'J' Option: EPDM
For fully compatible liquids (liquids which do
not soften, swell or attack the filter assembly).
For other liquids, please contact Pall.
The maximum allowable time for continuous
use in an aqueous service is 120 days.
Maximum allowable pressure:
0.19Mpa / 2 bar g / 30 psig

30°C / 86°F
Minimum allowable temperature:
5°C / 41°F
Operation outside the above limits and with
fluids incompatible with the materials of
construction may cause a fracture resulting
in personal injury and/or damage to
the equipment.
The following procedures are required to
assemble and install the Pall EZ In-Line
capsule. They should be thoroughly read as
they contain valuable information gained by
extensive experience. It is very important that
all instructions are carefully followed. If some
of the procedures do not suit your needs,
please consult Pall or your local distributor
before finalising your system.
2. STORAGE
(a) Store the filter capsule in clean, dry
conditions and whenever practical in the
box as delivered.
(b) DO NOT remove from its protective bag
until ready for use.

STATIC ELECTRICITY

WARNING!
USE OF THE EZ IN LINE CAPSULE WITH
LOW CONDUCTIVITY LIQUIDS CAN
RESULT IN THE ACCUMULATION OF A
STATIC CHARGE. THIS HAZARD WILL
BE INTERMITTENT AND WILL DEPEND
ON ATMOSPHERE CONDITIONS SUCH
AS HUMIDITY.
For guidance, low conductivity liquids may be
considered as those with a conductivity below
50pS/m. Aqueous solutions have a
conductivity above 50pS/m but care should
always be taken to prevent the likelihood of
static damage.
When static charge is accumulated, both the
filter capsule and the liquid leaving the
assembly will retain the charge. Pipework
upstream and downstream of the filter
assembly should be of conductive materials
and grounded.
Care should be taken when removing the
filter capsule from pipework to avoid static
discharge. It may be necessary to allow
time for the static charge to dissipate
before removal.
Internal static discharge within a charged
filter capsule may result in damage to the
filter media.
For further details please contact Pall.
