Diesel Exhaust Filters

Micro Fresh Filters are suppliers and filter manufacturers of diesel exhaust filters for mining, underground coalmine and confined space applications.

About the DA 100 series diesel exhaust filter

The DA diesel exhaust filter range was developed specifically for use in the underground coal mining industry 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. This filter has the added safeguard of being non-flammable to 960°C (Tested to Australian Standard AS 2420) making it the ideal choice in the explosive atmosphere of an underground coalmine.

The carcinogenic properties of Diesel Particulate Matter (DPM) are well documented. DA filter can capture the hazardous sub-micron particles down to 0.3 micron in size. Combine this with being non-flammable, unaffected by exposure to water and low engine backpressure so as not to affect the efficient operation of the diesel engine. The DA is the only filter that offers all these features to give you cleaner air and improved working conditions.

Applications:

The DA exhaust filter is designed for use on diesel engines where either a wet or dry cooled exhaust system is fitted.

Underground coalmines
The DA filter series was originally developed for use in the underground coal mining industry where wet scrubber exhaust cooling systems are mandatory to guard against the risk of fire and explosion. The filter operates at temperatures below 100°C and its non-flammable qualities (will not burn at 960°C) ensure it remains safe even if it is accidentally exposed to excessive temperatures.

Confined space operations
Micro Fresh Filters engineers have designed and developed a unique compact dry exhaust heat exchanger that reduces the exhaust gas temperature to below 100ºC and enables the DA 100 filter to be fitted on all diesel powered equipment operating in enclosed or confined spaces. There are many applications such as warehouses, ship's holds, metalliferous mines and emergency power generators to name just a few.
