OVERVIEW
SMC'S new AC-B series of modular type F.R.L. unit is available in six basic sizes and is interchangeable with the existing modular AC line. The AC-B series has a maximum set pressure of 125 psi and offers embedded gauge and pressure switch options not found in the AC-A. The element and bowl on the AF series is now one-piece, making element replacement easier. Required maintenance space has been reduced by as much as 46% on the AFseries, depending on the body size. Bowls on size 30 and up are now covered with a transparent bowl guard, completely protecting them from the enviromnent, and making the interior contents visible from 360 degrees. The base color of the new AC-B is uban white, maintaining a clean, modern look.
- Filter, regulator, and lubricator unit
- Clean looking, modular design
- One-piece element and bowl for easy replacement (AW)
- Transparent bowl guard for 360 degree visibility
- Embedded gauge and pressure switch options available
- Rc(PT), G(PF) or NPT threads

*1 Drain guide is NPT1/8 (applicable to the AC20A-B) and NPT1/4 (applicable to the AC30A-B to AC60A-B).
The auto drain port comes with ø3/8" One-touch fitting (applicable to the AC30A-B to AC60A-B).
*2 Drain guide is G1/8 (applicable to the AC20A-B) and G1/4 (applicable to the AC30A-B to AC60A-B).
*3 Options G, M are not assembled and supplied loose at the time of shipment.
*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.
*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 of operations. N.C. type is recommended.
*6 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.
*7 Not available with piping port size: 06
*8 The bracket position varies depending on the pressure switch mounting.
*9 Pressure can be set higher than the specification pressure in some cases, but use pressure within the specification range.
*10 Refer to chemical data on page 46 for chemical resistance of the bowl.
*11 A bowl guard is provided as standard equipment (polycarbonate).
*12 A bowl guard is provided as standard equipment (nylon).
*13 The combination of float type auto drain: C and D is not available.
*14 Without a valve function
*15 The combination of metal bowl: 2 and 8 is not available.
*16 When choosing with W: Filter drain port, the drain cock of a lubricator will be with barb fittings.
*17 For pipe thread type: NPT.
This product is for overseas use only according to the new Measurement Act. (The SI unit type is provided for use in Japan.)
Cannot be used with M: Round type pressure gauge (with color zone). Available by request for special.
The digital pressure switch will be equipped with the unit selection function, setting to psi initially.
*18 For options: E1, E2, E3, E4. This product is for overseas use only according to the new Measurement Act. (The SI unit is provided for use in Japan.)
