Farwest “W” series auto-potential controlled
cathodic protection rectifiers,
manufactured by Universal Rectifiers, Inc., are
specifically designed for the Water Tank Industry.
Proven, dependable solid state control boards maintain
strict “Standard On” or “I.R.Free” potentials.
Easy-to-read, bright LED digital meters provide accurate
readings of volts, amps and potentials. These compact,
light-weight rectifiers can easily be mounted on tank
walls or posts by one person.
