The Regal Gas Chlorinator is a direct cylinder-mounted, all-vacuum system in which chlorine gas is drawn through the unit with vacuum created by the flow of water through the ejector. If the vacuum line breaks or is damaged, the gas shuts of automatically. The system also features a reusable filter that removes impurities, while permitting flow rates up to 500 pounds per day. The unit consists of 68 parts and is designed to provide less downtime, long life and low operating costs. Chlorinators Inc.
