Precautions for Design
Warning
(1) Consult SMC if no leakage is allowed due to the environment, or if the operating fluid is not air.
(2) Polycarbonate resin is used for the external parts including the bowl. Organic solvents including
thinner, acetone, alcohol and ethylene chloride; chemicals including sulphuric acid, nitric acid and
hydrochloric acid; cutting oil, synthetic oils, ester-based compressor oil, alkali, kerosene, gasoline,
lock material of screw are harmful. Do not use the product where these are present.
Chemical resistance of polycarbonate and nylon bowl
Note1) When the above factors are present or there is some doubt, use a metal bowl for safety.
Note2) The display window of the element service indicator of semi standard products is made of
nylon.
(3) Avoid the application where charge and discharge of pressure to/from a standard bowl is switched
frequently. This may damage the bowl.Ametal bowl is recommended in these cases.
(4) Shield from ultra violet light and radiation with protective cover.

Caution
(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.
Selection
Warning
(1) Grease used on the internal sliding parts and seals may flow to the outlet side. If this is not
acceptable, please consult SMC.
(2) 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.
(3) N.C. type auto drain should be operated under the following conditions to avoid malfunction.
Operating pressure forAD27: 0.1 MPa or more, for AD37 and AD47: 0.15 MPa or more.
Installation
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 and indicated
arrow. Incorrect connections may cause malfunction.
(4) Install with adequate space for maintenance beneath the product. Refer to the section [12.
Dimensions] (P30) for necessary space.
(5) Install vertically so that outlet of drain is downward. It cannot be used in horizontal or upward
direction as it may cause operation failure.
Piping
Warning
(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 bracket directly, leading to breakage.

(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-

(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. Non-flexible piping like steel tube is
susceptible to excessive moment load or vibration. Insert flexible tubes to prevent this.
(6) 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.
(7) The piping for drain from auto drain should be connected under the following requirements to
avoid operating failure.
Tubing forAD27-D: I.D. ø2.5 (ø3/32") or larger, Length 5 m (200 inch) or shorter
Tubing forAD37, 47(N)-D: I.D. ø4 (ø3/16") or larger, Length 5 m (200 inch) or shorter
Tubing forAD38, 48(N)-D: I.D. ø6.5 (ø1/4") or larger, Length 5 m (200 inch) or shorter
Air Source
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) Air containing too much moisture may cause malfunction. Install an air drier or aftercooler before
the air filter.
Handling Precautions
Warning
(1) Element service indicator (semi-standard: L) is used to check the differential pressure between IN
and OUT ports. When the differential pressure exceeds 0.025 Mpa, the element service indicator
may start even when the element is in initial state.
(2) When adjusting the flow rate of the product with an element service indicator, adjust the flow rate
from minimum to maximum. When the flow rate exceeds the maximum value, readjust the flow rate
from zero.
(3) As the element goes through its service life and begins to clog, the red part of the element service
indicator appears. Ensure that the element is replaced before the red indication reaches the upper
level.
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 this operation manual.
Incorrect handling of the product may cause breakage or operation failure of the equipment or
device.
(3) Perform periodical check to find cracks, flaws or other deterioration on resin bowl.
If any of these appear, replace with a new or metal bowl. Otherwise, breakage may occur.
Investigate and/or review the operating conditions if necessary.
(4) 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.
(5) Open and close the drain cock manually. The use of tools can result in damage to the product.
(6) 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.
(7) Discharge drain in the bowl before it reaches the element assembly. Refer to the section [8.
Operation andAdjustment] (P20-21) for discharging of drain.
-6-

Caution
(1) 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.
(2) For the N.C. type auto drain, when there is no pressure, drain which does not operate the auto
drain mechanism will remain in the bowl. It is recommended to release the residual drain manually
at the end of the working day.

2. Application
This product aims at eliminating excess saturated water and solid foreign matter in the air line.
