CAUTION
WARNING
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.
N.O. type auto drain should be used under the following requirements to avoid operating
failure.
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.
Protect from ultra violet ray and radiation heat by shield.
Output of compressor: 0.75kW or more.
Discharged flow rate: 100L/min (ANR) or more.
If multiple auto drains are used, confirm used compressor has capacity over the result of
Maximum set pressure range in the spec. has margin. Pressure set may be higher than the
maximum value.
If filter regulator is used with circuit which requires high exhaust sensitivity or set precision,
please consult SMC.
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.
The use outside specifications is prohibited.
Air consumption from release port is 0.1L/min(ANR) or less.
Selection
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.
Synthetic oil and mineral grease used on internal surfaces and packing may leak to the
outlet. P
lease contact SMC if this is a problem.
CAUTION
WARNING
Adjust the pressure adjusting handle ensuring correct inlet pressure and outlet pressure.
Excessive rotation may cause damage to internal parts.
Operate the pressure adjusting handle manually. Tools may break the handle.
Operating pressure: 0.1MPa or more at min..
Operating pressure: 0.1MPa or more at min. for AD27-A, 0.15MPa or more at min. for
AD37-A and AD47-A.
N.C. type auto drain should be used under the following requirements to avoid operating
failure.
Do not install in areas of high humid or high temperature. Or pressure gauge may
malfunction.
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.
Connect the filter regulator ensuring the direction of " " (IN) and " " (OUT) for air direction
or an arrow. Wrong connection may cause malfunction.
Install vertically so that outlet of drain would turned downward. Use with the outlet of drain
turned horizontal or upward causes malfunction.
Install with enough space around filter regulator to perform regular maintenance and
operation. The required space is shown on 11. Dimensions (P36).
Do not drop nor apply impact during transportation or installation. This can cause damage to
the product.
{ For example, in case of two auto drain, the compressor need the capacity over 1.5kW
[200L/min (ANR)]. }
