Neptune manufactures two styles of By-Pass Feeders: a vertical design with dish bottom in, and a vertical design with dish bottom out. For added convenience, optional filters are available for system cleanup and monitoring. Each unit comes standard with a high-pressure cap rated to 300 psi (20.7 bar). These quick-opening caps are engineered for a tight seal with minimal force and require no tools for operation. Safety is built in-the design locks the cap securely under pressure, ensuring pressure must be bled off before removal.

For applications requiring both chemical addition and system filtration, the Neptune Filter Feeder combines these functions into a single, high-capacity unit. This dual-purpose solution makes it easy to feed solid or liquid chemicals into hot or cold closed water recirculation systems while maintaining system cleanliness.
