(3) Avoid the application where charge and discharge of pressure to/from a standard bowl is switched frequently.

(4) Shield from ultra violet light and radiation with protective cover.

(5) For air blow applications, prevent airborne particles from the operating environment entering into the compressed air stream. Foreign matter may adhere to the workpiece during the air blow.

(6) If the air equipment is mounted on the outlet of the product, particles will be generated from the equipment and required cleanliness may not be obtained. Instead, install the air equipment at the inlet.

(7) Using a flow rate which exceeds the product specifications could result in a differential pressure which exceeds what the product can resist.

Use the product within its specifications. Also, be sure to replace the product when needed, taking into consideration that the differential pressure of the filter will increase over time.

Selection

Warning

(1) NFS-H1 grade grease is used where lubrication is required.

(2) 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.

(3) 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).

(4) 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.

(5) The antibacterial activity value of the HF2-BFA and HF2-BFB series is achieved through contact with the element surface. If the fiber surface is covered by drains, etc., it will not be as effective. The antibacterial activity value are based on the test method for determination of antibacterial activity and efficiency of textile products (JIS L 1902).

(6) HF2-BFC series adsorbs oil vapor contained in the compressed air and removes the odors derived from it, but does not remove all odors.

(7) HF2-BFD series 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).

(8) The product does not adhere to the sanitation control procedures for the use in food and medical industries.

Since the parts used in the HF2-BF

∗

series are manufactured on the same line as parts made of other materials, in rare cases these parts may have residuals from the manufacturing process.

(9) If the compressed air includes ozone, do not use it since it may damage the product or cause malfunction.

5

Mounting

Warning

(1) Do not drop or apply impact during transportation or installation; It will cause damage to the product and result in operation failure.

(2) Do not install in areas of high humidity or high temperature. Operation outside of the product specification range may cause damage to the product or operation failure, or shorten the product life.

(3) Connect the product ensuring the direction of "1"(IN) and "2"(OUT) for air direction or an arrow.

Incorrect connections may cause malfunction.

(4) Install with adequate space for maintenance beneath the product. Refer to 7. Dimensions (page

17) for necessary space.

(5) Install vertically so that outlet of drain is facing downward. It cannot be used in horizontal or upward direction.

Caution

(1) When the bowl is installed on HF2-BF

∗

series, install them so that the lock button lines up to the groove of the front (or the back) of the body to avoid drop or damage of the bowl.

Piping

Warning

(1) Before piping, perform flushing or cleaning of the piping, etc. to remove any cutting chips, cutting oil, solid foreign matter, etc. from the piping. Contamination of piping may cause damage or malfunction.

(2) When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealant do not get inside the pipe. When a sealant tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads.

(3) Connect piping/fittings using the recommended torque while holding the female thread side tightly.

Insufficient tightening torque can cause loose piping or sealing failure. Excess tightening torque may cause damage to threads. If the female side is not held while tightening, excessive force will be applied to the bracket directly, causing breakage.

Recommended tightening torque (Unit: Nm)

Thread 1/8 1/4 3/8 1/2

Torque 7 to 9 12 to 14 22 to 24 28 to 30

(4) When a one-touch fitting of SMC is used, refer to the operation manual for the one-touch fitting.

(5) Do not apply torsion or bending moment other than the weight of the product itself. External piping needs to be supported separately as it may cause damage. Non-flexible piping like steel tube is susceptible to excessive moment load or vibration. Insert flexible tubes to prevent this.

6

Air supply

Warning

(1) Use clean air. Do not use compressed air containing chemicals, organic solvent, synthetic oil or corrosive gas as it may be cause of breakage of components or operation failure.

(2) 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 HF2-BF

∗

series is not compatible with compressed air which contains fluids such as water and/or oil. Install a dryer, line filter, mist separator, micro mist separator, super mist separator, or odor removal filter, etc., for the source of the air for the HF2-BF

∗

series.

2) Use a grade that meets ISO8573-1: 2010 [1: 4: 4] for the compressed air purity classes on the inlet side of the HF2-BF

∗

series.
