Ceiling grooving is the critical step of routing networks inside suspended ceilings and soffits. Tertiary electrical cables, suspended HVAC lines, fibre optics, home automation: every recessed metre goes through a ceiling chase. Done manually with an angle grinder or chisel, the operation is punishing, loud and exposes the operator to silica dust. Sept Tools offers a dedicated machine: the RAI102834 Ceiling Groover, a Desman head on an articulated arm, paired with an Eland or Gazelle trolley to absorb the weight. The operator guides the machine without carrying it, a gas strut pushes the arm to keep the head pressed against the ceiling, and source extraction limits exposure to silica dust; a P2 mask remains mandatory and exposure is assessed on site.

Rainureuse plafond
The Sept Tools Ceiling Groover takes the head of the Desman groover and mounts it on an arm designed for ceilings. It pairs with an Eland or a Gazelle trolley: the operator guides the groove instead of holding the machine overhead. Same grooving capacity as the Desman, up to 50 mm wide and 50 mm deep, brushless motor with no carbon brushes. The guard connects to a class H vacuum; overhead, a P2 mask remains mandatory. Maximum grooving height: 3 m.

IU81
The IU81 is a triple-motor cyclonic dust extractor, the market reference in terms of durability. Its enhanced filter protection against abrasive materials and improved cyclonic effect make it the high-performance solution for 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. Designed for continuous 24/7 operation with no maintenance, it offers exceptional durability. Industrial extraction of fine dust for a clean and safe working environment. Equipped with 5 ULPA+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 ceiling grooving / angle grinder
- Raised arms: 1 hour max before acute MSD
- Manual angle grinder: extreme noise and dust
- Silica dust falling on the operator
- Irregular trace under fatigue, slow patching
- Ceiling chases: operation dreaded on site

Challenges and solutions
Which challenges, and how to solve them?
Desman weight overhead
The problem
Chaser held overhead, above the head.
Sept Tools
The arm and the trolley carry the weight: the operator no longer holds the machine.
Falling silica on operator
The problem
Ceiling fines falling on the operator's face.
Sept Tools
IU33 Longopac HEPA H13 source capture 65 l/s, P2 mask mandatory.
Trace deviation under fatigue
The problem
Ceiling chase manual: trace deviates after 30 min, double patching cost.
Sept Tools
Articulated arm guiding plus constant torque: clean trace in series.
Fixed balancer limited mobility
The problem
Fixed compensator: small working area, frequent repositioning.
Sept Tools
Articulated arm on an Eland or Gazelle trolley: the trolley moves fully equipped, without dismantling, from one area to the next.
MSD absenteeism improvised set
The problem
Non-dedicated setup: 60-day MSD absence per year, throughput degraded 40 %.
Sept Tools
Sept Tools dedicated architecture: payback 6 to 10 months, sustained throughput.

Frequently asked questions
Your questions, answered
Why a dedicated ceiling set?
Manual ceiling grooving quickly hits physical limits: raised arms, weight of the Desman, cumulative fatigue. The RAI102834 Ceiling Groover, on an articulated arm with an Eland or Gazelle trolley, turns this punishing operation into a guided motion: the operator no longer carries the machine, and strain is reduced.
How does the ceiling arm work?
The arm of the RAI102834 Ceiling Groover pivots on a plate at the top of the trolley mast, and a gas strut pushes it to keep the Desman head pressed against the ceiling on its rollers. The operator guides the feed with the handle without carrying the load.
What is the maximum ceiling depth?
The RAI102834 Ceiling Groover, with its Desman head, reaches 50 mm deep and 50 mm wide in a single pass (up to 3 Ø 230 mm discs), sufficient for almost all ICTA conduits, multilayer tubes and standard cable runs. With 4 discs, the width stays limited to 50 mm and the 50 mm depth is reached in two passes.
Can reinforced concrete be grooved in the ceiling?
Yes, with suitable diamond blades. On dense reinforced concrete ceilings, throughput is roughly 25% lower than on a standard concrete ceiling. Radar rebar detection is recommended to avoid snags.
Payback period for a tertiary electrician?
For an electrician running regular tertiary renovations with recessed ceiling networks, the ceiling grooving set pays back in 6 to 10 months. Payback comes from time savings and reduced strain.
