SMC redesigns its air preparation modular units, the AC series. The AC series design review is part of SMC’s ongoing investment in research and development to refine and improve the performance and functionality of its products, as well as developing new innovations to drive enhanced handling and space savings and deliver competitive advantages for customers. In this regard, the AC series brings a double layer structure bowl guard for better visibility and extended working life, while also bringing reduced time and space for maintenance. Much more space saving is achieved due to the compactness of the modular units and the integrated and selectable pressure gauges and switches. Moreover, the introduction of an in-bowl assembled element construction, together with a new bracket system that allows for initial tightening by hand, allows for easier control and quick in-hand maintenance and replacement of elements. Ideal for automotive, facility and machine manufacturing, these highly flexible F.R.L. units also feature a simple to use bowl lock button and interchangeable, modular mounting.
