Selection
Warning
1. Do not select a model exceeding specifi cation ranges and
carefully consider the purpose of use, required specifi ca-
tions, and operating conditions, such as fl uid, pressure,
fl ow rate, nominal fi ltration rating, and environment.
2. The product is not certifi ed under the High Pressure
Gas Safety law, so for nitrogen, its maximum
operating pressure will be 0.99 MPa (gauge pressure).
3. The product is provided for use in manufacturing indus-
tries. Contact us beforehand if the product will be used
in an application such as a caisson shield, breathing,
food (other than air-blowing), and/or medical treatment
that affects the human body directly or indirectly.
4. The product removes and reduces bacteria contained in
the compressed air. Bacterial removal refers to the effect
of reducing bacteria. It does not mean that all bacteria are
eliminated. Not for eliminating the virus.
LRV (Log Reduction Value) is a mathematical representa-
tion that was obtained from the test (evaluation based on
JIS K 3835) using test bacteria (Brevundimonas diminuta).
5. The product is assembled and packaged in a clean room
environment but does not adhere to the sanitation control
procedures for the use in food and medical industries.
6. If the compressed air includes ozone, do not use it since
it may damage the product or cause malfunction.
Caution on Installation
Caution
1. If the pressure difference (pressure drop) between
the inlet and the outlet exceeds 0.1 MPa, it can
cause damage to the product.
2. Do not install the product in a place where it can be
affected by a pulsation (including surge pressure)
of over 0.1 MPa.
3. Use caution regarding the particles that may be
emitted from the outlet side of pneumatic equip-
ment.
The installation of pneumatic equipment on the outlet side can
deteriorate the cleanliness because a particle will be
generated from the equipment.
The mounting position of the pneumatic equipment needs to
be considered.
4. Set the air fl ow capacity with an initial pressure drop
of 0.03 MPa or less. If the initial pressure drop is set
to be high, its life will be shortened due to clogging.
5. Generally, the following pollutant particles are
contained in compressed air.
[Pollutant particle substances contained in the
compressed air]
· Moisture (drainage)
· Dusts and particles which are in the surrounding air
· Deteriorated oil which is discharged from the compressor
· Solid foreign matter such as rust and/or oil in the piping
1) The SFDA series is not compatible with compressed air
which contains fl uids such as water and/or oil.
2) Install a dryer (IDF, IDG, ID series), line fi lter (AFF-D
series), mist separator (AM series), micro mist separator
(AMD series), super mist separator (AME series), or odor
removal fi lter (AMF series), etc., for the source of the air for
the SFDA series.
6. Using with a fl ow-rate much higher than its
specifi cation could lead to exceeding the differential
pressure the product can resist.
Use the product within its specifi cations. Also, take care about
the replacement period of the product, taking into
consideration that the differential pressure of the fi lter will
increase over time.
Mounting
Warning
1. Operation manual
Install the products and operate them only after reading the
operation manual carefully and understanding its contents. Also,
keep the manual where it can be referred to as necessary.
2. Flushing
Flush the piping line before using the product for the fi rst time
and after it has been replaced. Also, if piping, etc., is to be
connected, fl ush (air blow) before using this product for the
fi rst time and after the element has been replaced in order to
reduce the effects of the dust generated from the connection,
etc. Flushing the line is also required to eliminate
contamination resulting from the installation of piping lines.
Therefore, be sure to fl ush the line before running the system.
Make sure all mounting parts are secure before use.
Caution
1. Connect the piping in accordance with the flow
direction marked on the case.
If connected in reverse, the element could break.
2. Mounting orientation does not affect the performance.
Be sure to read this before handling the products. Refer to the back cover for safety instructions.
