On a concrete grinding, renovation or asbestos removal jobsite, the class H construction vacuum is not an accessory: it is the component that decides whether dust is captured before it reaches the operator. A class M vacuum is no longer enough once crystalline silica or asbestos is involved. At Sept Tools, the IU33 Longopac and the IU51 are declared class H to EN 60335-2-69 annex AA; the IU33 Longopac, the one we recommend for asbestos, adds HEPA H14 filtration (99.995% at 0.12 µm, MPPS): capture at the source at the grinder plate, continuous Longopac bagging with no operator contact, designed for the real jobsite, not for the sales sheet. Sept Tools-branded machines designed and assembled in Roanne, after-sales in Roanne.
The machines below are selected for this application: dust captured at the source and anti-MSD design. Quote within one working day.

The IU33 Longopac is our class H construction vacuum for HEPA H14 source capture. 1100 W, 25 kg, 200 m³/h flow. Longopac continuous bagging system: the full bag is sealed and separated without exposing the operator to the collected dust. Compatible with all our machines except the Castor and Ceiling Planer planers. Source capture of crystalline silica. EN 60335-2-69 annex AA. Roanne, after-sales diagnosis within 48 working hours.
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.
Filtration efficiency at 0.12 µm (MPPS) of the HEPA H14 filter of the IU33 Longopac.
Continuous sealed bagging: the operator never touches the captured dust when changing the sleeve.
The IU33 Longopac and the IU51, declared class H to EN 60335-2-69 annex AA.
HEPA H14 at 99.995% (0.12 µm, MPPS), IU33 Longopac classified H to EN 60335-2-69 annex AA; manual, technical data sheet and the manufacturer's EC declaration of conformity supplied.
Direct connection to the plate of Sept Tools grinders, planers and drills. Dust is captured before it falls on the operator, not sucked from the ambient air afterwards.
On the IU33 Longopac, continuously sealed plastic sleeve for contact-free emptying with no re-suspension.
Automatic filter cleaning maintains the negative pressure and the air flow throughout the session, with no manual stop.
You describe the context: crystalline silica, asbestos sub-section 3 or 4, lead, surfaces, tools to connect. We identify the filtration level and flow required.
IU33 Longopac, declared class H, for silica and asbestos. IU51, also declared class H, for a higher flow. IU40, IU81 and IU200 for compact mobile or high flow: their manuals do not declare class H.
Connection to grinders, planers and drills, choice of filters (HEPA + PTFE, H14), Longopac consumables, adapters. Everything is sized for source capture.
We draw up a priced quote that builds in the return on investment: reduction in jobsite stoppages and, depending on profile, prevention equipment fundable under conditions, subject to prior approval by your insurance fund before purchase.
Delivery with manual, technical data sheet and the manufacturer's EC declaration of conformity.

Grinding a concrete slab without suitable extraction pushes crystalline silica above the 0.1 mg/m³ OEL: carcinogenic exposure and risk of a labour inspectorate citation.
The IU33 Longopac class H, connected at the source at the plate, captures the fines before they fall. Exposure is verified by measurement on the jobsite.
Without source capture, asbestos fibres disperse in the confined zone, despite the 10 Pa negative pressure.
The IU33 Longopac class H captures at the source and discharges into a sealed sleeve. Operator exposure at emptying is reduced; it is verified by measurement on the jobsite.
Manual emptying of a tank-type vacuum directly exposes the operator to the accumulated fibres and dust, wiping out the benefit of upstream filtration.
The Longopac system seals the dust in a continuous plastic sleeve.
On a class M vacuum or an undersized unit, filter clogging makes the negative pressure drop, and source capture loses its efficiency before the end of the shift.
The automatic cleaning of the IU33 Longopac, IU51, IU81 and IU200 maintains the flow. The IU81 and IU200 provide the power reserve for long sessions.
Without equipment documentation, justifying the class H of a vacuum during an inspection or an OEL measurement becomes an administrative headache.
The IU33 Longopac, the Sept Tools class H vacuum, is supplied with its manual, its technical data sheet and the manufacturer's EC declaration of conformity.
In a confined zone at 10 Pa negative pressure, the IU33 Longopac provides source capture and sealed bagging. HEPA filtration, contact-free emptying: the operator in full PPE does not handle the captured dust.
Coupled to a floor, wall or ceiling grinder, the class H vacuum captures crystalline silica directly at the plate. On raw concrete, source extraction is part of the user's protection; exposure is verified by measurement on the jobsite.
Connected to the drill, the class H vacuum extracts dust at the source, for a clean hole ready to receive the resin. The cleanliness of the drilling determines the pull-out resistance of the chemical anchor and the validity of the ETA technical assessment.
The IU81 and IU200 cover large-scale jobsites, where a high air flow has to be supplied. The range scales up in power without changing the capture logic. Their manuals do not declare class H: for silica and asbestos, the IU33 Longopac remains the reference.
