Note 1) Drain guide is NPT 1/8 (applicable to
the AW20-A) and NPT 1/4 (applicable
to the AW30-A to AW40-A). The auto
drain port comes with ø3/8" One-touch
fitting (applicable to the AW30-A to
AW40-A).
Note 2) Drain guide is G 1/8 (applicable to the
AW20-A) and G 1/4 (applicable to the
AW30-A to AW40-A).
Note 3) Option B, G, H, M are not assembled
and supplied loose at the time of
shipment.
Note 4) Assembly of a bracket and set nuts.
Note 5) 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 6) 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 7) When the pressure gauge is attached,
a 1.0 MPa pressure gauge will be fitted
for standard (0.7 MPa) type. 0.4 MPa
pressure gauge for 0.2 MPa type.
Note 8) Pressure can be set higher than the
specification pressure in some cases,
but use pressure within the specification
range.
Note 9) Refer to Chemical data on page 62 for
chemical resistance of the bowl.
Note 10) Standard material (polycarbonate)
Note 11) Without a valve function
Note 12) For thread type: NPT.
This product is for overseas use only
according to the new Measurement
Law. (The SI unit type is provided for
use in Japan.)
