danger in case of a possible failure.)
Do not handle the product or remove pipes and devices until confirming safety.
•Inspect and service the machine and devices after confirming the safety of the entire system.
Also, turn off the energy source (air supply or water supply) and power to the relevant facility.
Release compressed air and fluid from the system and use extreme care to avoid water or
electric leakage.
•Since there may be hot or live parts even after operation has stopped, use extreme care when
handling the product or removing pipes and devices.
•When starting or restarting a machine or device that incorporates pneumatic components, make

1.1 Environment
WARNING
Do not use the product in an atmosphere where sodium hypochlorite, synthetic oil, organic
solvent, chemicals, cutting oil, screw lock agent, leak detection agent, hot water, or other
hazardous factors are present or in a place where they may adhere to the product.
Deterioration may occur since the plastic bowl is made of polyamide.
Avoid using the product if compressed air contains chemicals, in an atmosphere where
chemicals are present, or in a place where chemicals may adhere.
When used in the above environment, the plastic bowl may become damaged and this may lead to
accidents.
For more information about the chemical resistance of the plastic bowl, refer to the table "Chemical
resistance of plastic".
Prevent the generated ozone from passing through the filter.
Deterioration of the filter element may occur. Use extreme care when using the product in
combination with equipment which generates ozone (such as an ionizer).
CAUTION
Observe the following precautions regarding the ambient environment.
•Do not use the product where there is direct irradiation of ultraviolet rays.
•Avoid installing the product where it is exposed to direct sunlight.
•Avoid installing the product where it is subject to vibrations and shocks.
Install an air dryer, an air filter, and an oil mist filter on the primary side to remove moisture
and oil.
Make sure that substances such as chlorine do not become mixed with the compressed air
when using a water lubricated type compressor circuit.
Install an air dryer and a drain separator before the air filter if there is a large amount of
drainage.
The odor removal filter does not remove drainage.An excessive amount of drainage from the
compressor may cause the air to become hot and highly humid and this may lead to lower
durability or corrosion of the product.

CAUTION
Fully flush and clean the pipes before use.
Residual dust or foreign matter in a pipe may cause operation fault.
Connect the pipes correctly according to the direction of flow by checking the direction of the
arrow.
Prevent foreign matters from entering the pipes while piping and connecting the fitting.
Be careful not to allow cutting chips from the piping screw and seal material from entering the
pipes while piping and connecting the fitting.
Residual dust or foreign matter in a pipe may cause lower performance of the product.
Tighten the pipes with the appropriate tightening torque.
Do not subject the body and the pipes to a bending moment that is due to pipe loads.
Firmly secure and install the product with the specified bracket, a stand, or a pipe support.
Do not apply high pressure suddenly when supplying compressed air for the first time after
connecting the pipes/tubes.
Sudden introduction of highly-pressurized air may cause the tubes to become disconnected and
jump around and an accident may occur.

Pipe cleaning
Before piping, blow air into the pipes to clean the interior and to remove cutting chips and foreign
matters.
Seal material
Apply a seal tape or seal material to the screw threads leaving two or more threads at the pipe end
uncovered or uncoated. If the pipe end is fully covered or coated, a shred of seal tape or residue of seal
material may enter inside of the pipes or device and cause a failure.
When using a seal tape, wind it around the screw threads in the direction opposite from the screw
threads and press it down with your fingers to attach it firmly.
When using a liquid seal material, be careful not to apply it to resin parts. The resin parts can become
damaged and this may lead to a failure or malfunction.
Also, do not apply seal material to the internal threads.
Pipe screwing torque
Do not apply excessive torque to the body and the pipes when piping.

2. USAGE
WARNING
Use the product within the specifications.
Ventilate sufficiently when using the product with nitrogen gas (N2) or carbon dioxide (CO2).
Do not use the product for medical purposes or in any equipment or circuit that concerns
human life.
The product is designed for industrial use.
CAUTION
Check the working circuit and the working fluid.
Do not subject the product to vibration, impact, or other external forces such as those caused
by swinging tubes.
Use the product within the maximum processing flow rate.
Use the product within the maximum working pressure and differential pressure resistance.
Use the product so that the pressure difference between the IN side and the OUT side does
not exceed 0.1 MPa.
•This product is manufactured and packaged in an environment where particles are managed
and monitored but suppression of bacterial adhesion and generation is not considered.
•The product itself is not subjected to any special sterilization/bacteria-removing treatment
(such as autoclave sterilization).
•The odor removal filter does not have antibacterial/bacteria-removing function.
•The odor removal filter adsorbs and removes oil vapor contained in the compressed air
(nitrogen gas and carbon dioxide). Activated carbon absorbs certain substances easily and
certain substances not so easily. Not all odors can be adsorbed and removed.
•The product cannot be used as an absolute filter since it does not provide absolute filtration.
•The secondary oil concentration given in the catalog is the actual value determined under our
specified conditions with an oil mist filter (M type of M Series) installed on the primary side.

Performance degradation may occur if the filter element is clogged. Make sure your hands are
clean when attaching the new element.
When replacing the element, make sure not to let bacteria, dusts, and foreign matters that
have adhered on the primary side flow into the secondary side.
Do not hold the filter paper when attaching or removing the filter element.
The product may become damaged or may not be able to exercise its full performance.
Do not use alcohol to disinfect or clean the product.
Deterioration or damage of the plastic parts may occur.
Do not modify the product.
3.1 Daily Inspection
•Thoroughly read and understand this Instruction Manual before maintenance and inspection.
•Check that the product operates properly before starting use.
