Filter Applications (EMEA)

Compressed Air for RoadheadersCompatible Products

NASH WITTIG has a compressor that is engineered for underground mining work. Installed directly behind the roadheader in the powertrain, our RO rotary vane compressor model ensure that the operation of roadheaders does not need to be interrupted for the purpose of extending compressed air lines. 

Methane Gas ExtractionCompatible Products

Methane gas accumulation in underground coal mining is dangerous. Explosions and resultant loss of life can and has occurred. NASH systems designed especially for this application are supplied to help prevent this dangerous condition.

Vacuum FiltrationCompatible Products

In this application, the moisture from the filtrate receiver of a vacuum filter is collected and fed back into the system. If a system upset occurs, such as the failure of the filtrate pump, slugs of liquid can carry over into the vacuum system. Soft solids from the filter can also enter the vacuum system. In both cases, the liquid and soft solids will not damage the liquid ring vacuum pump, improving the overall reliability of the vacuum filtration system. A variety of seal liquids compatible with the process vapors may be selected in order to minimize contamination of gases extracted during the filtration process.
