Filters For Railways

Parker dh Railway Air Treatment Units

The Parker domnick hunter Air Treatment Units (ATU) are compressed air railway dryers fitted with associated filtration. Designed to remove bulk oil, oil aerosols, bulk water, dirt particles and water vapour from railway industry compressed air systems, providing the highest quality compressed air to applications which depend upon clean dry air for their reliable operation. As the patented design is modular in construction, the ATU can be designed to meet the specific dewpoint requirements for the application at the specified worst case operating parameters.

This filter type utilises a very high efficiency coalescing element comprising of several layers of very fine borosilicate glass micro-fibre which captures dirt particles down to 0.01 micron in size and removes oil aerosols down to 0.01 mg/m3 @ 20°C (68°F). Coalesced liquid condensate collects in the base of the filter housing where it is automatically removed from the system by a solenoid operated / timed drain valve.
