Remanufacturing vs Bake and Blow
What is the best?
Before we can really sink our teeth into this question, we really need to understand what we’re talking about with regards to Remanufacturing a filter Vs the more commonly understood Bake and Blow.
DPF Remanufacture is somewhat of a gray area with regards to what it actually means, however across all people in the industry, there seem to be some commonalities.
Firstly, it includes Bake and Blow PLUS additional cleaning steps that are required to really loosen up that impacted ash. Some companies (like Penske) prefer the Aqueous/Ultrasonic methods, others prefer an Aqueous/pneumatic solution. However, all agree on those 2 points. It’s more than a bake and blow and it involves some sort of liquid solution.
So why is Aqueous Cleaning important?
Mass Density. That’s why!
If the ash is heavily impacted into the filter, it’s going to take something more than air (Super low density) at high speed to take it out.
We prefer the Mass density flow method whereby we’re using an aqueous pulsating system to clean the filters. This works extremely well as it allows a fine balance between maximal mass and Density flow, but without overpowering and potentially damaging the substrate.
Why should you care?
Really good question! At the moment, you pay a fair amount more for a remanufactured filter than one that is simply Baked and Blown.
It really all comes down to 2 major benefits.
1 – Less back pressure
This allows for better fuel economy, longer lasting DPF between cleaning/services/regenerations, longer turbocharger service life, less engine oil dilution.
2 – MUCH longer DPF service life
Lets say a DPF that is bake and blow has a residual value of 20% vs the residual value of 2%. It’s easy to see how that reman filter is going to stay on your truck for a whole lot longer.
BAKE & BLOW
DCARB and DPFcleaning.com have immediately ceased offering the Bake and Blow DPF cleaning process as a standalone service. DCARB support Daimler Trucks North America decision not to endorse stand-alone Heat & Air cleaning also known as Bake & Blow.
Cost-Benefit
Well if you’re paying upwards of $800 for a reman filter, there probably isn’t much. But here is where DCARB / DPF Cleaning can help.
We offer DPF remanufacturing at all our outlets for a fraction of the cost. AND – no exchange issues to deal with like Core Charges and not knowing the history of the filter you just purchased.
If this sounds like something you might be interested in, give our team a call on DCARB. We’d gladly talk you through the advantages and disadvantages of all of our services and give you a straightforward response to your questions.
