| Extends the life of the membranes by rinsing them with fresh water by merely a touch of a button. The Fresh Water Flush automatically removes all salt water from internal parts of the system and flushes the membranes with clean fresh water every 7 days. This prevents salt water corrosion of the internal parts and reduces biological fouling of the RO membrane. | The Remote Control Unit (RCU) is able to monitor the system's performance and alarm status from the bridge or other remote locations. This RCU includes complete installation instructions and 50 feet of cable. | The Plankton Filter Assembly (PFA) traps suspended solids larger than 100 micron, thus providing additional protection for your Seafari system's pre-filters, which ultimately prolongs the pre-filter element life. | Charcoal Filter Assembly (CFA) removes chlorine, taste, odors, and chemical impurities from the product water. This process of purification works without chemicals and leaves no residual in the water supply. |
