Zinc Anode 4400/8400
Parts Desk Insights
This is the correct zinc replacement anode (SKU 353-840465) for Kasco 4400 and 8400 series aerators and circulators. Zinc anodes are the standard choice for salt and brackish water installations — if this unit operates in fresh water, a magnesium anode should be considered instead. Replace anodes annually or when 50% depleted to maintain effective corrosion protection on the motor housing. For the smaller 2400/3400 series, see the Kasco 243465 2400/3400 Zinc Anode.
