Air Source
Warning
○
Air combination
(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)
Use an air filter with 5
μ
m or less filtration rating on the inlet side of the valve to avoid any
damage to the seat caused by dust when mounting a pressure relief 3 port valve.
(3)
Air containing too much moisture may cause malfunction. Install an air drier or aftercooler
before the air combination.
Maintenance
Warning
○
Air combination
(1)
Maintenance and checks should be done by following the procedure in this operation manual.
Incorrect handling of the product may cause breakage or operation failure of the equipment or
device.
○
Air filter, lubricator, filter regulator and mist separator
(1)
Perform periodical check to find cracks, flaws or other deterioration on resin bowl.
If any of these appear, replace with new parts. Otherwise, breakage may occur. Investigate
and/or review the operating conditions if necessary.
(2)
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.
(3)
Open and close the drain cock manually. The use of tools can result in damage to the product.
○
Air filter, filter regulator and mist separator
(1)
Replace the element every 2 years or when the pressure drop at the output pressure from
initial operation becomes 0.1 MPa, whichever comes first, to prevent damage to the element.
(2)
Discharge drain from the bowl before the drain level in the bowl reaches baffle. If drain enters
the outlet side, it can cause operation failure of the equipment.
○
Lubricator
(1)
Use class 1 turbine oil (with no additives) ISO VG32. Using other lubricant can cause damage
to devices and result in malfunction.
(2)
AL20-D cannot replenish lubricate while being pressurized. Before lubrication, exhaust the
inlet pressure and make sure that there is no pressure in the bowl.
(3)
AL30-D, AL40-D, AL50-D and AL60-D have a small amount of leakage from the bowl to oil
supply port. Slowly loosen the oil supply plug approximately 1 turn and wait until the pressure
in the bowl is released, and then, remove the oil supply plug. Be sure to wear safety goggles
when removing the oil supply plug as the pressure in the bowl is released. After removing the
oil supply plug, supply oil slowly up to the upper limit of oil level while ensuring that no oil film
is created over the oil supply port.
After supplying oil, confirm that the O-ring on the oil supply plug is mounted correctly and
mount the oil supply plug. It returns to the original condition by pushing the oil supply plug
lightly.
