Bristle Blaster® - Surface Preparation Technology For Various Industries

Advantages and Performance of the Bristle Blaster® Technology

  • Removal of corrosion, mill scale and defunct protective coatings with a surface cleanliness similar to SA 2.5 (NACE No.2/SSPC-SP10 to SA 3 (NACE No.1/SSPC-SP5)
    Restores surface to DIN EN ISO 8501-1 / SA 2.5 to SA 3.
  • Surface texture / Anchor profile up to 120µm (Rz) / 4.72 mils
    Roughness capability from 40- 120µm Rz / 1.57 - 4.72mils . Also in areas where blasting is not permitted. Applies for non-ferrous metals as well.
  • Improved integrity of treated surfaces
    Generates compressive residual stress along treated surfaces providing crack growth resistance, improved fatigue life, and improved corrosion resistance.
  • Negligible heat generation
    Surfaces free of thermal damage and/or heat marking.
  • Eco Friendly
    GREEN surface preparation, does not use/produce hazardous materials. Low energy requirements.
  • Simple and Economical
    Eliminates the need for complex and costly abrasive blast equipment. Benefits include:
    • no recycling costs for contaminated blasting abrasives
    • avoidance of major transport costs of the blasting abrasives
    • rapid commissioning
    • continuous in-service operation due to ergonomic low system vibration (Vibration test)
  • Safety
    • Low vibrations (Vibration test)
      Continuous use of the tool for a number of hours per day is possible due to the low levels of vibration from the tool. There is no risk to operator health resulting from Hand-Arm Vibration Syndrome (HAVS).
    • No costly protective clothing required
      It is not necessary to wear costly protective clothing, as is needed when blasting, due to the low operation speed of the tool of 2300 rpm. Only safety glasses, gloves and a face mask are required for safe operation.
    • A light and ergonomic design allows continuous operation with minimal fatigue
    • Low noise levels
      A sound pressure level (SPL) of a maximum of 83.2 dB(A) is reached during operation. Compare this to other rust removal systems sometimes capable of achieving a sound pressure level in excess of 95db(A).
    • ATEX approved for use in zone 1(Bristle Blaster® Pneumatic) according Ex II 2G c IIA T4 X
      Ex = examination certificate according to RL 94 / 9 / EG (examination done by GEXCON). The meaning is Ex-proof equipment for non-mining applications. II 2G = the equipment is category 2 equipment (zone 1) allowed to be used in potentially explosive atmospheres caused by flammable gases, vapour or mists. Being allowed to work in zone 1 means also beeing allowed to work in zone 2 having in mind that the equipment is allowed to be used in category group 2 and 3 (2G and 3G). c = stands for non-electric tools, constructional safety. IIA T4 = the explosion subgroup is IIA and the temperature class is T4 (max. surface temperature 135°C). It is are also allowed to work in explosion subgroups IIB and IIC making sure not violating the temperature class. This implies that the equipment cannot be used for gases with auto-ignition temperatures below 135°C. Such equipment can be applied for any gas or vapour which has an auto-ignition temperature higher than 135°C, i.e. methane and hydrogen; considering surface temperatures only. X = indicates that the equipment is subject to special conditions for safe use specified in the schedule to the certificate / declaration of conformity (these are, i.e. the materials excluded in the declaration of conformity).

Functionality of the Bristle Blaster® Technology

The rotating bristles are dynamically tuned to the power tool resulting in an impact and immediate retraction of the bristle tips from the working surface (see video below).

The bristle tips are designed to strike the corroded surface with a kinetic energy that is equivalent to grit blast media, thereby generating a texture and visual cleanliness that mimics the grit blasting process.

The results of further independent studies about the Bristle Blaster® Technology can be found in Press.
