Activated Carbon Filters

The Activated Carbon Filter system are used for the purification of compressed air and in particular to remove all the traces of oil in gaseous form. The air purification process is carried out in two separate filtration stages. The first stage consists of the Siemag Micro Coalescor which will reduce the liquid oil content in the air down to 0.01 mg/m3 (at 20°C), whilst removing all free water and dirt particles to 0.01 micron. Liquid contamination is drained away automatically. The specially developed filter cartridge located in the second stage contains a deep bed of activated carbon through which all the air must pass. This cartridge optimizes the air velocity and contact time which after filtration can result in oil levels down to 0.005 mg/m3. A long service life, typically twelve months (under tested conditions) is offers by this filter cartridge.
The filter housing are of all metal construction. Differential pressure gauges are available upon request. The filter combination employs both manual and automatic drain mechanisms for removal of liquid contamination.

A product specially designed for use within environments demanding critically clean air. This filter system is used extensively in the hygiene, medical & pharmaceutical Industries. This quality of air also meets international standards for breathing apparatus. An additional feature of this product is its capability to retain its efficiency at very low rates e.g. less than 1% of rated flow.

SELECTION AND USE:

Select the filter model depending on pressure and flow rate requirements. Install as close as possible to the application and replace filters elements when the pressure loss reaches 0.8 bar. For applications with a high degree of contamination the use of pre-filtration is recommended. These are available upon request. Best results are obtained when the filter system is used ar an operating temperature of 20°C or lower.
