ARTURO cabinet air purifier for commercial kitchens, 3,400 to 27,200 m³/h

It is a complete system for the air extracted by commercial kitchen hoods: in a single cabinet, G4 prefilter, F9 rigid bag filter, 1 to 3 stages of electrostatic cells, activated carbon cartridges and fan. It is supplied with the ozone generator sized to the required airflow and with the inverter control panel that runs the whole system. ETC Group patent no. 102022000000572.

Restaurants, pizzerias, rotisseries, fish and chip shops, delicatessens, canteens and food production units: commercial kitchens with an extraction hood.

The cabinet series has a frame in P40 aluminium profiles and sandwich panels, in 9 sizes from 3,400 to 27,200 m³/h. ARTURO 30 INOX and ARTURO 60 INOX are the enclosed stainless steel versions.

From the BFMT activated carbon unit of the same size: the electrostatic section fits into the same cabinet and keeps its width and height. Only the length changes.

The G4 retains coarse particles, the F9 fine particulate and grease droplets, the electrostatic cells smoke and grease particles, the activated carbon odour molecules and residual ozone.

It handles air that has already been cleaned, so the impeller does not get coated with grease and maintains its performance over time.

No. It works downstream of the hood grease filters, and the hood must be sized separately. Without grease filters, grease clogs the prefilters within a few days and reaches the carbon.

No. The machine treats the air, while checking local regulations and permits is the responsibility of the designer and the business owner.

Not on its own: a stage for removing sparks, embers, soot and heat is needed first. The activated carbon works with air up to 40 °C.

Explosive atmospheres, flammable gases or dusts, air above 40 °C or 70% relative humidity, operation without prefilters, with cells missing or with access doors open, ozone generator on with extraction stopped, washing with water jets.

Nine: ARTURO 30, 45, 60, 75, 90, 120, 150, 180 and 240, with maximum airflows from 3,400 to 27,200 m³/h.

The maximum airflow in hundreds of m³/h, rounded: ARTURO 60 handles up to 6,800 m³/h, ARTURO 120 up to 13,600 m³/h.

Add up the airflow of the connected hoods and choose the size with a maximum airflow equal to or greater than that. The operating airflow is then set with the inverter.

No. Each size is made up of full 610 × 610 mm modules or half 305 × 610 mm modules: for an intermediate airflow, choose the next size up and adjust it with the inverter.

Yes, up to 50,000 m³/h, with custom-engineered configurations developed by ETC Group S.r.l.

It is the static pressure the fan leaves available for hood and ducts, with clean filters and at maximum airflow: 400 Pa on all sizes, 600 Pa on ARTURO 150.

About 450 Pa with clean filters and cartridges, a value that increases as they get dirty. Each electrostatic stage adds about 80 Pa.

Approximately from 220 × 73 × 73 cm for ARTURO 30 to 380 × 254 × 160 cm for ARTURO 240 (length × width × height); each additional electrostatic stage adds a section. These are hypothetical dimensions, not to be used as a design basis: actual drawings are only available once the machine has been built and on explicit request.

From 280-320 kg for ARTURO 30 to 1,900-2,400 kg for ARTURO 240, without carbon. The carbon ranges from 48 to 384 kg depending on the size. These are indicative weights; the exact weight of the supply is on the delivery note.

Looking at the machine from the access door side, in the Sx version the air exits on the left, in the Dx version on the right. It is chosen when ordering. Large sizes can be supplied in several modules to be joined on site.

One, two or three in series, chosen when ordering and stated in the order confirmation. Each stage is a bank of cells covering the whole cross-section.

With 1 stage 90% on smoke, grease and particulate and 70% on odours; with 2 stages 95% and 85%; with 3 stages the efficiency rises further and the values are given in the documentation of the individual supply. Data for the electrostatic section only, at nominal airflow, with clean cells.

ETC Group recommends starting with two stages. The final number is decided at design stage based on the type of cooking, the amount of smoke and grease and the discharge conditions.

It is a two-stage design: in the ionisation zone the electrodes charge the smoke and grease particles, in the collection zone the collector plates retain them until washing.

ESC 6060, 60 × 60 × 30 cm, up to 3,400 m³/h each, and ESC 3060, 30 × 60 × 30 cm, up to 1,700 m³/h. Sizes 45, 75 and 150 also use the half cell.

The electrostatic stages of ARTURO use the same ESC cells as the NEXION filters. 1, 2 and 3 stages correspond to the NEXION, NEXION X and NEXION XX configurations: air passes through them in series and each stage treats again the air already treated by the previous one. The cells operate at a face velocity of about 2.7 m/s at maximum airflow.

Aluminium frame and plates, ceramic insulators, stainless steel pins and springs. They slide out from the front on rails, without tools.

Each stage has its own ESC HV power supply, mounted inside the panel door: input 230 V single-phase 50 Hz, output 8-12 kV DC.

Typically every 3-4 weeks, every 2 weeks with grills and fryers, with a visual inspection every 2 weeks. The correct frequency is set on each system.

In warm water at 40-50 °C with a 1-2% neutral degreaser for 15-20 minutes, in a dishwasher or with ETC SONIWASH ultrasonic washers. Then rinse and dry completely: a damp cell causes arcing.

Caustic soda, strong alkaline detergents, concentrated acids and pressure washers: they corrode the aluminium, damage the insulators and deform plates and rails.

No, it must be replaced. Bending electrodes or plates changes the distances between live parts and can cause arcing and short circuits.

G4 ISO Coarse 55% prefilter (592 × 592 × 48 mm) and F9 rigid bag filter ePM1 85% (592 × 592 × 292 mm), with half sizes on sizes 45, 75 and 150.

The G4 every 15-30 days, the F9 every 30-60 days, or in any case when the pressure drop reaches 250 Pa.

No, they are consumables. On request the G4 can be replaced with a metal G2 prefilter, washable in hot water with neutral degreaser.

CCA140 cartridges, Ø 140/70 × 400 mm with bayonet fitting, each containing about 3 kg of virgin granular carbon of mineral origin, mounted on plates of 16 or 8.

From 16 cartridges and 48 kg of carbon on ARTURO 30 to 128 cartridges and 384 kg on ARTURO 240.

In a kitchen with normal service it is replaced every 6-12 months; with grills and very intensive cooking, as often as every 2 months. The first sign is odour returning at the outlet.

Yes, with loose carbon of the same type and in the same quantity. ETC Group supplies it in 25 kg bags (code SCA25KG).

Air up to 40 °C and 70% relative humidity. They must not get wet: damp carbon loses adsorption capacity.

Sealed in bags without shaking them, away from heat sources and never stored in enclosed rooms. The EWC waste code is assigned based on the substances retained during operation.

Yes: flat panel filters with activated carbon, alumina or zeolite. The airflow and the pollutant to be treated must be specified when ordering.

Yes. Every ARTURO comes with the ETC ozone generator sized to the airflow required by the system, controlled by the ARTURO panel. The generator has its own CE marking, manual (ETC-MAN-O3-2026) and declaration of conformity.

Ozone injected into the hood oxidises part of the odorous substances before the machine and reduces the load on the activated carbon. The carbon downstream retains the residual ozone.

It draws in room air through a filter, passes it between high-voltage emitters and sends the ozone into the hood, where it oxidises volatile grease and odour molecules.

On the required airflow: the starting dosage is 10 g/h per 1,000 m³/h of treated air, then it is adjusted to the type of cooking, the workload and the available contact time.

Starting examples: ARTURO 30 COMPACT Com.40, 45 Com.60, 60 Com.80, 75 CUBIK O3-100, 90 O3-120, 120 O3-120 + Com.20, 150 O3-180, 180 O3-180 + Com.40, 240 O3-180 + O3-100.

Into the hood or immediately downstream of the fume source, always upstream of the activated carbon, with at least 3 seconds of contact time before the air purifier. The carbon retains the residual ozone.

In Greenlab reports 2877/19 and 0995/25, ozone at the outlet was below 0.05 mg/Nm³, on systems with 1 electrostatic stage and a 40 g/h generator.

CUBIK has a hexagonal body with six housings for the emitters (models from O3-30 to O3-180); COMPACT is smaller (models from Com.10 to Com.120).

Indoors only, between 0 and 40 °C and with relative humidity between 35 and 70% non-condensing, at least 30 cm from flammable materials, with the sign indicating that the generator is in operation.

No. It is not used to sanitise rooms, surfaces or food, and ozone must not be released into spaces occupied by people or animals.

Up to ARTURO 120, a double-inlet centrifugal fan with forward-curved blades, belt-driven with V-belts and a belt-tensioning slide rail. From ARTURO 150, TLZ direct-drive fans, without belts.

Yes, as standard on all sizes. A single control panel with Toshiba VF-S15 inverter controls the whole system: fan, electrostatic cells and ozone generator, with the safety interlocks. Wiring diagram ETC0002024.

It soft-starts the fan, reduces stress on belts and bearings, sets the airflow to the design value and protects the motor from thermal overload.

Maximum frequency 50 Hz, recommended minimum 30 Hz, acceleration and deceleration ramps of at least 14 seconds, motor rated current as per rating plate.

9/9: 2,100 rpm; 12/12: 1,600; 15/15: 1,300; 18/18: 1,100. For TLZ fans the rating plate data apply. The limits also apply with the inverter.

No greasing: they are sealed, lubricated for life, with a minimum theoretical life of 30,000 hours. The impeller is balanced to VDI 2060, grade Q 6.3.

The panels provide 40 dB of sound insulation; the configuration tested by IMQ measured 70 dB. At the installation site noise is measured during acceptance testing; attenuators with splitters reduce it by 15-20 dB(A).

The installer and the client, in accordance with D.P.C.M. 14/11/1997 and the municipal acoustic zoning plan. It is advisable to assess them at design stage.

Companies or persons meeting the requirements set by law. ETC Group supplies the machine; positioning, brackets, ducts and connections are the installer's responsibility, unless otherwise agreed in writing. On request ETC Group assesses installation with a dedicated quotation.

In a covered room or enclosure, with ambient temperature from -20 to +45 °C, away from heat, steam and flammable substances. Outdoors, the cover listed among the accessories is required.

At least 750 mm in front of the electrostatic section and 600 mm in front of the other sections, plus 150 mm from the walls at the high-voltage power supplies.

Supported under the base frame with sections or brackets, with supports sized for the weight including carbon plus 50% (minimum 200 kg), level within ±2° and with anti-vibration mounts.

Mechanical anchors on solid concrete, chemical anchors on hollow brick, bolts at least M8 in stainless or galvanised steel with self-locking nuts. The calculation is the responsibility of the designer or structural engineer.

On a flat base or on the adjustable feet supplied as an option, properly levelled; on lightweight floors, with anti-vibration mats or mounts.

It distributes the air over the whole cross-section. With the duct connected directly to the panel, air passes through only part of the filters, cells and cartridges, which clog and saturate sooner.

With flexible connectors on inlet and outlet, straight runs of at least 2.5 diameters before and after the machine, 45° or 30° bends after the fan and velocity not exceeding 12 m/s.

By sealing all flanges with butyl tape or neutral-cure silicone: every leak is an air path that bypasses the filters.

Only with safety guards with a mesh no larger than 12 mm, in accordance with UNI EN ISO 13857. Otherwise they must be connected to ducts at least 900 mm long.

Where cooking produces a lot of steam and grease aerosols: it is mounted on the duct between hood and air purifier, with a drip tray, drain and trap.

To a dedicated trap with a minimum fall of 2%, never to a pressurised pipe, filling the trap before start-up.

With a forklift or slings and a spreader bar under the base frame. The centre of gravity is offset towards the fan. Never lift it by the openings, panels, handles or motor.

Number of packages, condition, model, number of stages, Sx or Dx version and serial number. Damage must be recorded as a specific reservation on the carrier's document and reported within 24 hours. Delivery terms are EXW Tavullia (Incoterms 2020).

In a covered, dry room, from -10 to +45 °C, with cartridges and filters in their sealed packaging away from solvents and paints. If stored for more than 3 months, turn the impeller by hand every month.

At 400 V three-phase 50 Hz via the inverter. Alternatively, depending on the version ordered, with 230 V single-phase input, single-phase inverter and motor connected in delta.

With a dedicated 230 V single-phase 50 Hz line, protected by a 30 mA type A RCD and an MCB sized on the number of power supplies.

At 220-240 V single-phase 50 Hz, on a line with dedicated RCD and MCB and earth resistance not exceeding 10 ohm.

D.M. 37/2008, CEI 64-8 and CEI EN 60204-1, following wiring diagram ETC0002024, by qualified personnel. The earth conductor is connected first.

Cells and ozone are enabled only with the fan running and switch off immediately if it stops; at normal shutdown the ozone switches off first and the fan keeps running for purging; no unintended automatic restart when mains power returns.

The cells remain charged even with the machine switched off, and the inverter capacitors for at least 5 minutes. After the wait the cells are discharged to earth with an insulated tool.

The installer, once the system is complete, filling in the commissioning record attached to the manual.

With a 3-5 second pulse with the access doors closed. If the impeller turns the wrong way, reverse the inverter direction parameter or swap two phases downstream of the inverter.

Green LED: cells operating. Red LED: alarm for prolonged arcing or fault. Crackling below 5 per minute: wash within a week; above 10 per minute: wash immediately.

Switch on extraction from the panel before cooking; cells and ozone start with the fan. During operation access doors and panel doors remain closed. At shutdown the ozone stops first and the fan completes the purge.

After the first 8-24 hours, then every 3 months. The complete set is replaced every 15,000 hours or earlier if worn. Tension is measured with the deflection method: f = T × 1.5 / 100.

Every 6 months pulleys, bearings, ozone generator and interlock test; every 12 months overhaul of insulators, electrodes and power supplies, cleaning of impeller and cabinet, electrical tests on the control panel.

The hood grease filters every week; the ducts by a specialist company, with a report, 1 to 4 times a year depending on use, with reference to the UNI EN 16282 series.

Check for saturated carbon, missing or unlocked cartridges, badly closed access doors and excessive airflow; then check the ozone dosage.

The most common causes are clogged G4 or F9, dirty cells, loose belts, an obstructed duct or reversed rotation: replace the filters, wash the cells and measure the airflow.

Isolate the machine, close the fire dampers, activate the hood fire suppression system if present, do not use water on grease or live parts, do not open the access doors while the machine is hot, and call 115.
