Drum choice by material
The problem
Renders vs reinforced concrete: a single drum is not enough.
Sept Tools
Écureuil two drums: electrolytic and PCD interchangeable.
Sept Tools

Wall planing is the aggressive vertical stripping operation that takes over when grinding is no longer enough: thick degraded renders, old tile adhesives, accumulated industrial paints, concreting steps to be corrected. Sept Tools offers two brushless solutions dedicated to wall planing and concrete scarifying, each acting as a vertical concrete scarifier for the densest substrates. The Écureuil with its two interchangeable drums (electrolytic for concrete and reinforced concrete, PCD for renders, bituminous coatings and resins) covers the bulk of needs. The Gazellomur Rabot, a tracked carrier, takes over on large surfaces. Key positioning: Sept Tools wall planing relies on attack force, not on feed speed.

IU51
The IU51 is a dual universal bypass motor cyclonic dust extractor. Compact, easy to transport and to handle, it suits confined spaces. Its automatic filter cleaning system works during operation, without operator action, and keeps the airflow constant. Equipped with 2 ULPA+PTFE cartridges (22,000 cm²), an airflow of 340 m³/h and the 22 m Longopac system. Compatible with the Petit Potam, Fouine and Castor.
IU81
The IU81 is a triple-motor cyclonic dust extractor. Its enhanced filter protection against abrasive materials and improved cyclonic effect make it suited to demanding sites. Automatic filter cleaning (also available in manual mode). Equipped with 3 ULPA+PTFE cartridges (36,000 cm²), an airflow of 510 m³/h and the 22 m Longopac system. Compatible with the Petit Potam, Fouine and Castor.
IU200
The IU200 is an industrial dust extractor with automatic filter cleaning and a multi-filter system. It is designed for continuous 24/7 operation. Industrial extraction of fine dust for a clean and safe working environment. Equipped with 5 HEPA + PTFE cartridges (100,000 cm²), a turbine delivering 1,100 m³/h and a large-capacity drum. Compatible with the Petit Potam, Fouine and Castor.

Manual planing / angle grinder
- Manual planing: extreme physical effort
- Angle grinder: dust everywhere, compliance impossible
- One fixed drum: material mismatch frequent
- Vibration above 5 m/s², shoulder MSDs
- Chemical strippers: hazardous waste

Your questions, answered
Écureuil or Gazellomur: when to choose which?
The Écureuil with its two drums covers most wall planing needs, in particular targeted stripping and small to medium surfaces. The Gazellomur Rabot, a tracked carrier, takes over on large continuous surfaces.
Electrolytic or PCD drum: how to choose?
Electrolytic drum for concrete and reinforced concrete: robust attack on dense substrates. PCD drum (polycrystalline diamond) for renders, bituminous coatings, resins and epoxy finishes: clean cut without tear-out.
Why is planing positioned for force and not speed?
Wall planing is the stripping operation for thick and dense substrates. A feed that is too fast reduces the depth of attack and prematurely wears the drum. The Écureuil and the Gazellomur are designed to maximise the applied force, even at the cost of slower advance.
Does the planer damage the concrete substrate?
No, provided the cut depth is set correctly. The drum stops on healthy concrete. Sept Tools provides the setting procedure based on the thickness of the coating to remove.
Can planing and grinding be chained on the same site?
Yes: on the Gazellomur you swap the planing head for the grinding head. For the Écureuil, planing is followed by grinding with the Petit Potam or Gazellomur Ponçage depending on the targeted finish.
