In shipyards and boatyards, there is no single industrial vacuum cleaner suitable for every process. Sanding fibreglass, removing antifouling coatings, sanding fillers, abrasive blasting, cutting composites and mechanical maintenance generate fine dust, abrasives, solids, liquids, oils and swarf with different characteristics. The choice must consider the material, quantity produced, extraction point, hose length, work continuity, filtration and any ATEX classification. In many yards, several solutions are therefore required, each configured for a specific activity.
Industrial extraction in shipyards and boatyards
The construction, maintenance and refitting of a vessel include operations carried out on hulls, decks, superstructures, metal components, systems, technical rooms and internal areas. Activities may take place in a workshop, inside sheds, on external scaffolding, directly on board or in narrow and confined spaces.
The most frequent residues generated in the yard include:
- ✓ Fibreglass and composite-material dust
- ✓ Filler, primer, gelcoat and paint dust
- ✓ Residues from antifouling coating removal
- ✓ Spent abrasive and blasting grit
- ✓ Sawdust and structural wood dust
- ✓ Water, damp dirt and bilge spillages
- ✓ Oils and emulsions from mechanical workshops
- ✓ Welding fumes and airborne particulate
These contaminants must not be managed with the same machine. A model for extremely fine dust must not come into contact with water or heavy abrasives. Likewise, a multi-purpose machine for solids and liquids is not structurally suitable for continuous, intensive composite sanding.
Why a generic vacuum cleaner may not be sufficient
The operating conditions of a boatyard change significantly from one working phase to another. During hull sanding, the objective is to capture volatile dust directly from the power tool, while after abrasive blasting it is vital to move heavy, abrasive granules across large surfaces. A non-specific configuration quickly shows severe limitations:
The most common problems and risks linked to an inadequate choice:
- Rapid filter clogging and immediate airflow collapse at the tool;
- Dispersion of toxic or irritating dust into the operator’s breathing zone;
- Build-up and deposition of heavy grit along ducts and hoses;
- Premature wear of internal components caused by abrasive materials passing through;
- Immediate contamination of cartridge filters in contact with water or damp bilges;
- Major handling and logistical difficulties in narrow on-board spaces.
For this reason, parameters such as airflow, vacuum pressure, filter surface area, cleaning system and collection method must be calibrated together according to the actual hours of use in the working cycle.
How to configure the suitable system in the yard
The correct engineering of the extraction system is based on a three-dimensional analysis of the work to be carried out. These are the FEVI guidelines for an error-free choice:
1. Process analysis: extraction at source vs subsequent cleaning
Capture at source intercepts the dust by connecting directly to the tool shroud, such as sanders, composite saws and planers, significantly reducing the dispersion of fibreglass or antifouling dust into the air. Subsequent cleaning instead acts on residues already deposited on the floor, scaffolding or hulls, requiring wide floor accessories and collection drums that differ from those used for work connected directly to the tool.
2. Particle-size identification and chemical hazard of the residue
The term “yard dust” is misleading. Fibreglass or carbon dust requires very high-efficiency filter media and anti-clogging treatments. Blasting grit instead requires strong vacuum pressure and anti-wear deflectors. Finally, mechanical removal of old protective coatings or antifouling coatings can release toxic chemical compounds. In these scenarios, the safety data sheets must be analysed to integrate absolute HEPA filters and sealed discharge bags.
3. Hose length, produced volume and motorisation: single-phase vs three-phase
In shipyards, distances are significant and hoses often run vertically along hulls and scaffolding: strong vacuum pressure is required to compensate for unavoidable pressure losses. Hourly volumes determine motorisation: compact single-phase machines are ideal for intermittent work and agile movement on board, while industrial sanding on large hulls or permanent multi-operator workstations require a three-phase side-channel blower designed for continuous cycles.

Operational focus on refitting and construction activities
The modern boatyard is an ecosystem of heterogeneous processes, each requiring a specific configuration:
- Sanding fibreglass, fillers and gelcoat: Produces extremely fine, highly clogging dust. If the filter is not cleaned constantly, suction performance drops. Pneumatic or timed systems help keep yard performance stable.
- Collecting abrasives from hull blasting: Grit and spent sand are very heavy. They require very high-vacuum configurations combined with cyclonic pre-separators, which intercept granules before they reach the main filter chamber, significantly reducing wear.
- Bilges and damp on-board cleaning: Process water, washing residues and muddy residues require shut-off floats and stable Wet&Dry drums, taking care never to convey petrol, solvents or flammable fluids into standard machines.
- Engine workshops and mechanical maintenance: For shaft, gearbox and pump maintenance, land-based workshops require the OIL range to isolate filings and metal swarf while recovering coolant fluids.
First recommended FEVI model: FEVI 220 ICLEAN
For sanding, filler sanding and dry cutting operations carried out on board or in the workshop with a single power tool, the FEVI 220 ICLEAN is the first professional starting point to assess.
Powered at 230 V, it features two powerful by-pass motors and an advanced HEPA + PTFE filtration system. Its compact structure and low weight, 36 kg, make transport through narrow vessel passageways easier. The real strength for refitting is the automatic ICLEAN cleaning system, which cyclically cleans the filters without interrupting the extraction flow, helping prevent fibreglass dust from saturating the machine.
When the yard requires specialised solutions
The 220 ICLEAN model responds to single-phase fixed sanding requirements, but nautical logistics often require vertical configurations:
The most frequent mistakes to avoid in the nautical sector
- The single-machine logic: Expecting the same single-phase industrial vacuum cleaner to collect fine gelcoat dust, bilge sludge and large quantities of blasting grit will damage motors and saturate filters in a short time.
- Vacuuming only at the end of the job: Allowing fibreglass dust to disperse and then collecting it from the floor is inefficient. Real prevention is achieved by setting up correct capture at source directly on the tool.
- Underestimating hose diameters: Hoses that are too long or too narrow choke the airflow, causing heavy abrasive residues to accumulate in elbow bends and blocking the work.
FAQ on extraction in shipyards and boatyards
Which vacuum cleaner is required for fibreglass dust and antifouling coating removal?
An industrial vacuum cleaner for fine dust is required, equipped with certified filters, such as HEPA/PTFE, and, above all, with a continuous automatic cleaning system. To protect operators, antifouling coating and fibreglass must be extracted directly from the sander shroud at source. For safer disposal with reduced dispersion, the PULSE range with Longopac continuous bag is the most suitable choice.
Can a common vacuum cleaner collect sand and grit from abrasive blasting?
No. Spent grit and blasting residues are extremely heavy and highly abrasive. They require specific high-vacuum machines, such as the BT series, reinforced flexible hoses and cyclonic pre-separators to separate granules before the filter chamber. High-airflow dust collectors for airborne dust are not suitable for this purpose.
When is an ATEX-certified machine required in a boatyard?
An ATEX configuration is required when the risk assessment identifies the concrete possibility of explosive atmospheres forming. This can occur in the presence of high concentrations of combustible plastic or metal dust in confined spaces, or where flammable vapours from painting or resin application may accumulate.
What is the practical difference between an industrial vacuum cleaner and a dust collector in the nautical sector?
The industrial vacuum cleaner uses vacuum pressure to drag solids, liquids, abrasives or dust through flexible hoses and brushes. The dust collector moves large volumes of air, with high airflow and low pressure, to capture extremely fine airborne dust through hoods, articulated arms or booths, filtering the air before it is returned to the environment.
