Specific Product Precautions 1
Be sure to read this before handling. Refer to back pages 1 and 2 for Safety Instructions,
and “Precautions for Handling Pneumatic Devices” (M-03-E3A) for Common Precautions.
Warning
1. Hold the female thread side and tighten to the rec-
ommended torque when screwing in the piping ma-
terial.
Insufficient tightening torque may cause loosening or defec-
tive sealing. Over-tightening torque may damage the thread
etc. If it is tightened without holding the female thread side,
excessive force will be directly applied to the piping bracket
resulting in a product failure.
2. Do not apply torsional moment or bending moment
(except the product's own weight) to the bracket. It
may damage the bracket. Support external piping
separately.
3. Inflexible piping such as steel piping tends to be
affected by spread of excessive moment load or vi-
bration from the piping side. Lay flexible tubing be-
tween the steel pipe and the product to prevent
such effects.
1. Design the layout so that the mist separator should
be installed in an area that is less susceptible to
pulsations.
The element could be damaged if a difference between the
inlet pressure and the outlet pressure exceeds 0.1 MPa.
2. Be careful of dust generation by the pneumatic
equipment mounted on the outlet side.
When installing pneumatic equipment on the outlet side of the
AM series, dust particles may come off from outlet equip-
ment, which will lower the cleanliness of compressed air. Con-
sider this impact upon the cleanliness of compressed air when
installing pneumatic equipment on the outlet side.
3. About when to use N.C. auto drain and N.O. auto
drain.
When using the AFF2C to 22C, 37B, 75B, AM150C to
550C, 650, 850 with normally open (N.O.) auto drain, air may
ceaselessly blow out of the drain discharge area when an air
compressor with a small air discharge volume is used since
the valve does not close unless the air pressure is 0.1 MPa or
higher. Therefore, when using a compressor for 3.7 kW or
less, make sure to use the normally closed (N.C.) auto drain.
The minimum operating pressure is 0.15 MPa even with N.C.
auto drain.
4. Use a tubing with proper size and length for drain
piping of auto drain.
When using the AFF2C to 22C, 37B, AM150C to 550C, 650
with auto drain:
Normally closed (N.C.)
Normally open (N.O.)
When using the AFF75B and AM850 with auto drain:
Normally open (N.O.): Use tubing I.D. 9 mm or more and
keep the whole length within 2.8 m.
5. Provide a design that prevents back pressure and
back flow.
Back pressure or back flow may damage an element.
6. Keep the certificate of Class 2 Pressure Vessel in a
safe place.
Products below are subject to Class 2 Pressure Vessel Act.
Certificate will be sent in 2 to 4 weeks later after the shipment
of the product.
