Ceiling bush hammering combines the strain of overhead work with that of manual bush hammering. Raised arms, machine weight, vibration, dust falling straight back onto the operator: impossible to sustain over a full day without dedicated equipment. Sept Tools offers two brushless ceiling sets equivalent in throughput. The Gazelle set (Gazelle + IU33 Longopac + Fouine XB165) for standard sites with built-in class H extraction. The compact Eland set (Eland + Fouine) for sites constrained on size. Both deliver native strain relief that lets the operator hold a full shift.

Your questions, answered
What is the difference between the Gazelle set and the Eland set?
The Gazelle set (Gazelle + IU33 Longopac + Fouine XB165) bundles class H extraction as standard: ideal for sites where silica compliance is critical. The Eland set (Eland + Fouine) is more compact and easier to handle on sites constrained on size: the class H vacuum is connected separately.
Why use the Fouine rather than a dedicated bush hammer?
The versatile Fouine XB165 lets you chain grinding and bush hammering on the same site with a simple drum swap. For a ceiling contractor, a single versatile machine is more profitable than a fleet specialised by use.
Can grinding and bush hammering be chained on the ceiling?
Yes. The Fouine XB165 accepts the grinding drum and the bush hammering drum. The swap takes under two minutes. The operator chains both operations on the same site without changing machine or trolley.
Which extraction for ceiling silica compliance?
The IU33 Longopac class H HEPA H13 is integrated into the Gazelle set. It complies with the French OEL of 0.1 mg/m³ for crystalline alpha-quartz silica. In Eland configuration, the IU33 is connected separately.
Which size to choose for a constrained site?
The Eland set is designed for low ceiling heights and restricted access. Its compact size lets it pass through standard corridors and door frames. The Gazelle set is bulkier but bundles the vacuum.
