SMC S series AW-A is a combination filter/regulator, minimizing space and piping by integrating two units into one. The pressure drop across the regulator section has been reduced creating a more efficient unit with a maximum set pressure of 100 psi. The element and bowl on the AW-A series is now one-piece, making element replacement easier. Bowls on the size 30 and 40 are covered with a transparent bowl guard, completely protecting them from the environment and making the interior contents visible from 360 degrees. This series is part of the family of modular air preparation units and can be combined with other similar sized products. The new AW-A is available in four body sizes with piping from M5 to 3/4 in Rc, NPT, and G thread types.
