Handling instructions and Precautions (FRZB Filter Regulators)
Filter regulator
(With water and fluids removal functions)
●
Installing provided options
1.
Be sure to release any pressure in the system before attaching
(or removing) the various pressure gauges.
2.
When installing the various types of pressure gauges, always
apply the wrench on the square or hexagonal part of the piping
connections.
3.
Use a tightening torque of 2.21 to 3.69 ft•lbf if the various pres
-
sure gauges are mounted on the NPT1/8 or NPT1/4 pressure
port plate.
4.
There is a stopper on the female thread of the NPT1/4 and the
NPT1/8 pressure port plates.
Note
Gripping the body of the various pressure gauges to tighten
them may damage component parts.
Note
If torque exceeding the specifications is applied, it may dam-
age component parts. Also, if torque below the specifications
is used, the screw may come loose and cause an air leak.
Note
Further tightening after the stopper has been reached may
damage component parts.
Note
The service life of the element varies depending on the
quality of air supplied to the IN port (primary) side. If there
is a lot of foreign matter in the air supply to the IN port (pri-
mary) side, install a pre-filter on the IN port (primary) side
or change the element more often. As a guideline, change
the element after a year of use.

●
Replacing the pressure port plate, knob, and mounting ring
1.
When replacing the pressure port plate, refer to "Replacing the
□
1.181 in. integrated pressure gauge and pressure port plate"
on page
.
2.
When replacing the knob and mounting ring, refer to
"Removing the knob" and "Attaching the knob" on page
.
●
Replacing the seal kit, element, and bowl assembly
1.
To replace the seal kit, element, and bowl assembly, remove
the filter regulator and do the work on a work table.
2.
The o-rings and other sealing materials (except for the dia-
phragm) of the filter regulator are coated with grease.
3.
Contact your nearest Koganei sales office or overseas depart-
ment if you are considering re-coating the o-rings and other
parts with grease.
Recommended grease: Lithium Soap based No. 2 or equivalent
4.
Periodically replace the element in the filter regulator.
Note
They have different internal component parts, so their
specifications do not match.
Note
Cracks, scratches, or other deterioration can cause the
bowl to break.
Note
Always assemble the component parts correctly.
5.
It is not possible to combine a bowl assembly for an FRZB filter
regulator (with water and fluids removal function) with FRZ
series filter regulators (without water and fluids removal func-
tion).
6.
Do periodic inspections to look for cracks, scratches, or other
deterioration in the clear plastic part of the bowl assembly. If
you detect any cracks, scratches, or other deterioration, stop
using the regulator and replace the bowl assembly with a new
one.
7.
Replace the bowl assembly with a new one if it becomes dirty
or the transparency is significantly reduced. To wash the bowl,
use diluted household neutral cleaner to wash it and then rinse
it off with water.
See page
for details about the chemical resistance of the
bowl material.
8.
When replacing the seal kit, element, and bowl assembly, be
careful not to lose component parts.
9.
Refer to page
when replacing the seal kit, element, and bowl
assembly.
