Compliance Requirements

1. The use of SMC products with production equipment for the manufacture of weapons of mass destruction(WMD) or any other weapon is strictly prohibited.
2. The exports of SMC products or technology from one country to another are governed by the relevant security laws and regulations of the countries involved in the transaction. Prior to the shipment of an SMC product to another country, assure that all local rules governing that export are known and followed.

Caution
SMC products are not intended for use as instruments for legal metrology.
Measurement instruments that SMC manufactures or sells have not been qualified by type approval tests relevant to the metrology (measurement) laws of each country.
Therefore, SMC products cannot be used for business or certification ordained by the metrology (measurement) laws of each country.

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 the SMC website. http://www.smcworld.com

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 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)
   – Dust 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, odor removal filter, etc., for the source of the air for the SFDA series.
3. Use a grade that meets ISO8573-1: 2010 [1: 4: 4] for the compressed air purity classes on the inlet side of the SFDA series.

Operating Environment
Warning

1. Do not operate under the conditions listed below due to a risk of malfunction.
   – In locations containing corrosive gases, organic solvents, and chemical solutions, or in locations in which these elements are likely to adhere to the equipment
   – In locations in which seawater, water, or water steam could come in contact with the equipment
   – In locations that are exposed to direct sunlight (Shield the equipment from sunlight to prevent its resin material from ultraviolet ray degradation or overheating.)
   – In locations that have a heat source and poor ventilation (Shield the equipment from heat sources to protect it from softening degradation due to radiated heat.)
   – In locations that are exposed to shocks and vibrations
   – In locations with high humidity or large amounts of dust

2. When the product is used for blowing, use caution to prevent the work from being damaged by entrained air from the surrounding area.
   If compressed air is used for air blow, compressed air blowing out from the blow nozzle may entrain foreign matter (solid particles and liquid particles) floating in the ambient air, blowing it against the workpieces and causing adhesion. Therefore, sufficient precautions must be taken about the ambient environment.

Mounting

Warning

1. Flushing
   – Flush and clean the piping before installing the product. Dust and foreign matter left in the piping can cause operating failure and malfunction.
   – When connecting pipework, flush before initial use and element replacement to reduce particle generation. After that, start main operation.

2. Unpacking the sealed package
   Since the filter is sealed in an antistatic double bag, the inner package should be unpacked in a clean atmosphere (such as a clean room).

3. Piping ports
   – When connecting pipework, apply a wrench across the flats of the IN or OUT side to prevent the main body from rotating.
   – Connect the piping in accordance with the flow direction marked on the case.
   If connected in reverse, the element could break.

4. Installation
   Secure the product with the brackets included in the packaging.

Maintenance

Warning
Perform maintenance and inspection according to the procedures indicated in the operation manual. If handled improperly, malfunction or damage of machinery and equipment may occur.

1. When removing the product, exhaust the air and ensure the air is released into the atmosphere before removing it.
2. When the element comes to the end of its life, immediately replace it with a new filter or replacement element.
   – Life of element –
   The life of the element ends when either of the following two conditions occurs.

1. After 1 year of usage has elapsed.
2. When the pressure drop reaches 0.1 MPa even though the operating period has been less
   than 1 year
