How does MAP (Modified Atmosphere Packaging) help you with keeping you food fresh?
May 5, 2021
But it's not enough to get nitrogen into the package—the gas must be food-grade compliant. It must be free of contaminants such as dust, oil, water, gases, and micro-organisms. This is not just necessary for a high-quality product, it's necessary for the protection of customer health and for preserving the credibility and reputation of your business and brand. Food air safety is paramount. In fact, the ISO (International Organization for Standardization), SQF (Safe Quality Food Institute), and BRC (British Retail Consortium) have identified compressed air used in packaging and processing as a possible threat to food air safety.
So how exactly do these contaminants find their way in?
In the case of oil-lubricated compressors, they would be present in ‘carried over’ oil.
There's water vapour that builds in the compressor as a result of condensation, and let's not forget contaminants in the form of rust and scaling that builds up in the piping.
These contaminants are screened out methodically with the help of filters and dryers including:
- Coalescing filters: removes wet particulate and oil aerosols
- Adsorption filters: removes oil vapour
- Dust removal filters: removes dry particulates
- Sterile filters: removes micro-organisms and solid particulates
- Adsorption dryers: removes water vapour
In this new era that calls for heightened standards of hygiene and safety, are you equipped to make sure your food products meet the mark? Are you covered when it comes to food air safety?
Pneumatech filters have been fully tested and qualified according to the latest ISO8573 and ISO12500 standards. To know how you can protect your investment in equipment and processes, browse Pneumatech's enhanced filtration systems and replacement elements.

How do I know which type of air dryer i need for my compressor?
Air dryers are used downstream of an air compressor to rid the compressed air of any moisture or humidity before it reaches your application or final product. Using air dryers is imperative in many applications such as the food/beverage industry, electronics manufacturing and spray painting in the automotive industry.
