Note 1) Set the inlet pressure to at least 0.05 MPa higher than the set pressure.
Drain guide is NPT1/8 (applicable to the AW20(K)-B) and NPT1/4 (applicable to the AW30(K)-B to AW60(K)-B). The auto drain port comes with Ø3/8" One-touch fitting (applicable to the
Note 2)
AW30(K)-B to AW60(K)-B).
Note 3) Drain guide is G1/8 (applicable to the AW20(K)-B) and G1/4 (applicable to the AW30(K)-B to AW60(K)-B).
Note 4) Option B, G, H, M are not assembled and supplied loose at the time of shipment.
Note 5) Assembly of a bracket and set nuts (applicable to the AW20(K)-B to AW40(K)-B). Including 2 mounting screws for the AW60(K)-B.
Note 6) When pressure is not applied, condensate which does not start the auto drain mechanism will be left in the bowl. Releasing th e residual condensate before ending operations for the day is
recommended.
Note 7) If the compressor is small (0.75 kW, discharge flow is less than 100 /min [ANR]), air leakage from the drain cock may occur during start of operations. N.C. type is recommended.
Note 8) 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.
When choosing with H (panel mount), the installation space for lead wires will not be secured. In this case, select "wiring top entry" for the electrical entry. (Select "wiring bottom entry" when the
Note 9)
semi-standard Y is chosen simultaneously.)
Note 10) Pressure can be set higher than the specification pressure in some cases, but use pressure within the specification range.
Note 11) Refer to Chemical data in the catalogue for chemical resistance of the bowl.
Note 12) A bowl guard is provided as standard equipment (polycarbonate).
Note 13) A bowl guard is provided as standard equipment (nylon).
Note 14) The combination of float type auto drain: C and D is not available.
Note 15) Without a valve function
Note 16) The combination of metal bowl: 2 and 8 is not available.
Note 17) For pipe thread type: NPT. This product is for overseas use only according to the new Measurement Law. (The SI unit type is p rovided 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 18) 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 19) : For pipe thread type: NPT only
Note 20) : Select with options: E1, E2, E3, E4.

Option/Semi-standard: Select one each for a to i
Option/Semi-standard symbol:
