SIKA-R...AS is a high
porous ASymmetrically designed metallic membrane. The thin layer giving
the filter its performance is coated on a coarser SIKA-R support
structure. Metal membranes can be manufactured to all dimensions from
SIKA-R...AX and SIKA-R...IS. The membrane's two functions, strength and
particle retention, are separated from each other – leading to a new
type of filter. The coarser support material renders the mechanical
stability without increasing the pressure drop of the filter system
considerably. This filter-active membrane was developed as a surface
filter and allows pore sizes from 0.1 µm to 3 µm. The thin coating is
connected to the support structure by sintering.
SIKA-R...AS qualities differ from the known properties of SIKA-R
materials in the following points:
 |
up to 4 times higher
flow rate |
 |
surface filter |
 |
improved backflushing
performance |
 |
longer service life in
