WIX history has deep roots in heavy duty filtration. WIX understands what keeps maintenance managers up at night and WIX knows how filtration can significantly impact the long-term profitability of an entire fleet.

WIX premium filters enable the lowering of long-term costs by lengthening maintenance intervals while continuing to protect vital engine parts as well as or better than traditional filters changed at shorter intervals.

That’s why WIX heavy duty filters can withstand whatever the industry demands. Testing and benchmarking proves it. And, WIX experienced engineers, who are responsible for more than 30 U.S. patents, ensure WIX stays ahead of every technological change in the industry.

Off-highway heavy-duty construction engines add another element to the equation as they demand even greater filter performance in efficiency, capacity and structural integrity in order to combat their harsh working environment.

New innovations in filtration, including new forms of synthetic/cellulose filtration media, vastly improve particulate retention efficiency without sacrificing filter capacity. This is significant, as it is critical that heavy-duty filters remove as much contaminant as possible without restricting the flow of lubricants, air or fuel to vital engine components. Compared with traditional organic cellulose media types, engineers can more easily customize the performance characteristics of the new synthetic media to provide the best flow vs. restriction profiles, efficiency capability, and contaminant holding capacities.

Another innovation in filtration is WIX’s ability to produce air filters with precise embossed pleats, stabilization beads and various media basis weights designed to maximize the filtration media surface area. With greater media surface area, filters can trap more contaminants while maintaining low air flow restriction for efficient engine performance.

When coupled with new high-performance lubricants and fuels, today’s heavy-duty filters can be even more powerful engine-maintenance tools. Pairing premium filters with cleaner burning fuels and high-quality lubricants that contain fewer contaminants can exponentially increase both engine performance and the time between necessary lubricant and filter changes.

Although premium filtration products cost slightly more up front, they can produce long-term savings. When compared with the cost of lost productivity, engine overhauls or new vehicles, paying a little more for the innovations inside premium filters is low-cost insurance that pays great dividends.

Heavy Duty Oil Filters

Oil is the life-blood of an engine, which means the oil filter should never be taken for granted, especially in harsh heavy-duty environments. The small price maintenance teams must pay for premium filters is well worth the cost when you consider the components that make up an oil filter.

Premium oil filters provide many benefits over their cheaper counterparts, including:

• Thicker base plates (standard .155 inch thickness) for consistent thread strength, easier thread engagement, positive inner-element support, and consistent gasket compression.
• Sturdy element supports designed to resist all fluid types, vibration, and high and low temperatures, which will not deform under constant spring-load pressure.
• Heavy duty center tubes and cans which can withstand exposure to a wide range in flow and pressure.
• High tech media and other technological improvements that can give premium filters the edge over OE designs.

WIX heavy duty oil filters are also available in XD (extended drain), XE (extra efficiency) and ecoLAST (double oil drain intervals) versions.

Heavy Duty Air Filters

It only takes eight ounces of dirt to destroy the engine of a heavy duty machine. This fact makes WIX air filters, which are 99.9 percent efficient, critical to the life of an engine.

There are many components to consider when selecting air filters. One of the most important elements is the type of sealing gasket. WIX premium air filters use more expensive compounds like silicone, rather than foam or rubber gaskets, in order to assure a proper seal under harsh conditions.

When selecting air filters take a close look at the media or paper. WIX premium air filters feature embossed pleats and pleat stabilization beads that help the filter trap more dirt and last longer.

Another key element of heavy duty air filters is the end caps, which should be designed with structure and fit in mind. WIX premium heavy duty air filters often go to the added expense of adding metal end caps with handles, which allows for ease of installation and helps ensure that the filter becomes one with the housing to protect the engine.

Another innovation is WIX’s ability to produce air filters with precise embossed pleats, stabilization beads and various media basis weights designed to maximize the filtration media surface area. With greater media surface area, filters can trap more contaminants while maintaining low air flow restriction for efficient engine performance.

Heavy Duty Fuel Filters

The fuel filter is often the forgotten filter. Yet the fuel put into diesel and off-road equipment, more often than not, contains contaminants such as dirt, rust, scale and water. These impurities can plug fuel injectors and carburetors, resulting in engine malfunction or deterioration.

These contaminants often originate from dirty and rusty storage tanks, and as the vehicle ages, from corrosion within the fuel system components. All the more reason to invest in high-quality WIX fuel filters and to maintain them at recommended intervals.

It is also good to remember that the primary fuel filter for any diesel engine should always be a fuel/water separator. All diesel fuel contains some water, and removing it ensures longer diesel injection system life and productive engine uptime. This is why WIX fuel filters feature Quickvent® water removal capabilities.

The last few years' alternative fuels, such as biodiesel, have drawn considerable attention in the industry. When converting to a biodiesel blend, it’s important to remember that biodiesel has a “solvent” quality, which will result in the cleansing of the fuel system, and may subsequently clog the fuel filter. After the initial clean up of the fuel delivery system, fuel filter service intervals will return to normal under biodiesel utilization. Biodiesel also has a tendency to attract more water mixing with the fuel, increasing the need for proper fuel/water separation.

Heavy Duty Cabin Air Filters

The protective passenger cabin air filter is a critical part of a vehicle’s ventilation, heating, air conditioning and defrosting (HVAC) system. In addition to the benefits of breathing clean air, when the cabin air filter is dirty or clogged, less air passes through the filter, making it harder to keep the air clean and flowing, hampering the performance of the HVAC system and shortening the life of vital system components.

Using advanced filter media innovations, WIX offers a full line of high-efficiency cabin air filters for heavy trucks, buses, and off-highway vehicles.

Heavy Duty Hydraulic Filters

Heavy truck, off-highway, agricultural and construction vehicles and equipment depend on hydraulic fluids to power many of their critical functions. To operate at peak efficiency, fluid contaminants must be kept to an absolute minimum – no small challenge given the rugged environments these vehicles and equipment work in every day. WIX has applied its superior filter design and manufacturing expertise to produce high quality hydraulic filters for a variety of applications.

Heavy Duty Coolant Filters

Surprisingly, 53 percent of all catastrophic, premature diesel engine failures are directly related to improper cooling system maintenance techniques and habits. Providing the correct water, antifreeze, filters and supplemental coolant additives is critical to coolant system life.

WIX has applied years of research and development in filter media technology to create the industry’s highest performing coolant filters. Coolant filters help maintain proper heat transfer by filtering solid contaminants, like rust and sand particles, from the coolant and by minimizing corrosion and deposits in the cooling system. This results in a clean, well-functioning coolant system, proper heat dissipation, and engine efficiency through improved heat conductivity. WIX coolant filters also provide a method to introduce necessary supplement Coolant Additives when required.

Field-testing is also vital to proper coolant system maintenance. Maintenance crews should take advantage of available field test strips, as well as full laboratory coolant-analysis programs. Test strips provide a quick and simple method to check cooling systems on-site to make sure they are properly protected; a full laboratory analysis provides a complete and in-depth test procedure that can aid in troubleshooting, verifying the service interval for the system, and testing if the filtration products and/or the chemical additives are performing and protecting the way they are expected.

WIX offers filters, additives, test strips, and field expertise to assist fleets in determining the proper coolant maintenance schedule and procedures.

Heavy Duty Transmission Filters

Contaminants can enter your transmission fluid system in the manufacturing process. They can also enter the transmission through the vent, or through the dipstick and fill tube during fluid level checking/filling. Most of the time, however, contaminants are the result of normal wear. These contaminants consist of metal chips and flakes from gears and bushings and fine fibrous material from clutch facings.

WIX transmission filters protect transmissions against contaminants in the transmission fluid system. Proper filtration helps improve transmission life by minimizing wear and preventing sticking and scoring of sensitive shift control valves. In the event of a part failure, the filter also guards against secondary damage to other parts and thus helps to minimize repair costs.

AquaChek Filters are designed to eliminate water from compressed air systems. Each filter has an innovative molecular bonding polymer that traps water – up to 28 times the weight of the filter media itself, and traps particulates down to .5 micron. From the point of contact, the polymer forms a molecular bond with the water and won’t release it. Why is there water in compressed air systems? When air is compressed, moisture in the air concentrates to the point where the water starts condensing and turns into free water. This is the single largest cause of air tool and equipment failure.

Most compressor packages don’t include equipment to minimize moisture. Even compressors with drying solutions fail to completely prevent the buildup of water vapor. In order to control free water, water vapor must be controlled. And because water vapor is always present in the air, moisture control filtration is always needed.

The WIX industrial filter line is structured to deliver the utmost in performance and coverage with more than 8,000 product numbers available for hydraulic and fluid power system applications. And, Wix's compressed air and gas filters are a perfect complement to WIX Industrial Line and have been engineered to meet the special high-performance needs and physical requirements of the air and gas industry.
