Selection
A safety device needs to be installed if output pressure is exceeding the set pressure, otherwise this
can cause the breakage of outlet device and equipment or malfunction.
AD17-A and AD27-A with auto drain may leak during exhaust of pressure. (This leakage is allowed
in their constructions and not failure.) Be sure to connect piping for drain.
Mineral grease used on internal surfaces and packing may leak to the outlet. Please contact SMC if
this is a problem.
Operating pressure: 0.1MPa or more at min. for AD17-A and AD27-A, 0.15MPa or more at min. for
AD37-A and AD47-A.
Consult SMC if using this product for purposes other than its primary use of lubricating air line
equipment.
Long absence of operation or operation with outlet circuit sealed or balance circuit may cause
pressure fluctuation in outlet set pressure. Please consult SMC if this is a problem.
Set pressure of outlet pressure shall be 85% or less of inlet pressure. Pressure over 85% makes
operation susceptible to flow and inlet pressure which lead to cause unstable operation.
N.O type auto drain should be used under the following requirements to avoid operating failure.
N.C. type auto drain should be used under the following requirements to avoid operating failure.
4
If multiple auto drains are used, confirm used compressor has capacity over the result of multiplying
the above capacity and the number of used auto drains.
{For example, in case of two auto drain, the compressor need the capacity over 1.5kW [200L/ min
(ANR)].}
Maximum set pressure range in the spec. has margin. Pressure set may be higher than the
maximum value.
If regulator is used with circuit which requires high exhaust sensitivity or set precision, please
consult SMC.
The use at high frequency such as the use in press machine may damage internal components and
cause operating failure of the equipment installed to secondary side. Contact SMC for such a use.
Small air consumption may prevent the oil from dropping. Confirm air flow necessary to produce the
drops required for the correct amount of oil.
Do not supply the air from secondary side (reverse air flow). Otherwise, internal components may be
damaged.
If piping is branched at inlet side, the oil may flow back. Avoid the reverse flow by installing a check
valve (AKM series) to inlet side.
It is possible to exhaust the residual pressure to the inlet when releasing the inlet pressure, but the
exhaust can fail at a set pressure of 0.15MPa or less.
When the backflow function is necessary at 0.15MPa or less, a regulator with backflow function is
recommended.

Installation
Adjustment
Adjust the pressure adjusting handle ensuring correct inlet pressure and outlet pressure.
Excessive rotation may cause damage to internal parts.
Adjustment of the oil adjustment valve should be carried out manually. The use of tools, etc. can
result in damage to the unit. (AL20-A to AL40-A)
Install the bowl vertically with bowl facing down. If it is inclined, dripping may not be confirmed.
Turning the oil adjustment 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. Please 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. (AL20-A to AL40-A)
Connect the product ensuring the direction of " " (IN) and " " (OUT) for air direction or an
arrow. Wrong connection may cause malfunction.
Install with enough space around each assembly component to perform regular maintenance and
operation. The required space is shown on 「11. Dimensions」 (P20 to 24).
Do not drop or apply impact during transportation or installation. It will cause damage to the
product or operation failure.
Do not install in areas of high humidity or high temperature. The product cannot be used in the
horizontal or upward directions outside of the specifications.
Install vertically so that outlet of drain would turned downward. Use with the outlet of drain turned
horizontal or upward causes malfunction.
When using a hexagon socket head cap screw to wall mount an air combination, we recommend
using a ballpoint screwdriver.
On AL10-A, some dripping may occur even when needle is fully opened.
djust pressure incrementally. Pressure may become lower than set pressure if adjusted by
decreasing the value. Rotate the handle clockwise to raise the set pressure. Counterclockwise to
reduce the pressure. Moreover, please lock the handle after setting pressure.
Outlet pressure may rise if eliminate the inlet pressure after pressure setting and supply pressure
again. The pressure becomes close to the set pressure after air is consumed in outlet.
Be sure to unlock the handle before adjusting the pressure and lock it after setting the pressure.
Failure to follow this procedure can damage the handle and the outlet pressure may fluctuate.

For the regulator with the pressure gauge, do not apply pressure exceeding the maximum scale
of the pressure gauge in order to protect the gauge.
・Push the pressure regulator handle to lock. When the handle is not easily locked, turn it
left and right a little and then push it. (When the handle is locked, the "orange mark", i.e.,
the gap will disappear.)

Outlet pressure may change if filter regulator is used for long periods. Please confirm set
pressure regularly.
When pressure difference between the inlet side and the outlet side is large, chattering
may occur. In that case, please reduce and use pressure difference between the inlet side
and the outlet side. Please consult SMC it chattering continues.
Blow out or clean piping before piping to eliminate swarf, cutting oil, solid foreign material.
Contamination of piping may cause damage or malfunction.
When installing piping, avoid chips and sealing materials from piping screws entering the
inside of equipment. Or malfunction may occur. When use sealing tapes, leave 1.5～2
threads of the end of thread exposed.
Hold the female screw side and screw in piping with recommended tightening torque.
Insufficient tightening torque lead to cause loose piping or sealing failure. Excessive
torque may lead to cause screw breakage. Tightening without holding female screw side
applies excessive force to the piping bracket which lead to cause breakage.
Use clean air. Compressed air containing chemicals, organic solvent, synthetic oil or
corrosive gas may lead to cause breakage of parts or malfunction.
Air containing too much moisture may cause malfunction. Install the air drier or the
aftercooler before the air combination.

Piping
Air Source
Do not apply any torsional moment, or bending moment except the weight of the filter
regulator itself. External piping needs to be supported separately. Hard piping like steel
tube is susceptible to excessive moment load or vibration. Insert the flexible tube to cancel
the influence.
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
should be performed with drain guide held by spanner to prevent breakage of bowl.
The piping for drain from auto drain should be connected under the following requirements
to avoid operating failure.
Avoid rising piping and piping branches on secondary side. Otherwise, lubricating failure
may be caused.

Open and close drain cock manually. Open and close too much may damage the drain cock.
Use class 1 turbine oil (without additives) ISO VG32. Using other lubricant can cause damage
to devices and result in malfunction.
In AL10-A and AL20-A series, lubrication during pressurization is not possible.
Exhaust the inlet pressure and check that there is no pressure within the product. Supply oil
after removing the oil supply plug.
The AL30-A and AL40-A have a slight leak from the inside of the case to the oil supply orifice.
Loosen the oil supply plug one turn and wait a short time for pressure to release then remove
the oil supply plug. As there is a slight leak from inside the case to the oil supply orifice, set the
oil supply to “Max Level” slowly, while ensuring an oil film is not created over the oil supply
orifice.
When removing the oil supply plug, pressure within the case will be released, so ensure that
protective goggles are equipped.
After oil is supplied, after ensuring that it is correctly positioned, the oil supply “O” ring can be
returned to its previous state by gently screwing it in.
(For tightening torque, see Operation Manual of Lubricator)
Maintenance
7
Maintenance and checks should be done by following the procedure in the operation manual.
Incorrect handling of the product may cause breakage or malfunction of the equipment or
device.
Perform periodical check to find cracks, flaw or other deterioration on the resin parts such as
bowl or sight dome. If any of these are seen, a malfunction has occured, replace with new
parts. Investigate and review the operating conditions if necessary.
Check for dirt in resin bowl periodically. If any dirt is seen, replace with new bowl. And if
removing off the dirt by washing instead of using a replacement, never use washing material
other than neutral detergent. Otherwise, the bowl is damaged.
Replace the element before 2 years passed since purchase or pressure drop from initial outlet
pressure reaches 0.1MPa. Or the element is broken.
When using the regulator and filter regulator with backflow function between a solenoid valve
and an actuator, check the pressure gauge periodically.
Sudden pressure fluctuations may shorten the durability of the pressure gauge. A digital
pressure gauge is recommended for such situation or as deemed necessary.
