Learn why Freudenberg are the leaders in cabin air filtration!

Evolution of the Freudenberg cabin air filter

With the invention of the first cabin air filter in 1989, Freudenberg Filtration Technologies set new standards in health protection and safety within vehicles. To this day, our customers value us as a dependable innovation partner in the development of first-class cabin air filters for the automotive and mining industry. With our years of expertise, we have the ideal foundation for producing filter media of the upmost highest quality.

Reliable high-performance filter for mining use

Freudenberg Filtration Technologies has been a leading provider of filter solutions for mining since the early 1990s. We are very familiar with the extreme conditions faced by miners in the field, and we know how our microfresh filter solutions can contribute to optimal protection of the workers above and below ground.

Freudenberg Filtration Technologies recognise this and test all our Diesel Particulate Filter technologies for both mass and nanoparticle number reduction performance.

Freudenberg Filtration Technologies microfresh® Diesel Exhaust Filters offer the highest level of nanoparticle protection available.

Developed specifically for use in the underground coal mining where miners experience extreme working conditions. The DA filter will help remove diesel particulate from the exhaust of heavy diesel machinery operating underground and in confined spaces.

(Tested to Australian Standard AS 2420)non-flammable to 960°C making it the ideal choice in the explosive atmosphere of an underground coal mine.

Protect the health of your workforce.

Fine particulate dust emissions represent a signifcant health risk to personnel in the cabins of minesite vehicles.
Where standard "celluose" paper filter cartridges can be used to target larger road dusts and pollen, Freudenberg Filtration Technologies (F F T)’s advanced polymer filter cartridges target much smaller dust particles often found in mining. i.e. sub-micron Diesel Particulate Matter (DPM).

Freudenberg Filtration Technologies are the world leaders in the fitration of cabin air of on-road vehicles. Freudenberg Filtration Technologies CAF (Cabin Air Filters) can be found in just about all of the world’s leading vehicle OEM’s.
It is Freudenberg Filtration Technologies’s expertise in on-road emissions coupled with our skills in controlling ultra fine particles at their source (diesel exhaust flters) that has allowed us to develop Cabin Air Filtration "CAF" solutions for mining applications.

It is the smallest particle that causes the greatest damage to health and machine.

Freudenberg Filtration Technologies Cabin Air Filters for Diesel Particulate Control

• Further to just having a MERV filter rating based on the mass of dust being taken out, Freudenberg Filtration Technologies Cabin Air Filters (CAF) use electro-static filltration mechanisms that allow them to take out the nest Diesel Soot particles.
• MERV filter ratings alone cannot adequately designate CAF performance when it comes to Diesel Particulate, as the smallest soot particles have very little mass (but are the most prolific and dangerous).

Freudenberg Filtration Technologies have a number of MERV 16 (and other) rated Cabin Air Filters designed to t directly in to the OEM recirculating
air conditioning system of various mining vehicles including Loaders, Trucks, Ancillary and Light Vehicles.
Any OEM filter geometry can be accommodated.

Reduce mine site personnel exposure to Diesel Exhaust Emissions, a Group 1 Carcinogen listed by the World health Organisation IARC and recognised by Australian Cancer Council as Cancer Causing.
• Improve air quality underground and help improve the short and long term health of workers in enclosed space.
• Locally made for Australian mining conditions.
• Please contact us for further information on Freudenberg Mining Cabin Air Filters.


For the most OHS critical applications such as mining environments containing asbestos debres, Freudenberg Filtration Technologies manufacture HEPA rated fiters for aftermarket cabin air pressurisation system suppliers.

No matter where your operation is whether it be underground mining or enclosed confined space Operations Freudenberg Filtration Technologies have you breathing easier.
