1. Filter cartridge
The particle filter is intended for filtering solid particles and solid decomposition products out of SF
6
gas.
Gaseous decomposition products can be adsorbed by a dry filter 3-376.
The filter cartridge is folded to a cylinder with star-shape section.
The result of this arrangement of the surface is a large filtration surface (0.12 m
2
/ 1.3 sq. f.), that makes
possible a long service life.
A retention rate of 100% is obtained from a particle size of 1.0 µm
2. Revision intervals
The exchange of the filter cartridge in the particle filter should be carried out together with the exchange
of the cartridge of the dry filter or when performing a revision of the compressor.
3. Exchange of the filter cartridge and disposal
Attention: Depressurize the particle filter before dismantling the filter cartridge.
Pay attention to the protective rules concerning the handling of SF
6
gas 1.
Unscrew the filtering cone
Remove the filter cartridge
Clean the interior space of the filter cone with a fibreless piece of cloth
S l i g h t l y grease the o-ring in the new filter cartridge and the o-ring in the filter cone as well as
the thread with a suitable sliding means
Push the new filter cartridge on the guide pipe in the screw cap (do not forget the compressing
spring!)
Screw in the filter cone until the stop
Attention: The particle filter must be evacuated before putting it into operation.
Attention: If the filter cartridge is left until disposal it has to be put into a plastic packing and
sealed tightly. Thus the decomposition products are no longer set free.
