TMC task force looking at reusable filters


ATA’s Technology & Maintenance Council (TMC) has charged a task force with qualifying questions for the evaluation of cleanable and reusable filtration devices.

An increasing number of fleets and independent operators are looking at reusable or cleanable filters as a way of saving on maintenance costs. Filter outlays can amount to hundreds of thousands of dollars annually for some fleets. Although initially more expensive that standard filters, some reusable filters can survive the lifespan of the most durable high-speed diesel engines.

“Reusable filters are not giant sellers in the marketplace yet, but sales are likely to continue growing in the future, particularly if the OEMs and the aftermarket in general are willing to acknowledge their use as a recommended practice,” says Karl Dedolph, President of D3 Consulting, an independent group that provides integrated sales and marketing strategies to the auto, light truck, heavy-duty trucking as well as performance and off-road transportation categories in filtration and lubrication. Dedolph also serves as chairman of the task force. “The fleets are the big category, and that’s what our task force is trying to look at.”

“The main challenges that the task force addresses are economic, Dedolph says.

“The potential benefits of heavy-duty truckers using reusable/cleanable filters are certainly within that scope, including savings on filter costs, inventory costs and disposal costs.”

Dedolph points out that while quality reusable filters do seem to meet the economic criteria, there are some other important standards that reusable filters must meet, including OEM standards for efficiency, capacity and flow.

Looking for capacity

Of these three measures, capacity is among the most prominent in the eyes of the TMC task force. If a reusable filter does not provide the necessary capacity over the PM duration, the other economic and performance benefits could be in question.

The military and severe-duty vehicles, such as those that operate in open pit mining and quarry operations, have used these filters successfully.

The cleanable, reusable filter technology was first developed, tested, and manufactured by Parker Hannifin’s Racor Division almost a decade before they turned the technology over to Filtration Technology Group (FTG), a full-service Racor distributor, which has independently manufactured it for the past several years.

FTG is a manufacturer of custom lubrication filters and a global supplier of quality filters and fittings that offers full-flow, cleanable, reusable filters that are designed to last the life of the engine or beyond.

One of the reasons the FTG line draws attention among washable filters is because FTG purchased the Racor product, which is widely considered the top tier product in the marketplace.

As far as potential savings are concerned, FTG has cited cases where a fleet of 300 Class 8 heavy-duty trucks has tracked its use of conventional filters for a 10-year period and calculated expenditures of $350,000. There is evidence that converting to reusable filters would save the same fleet over a thousand dollars per vehicle.

“You could pick almost any number,” Dedoph cautions. “It depends on the fleet, the age of the vehicle, PM interval, and so on. Perhaps most important in many cases is the operating environment. All on-board filters are important, but perhaps where the vehicle is driven and duty cycle creates the best correlation to results and benefits for cleanable and washable filters.”

In some ways Diesel Particulate Filters (DPF) make the best case for reusable filters, Dedoph says. The ceramic core used today is upwards of $4,000 to replace, Dedolph adds, and will sometimes crack or chip or burn too hot and have to be replaced. Others don’t withstand the cleaning mechanism.

“Considering those factors, a stainless steel, reusable DPF sounds like a pretty good answer,” he says.
