MAINTENANCE

FILTER CARTRIDGE REPLACEMENT
The filter cartridge should be inspected
weekly or more often depending on usage
and the conditions of the air system in which
the Radex Airline Filter is installed. The filter
®
cartridge should be replaced after a period of
3 months based on a 40 hour week.
The filter cartridge must be replaced immedi-
ately if the following exist:
1. The presence of odour and or tastes in
the air being supplied to the respirator.
2. Presence of moisture at the outlet
fittings.
3. Large pressure drop across the filter.
DRAINING MOISTURE
Water will accumulate in the filter tank,
this should be drained by opening the ball
valve. This should be done each day. In very
humid climates or if there is large amounts
of water in the air supply it is recommended
to leave the ball valve partially open to
bleed the moisture. When fitted with auto
drain assembly 04-924, moisture will
automatically drain from the unit as particles
could cause blockages.
LID BOLTS, O-RINGS
The Radex Airline Filter lid bolts should
®
be checked to ensure that they are tight.
The lid bolts 04-920 should be replaced
when replacing the filter cartridge. The
recommended tightness for the lid bolts is
10 ft/lbs. Check the o-rings 04-919 and
replace if damaged.
REPLACING CARTRIDGE
1. Shut off the air supply to the Radex
Airline Filter and drain all air from the
body by opening the drain tap.
2. Remove the bolts from the lid and
separate the lid from the body.
3. Remove the cartridge and dispose in an
appropriate disposal area.
4. Clean the inside of the filter body to
remove any contaminants, do not clean
