FRZB Filter Regulator
For all FRZB Filter Regulators
●Selection
Look at the Handling Instructions and Precautions, Specifications, Various
Characteristics, Dimensions, and other technical materials for each product
to make the correct decision.
●Mounting (installation) direction, support, and securing
1. The products cannot be mounted (installed) if a bending moment or twist-
ing moment is applied to the product or piping.
2. Do not attach piping so that just one side is fixed as shown in the follow-
ing diagram. Support external piping separately.
Design and selection
Mounting (installation) and piping
Applying bending moment or twisting moment may damage
the product.
The muffler must be prepared by the user.
(In case of NPT thread specifications)
Operating the knob and the moment caused by the OUT (second-
ary) side pipes may damage the product's piping connections.

●Preventing contamination by foreign matter
1. Remove all foreign matter, such as metal chips, cutting oil, or dirt, from
inside pipes with compressed air blow (flushing) and thorough washing
before fitting the pipes.
2. Do not allow foreign matter, such as metal chips, or sealing tape from the
piping threads, to get into the pipes when installing the pipes and fittings.
●Maintenance space requirements
Assure there is sufficient space for maintenance inspections and mainte-
nance work.
See the dimension diagrams for each of the products regarding the mainte-
nance space.
●Attaching steel pipes and fittings
If steel pipes and fittings are attached to the threaded sections of the alumi-
num die-cast parts of the product, tighten them to the torque recommended
in our standards.
If a product is not securely fixed in place, it may fall over, be dropped,
or operate abnormally and cause an injury.
It there is not enough allowance for maintenance space, it is
impossible to remove the bowl assembly and replace the filter.
Also, it is impossible to do maintenance inspections so the equipment
may stop or the product may be damaged.
Tightening with excessive torque may damage the product or injure
workers or operators.
Use a tightening torque of 3.0 to 5.0 N•m [2.21 to 3.69 ft•lbf] if the
various pressure gauges are mounted on the 1/8 or 1/4 pressure port
plate.
Foreign matter entering the piping may damage the product or reduce
its performance and service life.
3. Use the brackets to install the products.
4. When mounting (installing) products, always make sure they are
secured and sufficiently supported.

If liquid sealant gets on the polycarbonate parts, it may damage them.
4. If you are using liquid sealant, do not get it on the polycarbonate parts
(the bowl of the filter regulator and the front cover of the pressure gauge).
3. Wrap the sealing tape in the direction as shown in the diagram below
leaving 1.5 to 2 threads uncovered. When using liquid sealant, apply a
suitable amount and in the same way leave 1.5 to 2 threads uncovered.
If the sealing tape or sealant gets on the lip of pipes or
fittings, bits of it may get into the pipes and cause air leaks.

4. Avoid piping that is rigid, such as steel piping, if vibrations are transmitted.
Use flexible tubes so that the product is not subject to the vibrations.
●Usable medium
1. Use clean air (filtered to below 40 μm) for the medium. Contact the near-
est Koganei sales office or overseas department if you are considering
using something other than clean air.
2. Avoid using air that contains too much moisture and/or fluid.
3. If air that contains moisture and/or fluids is used, or if it is possible that
they may be mixed in with the air being used, we recommend using the
iB-Cyclone to reliably remove moisture and fluids.
4. Do not use the product if the medium being used is prone to extreme pul-
sating or surging.
●Operating environment
1. Do not use the product in locations that are subject to direct sunlight
(ultraviolet rays); locations with high humidity and temperature, dust, salt,
or iron powder.
2. Cover the unit when using it in locations where it might be subject to
excessive dust, dripping water, dripping oil, etc.
3. Do not use the product in environments subject to external vibration or
impact.
Medium and operating environment
Contact a Koganei sales office or overseas department if you are
considering using something other than air.
Using air that contains too much moisture and/or fluids will cause the
product's functions to stop after a short period and will reduce the
product performance and service life.
If you use an iB-Cyclone, install an FRZ series filter regulator (without
water and fluids removal functions) on the secondary side.
Medium prone to extreme pulsating or surges will cause the product's
functions to stop after a short period and will reduce the product
performance and service life.
External vibrations or shocks may result in damage to component
parts.

●Medium and operating environment
1. The temperature of the medium and the ambient environment must be
within the range in the specifications.
2. Use a device, such as a freeze-type air dryer or after cooler, to lower the
dew-point temperature of the medium to below the ambient temperature
so condensation or frost does not occur in the secondary pipes.
3. Do not use medium in the product or use the product in an environment
that includes corrosive components such as organic solvents, phosphate
ester type hydraulic oil, sulfur dioxide, chlorine gas, freon gas, ozone,
acids, alkaline, etc.
4. The bowl and the front cover of the pressure gauge of the filter regulator
are polycarbonate. This product cannot be used in environments with the
gases and fluids in item 3, nor threadlocking adhesive, leak detection
fluid, hot water or where it may be exposed to them. This product also
cannot be used in direct ultra-violet light. See the catalog for details.
Using the product in an environment that is outside the specified
temperature or with medium that is outside the specified temperature
will cause the product's functions to stop after a short period and will
reduce the product performance and service life.
If condensation or frost forms in the product, it may get into the
secondary side.
Using the product in an environment or with medium that is specified
in the above item 3 will cause the product's functions to stop after a
short period and will reduce the product performance and service life.
Operation and maintenance inspections
●Method of use
Read the Handling Instructions and Precautions for each product for instruc-
tions on correct usage .
●Maintenance (maintenance inspection)
1. Performance and functions may decrease as the pneumatic equipment
ages. Always conduct daily inspections of the pneumatic equipment, and
confirm that all requisite system functions are satisfied, to prevent acci-
dents from happening.
2. Read the Handling Instructions and Precautions for instructions on main-
tenance and replacing maintenance parts .
3. The product must be disassembled and reassembled to use the seal kit.
The product is no longer under warranty if it is disassembled and
reassembled.
●Attaching and removing the bowl assembly
1. Be sure to release any pressure in the system before attaching (or remov-
ing) the bowl assembly.
2. Use the procedure shown in the upper right diagram to attach (or remove)
the bowl assembly.
3. Squeeze the guard button to attach (or remove) the bowl assembly.
If there is a bowl guard, it may fall off when you squeeze it.
4. When attaching or removing the bowl assembly, move it vertically so you
do not touch the internal component parts.
