven
polyester is sandwiched between 2 layers of epoxy coated aluminum wire
mesh.
Because of compression ignition of diesel engines, tolerance are much tighter than in a gasoline spark ignition engine. These tight tolerances require clean air and lots of it. Diesel engines require 7 times more air than a gasoline engine of equivalent size. The patented Pro-GUARD 7 filter media delivers more cool clean air needed for extended engine life, better fuel economy and additional power



High Efficiency
Efficiency refers to a filters ability
to efficiently filter out the dust and dirt particles from entering the
air intake of the vehicle over time. Pro-GUARD 7 was developed
with the need for high efficiency in mind. Generally accepted SAE
standard for filtration efficiency is 99.5% fine dust. There is
course dust efficiency and fine dust efficiency. 99.50% course
dust efficiency is not difficult to achieve. Typical
performance/cotton gauze filters will five you the airflow you need,
but they sacrifice filtration efficiency to do so. They
achieve the 99.5% course dust efficiency. The 99.5% fine dust
efficiency is a different matter. Fine dust is what you want to
keep out in the tighter tolerance turbo diesel engine. Pro-GUARD 7 has
been tested to surpass 99.5% fine dust filtration efficiency while
delivering high airflow.

Holding more dust simply means that you will end up with a longer interval before needing to service your filter. The progressive nature of the cotton gauze and the deep pleats enable Pro-GUARD 7 to hold over 11 times the dust of a paper filter before needing to be cleaned or serviced. The layers of cotton and synthetic media are able to hold the dirt while still allowing air to pass through. The paper and foam filter elements become clogged quickly as dirt particles deposit onto the face of the filter media...that mean less air getting to your engine and more frequent and shorter service cycles.
The less often a filter requires cleaning or service, the better. The more dust a filter holds, less often the filter has to be serviced. With Pro-GUARD 7 filter media's great dust holding capacity, typical service interval is 50,000 miles in normal driving conditions and 25,000 miles in severe dust environments. Longer service intervals from greater dust holding capacity also reduces the chances that the filter will be sucked into the intake system. As a filter gets clogged with dirt, it passes less and less air. As the turbo continues to draw air into the engine, vacuum can become so great that a clogged filter with all the accumulated dirt can get sucked into the intake system. Considering the maintenance costs involved with work and fleet vehicles, minimizing the frequency of maintenance translates to a better bottom line.
Allowing more cool, clean, unrestricted airflow is a key element in increasing engine performance. Pro-GUARD 7 filtration technology allows airflow that matches the performance of cotton-gauze filters. Increasing the amount of air the engine breathes and doing it with less effort increases horsepower and torque. As an engine performance more efficiently, it improves fuel mileage as long as driving patterns remain the same. Better airflow through the engine also translates to lower exhaust temperatures which is critical to prolonging the life of the turbo. Pro-GUARD 7 offers this level of performance without sacrificing filtration efficiency.
Giving your engine more air and letting it breathe easier translates simply into more power. Because the engine gets the air it needs without impediment, it gets it faster and with greater velocity. Plenty of quick, fast air translates to faster turbo spool up, better acceleration and more torque which is the sensation you really feel as you give the vehicle gas. You will especially feel the power when you are towing and climbing a hill.
Better Value
Extended service interval, higher airflow, high filtration efficiency, better fuel economy and better protection help with the total cost of vehicle ownership and operation. Value is more than what you pay for a part. It is the combined impact of the part on the total cost of owning the vehicle. This involves not only the financial impact but also the enjoyment you receive from the part. The Pro-GUARD 7 filter media off tremendous value by increasing power, lowering maintenance cost, and providing years of great "seat of the pants" enjoyment.
