McCann's small 1/3 HP carbonator has a 32 ounce stainless steel tank and injection molded base, 1/4" male flare CO2 inlet, 3/8" male flare water inlet, 3/8" male flare soda water outlet, and brass ASSE 1022 backflow preventor. Flow rate is 100 GPH. 180 PSI. 115V/60HZ motor runs at 1725 RPM, and draws 6.5 amps. McCann’s Carbonators now feature a fully potted probe switch for improved reliability, service call reduction, increased up time, and extended life cycle. This new feature waterproofs the electronic components within the probe which is the most frequently replaced part on the carbonator. Please note that the new “-PP” parts are backwards compatible and can be installed on previous generation carbonators.
