The Flowtech Catalyst Combination filter is meticulously engineered to effectively lower emissions to meet the standards required across various applications.

This filter is popular for its low-maintenance features and is generally less restrictive, smaller and requires less maintenance than a DPF-Ceramic.

Utilising  Partial Filter Technology, these units are also known as Partial DPF’s

It is best suited for stationary engines like generators, fire pumps, or engines in multi-story buildings or confined spaces.

Technical Documentation

This Diesel Particulate Filter with Pre-Catalyst is a specialist combination designed to remove High levels of Carbon Monoxide (CO), Hydrocarbons (HC),  and high levels of Particulate Matter (PM) from Diesel exhaust systems.

These units utilise heat from the pre-catalyst to keep the DPF at its optimum operating temperature ensuring a longer life and superior performance.

• Generally installed on fixed engines such as hospital or CBD building standby generators
• Can be supplied with a custom heat blanket
• It can be designed for underground operation
• Ideally used in mining operations
• Regular cleaning is required due to a significant 99% reduction in Particulate Matter.
• Customisable to fit any engines
• The metallic catalyst and the cordierite DPF are suited for high-vibration loads such as moving vehicles 

Ceramic Diesel Particulate Filters are designed to remove High levels of Carbon Monoxide (CO), Hydrocarbons (HC), and High levels of Particulate Matter (PM) from Diesel exhaust systems. They do not remove Nitrous Oxides (NOx)

These require high operating temperatures, and more regular servicing and are generally larger diameters to allow sufficient gas flow.

The Flowtech Diesel Oxidation Catalysts, or DOCs, can be a lifesaver when it comes to reducing emissions from diesel engines and equipment. Whether you’re driving a heavy-duty vehicle, maintaining a fleet, or powering an industrial generator, DOCs specifically designed for types of diesel can help cut down on dangerous emissions.

Not only are they simple and cost-effective, but they’re also maintenance-free and effective at reducing Carbon Monoxide, Hydrocarbons, and Diesel Particulate Matter.

Applications of Diesel Oxidation Catalyst (DOC)

The DOC’s technology is constantly expanding thanks to its effectiveness when compared to other methods of emission reduction.

• It can be used in both new and existing diesel engines
• Industrial generators
• Mobile Equipments (such as MOPP) see an actual example

Advantages of Using Diesel Oxidation Catalyst (DOC)

• The highly durable metallic core
• Cost-effective
• Low maintenance (Back pressure is your guide)
• Available as an add-in unit to an existing system
• Can be adapted to suit bespoke OEM applications
• It can be incorporated into the Flowtech silencer

To reduce emissions without investing in costly engine upgrades. It’s also possible for DOCs to be installed alongside other control systems, such as particulate filters or exhaust after-treatment systems, to further reduce emissions.
