Explaining DPFs & Catalytic Purifiers

What are Diesel Particulate Filters (DPFs)?

Diesel Particulate Filters (or DPF’s) are one of the solutions widely used in the industry to reduce emissions. Catalytic Purifiers are used to eliminate and changes the gases and vapours via a reaction within the catalyst to make them less harmful in the working environment. Diesel exhaust comes from engines burning diesel fuel. It is a complex mixture of gases, vapours, liquid aerosols and particulate substances. These substances are the products of combustion.

1. DOC (Diesel Oxidation Catalyst)

A DOC Purifier is a flow through a filter that contains precious metals to start the oxidation of hydrocarbons, carbon monoxide and unburned fuel and oil.

• Highly Durable Metallic Core
• Cost-Effective
• Low Maintenance
• Available as an add-on unit to an existing system
• Can be adapted to suit bespoke OEM applications

2. Partial DPF

It’s a flow-through metallic filter that removes over 60% of diesel particulate matter.

• Low Maintenance
• Low accumulation of soot particles.
• Available as an add-on unit to an existing system
• Can be adapted to suit bespoke OEM applications
• Almost no increase in backpressure.

3. Wall Flow DPF

It is a ceramic honeycomb blocked one end to trap diesel particulate matter over 99% allowing airflow only through ceramic walls.

• These DPFs are passive, requiring no active regeneration or fuel additives.
• Removes ultra-fine and nano particulates.
• These are customized to suit bespoke OEM application.
