The VKS-1 filtration vessel is all carbon steel construction and designed to the latest edition of the ASME pressure vessel code.  The VKS-1 is designed for in-line flow applications where a heavy-duty design, rugged construction, and long term durability are required. Operating conditions such as repeated shock and vibration do not affect the filtration element or its secure seating. Contact Kaydon with your application information to determine if the VKS-1 is the filtration solution for your application.
