The ROBO DRAIN RD750 is the
ultimate, High Pressure, demand operated drain.
The unit is fully automatic, no electricity is required. Its low
profile gives you the advantage of installing it in areas where the
vessel to be drained is only a few inches from the ground. A unique
air valve design uses a magnetic force to ensure both a positive
opening and closing that will prevent any air loss.
The magnetic force is cleverly
positioned away from the condensation level to prevent any
attraction of metal particulate. An innovative ball valve support
and positioning system prevents the sideloading problem which
otherwise would cause premature sealing failure around the valve
stem. 1/2" ball valve ensures that scale and rust will exit the
vessel. The ROBO DRAIN RD750 will not clog ---- no
