Type A4
The Type A4 Filter Arm, manufactured by KSH Germany, features partially closed sections that force the fluid to pass more effectively through the filter medium, ensuring enhanced performance and a uniform backwash pattern. It is designed for use in KSH star systems Type SS6 and SS8 and is mounted to the centerpiece using a quick-release fastener for easy installation and removal.
