Description
RD13 High-Volume Robo-Drain
Large Capacity, External, Pneumatic Condensate Drain – Zero Air Loss
The RD13 Robo-Drain is a fully automatic, high-capacity condensate drain designed for large compressed air systems. Built for zero air loss performance and pneumatic operation, it requires no electricity and is ideal for use with oil/water separators. The RD13 is engineered to handle high volumes of condensate—even in systems prone to rust, scale, or sludge—while saving compressed air and maximizing uptime.
Key Features

Performance Benefits
- Ideal for large compressor installations
- Zero air loss = lower energy costs
- Handles multiple systems with one unit
- Operates reliably even with rust and scale
- Compact profile allows mounting under equipment
- Visual check of fluid level for quick monitoring
- Operates on demand — no wasted cycles or air
- Unaffected by contaminants or dirty environments
How It Works
Condensate enters through one of two 3/4″ NPT inlets. As the translucent reservoir fills, a stainless steel float rises and triggers a magnetic assembly, directing control air to the valve actuator. The full-port valve opens, draining the reservoir. Once emptied, the float drops, the air flow stops, and the valve closes—returning to collection mode. The chop-free, reliable design ensures clean operation with zero clogging or air loss.
