With outdoor air carrying 200 to 1,500 bacteria per cubic metre, an air-conditioning system with a capacity of 10,000 m3/h can potentially take in 2 to 15 million bacteria each hour and seriously contaminate food & beverage production. Efficient air filtration is the solution.

Food safety compliance is our concern

Growing market requirements and increasingly stringent legislation are placing even greater emphasis on hygiene in the food industry. Similarly, the air quality in the production process has never been more important than it is today. Only efficient filters and air recirculation systems can reduce the levels of microorganisms in the air.

Camfil complies with the following industry product standards:

• Fighting against microbiological contamination

• Compliance with VDI 6022 and ISO 846: inert raw materials against microbial growth

• Food certification for components that come into contact with the product

• Compliance with Regulation (EC) No 1935/2004 for all products related to the food industry

• Products which meet HACCP risk requirements (hazard analysis and critical control points)

• Filter, labelling, identification and traceability

• Guaranteed filtration efficiency level in accordance with EN 779:2012 guaranteed filtration efficiency

 Food processing industry

Factors which affect Human Health:

Microscopic causes…

Outdoor air carries 200 to 1,500 bacteria per m3. So an air handling unit with a capacity of 10,000 m3/h will supply between 2 to 15 millions bacteria each hour!

• fungal spores: 1 to 10 μm

• bacteria: 0.2 to 10 μm

• viruses: 1/100 to 1/1000 of micron

• visible range: Hair 100 μm and pollen 10 μm

Catastrophic effect…

• production loss

• withdrawals from sale, return and destruction

• production breakdowns, plant closures

• extra expenditure on controls and remedial actions

• drop in sales

• brand image and reputation damage

• loss of consumer confidence

Food hygiene and safety…

Protecting human health is a major concern for governments of the European Community (Directive 89/397/EEC of 14 June 1989).  Such measures may include product withdrawal and destruction, or even closure of all or part of the offending company for an appropriate period. In order to ensure product safety, those in charge of plants are required to:

• identify every aspects of their business that impact food safety;

• ensure that appropriate safety procedures are implemented, followed and updated, on the basis of ADPCM/HACCP principles.

Air filtration solutions designed for the food processing industry

In both design and construction, Camfil integrates specific characteristics for the food processing industry:

Limiting microbiological contamination

• cleanability

• decontaminability

• moisture control

Resistance to corrosion

• use of stainless-steel materials, plastics, polyester resin…

• consistent solution with HACCP (Hazard Analysis Critical Control Point) risk level

• traceability, identification and labelling of filters

• guaranteed efficiency in accordance with current standards

Rapid development of processes and production

• modularity, flexibility and progressive nature of filtration solutions

• easy and safe to use

Quick and efficient maintenance

• accessibility

• simple installation of filters

• easy to handle

Access for in-situ testing

Access for in-situ testing is tailor-made on request.  Our range of products, dedicated to the Food Industry, are developed in accordance to these requirements.

Food safety compliance certificates

For some components close to the process, Camfil is able to provide food contact certification documents where applicable.

Prosafe range – taking care of your process safety

High-end industries have high-end demands to ensure their Productivity and Process Safety. Food and Beverage or Life-Science activities have set new standards in product quality and therefore require specific characteristics regarding process definition.

Camfil, as the leader in clean air solutions and air filtration, has developed the complete ProSafe range of products designed for the most demanding processes, including safety, traceability and audit requirements.  For air conditioning applications and filtration preparation of your clean rooms, make the choice of the complete ProSafe range, especially designed for Process Safety, with food contact certificates for the materials used (according EC1935-2004) and anti-microbial growth certificates (according ISO846 and VDI6022).

The ProSafe range combines superior efficiency and energy savings with maintenance requirements (as transport through clean room) and easy access to information.

Molecular filtration – challenges and opportunities

Post written by Dr Chris Ecob, Global Business Manager for Molecular Filtration, Camfil Group:

Molecular filtration

The leading organisation responsible for cataloguing chemicals – the CAS Registry (Chemical Abstract Service) – has more than 73 million unique chemicals in their database and is adding new items at the rate of 15,000 every day. Many of these chemicals never pre-existed in nature and have been created by man in the industrial era. Some chemicals only exist as gases in the air.

However, all chemicals, including those that are normally liquids or solids, have to varying degrees the ability to evaporate and become airborne in their molecular form. It is an inescapable fact therefore that all around the globe, there are more chemicals in the air than ever before.

Categorising molecules by impact

Airborne molecules may be categorised according to their impact on humans and our world. Responsibility for smell or odour is perhaps the most obvious.

The receptor cells in the nose and the human brain are capable of detecting and characterising many different odour types. Some molecules are classified as irritants. In addition to creating an odour response, they stimulate an involuntary and negative reaction from the body. The classic example is activation of the tear ducts when chopping onions.

WHO’s classification of outdoor air pollution as carcinogenic calls for more effective filtration in building ventilation systems

The International Agency for Research on Cancer (IARC) – a specialised agency of the World Health Organization (WHO) – has announced there is convincing evidence that exposure to outdoor air pollution causes lung cancer.

Exhaust pipeIARC has also classified a major component of outdoor air pollution – particulate matter (PM) – as carcinogenic. Although both the composition and levels of air pollution can vary dramatically from one location to the next, the cancer agency says that its conclusions apply to all regions of the world.

In a statement, Magnus Yngen, President and CEO of the Camfil Group, made the following comment about IARC’s conclusion:

“It is now officially recognized that outdoor air pollution contains cancer-causing substances, which sends a clear signal to policymakers around the world to improve the quality of the air we breathe in cities where severe air pollution impacts human health and life negatively. However, improving indoor air quality is just as important. To protect occupants in polluted cities, a three-pronged strategy is needed for urban buildings: effective particle and molecular gas filters in air handling units, elimination or control of indoor pollution and, when necessary, supplementary air cleaning with standalone filtration units to deal with special air-quality problems at the source. Without a comprehensive filtration approach, unclean outdoor air supplied through ventilation systems can mix with indoor sources and become up to 50 times more polluted.”   Continue reading
