The Pulsar® 73280 Pulsar Precision High Capacity CalHypo Erosion System Feeder Component is a component of the high capacity erosion (HCE) feeder system that is both compact and lightweight with a modular design. This item is the feeder unit only, and must be connected to and used with other system components to function as intended. The completed feeder system uses Pulsar® calcium hypochlorite briquettes (sold separately) that work in conjunction to produce a fresh concentrated liquid chlorine solution for clean and sanitized water. The flexible design allows for easy integration into commercial pools ranging from small to large.
