OVERVIEW
SMC'S new AC-A series of modular type F.R.L. unit is available in five sizes and is interchangeable with the existing modular AC line. The pressure drop across the regulator has been reduced creating a more efficient unit with a maximum set pressure of 100 psi. The element and bowl on the AW and AF series is now one-piece, making element replacement easier. Required maintenance space has been reduced by as much as 46% on the AF series, depending on the body size. Bowls on the size 30 and 40 are now covered with a transparent bowl guard, completely protecting them from the environment, and making the interior contents visible from 360 degrees. The base color of the new AC-A series is urban white, maintaining a clean, modern look.
- Air filter and regulator unit
- Clean looking, urban white, modular design
- Element and bowl are in one-piece for easy replacement (AF)
- Energy saving regulator (AR)
- Transparent bowl guard provides 360 degree visibility

Note 1) Drain guide is NPT1/8 (applicable to the AC20B-A) and NPT1/4 (applicable to the AC25B-A to AC40B-A). The auto drain port comes with ø3/8" One-touch fitting (applicable to the AC25B-A to AC40B-A).
Note 2) Drain guide is G1/8 (applicable to the AC 20 B- A) and G 1 / 4 ( applicable to the AC25B-A to AC40B-A).
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 ofoperations. N.C. type is recommended.
Note 6) When the pressure gauge is attached, a 1.0 MPa pressure gauge will be fitted for standard (0.7 MPa) type. 0.4 MPa pressure gauge for 0.2 MPa type (1.0 MPa pressure gauge only for the AC10B-A).
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. For V1 specification, use the regulator with a set pressure of 0.15 MPa or more to ensure the pressure release.
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 689 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: M5, NPT. This product is for overseas use only according to the new Measurement Law. (The SI unit type is provided for use in Japan.) MPa and psi are shown together on the pressure unit. Cannot be used with M: Round pressure gauge (with color zone). Available by request for special.
Note 17) v: For pipe thread type: M5, NPT only
