A Guide to Steel Surface Preparation with Modul 350 Shot Blaster

Dec 20, 2024 | Blogs

Ships, oil rigs and bridge decks demand precise steel surface preparation to ensure coating success. The Modul 350 mobile shot blaster meets these challenges with smaller shot sizes that strip rust and coatings cleanly from steel surfaces, preventing contaminants from being driven deeper into the substrate.

You can match power output to your specific shot blasting needs with a choice of 15 kW or 18 kW blast wheel motors. Plus, its modular design allows you to double the working width from 350mm to 715mm by adding an extension unit.

Power and performance

The 15 kW version works seamlessly with the R2D2 dust collector, offering a more cost-effective solution for many applications. The 18 kW model pairs with the R2D2-7 dust collector for demanding projects to handle increased material removal rates.

It has a motor rotation speed of 2935/2940 rpm, operating at 25.7/31.4 A, creating the impact force necessary for steel surface preparation.

Magnetic skirts and heavy-duty rubber seals contain the shot and debris, ensuring dust-free operation. The extra-large discharge chute enables quick emptying between passes.

Easy maintenance and longevity

The Modul 350 requires minimal daily maintenance. Consumable items like the blast wheel and shot cage need only basic tools for replacement. All wear liners have quick-change designs, allowing you to handle routine maintenance efficiently.

The machine's modular design concept has been developed over two decades. You can combine different modules to suit your specific requirements, offering flexibility in setup and operation not found in other manufacturer lines.

Versatility in operation

Your operating width starts at 350mm, but you can double it by adding a Modul 350 EU extension unit. The high blast performance makes this machine ideal for:

  • Steel deck preparation
  • Bridge surface renovation
  • Tank interior and exterior blasting
  • Heavy coating removal
  • Industrial floor preparation

The compact dimensions (110 x 185 x 55 cm) and manageable weight (405/415 kg) ensure excellent manoeuvrability in tight spaces. An exclusive "Travel Mode" protects the dust skirts during transportation and loading.

Key specifications

  • Working width: 350mm
  • Power options: 15 kW or 18 kW motors
  • Voltage: 400V
  • Vacuum port: 125mm
  • Weight: 405/415 kg depending on motor
  • Dimensions: 110 x 185 x 55 cm

Cost-effective investment

The Modul 350 stands out for its exceptionally low operating costs and proven reliability. Used machines rarely appear on the market, and when available, they sell within days—a testament to their lasting value and performance.

For steel surface preparation, the machine delivers consistent, high-quality finishes suitable for most coating applications. Its dust-free operation and low noise levels let you work efficiently in various environments, from industrial settings to enclosed spaces.

With minimal training requirements, you achieve high productivity from day one. The combination of reliable performance, low maintenance needs, and exceptional surface finish quality makes the Modul 350 a standout choice for professional steel surface preparation.
