AMSOIL FLOWZAIR 2-Stage Air Filters

Already the leader in effective air filtration, AMSOIL has made a number of improvements to its air filter line, now known as AMSOIL FLOWZAIR Air Filters.

Engineered Air Filtration That Works!

The process of air filtration involves four fundamental filtration mechanisms, each contributing specific air filter performance benefits. The cellulose (paper) gauze, cotton and glass media filters marketed today fall short of offering true air filtration protection since design engineers were not successful in finding a way to incorporate all four principal filtration mechanisms into their final air filter design. Only AMSOIL technology conquered this challenge by successfully engineering the world-class FLOWZAIR Filter that uses all four filtration mechanisms to eliminate contaminants from entering your engine.

Faced with the reality that their air filters fall short in offering all-around air filtration excellence, other filter manufacturers accept substandard performance and try to lure you into believing that only one or two performance features matter to you.

Do Not Be Mislead! Accept No Substitutes!

Note: Filter marketers emphasizing only one performance characteristic, like airflow, who then promote that aspect as the principal reason you should use their air filters, care little of your costly engine investment! This single performance characteristic is accomplished at the detriment of other vital filtration functions.

To "filter is to "restrict." Therefore, small particle filtration efficiency can only be increased to the point that still allows adequate airflow. This is the classic Airflow vs. Efficiency Compromise, which predicts that as filtration efficiency is improved by reducing the size of the media openings, airflow restriction increases which reduces engine performance. One example of AMSOIL innovation is how we offset this compromise by engineering the unique and effective FLOWZAIR Filter with a greatly enhanced filter media surface area.

AMSOIL NEW XLPE/EVA BASE MATERIAL

The base of an air filter must provide and maintain a positive seal within the air filter housing. A quality seal prevents unfiltered air from bypassing the air filter and reaching the intake manifold and combustion chambers.  Most air filter designs use molded plastic or plastizol as the base material, which often fails to deliver an effective, long-term airtight seal.

The base material of panel-style AMSOIL FLOWZAIR Filters is now constructed of a highly advanced Cross Linked Polyethylene (XLPE) Closed-Cell Sponge material with Ethylene Vinyl Acetate (EVA). This new material offers several key advantages:

1) Ease of installation

Minimum force is required to install the air filter and achieve positive sealing of the air filter box.

2) Resistance to flexing and vibration

Suction-.ex and vibration often allow unfiltered air to sneak past an air filter's base material and into the engine.  The XLPE/EVA base material of AMSOIL FLOWZAIR Air Filters resists .ex and vibration and maintains its positive seal, forcing air to pass through the filter.

3) Resiliency

The new XLPE/EVA base material is highly resilient, springing back to its original shape even after months of constant compression in the air filter box. Following thorough filter cleaning and reoiling, this base material allows the filter to be reinstalled in the housing and deliver an airtight seal.

4) Long service life

The new XLPE/EVA base material effectively withstands the deteriorating effects of solvents, fuels and lubricants, providing long service life.

AMSOIL NEW METAL SUPPORT FOUNDATION

All AMSOIL FLOWZAIR panel configuration air filters now incorporate a heavy, rigid 18-gauge metal infrastructure with precision-formed 3.969 mm turbo perforations. This provides improved rigidity and support in service, while also allowing exceptional air flow.

AMSOIL NEW PACKAGING

Quality control has always been extremely important at AMSOIL. The improvements to the AMSOIL Air Filter line demonstrate the company 's dedication to manufacturing top-of-the-line products. In addition to the improvements made to the air filter design, AMSOIL has taken steps to improve the packaging. AMSOIL FLOWZAIR Filters are packaged prewetted with AMSOIL Super-Tack Foam Filter Oil. New heavy-duty HDPE bags prevent prewetted foam from leaking, ensuring a clean, professional-looking box.

AMSOIL FOAM FILTER MEDIA

For an air filter to be truly effective, it must offer sufficient contaminant storing capacity, adequate airflow and satisfactory particle removal. However, the classic problem faced by most air filters on the market is the "air flow vs. efficiency compromise." The smaller the air filter media openings, the more efficient the filter is at removing wear-causing contaminants. However, smaller media openings reduce airflow. Increasing the media openings improves airflow, but sacrifices filtration efficiency.

AMSOIL Reusable Foam Air Filters have long been the most effective air filters on the market, providing superior performance in the areas of efficiency, capacity and airflow. AMSOIL FLOWZAIR Filters still feature two layers of flame-annealed, oil-wetted foam, offering significantly more capacity and filtering area than traditional air filters. In fact, for each square foot of filtration media, total filtration surface area exceeds 2,000 square feet. Wear particles are effectively trapped and held while the engine receives a constant flow of clean intake air.

AMSOIL STAGE-1 FOAM FILTER MEDIA

The first layer (stage 1) of foam on the AMSOIL FLOWZAIR Filter features 8,000 pores per cubic inch and makes use of surface screening to stop particles larger than the pore openings, much the same way as a window screen stops bugs from entering a building.  The thickness of the stage 1 foam media allows additional particle removal through depth screening. As air flows through the foam media, dirt and contaminants are effectively screened out and stored.  In addition to surface and depth screening, AMSOIL FLOWZAIR Filters make use of diffusion and adsorption to remove airborne contaminants. Incoming air travel-ling through the foam filter media must navigate through a maze of open cell structures. As it moves from cell to cell, the air is continually changing directions, and contamination particles get diffused from the air and caught in the media. Adsorption to the AMSOIL Super-Tack Foam Filter Oil that coats the foam media effectively traps and removes contaminants from the air stream.

AMSOIL STAGE-2 FOAM FILTER MEDIA

Filtration via surface screening, depth screening, diffusion and adsorption continues on a finer scale in the second layer (stage 2) of foam on the AMSOIL FLOWZAIR Filter, which features 125,000 pores per cubic inch. Larger particles have already been filtered out in the stage 1 foam, so the full filtration capacity of the stage 2 foam is available for smaller particle removal and storage.

AMSOIL SERVICE INTERVALS

AMSOIL FLOWZAIR Filters may be cleaned, reoiled and reused for miles of trouble-free driving. Simply wash the filter with detergent and warm water, rinse, allow the filter to completely dry, reapply AMSOIL Super-Tack Foam Filter Oil and reinstall. Under normal driving conditions, AMSOIL FLOWZAIR Filters should be serviced at 25,000-mile or one-year intervals (whichever comes first).  In dusty conditions, the filter may require more frequent servicing.
