Strengthening On-Farm Biosecurity with the Munters Reventa AirProTec Fresh Air Filtration System

Maintaining strong biosecurity has become one of the most important priorities for poultry producers across the UK and Ireland. The increased presence of highly pathogenic avian influenza in wild bird populations, combined with changing weather patterns and higher levels of migratory activity, means that farms face more external pressure than ever. The winter seasons outlined in the biosecurity briefing show how quickly AI can move through wild birds, how long the virus can survive in the environment and how easily it can reach poultry units through contaminated surfaces, feed, equipment, people and water.

Producers are already familiar with biosecurity routines such as visitor controls, wheel washes, rodent management, strict clothing rules and careful farm access. These remain essential, but as highlighted in the presentation, biosecurity is only as strong as its weakest link. One of the main uncontrollable risks is the quality of incoming air. Wild bird faeces can carry extremely high viral loads and the virus can stay active for long periods in cold or wet conditions. Many farms are surrounded by high risk zones where wildfowl activity increases the possibility of airborne particles moving toward the sheds. Incoming air that is not filtered leaves an open point of vulnerability, regardless of how strong every other biosecurity measure may be.

Introducing AirProTec as a front-line defence

The Munters Reventa AirProTec Fresh Air Filter Module is designed to close that remaining gap. It provides a controlled and filtered supply of fresh air that reduces the risk of airborne contaminants entering the building. The filtration system uses a multi stage approach which includes a wind protection net, a G4 pre filter and an F9 main filter that removes fine particles that may carry viral material . This ensures that fresh air entering the building is cleaned before reaching the flock.

The system moves incoming air through each filter layer while maintaining positive pressure inside the shed, reducing the likelihood of unfiltered air being drawn into gaps or openings . The controller also monitors differential pressure across the filters and provides alerts when filters are dirty or if a leak in the airflow is detected. This avoids unnoticed breaches and supports consistent biosecurity performance throughout the crop. The wind protection net helps block leaves, dust and coarse material at the inlet, while the dual filtration stages capture fine particles and dust that can carry pathogens.

For larger installations, the AirProTec 10000 and 20000 modules also include an optional evaporative cooling system to support temperature management during warm periods, helping maintain flock comfort without compromising air hygiene .

Why filtration matters for biosecurity

The biosecurity report repeatedly stresses that many risks originate outside the shed and cannot be removed entirely. Wild birds, neighbouring farms, feed deliveries and environmental contamination all sit outside a farmer’s direct control. Filtration gives producers a practical and effective way to limit one of the most unpredictable risk pathways while supporting stronger flock health and reducing the potential economic losses associated with disease outbreaks. Better filtration supports better performance, fewer disruptions and greater confidence during high risk seasons.

A practical system for every farm

AirProTec is designed to fit smoothly into both new and existing poultry houses. The compact module connects directly into the supply air system and delivers high grade filtration without requiring major structural changes. This makes it a practical upgrade for producers who want stronger biosecurity without a complicated installation.

The filtration performance is a key advantage. Independent testing has shown that the system can remove up to 98 percent of airborne viruses and bacteria before air reaches the flock. This level of protection supports healthier birds and provides a strong line of defence during high risk periods.

The filter elements have a long service life and can be replaced quickly which helps reduce downtime and keeps ongoing maintenance simple. The integrated controller monitors differential pressure and alerts the user when filters need attention which supports consistent performance throughout the crop.

Producers with larger sheds can also benefit from the optional cooling function available on the higher capacity units. This cooling stage lowers incoming air temperatures during warm periods while still protecting air hygiene and ensuring a stable shed climate.

AirProTec provides reliable, clean incoming air that supports flock health and daily farm performance. It is a practical and scalable solution for farms of any size that want to strengthen their biosecurity by addressing one of the most challenging risk pathways.
