- Cost-effective, mobile, and compact
- HAZLOC: no electrical components
- Intended as a 2K entry-level device for many coatings
- Primers / Base coats
- Sprayable lacquers & paints (including water-based)
- Corrosion protection & MIO systems (micaceous iron oxide)
- Low solvent / solvent-free (Benchmark: material dependent)
- Metal/Steel construction, hall construction
- Mechanical & vehicle engineering
- Painting/coating shops, carpentry
Recommended Basic Settings (benchmarks from data sheet)
- Define the variant first: Mixing ratio (1:1 to 6:1) is specific to the version – choose the pump that fits the material specifications.
- Pressure ratio as starting point: depending on the version, approx. 34:1 to 61:1 (benchmark) – use this to plan the air/hydraulic setup and expected material pressure.
- Flow rate per cycle/DS: depending on the version, approx. 96 to 169 cm³ (benchmark) – helps in estimating throughput and tactical spraying speed.
- Material supply: Standard is direct suction; alternatively, 6-liter hoppers for the A and B sides are available as accessories (practical for frequent changes).
- Optional: Conversion to air-assisted airless is provided as a separate kit (manufacturer accessory).
Professional Workflow (5–7 Steps)
- Check material specification: Clarify mixing ratio (e.g., 2:1, 3:1) and pot life/working window – then choose the appropriate DUOMIX variant.
- Select setup: Direct suction for "simple & mobile" or hopper solution if you prioritize clean changes and better accessibility.
- Hose/Gun check: Check for leaks, clean connections, and filter condition (Goal: no air intake, no particles).
- Initial priming & stabilization: Start material flow briefly until both components are applied stably and evenly (no "gulping" effects).
- Spray test surface: Check coverage, flow, and texture – only then proceed to production.
- Production: Adjust spraying speed to throughput/material (use output per DS as a benchmark).
- Orderly stop: End material handling so that there is no unnecessary "restart stress" next time (clean, systematic, without haste).
Troubleshooting: 4 Typical Problems
- Check if the correct mixing ratio variant is being used (1:1 to 6:1).
- Stabilize material supply (for direct suction: ensure uniform suction conditions; use hopper solution if necessary).
- Check system for leaks (unwanted air can make the process unstable).
- Check suction conditions (hose, suction point, material level) – direct suction reacts strongly to "poor suction" in practice.
- Check filters/lines for contamination.
- Coordinate throughput vs. spraying speed (use output per DS as a benchmark).
- Check variant: Pressure ratio is version-specific (Benchmark 34:1–61:1).
- Consider material viscosity and temperature (thick material needs "more reserve" in practice).
- Check options: For certain applications, air-assisted airless via accessory kit may be useful.
- For frequent changes: Plan for a hopper solution (6 liters) instead of direct suction.
- Standardize the changeover process (always same procedure, same sequence).
- Check wearing parts/filters at regular intervals before "unplanned" downtime occurs.
Maintenance (5 Practical Points)
- Visual check for leaks, loose fittings, and "material traces" at critical points after each use.
- Keep filters/lines clean (particles are one of the most common causes of process instability).
- Regularly check suction components (direct suction): hose condition, fit, seals.
- When using accessories (hoppers): Ensure hoppers are clean, lids/transitions are tight so that supply remains stable.
- Complete material handling cleanly before long downtimes to avoid hard deposits.
FAQ for the DUOMIX 230 Mini (Practical)
The DUOMIX 230 Mini is available in fixed mixing ratio variants – from 1:1 to 6:1 (some listed as approximate values).
Both are benchmarks from technical data: The pressure ratio (approx. 34:1–61:1) helps you plan the expected material pressure, while the output per DS (approx. 96–169 cm³) assists in estimating throughput and spraying speed.
Yes – a separate conversion kit is provided for this (manufacturer accessory).
Direct suction is simple and mobile. However, if you change materials frequently or want to work cleaner, 6-liter hoppers (A and B side) are a sensible alternative.
This is a practical advantage in environments where electrical components would be an issue: According to the data sheet, the unit is HAZLOC certified because it functions without electrical components.
