Note 1) Drain guide is NPT1/8 (applicable to the AC20B-B) and
NPT1/4 (applicable to the AC25B-B to AC60B-B).
The auto drain port comes with φ3/8" One-touch fitting
(applicable to the AC25B-B to AC60B-B).
Note 2) Drain guide is G1/8 (applicable to the AC20B-B) and
G1/4 (applicable to the AC25B-B to AC60B-B).
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 flow 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 fitted for standard (0.85 MPa) type.
0.4 MPa pressure gauge for 0.2 MPa type.
Note 7) The bracket position varies depending on the T-spacer or
pressure switch mounting.
Note 8) Make sure that the outlet pressure is released to atmospheric
pressure using a pressure gauge.
Note 9) Pressure can be set higher than the specification pressure
in some cases, but use pressure within the specification range.
Note 10) Refer to Chemical data on page 3 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) For pipe thread type: NPT.
This product is for overseas use only according to the new
Measurement Law. (The SI unit typeis provided for use in Japan.)
Cannot be used with M: Round pressure gauge (with color zone).
Available by request for special.
The digital pressure switch will be equipped with the unit
conversion function, setting to psi initially.
Note 17) For options: E1, E2, E3, E4. This product is for overseas use only
according to the new Measurement Law. (The SI unit is provided
for use in Japan.)
Note 18) ○: For pipe thread type: NPT only
Note 19) △: Select with options: E1, E2, E3, E4.
