The technology

Simultaneous removal & profiling

Overview

Bristle Blasting technology simultaneously removes corrosion and generates anchor profile . Consequently, surfaces that have been treated by Bristle Blasting have a texture and visual cleanliness that mimics those obtained by traditional grit blasting processes. The Bristle Blaster® Pneumatic Double delivers twice the impact for fast, even surface preparation – efficient, controlled, and uncompromisingly powerful against rust. Removes corrosion, coatings, mill scale and other contaminants - without removing healthy material Generates anchor profiles ranging from 2,5 to 3,3mil also on weld seams, edges, around bolts and on surface irregulariti

FAQ

What results does the Bristle Blaster® Technology deliver?
The patented Bristle Blaster ® Technology is capable of removing corrosion and coatings quickly and thoroughly. At the same time, the Bristle Blaster ® creates surface preparation grades comparable to ISO 8501-1 Sa2 ½ & Sa3 and roughness levels of up to 120 µm R z . Example: Roughness levels of 65–83 µm were achieved on a pipe made of API-5L-X42 steel with rust grade D.
What is the working speed of the Bristle Blaster®?
The working speed of the Bristle Blaster ® depends on the following factors: Hardness and quality of the base material Rust grades present (A, B, C, D) Coatings applied (type, thickness) Scale layer Adhesive residues Example: A working speed of 1.1 m² per hour was achieved on a pipe made of API-5L-X42 steel with rust grade B.
How long is the service life of a Bristle Blaster® Belt, an Accelerator Bar and an Adaptor System?
The average service life of a Bristle Blaster® Belt is approximately one hour which is about 1 – 1.5 m 2 of the surface. Light flashrusted surfaces can be treated at a rate of 1.1 m 2 per hour. On some applications e.g. surface preparation on plain weld seams, not coated, construction steel etc. even lifetime of Bristle Blaster ® Belts up to 3 m 2 has been experienced. We rough…
What applications are Bristle Blaster® Belts made of stainless steel used for?
Bristle Blaster ® Belts made of stainless steel are used exclusively to prepare nonferrous metals, such as aluminum and stainless steel . Together with the matching Accelerator Bars made of stainless steel, they prevent the surface being prepared from becoming contaminated and the contact corrosion this would lead to.
Can I also use Bristle Blaster® Belts on other drive units?
No! Bristle Blaster ® Belts can only be used on MONTI’s Bristle Blaster ® Pneumatic and Electric drive units. These drive units are equipped with an Accelerator Bar that increases the kinetic energy of the bristles many times over. What’s more, they are specially matched in respect of speed and torque for use with Bristle Blaster ® Belts. Bristle Blaster ® Belts only produce th…
Why is the compressed-air supply so important to the functionality of Bristle Blaster® Technology?
The Air Pressure Regulators supplied with the set regulate the optimum operating pressure and therefore the rotational speed of the Bristle Blaster ® . If this speed is too fast, the individual bristle tips cannot strike the base material properly: All they do is scrape across the surface and they fail to generate the necessary surface roughness. The Air Pressure Regulators inc…
What servicing work does the Bristle Blaster® need?
Pneumatic The compressed-air motor of the Bristle Blaster ® Pneumatic must be lubricated every time before it is used. All you have to do is put a few drops of low-viscosity oil into the compressed-air connection. Proper lubrication ensures that the tool enjoys a longer service life and is a precondition for warranty claims. Electric This tool should only be serviced by special…
Why has my Bristle Blaster® band torn?
If a Bristle Blaster ® Belt tears at the seam, it has probably be used together with a worn adapter system. As time passes, this forms a sharp edge at the webs that connect the two shells. These sharp metal edges can cut the seam and destroy the belt. Consequently, an adapter system should be replaced after approximately 50 operating hours.

The patented mechanism

Simultaneous removal & profiling, in one pass

STEP 01

Impact

Bristle tips strike the surface at kinetic energy comparable to abrasive grit-blast media.

STEP 02

Accelerator bar

The patented accelerator bar amplifies tip impact for maximum removal efficiency.

STEP 03

Retraction

Tips retract instantly, creating the anchor profile without smearing, burnishing or heat.

STEP 04

Coating-ready

A clean, profiled, grit-free substrate, comparable to abrasive blasting, 65–85 µm Rz (2.6–3.3 mil), ready to coat.

Bristle Blasting vs. grit blasting

Same result. None of the downsides.
