1. Operation Precautions
Selection/Caution on Design
Do not select a model exceeding specification ranges and carefully consider the
purpose of use, required specifications, and operating conditions, such as fluid,
pressure, flow rate, nominal filtration rating, and environment. Incorrect handling can
result in unexpected accidents.
Refer to "Air Preparation Equipment/Precautions" which can be found under "Handling Precautions for SMC
Products" in the catalog or on SMC website.

1. The product is not certified under the High Pressure Gas Safety law, so for nitrogen and Carbon
dioxide gas(gas), its maximum operating pressure will be 0.99 MPa (gauge pressure).
2. The product is provided for use in manufacturing industries. 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.
3. 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 representation that was obtained from the test
(evaluation based on JIS K 3835) using test bacteria (Brevundimonas diminuta).
4. 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.
5. If the compressed air includes ozone, do not use it since it may damage the product or cause
malfunction.
Caution on Installation
Warning
1. Initial pressure drop
Set the air flow 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.
2. Pressure fluctuation of the circuit
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. Generally, the following pollutant particles are contained in compressed air.
[Example: 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 fluids such as water and/or
oil.
2) Install a dryer, line filter, mist separator, micro mist separator, super mist separator, or
odorremoval filter, etc., for the source of the air for the SFDA series.
3) Use a grade that meets ISO8573-1: 2010 [1: 4: 1] for the compressed air purity classes on the
inlet side of the SFDA series.
