Choosing the Right AirDog® Fuel Filters for Your Diesel Tank

One of the things that makes AirDog® fuel filtration systems so effective is that they are customized for specific applications. It’s important to select the right filters for your specific diesel engine, whether you are operating a commercial heavy truck or a pickup truck. We make it easy to identify the correct fuel filters for your vehicle so there is no question about which is right for your needs.

We encourage users of AirDog® fuel filters to always keep a spare set of fuel filters when out on the road. Otherwise, a clogged filter could result in unwanted downtime and calling in expensive mechanical help—when all you really need is another set of filters to screw on.

Understanding AirDog® Filter Options

We try to make it as easy as possible to know which fuel filter is right for a diesel engine. Our semi-truck filters are categorized in the 200s and our pickup truck filters are categorized in the 100s. A filter in the 200s is only appropriate for heavy-duty commercial vehicles, while a filter in the 100s is only appropriate for pickup trucks.

You can easily tell if the product is a fuel filter or a water separator by the letters at the beginning of the filter name: FF for fuel filter, WS for water separator.

Let’s take a closer look at our filter categories so you know how to know which filter to buy for your vehicle.  

Commercial Medium- and Heavy-Duty Trucks (Class 4-8)

• FF200-MG-6: This AirDog® fuel filter is performance-matched to the AirDog® FPII and Champ systems. Using microglass media, it filters down to 6 microns while allowing a freer flow of fuel than traditional cellulose filters. This filter can typically be operated for up to 40,000 miles as long as no algae or other serious contaminants are present.
• WS200-HS: This water separator/pre-filter is performance-matched to get the most out of the AirDog®FPII system. It should be changed when changing the fuel filter. It features high-performance Hydrosorb media, which allows it to remove water and large particulates with excellent efficiency.

It’s always a good idea to carry an extra set of fuel filters and water separators when operating heavy trucks. We offer multi-packs at cost savings to ensure you always have a spare set in case of clogs while on the road.

Industrial Applications, Marine, and Light Duty Trucks

• FF100-2: Manufactured with high-quality Stratopore media, this 2-micron fuel filter is well-suited to get the most out of the smaller AirDog® Heavy Duty and Industrial Diesel Fuel Systems for industrial, marine, and light duty truck applications.
• WS100: This water separator/pre-filter is performance-matched to get the most out of the AirDog® FPII Diesel Fuel Systems. The filter is serviceable and simply requires draining at regular intervals.

Remember, our 200-level filters are for heavy-duty truck and other high-demand applications, and our 100-level filters are for light-duty pickup trucks and other applications using the 3” diameter filters .

The Importance of Spare Filters

Any experienced commercial driver can tell you how expensive it is to call a roadside mechanic to help with a heavy-duty truck. It’s a frustrating reality that even the best fuel filters can clog during operation. It’s also practical to understand that filters can reach their operational lifespan at inconvenient times, like when you are hundreds of miles from the nearest parts store. That’s why carrying spare filters is smart both economically and practically.

Even if you are in a town, there is no guarantee that you can find a store that carries AirDog® filters. While you can use other filter brands in a pinch—including on AirDog® fuel filter systems—it’s not ideal. Only AirDog® filters offer the high level of performance you expect from your system and require for your vehicle’s longevity and performance.

If you are an AirDog® user, you can take advantage of our filter pack specials, where you can purchase multiple filters in a single package at a discounted rate. That way, you will always have spares and you can save money in the process.

Finding Replacement Filters

In a perfect world, you’d always have a spare set of AirDog® filters to replace your existing filters when you need them. But the reality is that there may be times when you just don’t have the option of getting an AirDog® filter. You might need a fuel filter right now and only have access to major brands of filters.

Crossover Filter Options

We want AirDog® to be as useful as possible for our customers, which is why we ensure that it is compatible with many of the major fuel filter brands. Keep in mind that these filters are not likely to provide the high level of performance that you get from our filters. If you have an AirDog® system installed, you definitely want to get our filters installed when you can. But until then, you can pick from a variety of major brands, including:

• Fleetguard
• Baldwin
• Luberfiner
• Wix
• Napa
• Cim-Tek
• Hastings
• Donaldson

Conclusion

AirDog® fuel filtration systems are some of the best you will find for heavy-duty diesel and light-duty pickup truck applications. While we are extremely proud of our products, we also believe that providing the best customer experience and support is what makes us a company that owners and operators can trust with their valuable machinery.

We do our best to make picking the right fuel filters in diesel vehicles as easy as possible. You can quickly identify the right filters for your vehicle by the filter name. Filters in the 200s are 3.75” diameter cans for heavy-duty commercial trucks, while filters in the 100s are 3.0” diameter cans for light-duty pickup trucks and industrial applications. FF indicates a fuel filter, while WS indicates a water separator.

It’s important to keep spare filters on hand, especially if you are on the road, so you don’t have to pay for an expensive mechanic visit if your filter clogs. Hopefully, you have some AirDog® filters on hand. But if you don’t, you can always reference our crossover list to find major brands of filters that will work with our filtration systems.
