Standard Specifications
Note 1) Pressure gauge connection threads are not available for F.R.L. unit with a square embedded type pressure gauge or with a digital pressure switch.
Note 2) 23 to 122°F (–5 to 50°C) for the products with the digital pressure switch
Filter Regulator
Series AW20-B to AW60-B
Filter Regulator with Backflow Function Series AW20K-B to AW60K-B
Note 1) Set the inlet pressure to at least 7.3 psi (0.05 MPa)
higher than the set pressure.
Note 2) 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 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 the residual condensate
before ending operations for the day is recommend-
ed.
Note 7) If the compressor is small (0.75 kW, discharge flow
is less than 3.5 scfm (100 L/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 145 psi
(1.0 MPa) pressure gauge will be fitted for standard
(123 psi [0.85 MPa]) type. 58 psi (0.4 MPa)
pressure gauge for 2.9 psi (0.2 MPa) type.
Note 9) 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 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 on page 90 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 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 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.
