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) In the HF2-BF* series, compressed air containing liquid such as water and oil cannot be used.
2) At the air supply unit used for the HF2-BF* series, we recommend that you install a dryer (IDF,
IDG, ID), a line filter (AFF-D series), a mist separator (AM series), a micro mist separator
(AMD series), a super mist separator (AME series), an odor removal filter (AMF series), and
an active carbon filter (AMK 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 HF2-BFD series.
Maintenance
Warning
(1) Release the pressure in the product to the atmosphere when replacing parts or removing piping.
(2) Maintenance and checks should be done by following the procedure in the operation manual.
Incorrect handling of the product may cause breakage or operation failure of the equipment or
device.
(3) Do not touch the product when operating at high temperature (40 to 60
o
C). The operators may get
burnt. Be sure to confirm that the temperature of the container or operating part is reduced to 40
degrees or less to prevent burns.
(4) Perform periodical check to find cracks, flaws or other deterioration on resin bowl. If any of them is
seen. Investigate and/or review the operating conditions if necessary.
(5) Check for dirt in resin bowl periodically. If any dirt is seen, replace with new bowl. If removing dirt
by washing the resin bowl, never use washing material other than neutral detergent. Otherwise, the
bowl is damaged.
(6) Replace the element after referring to the replacement period below. The element could break.
a) HF2-BFA, HF2-BFB, HF2-BFD
Before 1 years passed from start of use or pressure drop (difference between the inlet
pressure and outlet pressure) reaches 0.1MPa.
b) HF2-BFC
Before 1 year or 2000 operating hours passed from start of use as it may deteriorate the
performance.
The replacement period of the element varies depending on the operating conditions. Even
before the aforementioned replacement period is reached, if there is an oil smell on the outlet
side, please replace it.
