Total Solutions Partner

FlowMax DPF prides itself in being more than just a DPF cleaning service. We provide a diverse range of expertise, experience and proven technology designed to support our services and product offerings to better serve the diesel emissions client.


No other system on your vehicle will have as significant of an impact on your bottom line as the diesel emissions system on a 2007 or newer vehicle. Poorly maintained emissions systems lead to reduced fuel economy, engine performance, durability and power, increased repair expenses and unscheduled downtime. It's all about the bottom line.


FlowMax DPF provides "State of the Art" DPF cleaning services, DPF failure analysis and a diesel emissions fleet maintenance program to ensure that our clients reduce expenses and downtime to maximize profits.

Diesel Emissions Fleet Management

It is critical to incorporate the entire diesel emissions system into your overall maintenance program. It’s all about profitability and the negative impact that a poorly maintained emissions system and DPF has on fuel economy, reduced engine performance and unplanned maintenance expenses.


A successful diesel emissions fleet management program will incorporate fleet emissions data, driver/employee training, fuel handling and management strategies, idle reduction strategies and ensuring that your maintenance intervals and practises are compatible with current diesel emissions control devices. There are several more initiatives that contribute to the profitability of a fleet equipped with diesel emissions control systems. Filter cleaning is always a critical step, but should be regarded as a component to a much broader strategy.


Count on FlowMax DPF as your diesel emissions fleet management partner.

DPF Failure Analysis

It is expensive and counterproductive to replace a damaged or failed DPF without identifying and correcting the root cause of the original failure.


FlowMax DPF has the expertise, experience and technical resources available to provide effective and accurate DPF failure analysis and diagnostic services to identify and provide proactive solutions to reduce unnecessary  maintenance expenses and recommend strategies to prevent them from reoccurring.

DPF Cleaning | Reconditioning Services

All 2007 and newer On-Road heavy trucks are equipped with a diesel particulate filter to reduce exhaust particulate matter (soot) and ash by at least 85%. Trucks newer than 2010 are also equipped with an additional system such as SCR (Selective Catalyst Reduction) which requires the use of DEF (Diesel Emissions Fluid) to control Nitrogen Oxides (NOx). These EPA regulations now require all new On-Road as well as Off-Road construction, farm equipment and stationary generators to be equipped with DPF and SCR technology.


“A clean DPF ensures optimum engine power, performance and fuel economy reducing the risk of unplanned maintenance expenses and down time”

Recommended DPF service intervals vary greatly between manufacturers. Ultimately how frequently your DPF needs to be cleaned depends on several variables. It’s important to note that in recent years many OEM’s have significantly reduced the recommended mileage and hours of service between DPF cleanings. Engine RPM, engine load, exhaust temperatures, duty cycle, idle time, fuel quality, engine oil quality, emissions after treatment systems, overall engine condition and maintenance procedures all have a tremendous influence on when and how frequently a DPF needs to be serviced.

FlowMax DPF’s “State Of The Art” DPF cleaning process offers the best value for your $$$$ by outperforming DPF cleaning efficiency and customer service standards offered by most dealers and independent DPF cleaning contractors.


Inspection, Testing & Quality Control Standards

The FlowMax DPF cleaning process incorporates a rigorous inspection and data recording process tracking each DPF by serial number throughout each stage of the cleaning process. Baseline and historical data is used to track and assess the lifecycle and maintenance requirements for each DPF. Each DPF is shipped with a data report to the customer for their fleet management records.

Pneumatic Cleaning Technology

Basic DPF cleaning begins with a pneumatic cleaning process in our specialized pneumatic cleaning system which uses large volumes of highly compressed air directed into each cell from both directions to remove PM (particulate matter) and residual ash.


It’s important to note that particulate matter does not load uniformly throughout or across the face of a DPF. FlowMax DPF’s pneumatic cleaning process identifies and removes PM (particulate matter) and micro-pore restrictions from these high soot load zones ensuring a cleaner more flow efficient DPF.

Thermal Cleaning Technology

After undergoing the pneumatic cleaning process the DPF is once again tested and the results compared to baseline and historical data to determine whether any unburned soot and/or ash remains inside the DPF. If the flow restriction and other data are unacceptable the DPF is then placed into a thermal regeneration oven between 8 to 12 hours. The temperature cycle is pre programmed for individual conditions and type of DPF material to burn off any remaining hydrocarbon based PM (particulate matter) and fracture the bond between the substrate walls and the remaining ash.

The DPF is then removed from the thermal regenerator and once again put through the basic/pneumatic cleaning process to remove all remaining ash from the DPF. Filters that are heavily loaded with PM (particulate matter) may need to have the thermal regeneration process repeated a couple of times to restore the DPF to serviceable condition.

Oil & Coolant Contaminated DPF Recovery

Mechanical failure of a turbocharger, fuel injectors, a head gasket, or an EGR system, can cause excessive amounts of engine oil and or coolant to saturate the DOC ( Diesel Oxidation Catalyst) and DPF ( Diesel Particulate Filter).  Filters that are heavily loaded with PM ( Particulate Matter) , have become face plugged, or are soaked with oil and/or coolant, can be restored to serviceable conditions if exposed to the correct regeneration process and cycles in the regeneration oven. Most DPF service providers will often refuse to clean an oil saturated DPF or if attempted can destroy otherwise salvageable DPFs due to inexperience. FlowMax DPF specializes in recovering oil and coolant contaminated filters and restoring them back to serviceable standards without the risk of damaging the DPF or poisoning catalyst coatings.
