The FEVI BSL 120 BASIC ATEX 22 model provides an excellent solution for localised vacuuming requirements in industrial environments where there is an explosion risk due to the presence of combustible dust. The unit is classified with the official marking II 3D Ex h tc IIIB T135 °C Dc.
Category 3D identifies equipment specifically intended for use in external Zone 22, where the formation of an explosive atmosphere caused by combustible dust clouds is not expected during normal operation or may occur only occasionally and for limited periods.
The internal filtration and collection chamber is instead fully designed and configured to support internal Zone 20, safely managing the high dust concentrations generated during operation.
Ideal Application: Designed for agile operations and localized cleaning of industrial floors or machinery in facilities with tight and narrow layouts.
Key Advantages: 1200 W brushless technology that eliminates carbon brush wear and sparks, combined with isolated motor exhaust via completely filtered airflow.
Model Selection: High-performance single-phase (230 V) and 31.5 kg configuration, ideal if you need maximum maneuverability combined with high vacuum performance (360 mBar).
Not Suitable For: Specialist configuration dedicated exclusively to dry dust. It is not suitable for vacuuming liquids, ATEX gas zones (3G), or external Zone 21 environments.
Safe Engineering: Entirely built in heavy-duty AISI 304 stainless steel (lid, chamber, and 20-liter quick-release drum) to guarantee maximum equipotential bonding.
Filtration & Flow: 50 mm tangential inlet to enhance the cyclonic separation effect, paired with a 13,000 cm² Class M antistatic star filter and an integrated manual shaker.
The BASIC industrial vacuum cleaner range is constructed using conventional filtration systems commonly available on the market, based on woven or non-woven polyester pocket or star filters.
This range offers the advantage of being suitable for a wide variety of general applications, providing companies with considerable operating flexibility. However, careful configuration is required when dealing with complex, fine or airborne dust to prevent rapid filter clogging.
Who it is recommended for
FEVI BSL 120 BASIC ATEX 22 is suitable for companies and professionals who need to perform localised vacuuming operations in the presence of combustible dust and require a compact, easily transportable single-phase machine equipped with a high-efficiency brushless motor and stainless-steel drum. It is suitable for applications in the food, chemical, pharmaceutical, plastics and manufacturing industries, as well as for routine industrial maintenance. Suitability must not be determined solely according to the industry: the zone classification, particle size, resistivity and actual operating conditions of the dust must always be assessed.
Main applications
Collection of combustible dust
Specifically intended for collecting combustible dust compatible with the II 3D Ex h tc IIIB T135 °C Dc marking. Selection must take into account precise physical and chemical parameters: particle size, dust-cloud or dust-layer ignition temperature, minimum ignition energy (MIE), electrical resistivity and explosion class (St). Before defining the configuration, we assess the material safety data sheet together.
Localised collection of dry residues
The 50 mm tangential inlet allows the collection of dust, granular material and small dry solid residues compatible with the hose. The model is not designed for liquids: all communication and use should remain focused on dry residues and localised cleaning of industrial machinery or floors.
Cleaning industrial plants and departments
The compact structure makes it easy to position the industrial vacuum cleaner close to the workstation to collect dust deposited on machinery, structures, dosing stations, bases and packaging lines. The hoses, fittings, lances and nozzles used must be conductive or antistatic to preserve the electrical continuity of the system.
Flexible operation in confined spaces
The compact dimensions of just 55 × 58 × 100 cm make it possible to move and store the industrial vacuum cleaner even in departments with restricted layouts or narrow corridors. The low empty weight of only 31.5 kg and the robust wheeled structure with handle facilitate rapid manual transfer between different operating areas.
Why choose FEVI BSL 120 BASIC ATEX 22
Upgraded 1,200 W brushless motor: The single-phase bypass vacuum unit uses brushless technology without carbon brushes. This eliminates the source of mechanical wear and the sparking associated with conventional commutator motors, ensuring full consistency with use in ATEX Zone 22 and a stable current draw of 6 A.
High performance in a compact format: The updated configuration provides an airflow of 240 m³/h and a high vacuum pressure of 360 mBar, representing a clear performance improvement compared with the previous 800 W FEVI motor.
Tangential inlet and cyclonic effect: The 50 mm tangential inlet introduces the airflow laterally into the 400 mm filter chamber, generating a rotating movement that separates heavier particles into the drum before they reach the filter. This provides greater protection for the filter and extends its service life.
Antistatic Class M filtration: The 13,000 cm² primary polyester star filter is certified as Class M and has antistatic properties. Cleaning is carried out manually using the dedicated external mechanical lever while the machine is switched off.
Optional secondary HEPA filter: For applications requiring the highest level of purity in the air discharged into the environment, a secondary absolute HEPA filtration stage can be installed as an optional accessory.
AISI 304 stainless steel and 20-litre drum: The filter chamber and collection drum are entirely manufactured from stainless steel to provide mechanical strength and equipotential continuity throughout the system. The 20-litre container has a quick-release system for prompt emptying in accordance with company procedures.
Technical Comparison and Technology Selection
The correct industrial vacuum cleaner must be selected according to the type of power supply available within the facility and the continuity required by the operating cycle.
1. Difference compared with FEVI WT 753 BASIC ATEX
The WT 753 BASIC ATEX model is a three-phase unit equipped with a side-channel blower for prolonged operation, a high-capacity 75-litre drum and a versatile central inlet with a deflector for liquids. The BSL 120 instead meets requirements for maximum mobility, a 230 V single-phase power supply, compact dimensions, a brushless motor specifically intended for dry dust and localised collection in a 20-litre drum.

|---|---|---|
| BSL 120 BASIC ATEX 22 | Single-phase electric power supply (230 V) – 1,200 W brushless motor. | 50 mm tangential inlet. Specifically designed for localised dry-dust collection and mobility in confined spaces. |
| WT 753 BASIC ATEX | Three-phase electric power supply (400 V) – 2.6 kW side-channel blower for prolonged operating cycles. | 70 mm central inlet with deflector. Versatile configuration for the combined collection of compatible solids and liquids. |
| S PN ATEX (Venturi Range) | Pneumatic power supply (compressed air at 4–6 bar) – Venturi generator without electrical components. | 60 mm tangential inlet. Ideal for industrial operations where electricity should be completely avoided or where a 1,500 l/min compressed-air network is available. |
Guidelines for safe use
The brushless motor reduces electrical ignition sources, but ATEX safety requires constant control of mechanical and electrostatic factors. Before switching on the machine, the operator must verify the full efficiency of the grounding chain, the equipotential bonding of all metal sections and the exclusive use of certified conductive flexible accessories. Hot materials, embers or glowing substances capable of acting as a direct ignition source inside the drum must never be collected.
