The FOOG vent is designed to withstand side loads and shocks during filling and transit using a sintered plastic filter to guard against releasing fine powder. The vent can be directly mounted into gas tap flanges or bulkhead mounted with an adaptor flange to protect packagings, such as storage bags containing milk powder and food aggregates. FOOG Vents are Food and Drug Administration (FDA) approved and manufactured from certified materials for use and contact with food products and can be sterilised for re-use.
The Filtered outlet outgassing (FOOG) vent prevents over-pressurisation by releasing air during and after manufacturing processing. During the manufacturing process, products evolve from gases and vapours. For example, nitrogen gas is often emitted after processing if used for blanketing purposes to eliminate moisture and humidity and inhibit oxygen. The vent can prevent overpressure caused by the gassing of a product during and after processing.
Temperature changes can affect the pressure, and the integral non-return valve permits gas to leave the bulk container or vessel. The vent prevents gas from entering, minimising the risk of product contamination by equalising atmospheric variations.
- Prevents over pressurisation and helps to out-gas a product during and after processing
- Applicable bulk bags, any flexible storage and products that release gas while in an air-tight environment
- Low cost and effective solution
