Note 1) Drain guide is NPT1/8 (applicable to the AC20A-A) and 
NPT1/4 (applicable to the AC30A-A to AC40A-A). The 
auto drain port comes with ø3/8" One-touch fitting 
(applicable to the AC30A-A to AC40A-A).
Note 2) Drain guide is G1/8 (applicable to the AC20A-A) and 
G1/4 (applicable to the AC30A-A to AC40A-A).
Note 3) Option G, M are not assembled and supplied loose at 
the time of shipment.
Note 4) When pressure is not applied, condensate which does 
not start the auto drain mechanism will be left in the 
bowl. Releasing the residual condensate before ending 
operations for the day is recommended.
Note 5) If the compressor is small (0.75 kW, discharge fl ow is 
less than 100 L/min[ANR]), air leakage from the drain 
cock may occur during start of operations. N.C. type is 
recommended.
Note 6) When the pressure gauge is attached, a 1.0 MPa 
pressure gauge will be fi tted for standard (0.7 MPa) type. 
0.4 MPa pressure gauge for 0.2 MPa type (1.0 MPa 
pressure gauge only for the AC10A-A). 
Note 7) Not available with piping port size: 06
Note 8) The bracket position varies depending on the pressure 
switch mounting.
Note 9) Pressure can be set higher than the specification 
pressure in some cases, but use pressure within the 
specifi cation range.
Note 10) Refer to Chemical data on page 38 for chemical 
resistance of the bowl.
Note 11) A bowl guard is provided as standard equipment 
(polycarbonate).
Note 12) A bowl guard is provided as standard equipment 
(nylon).
Note 13) Float type auto drain: The combination of C and D is 
not possible.
Note 14) Without a valve function
Note 15) The combination of metal bowl: 2 and 8 is not available.
Note 16) When choosing with W: Filter regulator drain port, the 
drain cock of a lubricator will be with barb fi tting.
Note 17) For pipe thread type: M5, NPT. MPa and psi are shown 
together on the pressure unit. Cannot be used with M: 
Round pressure gauge (with colour zone). Available by 
request for special.
Note 18) 
: For pipe thread type: M5, NPT only
