Description

RD11-Vac Robo-Vac – External Pneumatic Operated Condensate Drain for Vacuum Systems

The RD11-Vac Robo-Vac is a fully automatic, zero-loss condensate drain engineered specifically for vacuum systems, operating efficiently without electricity. Its translucent reservoir allows quick visual assurance of operation, while its rugged, industrial-grade design ensures dependable service in demanding environments. Designed to handle vacuum levels up to 26″ Hg, the RD11-Vac Robo-Vac is ideal for protecting equipment and maintaining peak system performance.

Specific to Model:

• Inlets: (2) 3/4″ NPT (BSPP connections available)
• Outlet: 1/2″ NPT (BSPP connections available)
• Power: Clean, dry compressed air (80–130 PSI)
• Pressure Range: 26″ Hg vacuum to 90 PSI
• Operating Temperature: 32° to 180°F
• Weight: 17 lbs.
• Discharge Volume: 24 ounces per cycle

Key Features

• Complete drain system for vacuum applications
• Fully pneumatic – no electrical connection needed
• Isolated trigger assembly for positive operation
• Heavy-duty industrial construction
• Horizontal low-profile design fits in tight spaces
• Non-clogging, full-port drain valve handles rust and scale
• Translucent reservoir for easy inspection
• NPT or BSPP connections for installation flexibility

Benefits

• Designed for most vacuum systems
• Reliable – unaffected by contaminants and debris
• Works across multiple compressed air systems, saving air and lowering costs
• Quick-check reservoir for instant level monitoring
• Handles scale and rust without clogging
• No electricity required, reducing installation complexity
• Operates on demand for energy efficiency

How It Works

Condensate enters through one of two inlet connections. As the reservoir fills, a stainless steel float mechanism rises to a preset level, activating the isolated magnetic trigger assembly. Control air is directed to close the pinch valve and balance line valve, isolating the drain from the vacuum system. Air is then sent to the drain valve actuator, opening the full-port drain valve and pressurizing the reservoir to discharge condensate. When emptied, the float drops, closing the air line, sealing the drain valve, and reopening the pinch and balance valves—returning the RD11-Vac Robo-Vac to collection mode.
