Agri AirClean - Air cleaner to dairy- and pigbarns.

 billed Agri AirClean

Profitable livestock production with Agri AirClean

At AGRIFARM we have developed Agri AirCleaner as our idea of efficient air cleaning with low power consumption. The cleaning process can be stopped and started up again with full power, and therefore particularly suitable for everything in/out on pig production

Air cleaner developed to local extraction in pigsties and cowsheds

The air cleaner, Agri AirClean, is developed to clean exhaust air from pigsties and cowsheds, and is modulop-built so that it can be adapted to the individual unit. Agri AirClean is specially developed to cope with the additional concentrated air from stables with local exhaust.

Air cleaning principle

Air cleaning with Agri AirClean happens with acid and base, and atmospheric oxidation. Agri AirClean effectively removes ammonia and odor emission from all housing types and all types of livestock.

Process Steps



Less energy consumption

Agri AirClean is designed with a small pressure loss in the interests of minimizing energy consumption and minimizing the cost of air cleaning


Larger livestock production and better bottom line with Air Cleaning

Agri AirClean has a high cleaning efficiency, and supports efficient and economically sustainable livestock. By reducing environmental impact by air cleaning with Agri AirClean, it is possible to increase the production capacity by more animals. When you collect more animals on fewer farms, increased efficiency and thus you can fit more animals with fewer employees. It benefits your bottom line.


Environmental Protection Agency - Advisory Opinion

Agri AirClean approved to clean with following removal rates:

• Ammonia 98%

• Odor 88%


You produce your own nitrogen fertilizer

Sulfuric acid binds most of the ammonia from the exhaust air and to form ammonium sulfate which separates with Agri AirClean. Ammonium sulfate (N fertilizer) enriches your manure with the "free" fertilizer.





Smart Farm management of Agri AirClean

AGRIFARM has developed Smart Farm management for all Agrifarm's housing types to cows and pigs, therefore it is natural to integrate the management of Agri AirClean in Smart Farm.

Your everyday work in the pig barn will be more comfortable with our patented, innovative ventilation system. Besides reduced nuisances from dust, you will also experience less noise since no ventilators are placed in the barn section, they are instead placed in the central corridor.

We have developed the innovative air exchange system with the purpose of creating an optimal indoor climate in your pig barn.

The function of ventilation and heat

The ventilation system is an integrated part of the housing system. All ventilators and ventilation dampers are placed in the central air corridor and can thereby easily be serviced and maintained. If air cleaning is required the air cleaning unit can be integrated into the building without any larger constructional changes.

The inlet of air is below floor level through the façade of the barn where the air is sucked through a heating unit which heats the air. The heat unit is the barn’s heating system and at the same time the heated air prevents down draught of cold air. The air is sucked into the barn through air shafts, is then distributed in the barn sections and thereafter it is sucked out again through air channels below the solid floor. The exhaust air is collected in a central air corridor, where all the ventilators are placed. Ventilation dampers, which regulate the ventilation level in the individual barn sections, are also placed in the central air corridor. 

With the system you get:

  • Improved air change in the barn with reduced energy consumption
  • Improved animal welfare
  • Good indoor housing climate all year round
  • Less and easier maintenance
  • A future - oriented ventilation system which is prepared for air cleaning

With Agrifarm’s patented air exchange technology you have the opportunity to increase your production while at the same time improving environment, animal welfare and your earnings.

With the development of the air exchange technology called Environment Defender we received the EU Environmental Award on March 23rd 2012. Furthermore the technology was launched as a three star novelty at the agricultural fair Agromek in 2009, where we also received the Agromek Award for our technology.

New cutting - edge environmental technology

We have developed and patented a completely new and cutting – edge environmental technology, Environment Defender, and in this system a controlled air stream is flowing across the manure in the slurry channels, thereby capturing ammonia emissions, odor gasses such as CO2, methane and laughing gas/nitrous oxide. The result is less strain on the animals and the immediate environment compared to traditional housing systems.

With Environment Defender up to 90% of the ammonia and 50% of the odor compounds are collected. This means that the air quality in the stable is markedly better than in normal housing systems, and this is achieved without otherwise interfering with the natural ventilation in the housing system.  

With the system you get:

  • Reduced emissions of both ammonia and odor compounds
  • Reduced negative impact of the animals and the immediate environment
  • A good housing climate all year round
  • Improved udder and claw health
  • Improved animal welfare

This is how it works

With the air exchange system a controlled air stream is flowing above the manure across the slurry channels. The air stream captures the majority of the gaseous ammonia and odor compounds, which would otherwise have evaporated into the immediate environment and thereafter into the outside environment. The system can be retrofitted to any air cleaning system. The technology is suitable if you want to deliver your slurry to a biogas plant.
