SMCs new AC series of modular type F.R.L. unit is available in 4 sizes and is interchangeable with the existing modular type AC line. 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 size 30 or more are now covered with a transparent bowl guard, completely protecting them from the environment, and making the inside visible from 360 degrees. The base color of the new AC series is urban white, maintaining a clean, modern look.
