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.

This product is for overseas use only 
according to the new Measurement
