Industrial blower solutions for cleaning vehicle interiors, available for dry residues, mixed materials and liquids.
At car washes, the industrial vacuum cleaner is used repeatedly by customers or operators to collect a wide variety of materials from vehicle interiors. Mats, seats, carpets, boots and load compartments may contain: dust, sand, soil, hair, pet hair, crumbs,

small fragments, leaves, solid residues, damp dirt and limited quantities of liquids. A conventional professional machine may be suitable for controlled use by an operator. A self-service station instead requires a specific configuration designed for frequent use by different people, with a protected structure, timed operating cycles, simplified access to the container and an integrated filter-cleaning system.
Compatible FEVI industrial vacuum cleaners for operator-controlled use
The following models are suitable for professional car washes and detailing centres where the machine is operated and managed directly by personnel. They do not replace a purpose-designed outdoor self-service station.
Criteria for configuring the vacuum system
The optimal configuration of the vacuum stations must be defined by analysing three principal functional areas:
1. Usage Flow
Assessment of the total number of stations required, the average duration of each individual cycle and the frequency of daily public use.
2. System Variables
Calculation of the total flexible-hose length, pressure losses, available electrical supply, whether 230 V or 400 V, and the installation space available.
3. Management Logistics
Definition of drum-emptying procedures, the predominant type of dirt, whether dry or damp, and the frequency of maintenance operations.
Nature of the residues collected from vehicle interiors
Dust and road sand: Sand and soil accumulate in significant quantities inside vehicle carpets. Sand has a higher bulk density than ordinary dust and requires adequate vacuum pressure, piping with a suitable diameter, unrestricted flow paths, a durable container and protection preventing direct impact on the filter. When the flexible hose is very long, the vacuum pressure available at the nozzle becomes the most important parameter for maintaining conveying force.
Hair, pet hair and fibres: Hair and textile fibres tend to adhere electrostatically to seat fabrics and can accumulate inside the piping. In this scenario, actual performance depends on the geometry of the nozzle, inlet air velocity, internal hose diameter and filter condition. Assessing only the nominal motor power is therefore never sufficient.
Small solids, debris and damp dirt: Vehicle interiors may contain small stones, leaves and fragments that must pass through the nozzle, hose, inlet and separation chamber without causing blockages. Large or sharp metal objects must be removed manually. When the station must also collect water or moisture from wet mats, a purpose-designed wet-and-dry configuration is required to direct fluids towards the bottom of the container while limiting direct contact with the filter cartridge. A wet vacuum cleaner collects free liquids but does not replace a professional extraction cleaner, which applies and recovers a detergent solution for deep cleaning.
Comparison of system architectures: Self-Service Station vs Mobile Unit
Public Self-Service Vacuum Station
Designed for repeated, intensive use throughout the day. It includes timed cycle activation, a coin mechanism or payment system, straightforward customer access and an externally supported flexible hose. The structure is fully protected by stainless-steel panelling to withstand weather conditions, moisture and detergents. Maintenance is simplified through easily removable wheeled drums and filter-cleaning systems accessible to the operator.
Professional Operator-Controlled Vacuum Cleaner
A mobile solution suitable for manual car-wash centres, detailing centres and workshops where the machine is moved directly by personnel. It is appropriate when the operator visually checks the collected material, the hose is moved easily between several vehicles, a coin mechanism or structured timing system is not required, the machine is stored after use and drum emptying is managed internally by the facility.
FEVI configurations dedicated to Self-Service stations
Our self-service vacuum stations can be configured according to the specific operating requirements of the car-wash centre:
- Configuration for dry dirt: Suitable primarily for collecting dust, sand, soil, hair, pet hair and crumbs. It uses a large-surface-area polyester star filter and a gravity-assisted cleaning system. It is the simplest and most straightforward solution where liquid collection is neither expected nor permitted.
- Wet-and-dry configuration with manual cleaning: Suitable where customers may also collect moisture from wet mats, water and small accidental spillages. It is equipped with a 2.2 kW side-channel blower, available with a 230 V or 400 V power supply, an airflow of 320 m³/h, vacuum pressure of 320 mBar, a 13,000 cm² Class M filter cartridge, a 60 mm tangential inlet, a 50-litre wheeled drum and manual filter shaking.
- Wet-and-dry configuration with semi-automatic cleaning: Provides the same performance as the previous version but integrates a semi-automatic system assisted by a pneumo-mechanical piston to promote the release of sand and dust from the cartridge. It is recommended for high-frequency car washes to limit the loss of vacuum performance during the day and simplify filter regeneration for the operator.
Essential construction and technology features
Side-channel blower: The blower, available for 230 V or 400 V supplies, is suitable for frequent and continuous use compared with brushed motors because the absence of carbon brushes eliminates components subject to rapid thermal wear. The unit nevertheless requires periodic inspections, cleaning and verification of cooling airflow and seals. For this reason, the absolute expression “maintenance-free” should be avoided.
Tangential inlet and internal protection: The tangential inlet gives the airflow a rotating movement inside the 460 mm chamber, separating the heavier sand particles through a cyclonic effect and directing them towards the drum. An internal stainless-steel guard installed in front of the cartridge helps limit direct contact between liquids, abrasive materials and the filter media, protecting it from wear. Avoid the absolute statement “the filter always remains dry”.
Time adjustment and removable drum: Electronic timing allows the operator to define the exact service duration according to customer flow, pause times and payment management. The material accumulates inside a removable 50-litre wheeled container, simplifying emptying and cleaning of the surrounding area.
Quick model-selection guide
Public Self-Service Stations
- Single or double outdoor station: Select a dedicated self-service station equipped with a 2.2 kW blower, timer, coin mechanism, external stainless-steel panelling, 50-litre drum and a specific configuration for dry dirt only or wet-and-dry collection with manual or semi-automatic cleaning.
Manual Car Washes and Detailing Centres
- Available 230 V single-phase supply: FEVI WM 375 BASIC;
- Three-phase supply with primarily dry dirt: FEVI BT 753 BASIC;
- Three-phase supply with frequent liquid collection: FEVI WT 753 BASIC;
- Centres with long piping runs or demanding use: FEVI HDC B 155 BASIC for dry materials or FEVI HDC W 155 BASIC for liquids and mixed materials.
Management of multi-station systems: When the car wash must serve several areas simultaneously, the FEVI technical department designs dedicated central vacuum units connected to a shared piping network with centralised separation systems. The simultaneous-use factor of the extraction points is calculated accurately, avoiding the unsuitable or improvised use of mobile units.
Key parameters to verify before configuration
Before defining the configuration, we collect the principal operating variables of the car-wash centre: number of active stations; self-service or operator-controlled use; nature of the dirt, whether dry, damp or liquid; average quantities of road sand; line parameters, including hose length, diameter, number of bends and pressure losses; simultaneous-use factor; electrical supply, whether 230 V or 400 V; daily operating hours; required container capacity; installation location, whether indoors or in a sheltered outdoor area; need for a timer and coin mechanism; and installation side of the hose-support arm.
Materials that must not be collected without prior verification: A conventional car-wash configuration must not be proposed or used to collect fuels, solvents, volatile flammable liquids, corrosive acidic substances, incandescent residues, large quantities of accumulated dense sludge or unidentified chemicals that could compromise the integrity of the filter or hose.

Car Wash Solutions FAQ
Which industrial vacuum cleaner should be selected for a self-service car wash?
Read more
A purpose-designed self-service station equipped with a side-channel blower, electronic cycle timing, coin mechanism, protected external stainless-steel structure, removable wheeled container and an integrated manual or semi-automatic filter-cleaning system is preferable.
Which industrial vacuum cleaner should be selected for a manual car wash or detailing centre?
Approfondisci
Mobile industrial models are preferable for use controlled directly by an operator. FEVI WM 375 BASIC for single-phase applications, FEVI BT 753 BASIC for dry dirt using a three-phase supply or FEVI WT 753 BASIC for alternating solids and liquids can be considered.
What is the technical difference between FEVI BT 753 and WT 753?
Read more
FEVI BT 753 uses a tangential inlet that optimises the cyclonic effect and is specifically designed for dust, sand and dry residues. FEVI WT 753 instead uses a central inlet with an internal deflector, making it the more suitable configuration when liquids and damp dirt are collected frequently.
Can a single-phase industrial vacuum cleaner be used inside a car wash?
Read more
Yes, provided that the operating cycle is not continuous across several shifts and the machine is controlled by an operator. FEVI WM 375 BASIC operates at 230 V, provides 3300 W through three bypass motors and collects dust, solids and liquids inside its 75-litre drum.
When is a three-phase blower preferable or necessary?
Read more
A three-phase blower is recommended when the industrial vacuum cleaner is used frequently throughout the day, remains permanently installed at a fixed station or must overcome substantial pressure losses caused by very long flexible hoses.
Can a car-wash vacuum cleaner collect heavy road sand?
Read more
Yes. Sand can be collected effectively provided that the unit’s operating vacuum pressure, internal hose diameter, inlet configuration and container are correctly sized according to the conveying distance from the nozzle.
Can the machine collect residual water from mats or seats?
Read more
A wet-and-dry configuration, such as FEVI WT 753 or a dedicated self-service station, can collect free water and compatible damp dirt. However, it does not replace a professional extraction cleaner for washing fabrics and removing deep stains.
Is the filter-cleaning system in self-service stations automatic?
Read more
It depends on the selected configuration. Standard versions with manual filter shaking and advanced versions equipped with a semi-automatic system assisted by a pneumo-mechanical piston to facilitate the release of deposits are available.
Does a blower-powered self-service vacuum station require operator maintenance?
Read more
Yes. The absence of brushes in the blower eliminates one critical wear component, but it does not eliminate maintenance. The operator must periodically inspect the filter, empty the drum, check hose integrity, clean the nozzle and verify the unit’s cooling airflow.
What capacity should the residue-collection container have?
Read more
Capacity must be sized according to the average user flow. Dedicated outdoor self-service stations use an internal 50-litre container, while compatible FEVI mobile industrial models provide larger capacities of 75 or 100 litres.
Can one industrial vacuum cleaner serve two separate vacuum stations?
Read more
Yes, but only after a rigorous technical assessment of airflow, vacuum pressure, line length and simultaneous use. In most workshop applications, one machine per station or a correctly sized central vacuum unit is preferable to avoid a reduction in performance.
Si possono aspirare carburanti, benzine o solventi sversati nel veicolo?
Read more
No. This is strictly prohibited with conventional car-wash configurations. Collecting flammable, volatile or chemically aggressive liquids requires a specific on-site risk assessment and purpose-designed certified machinery.
