How the Robo Drain Drain Valve Works

Condensation enters through one of two ports
The see-through vessel allows visual inspection of the condensate as it fill the reservoir.
A stainless steel float rises with the condensate and positions a magnetic force over the valve housing.
When the liquid level reaches the desired level, the magnet in the valve housing snaps upward and opening the pilot compressed air valve.
This compressed air is used to actuate the air cylinder causing it to extend and open the ball valve.
Condensation, scale and rust particles rapidly exit the unit. Before any compressed air is lost, the float removes the magnetic force from the valve closing the pilot compressed air valve.
A powerful spring returns the air cylinder to its normal position closing ball valve.

RoboDrain Connections Explained

The photo to the right shows a side view of a RD11-T RoboDrain. The blue cap is where the 1/8 in. needle valve needs to be installed. The needle valve prevents a vacuum from forming in the RoboDrain. If a needle valve is not installed and adjusted a vacuum will form causing condensate to back-up into the air system. The needle valve does bleed a small amount of compressed air to atmoshere. In a year of operation the needle valve will consume about the same amount of compressed air as a standard electronic drain use in a single actuation.

The red cap is one of the 3/4 inch condensate inlets. Pipe your condensate to this port or the other 3/4 inch inlet (not pictured). One of the 3/4 inch inlets needs to be capped off or run the condensate to both inlets.

A needle valve and a cap for one of the 3/4 in. condensate inlets are not supplied. To properly install the RD11-T, please have these items on hand at installation. They are readily available from any plumbing supply house.

The photo to the right shows a close-up of the RoboDrain's control air connection. RoboDrain's operate on compressed air. The 1/4 inch behind the blue cap is where you connect your control air. The RoboDrain requires clean dry air with a pressure between 80 and 120 PSI.

RoboDrain's come standard with an inlet air filter to stop particulate from clogging the drain's pneumatics. At the bottom center of the photo you can see the test button. The test button allows you to acctuate the RoboDrain at any time, testing the drain.

Warranty

The Robo Drain comes with a one year manufacturer's warranty. Specifically, the Rob Drain is warranted to be free from defects in workmanship and materials for a period of one year from the date of shipment. The liability of the manufacturer is limited to repair or replacement of the drain at its option.

Robo Drain No-Loss Design Advantages

The Robo Drain does not use electricity. 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. In most applications, the Robo Drain's design eliminates the need for a vent line. A magnet is used to ensure both a positive opening and closing that prevents air loss. The magnetic force is positioned away from the condensate to prevent attraction of metal particulate. Rifle drilled discharge porting ensures that scale and rust will exit through a full ported 1/2" ball valve. The Rob Drain will not clog and no strainer is required.
