SEFAR ® PHARMA fabrication
Sefar has established a specially
designed fabrication process to
meet the most critical needs of
the pharmaceutical industry. Sefar
fabrication sites producing
SEFAR ® PHARMA-Grade pro ducts
must implement defined GMP-
Guidelines in addition to the tight
quality control systems already in
place.
The guidelines contain directives
for:
– clean liness and traceablility of
all material, components and
supply items/accessories used
for fabrication
– manufacturing documentation
and work instructions
– quality control and final inspection
– employee training
– compliance and implementation
of these guidelines at the

fabrication plants
– packaging and labelling
Detailed work instructions specific
to SEFAR ® PHARMA-Grade products
ensure that the stringent
requirements of cleanliness, traceability,
overall quality and performance
are being met.
However the most important
change to classical fabrication is
the strict limitation of the selection
of usable fabrics and component
items/accessories.
– Only specifically designated
non-filtering component and
supply item/accessories needed
for manufacturing the product
are considered as suitable for
our Pharma products.
– All supply items/accessories
with pro duct contact are either
FDA compliant or have been
