Removes odours quickly
Removing grease, smoke, and steam particles is a challenge for kitchens, but so is removing malodours and smells. Geniox VOClean comes with filters that remove grease and other volatile organic compounds in the air, eliminating odours quickly from the surrounding air.
Easy to clean
Filter systems in kitchen-based AHUs need frequent cleaning and maintenance. This is why you can ask for your Geniox VOClean to come with an autowash system that cleans the precipitators on a pre-set schedule – to help save precious maintenance costs.
Everything is under control
Select the best control option to suit your needs. From three levels of controls; Variable frequency driver which allows the variable speed control, Basic Control which also covers autowash adaptation or Advanced Control which integrates the BMS integration. For more information, check out the brochure!
Suits multiple kitchens
Geniox VOClean Ecology Units come with multiple density types to suit all kinds of kitchens and catering establishments. From light-density units for cafés and tea shops, through to high or heavy-density units for fast food restaurants and steakhouses. The unit can be configured to run continuously up to 120°C.

What are ecology units?
Ecology units are ventilation equipment tailored to kitchen exhaust systems where grease, smoke, and odour particles emitted from cooking can adversely affect human health. They play a vital role in maintaining high indoor air quality in homes, restaurants, hotels, and other hospitality venues.
Left untreated, the accumulation of volatile organic compounds (VOCs) and other particulate matter released in ducts of exhaust equipment leads to increased risk of fire. Also to clogging and contamination of fans and filters, which reduces the lifecycle and efficiency of the equipment.
How does the electrostatic precipitator work?
In an Ecology Unit, the Electrostatic Precipitator (ESP) is the most crucial part of the system, it is the components that trap most of the dust and grease particulates.
)
As air passes into the combined ionizer/collector cell, the particulates in the air stream are polarised to a negative potential. As they continue through the ioniser and between the collector cell plates, the polarised particulates are repelled away from the negatively charged plates and attracted to the earthed plates where they stick. This allows the particulates to be filtered out of the air flow.
The diagram provides a brief visual overview of how an electrostatic precipitator works.
UVV technology
UV technology is used efficiently in kitchen ventilation as well as in many other applications around the world.
)
Ultraviolet rays are divided into three as A-B-C. UVV rays are in the wavelength range of 100-200 nm. As ozone (O3) is produced within this range, optimum wavelength value is accepted as 185 nm.
UV rays with a wavelength of 185 nm, which are frequently used in kitchen applications, allow photolysis and ozonolysis processes. While the bonds between the atoms forming the oil particles are broken by photolysis, the oxygen (O2) atoms in the air are separated in the ozonolysis process and these atoms come together to form ozone (O3). The resulting ozone molecules interact with oil and other organic compounds in the air, helping contain bad odours.
UVV lamps have a lifetime of 9,000-10,000 hours. They must be changed at the end of their lifetime.
Applications by density
When choosing an AHU to support a kitchen, restaurant, or other catering establishment, you need to consider the most common cooking methods that will be used, or types of food that will be prepared in the kitchen.
This is because different cooking methods release different amounts of grease, steam, and other particles into the air, and will affect the Geniox VOClean models you will need for your project. See the chart for examples.
Light Density
Most standard kitchen exhaust fans are suitable for high-temperature operations.
Examples: Cafés, tea shops, sushi shops, dishwashing areas.
Medium Density
Carbon filtration is needed with a contact time of at least 0.2 seconds after the electrostatic filter.
Examples: Pubs, Pizza restaurants, most Italian and French restaurants.
High Density
A two-stage electrostatic filter followed by carbon filtration with a minimum contact time of 0.2 seconds is required.
Examples: Fast Food, Fried Food.
)
Heavy Density
Carbon filtration with a two-stage electrostatic precipitator followed by carbon filtration with a minimum contact time of 0.2 seconds and a UV ozone system or minimum contact period of 0.4 seconds is required..
Examples: Steakhouses, BBQ restaurants.
Cooker Hoods
Cooker hoods play an important role in kitchens and catering establishments. These help balance the air in the kitchen by quickly removing smoke, grease, and other particles from the air above stovetops, deep fryers, and more.
Systemair offers cooker hood applications to support your Geniox VOClean, including:
Exhaust only
Exhaust only, for low ceiling
Exhaust with air jet
Exhaust with air jet and air supply
Air supply plenums

Casing – insulation, thermal bridging, and leakage classes
Geniox VOclean’s casing comes with thermal insulation class T2, thermal bridging class TB2, deflection class D1, air leakage class L1, and filter bypass class F9.
Activated carbon filters
Geniox VOClean comes with activated carbon filters which are placed after the finer filtration grades (electrostatic precipitator, bag and/or HEPA filter) to stop grease and solid particles from blocking the carbon filter so they perform better, for longer.
EPA/HEPA filter
Like the pre and post mesh filters, the EPA/HEPA filter supports the performance of the activated carbon filters.
Electrostatic precipitator
Geniox VOClean comes with two highly efficient electrostatic precipitators (ESPs). One to remove grease, smoke, steam, and odours from the air by ionising the particles, and a second stage ESP for high density grease and particle control.
Pre and post mesh filters
Help trap larger particles to improve the performance of the finer, inner filters.
Bag filter
Provides longer lifespan for the activated carbon filter by filtering particles.
UVV lamps
Ozone-producing, high energy UV-C lights to sterilise the air.
Doors and handles
Geniox VOClean’s doors and handles are strong and seal well to prevent thermal leakage, while providing easy access for cleaning and maintenance.
Plug fan motor
A highly efficient, direct driven plug fan motor with standard IE3 motor efficiency.
