This RFI kit is specifically designed to cure most sprinkler control systems triggered by Radio Frequency Interference problems. The kit contains a large (ID = 1") snap on filter for the AC power Line protection and snap on ferrite beads for 4 sprinkler control lines. (Multiple control lines can go through the same ferrite filter) The ferrites are selected to eliminate RFI from 1 to 300 MHz. The ferrites are easy to use, don’t require modification of the protected equipment and work in almost all cases.

If you need control line filters for more than 4 control line "bundles" order part # FSB31-1/2.
