○Air filter, lubricator, filter regulator and mist separator
(1) Avoid the application where charge and discharge of pressure to/from a standard bowl is
switched frequently. This may damage the bowl. A metal bowl is recommended in these cases.
○ Regulator and filter regulator
(1) A safety device needs to be installed if output pressure is exceeding the set pressure, otherwise
this can cause breakage of outlet device and equipment or lead to malfunction.
Caution
○Air filter, filter regulator and mist separator
(1) AD27-D with auto drain may have leakage of accumulated drain during pressure exhaust (this
leakage is allowed in their constructions and not considered failure). Be sure to connect piping for
drain.
○ Regulator and filter regulator
(1) Allowed air consumption from the exhaust port is 0.1 L/min(ANR) or less.
Selection
Warning
○ Air combination
(1) Grease used on the internal sliding parts and seals may flow to the outlet side. If this is not
acceptable, please consult SMC.
○ Air filter, filter regulator and mist separator
(1) N.O. type auto drain should be operated under the following conditions to avoid malfunction.
Operating compressor: 0.75 kW or more, Discharged flow rate: 100 L/min (ANR) or more
When using 2 or more auto drains, multiply the value above by the number of auto drains to find
the capacity of the compressors you will need. For example, when using 2 auto drains, 1.5 kW
(200 L/min (ANR)) of the compressor capacity is required. The operating pressure should be
0.1 MPa or more.
(2) N.C. type auto drain should be operated under the following conditions to avoid malfunction.
Operating pressure for AD27: 0.1 MPa or more, for AD37 and AD47: 0.15 MPa or more.
○ Regulator and filter regulator
(1) Residual pressure of product without backflow function is released unstably even though the inlet
pressure is released (residual pressure might be left in the product). Please select product with
backflow function to release the residual pressure completely.
(2) Long absence of operation or operation with sealed circuit or balancing circuit on the outlet side
may cause set pressure fluctuation. Please consult SMC if this is not acceptable.
(3) Set range of outlet pressure shall be 85% or less of the inlet pressure. Operating at a setting
exceeding 85% causes the outlet pressure to be easily affected by fluctuations in flow rate and
inlet pressure, leading to instability.
(4) Since the safety margin is calculated to the maximum value of the set pressure range shown in the
specification table, the pressure setting may be over the maximum value. However, use the
product within the specified range.
(5) If the product is used with circuit which requires high exhaust sensitivity or set precision, please
consult SMC.
○ Lubricator
(1) Please consult SMC when the lubricator is used other than for lubricating pneumatic equipment.
(2) Please consult SMC when the lubricator is used at high frequency, such as press machine, as the
internal components may break or operation failure may occur on the outlet side equipment.
(3) If the air consumption is small, oil may not drip. Select a proper size of product according to the
minimum dripping flow rate.
(4) Do not flow from the outlet side (backflow) as it may cause breakage of the internal components.
(5) When the piping is branched on the inlet side, install a check valve to prevent the lubricant from
back flowing.

Adjustment
Warning
○ Regulator and filter regulator
(1) Adjust the set pressure ensuring correct inlet and outlet pressures. Turning the knob
excessively can cause damage to the internal parts.
(2) Do not use tools on the pressure regulator knob as this may cause damage. It must be
operated manually.
○Lubricator
(1) Adjustment of the oil regulating valve should be carried out manually. The use of tools etc. can
result in damage to the unit.
(2) Turning the oil regulating valve counterclockwise increases the dripping amount, and turning it
clockwise reduces the dripping amount. From the fully closed position, three rotations will
bring it to the fully open position. Do not rotate it any further than this. Note that the numbered
scale markings are guidelines for adjusting the position, and not indicators of the dripping
amount.
Caution
○ Regulator and filter regulator
(1) Check the inlet pressure before setting up.
(2) Be sure to unlock the knob before adjusting the pressure and lock it after setting the pressure.
Failure to follow this procedure can cause damage to the knob and the outlet pressure may
fluctuate.
-Pull the pressure regulator knob to unlock (You can visually verify this with the “orange mark”
that appears in the gap).
-Push the pressure regulator knob to lock. When the knob is not easily locked, turn it left and
right a little and then push it (when the knob is locked, the “orange mark”, i.e., the gap will
disappear).
(3) For the product with a pressure gauge, do not apply pressure exceeding the maximum scale
of the pressure gauge in order to protect the gauge.
(4) Adjust the pressure whilst the pressure is increasing. Pressure may become lower than the
set pressure if adjusted by decreasing the value. Rotate the knob clockwise to increase the
set pressure. Counterclockwise to decrease the pressure. Moreover, please lock the knob
after setting pressure.
(5) Outlet pressure may rise when the inlet pressure is discharged and resupplied after pressure
setting. In this case, consume air at the outlet which will bring the pressure closer to the set
pressure.
(6) Outlet pressure may change if the product is used for a long period of time. Please confirm the
set pressure regularly.

Piping
Warning
○ Air combination
(1) Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to
remove chips, cutting oil and solid foreign material from inside the pipe. 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 leads to cause of loosening or sealing failure, and
excessive tightening torque leads to cause of breakage of screws. Tightening without holding
female thread applies an excessive force to the piping bracket directly, leading to breakage.
Recommended tightening torque Unit: N m
Thread size 1/8 1/4 3/8 1/2 3/4 1
Torque 3 to 5 8 to 12 15 to 20 20 to 25 28 to 30 36 to 38
(4) Before using an SMC fitting and S coupler, please refer to "Tightening the threaded portion of
the connection thread" of the Fittings & Tubing Precautions.
(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 breakage. If moment applied to the
equipment is unavoidable during operation, the moment should be lower than the maximum
moment shown below. Non-flexible piping like steel tube is susceptible to excessive moment
load or vibration. Insert flexible tubes to prevent this.

Max. moment (M) [N m] 14.5 16 19.5 35 45 45
Max. moment (M) = Length (L) x Load (F)
○ Air filter, filter regulator and mist separator
(1) Drain guide is not equipped with valve function. Be sure to connect piping for drain. No piping
for drain allows the drain and compressed air to exhaust freely. Also, the piping installation
should be performed with drain guide held by spanner to prevent breakage of bowl.
(2) The piping for drain from auto drain should be connected under the following requirements to
avoid operating failure.
Tubing for AD27-D: I.D. ø2.5 (ø3/32") or larger, Length 5 m (200 inch) or shorter
Tubing for AD37, 47(N)-D: I.D. ø4 (ø3/16") or larger, Length 5 m (200 inch) or shorter
Tubing for AD38, 48(N)-D: I.D. ø6.5 (ø1/4") or larger, Length 5 m (200 inch) or shorter
Caution

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 μm 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.

Caution
○ Regulator and filter regulator
(1) If an emergency countermeasure is to be taken during setting failure or exhaust leakage, the
internal valve seating part should be checked. If failure such as foreign matter is found,
remove it before performing the emergency countermeasure.
○ Air filter, filter regulator and mist separator
(1) Rotate the knob counterclockwise (O←direction) to exhaust drain from the C2SF(-C)-D.
Press the push button to exhaust drain from the C3SF(-W)-D and C4SF(-W)-D.
(2) Check the element periodically and replace it with a new one if necessary. If it is found that
outlet pressure drops lower than the normal condition or the flow is restricted during operation,
check the condition of the element.
(3) The emergency manual exhaust of AD27-D can be performed by rotating the knob
counterclockwise (O←direction).
The emergency manual exhaust of AD37, 38, 47 and 48-D can be performed by rotating the
drain cock counterclockwise (O←direction).
○ Lubricator
(1) Check the dripping amount once a day. Drip failure can cause damage to the components that
need lubrication.
(2) Use clean oil. Otherwise, it may cause dripping failure or clogging.
(3) The lubrication amount should be less than the upper limit of oil level of the bowl.
(4) Discharge drain periodically so that the drain is not accumulated beyond the upper limit of the
drain level of the bowl. If a large amount of drain enters lubricator, it may cause dripping
failure.
