OEL exceeded without capture
Le problème
Without source extraction: concentration 200 to 400x OEL 0.1 mg/m³ over 8 h, enforcement notice.
Sept Tools
IU33 Longopac HEPA H13, capture 99.995 % at 0.3 micron: exposure divided by 50.
Sept Tools
Industrial vacuums for concrete construction sites
Sept Tools class H vacuums for crystalline silica compliance, asbestos abatement and site cleanliness across all trades.
Exposure to crystalline silica dust is now classified as a definite human carcinogen. The French Labour Code imposes strict occupational exposure limits and requires construction companies to install source extraction systems at every emitting station. The Sept Tools vacuum range meets this obligation while simplifying site logistics with the Longopac continuous waste evacuation system. Three models cover every need, from isolated operator stations to centralised multi-machine extraction.

Challenges and solutions
Technical challenges and answers
Asbestos protocol non-compliant
Le problème
SS3 removal: bag opening equals contamination, protocol breach, site shutdown.
Sept Tools
Longopac continuous sealed bagging: zero manipulation, sleeve-by-sleeve traceability.
Airflow insufficient multi-machine
Le problème
Single-station vacuum on workshop: split airflow, lost capture, compliance compromised.
Sept Tools
RU80 65 l/s plus 4-port splitter: airflow preserved per line, class H maintained.
Nuclear audit failed
Le problème
EDF/Framatome audits: minimum HEPA H13, equipment traceability, cleanliness.
Sept Tools
IU33 H13 plus machine logbook delivered: documented audit compliance under 30 min.
Daily cleaning cost
Le problème
Without source capture: 1 to 2 h end-of-shift cleaning, cumulative productivity loss.
Sept Tools
Source Longopac capture: zero additional cleaning, dust continuously bagged.
Makeshift adapter leakage
Le problème
Third-party connectors non-standard: joint leaks, 30 % airflow loss, degraded capture.
Sept Tools
Vacuums sized for Sept Tools brushless machines: airtight IP65 connection.
Use cases

Hospitals and occupied housing
Sensitive sites with zero dust tolerance: schools, care homes, operating hospitals. Source capture plus Longopac: environment preserved, no additional daily cleaning.
Industrial workshops multi-station
RU80: 4 machines connected simultaneously via splitter in fixed workshop or prefabrication. Sectors: automotive, aerospace, nuclear with EDF/Framatome audit compliance.
Frequently asked questions
Your questions, answered
Which vacuum class for construction?
Class H is required for hazardous dust (silica, asbestos, lead). Classes M and L only suit non-hazardous dust. Sept Tools offers exclusively class H to guarantee compliance.
How many machines can be connected simultaneously?
The IU33 Longopac is designed for one operator station. The Turbo7 supports two machines simultaneously. The RU80 reaches four machines via splitter, with acceptable airflow loss on each line.
Does the filter need regular changing?
Yes. The HEPA H13 or H14 filter must be replaced according to the manufacturer's cycle, generally every 12 to 18 months in intensive use. Sept Tools keeps replacement filters in permanent stock.
Is the Longopac an expensive consumable?
A 20-metre Longopac sleeve provides several days of site use depending on dust volume. The cost per cubic metre of dust collected is largely offset by the elimination of manipulation and asbestos protocol compliance.
Does the vacuum support automatic start?
Yes. All our vacuums feature a slave socket linked to the power tool. Start and stop are synchronised, with no operator intervention.
Has the Sept Tools class H vacuum been validated in real asbestos field conditions?
Yes. The IU33 Longopac class H, paired with the Fouine XB165 grinder, was tested on a live NHS hospital site in the United Kingdom: 1000+ m² of textured asbestos coating removed in 4 productive weeks. Independent UKAS-accredited air monitoring confirmed 0.02 f/ml in the operator zone (regulatory threshold 0.1 f/ml, i.e. 5 times below the limit) and a near source result below the 0.010 f/ml limit of quantification. <a href="/en/case-studies/uk-asbestos-removal-hospital-site">Read the full case study</a>.
