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

  • Huge 72 oz. discharge capacity per cycle
  • Fully pneumatic – no power required
  • Non-clogging, full-port drain valve
  • Heavy-duty construction for industrial use
  • Translucent reservoir for easy visual inspection
  • Isolated magnetic trigger assembly
  • Horizontal low-profile design
  • NPT or BSPP connection options
  • Automatic operation for hassle-free use

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.

Technical Specifications

  • Inlets: (2) 3/4″ NPT (BSPP optional)
  • Outlet: 1/2″ NPT (BSPP optional)
  • Operating Pressure: 0–250 PSI
  • Power Source: Clean, dry compressed air (80–130 PSI)
  • Operating Temp: 32° to 180°F
  • Discharge Volume: 72 oz. per cycle
  • Weight: 22 lbs.
