During the manufacturing process, products emit gases and vapours. For example, nitrogen gas is often emitted after processing to eliminate oxygen, moisture, and humidity. The Filtered Outlet Out Gassing (FOOG) Vent can prevent overpressure caused by these gases. Many products will evolve gasses and vapours due to manufacturing and processing. The integral non-return valve is often used to allow the exit of gas while preventing its entry into bulk containers or vessels to minimise the risk of contamination in products. However, temperature changes will affect the pressure. With the FOOG, it will help to equalise atmospheric variations.
The FOOG Vent features a sintered plastic filter to guard against the fine powder, protecting the non-return valve from effective operations. This filter is made to withstand side loads and shocks that occur during filling and transportation. It is typically used to protect storage bags containing FOOG Vents can be directly mounted into gas tap flanges or bulkhead mounted with an adaptor, typically used to protect storage bags with milk powder and food aggregates. All FOOG Vents are fully automated and require no additional maintenance. They are manufactured under FDA-approved and certified materials for use and contact with food products and can be sterilised for reuse.
