Diesel Particulate Filters

Why we are the brand to trust in the aftermarket.

Klarius produces a huge range of premium DPFs for vehicles old and new, with a focus on providing optimum solutions to fit specific makes, models and production years. Every component is supplied with a 2 year warranty and a ‘Fit First Time’ guarantee as standard.

The entire Klarius Products DPF range is type-approved to EU legislative standards, certificated by an independent regulator, and each DPF carries a unique type-approval number to prove this certification. All DPFs are fit tested to applicable vehicles, as well as being certified by organisations such as the VCA and TÜV. This ensures a reliable product that guarantees vehicle performance and fuel efficiency capabilities are preserved.

What is a DPF?

An incredibly important component for ensuring the emissions compliance of diesel vehicles, DPFs collect and process harmful soot particles produced by diesel engines. Constructed with a metal casing containing an internal monolith filter, DPFs act as a filter, capturing large soot particles so they are not released into the atmosphere.

Once the captured soot in the monolith reaches a level where it starts to reduce gas-flow through the device, a regeneration cycle is triggered. This cycle takes the form of a controlled burn-off that happens inside the device during long journeys. Larger soot particles are burnt to emit less harmful gases and fine ash which remains stored inside the DPF monolith. Over time ash will build-up and the DPF will eventually require replacing.

What is the law on DPFs?

Diesel vehicles requiring DPFs that are caught on public roads without one can be fined up to £1,000 for a car and £2,500 for a commercial vehicle. Its absence (which applies even if just the internal monolith has been removed) will be easy to spot by most motorists due to the black smoke exiting the vehicle.

With regards to MOT testing, as of February 2014, the test now incorporates a DPF check for diesel vehicles if the component was fitted from new. A lack of DPF can cause a test failure, resulting in vehicle owners having to find a quality replacement before hitting the road again.

Why do I need a type-approved DPF?

An OEM equivalent aftermarket DPF provides the user with high reliability if properly installed on a vehicle, but many inferior replacements will feature a reduction in monolith size by up to 50%.

These DPFs fill with soot quickly during use, requiring more frequent regeneration processes and increasing the chance of blockage, either with soot, due to frequent short trips, or ash due to a reduced monolith size. Both scenarios result in more frequent replacement and increased costs to motorists.

A Klarius DPF will function efficiently with minimal servicing. Rather than taking the risk of fines and the added inconvenience of your car being removed from the road, spending a bit extra on a quality aftermarket replacement is more environmentally sensitive and less risky than the alternative of DPF removal or an inferior component.
