Featuring a vertical centrifugal pump design, the Plenum Series line of low profile condensate pumps features a 1/30 hp thermal protected motor with stainless steel motor shaft. The pump is controlled by a float switch mechanism, which automatically starts and stops the pump. It also includes a high-water level switch, which opens a thermostat circuit when the pump reservoir is full, stopping the production of condensate. The Plenum Series model is available in both 115 or 230 volts.
