Compressed Air Quality Standards in Food Industry

This white paper discusses the critical aspects of compressed air quality in the food industry, emphasizing the importance of adhering to strict standards to ensure food safety. It outlines the requirements for compressed air preparation and the various quality classes defined by ISO 8573-1:2010, which specifies permissible contamination levels and particle sizes. The document details the necessity of different compressed air qualities for various applications, such as pilot air and process air, and recommends a combination of centralized and decentralized preparation methods to optimize efficiency and minimize contamination risks. Additionally, it presents filter cascades suitable for different food types, highlighting the specific quality classifications required when compressed air comes into direct contact with food. The paper also references guidelines from organizations like VDMA and BCAS to assist in determining appropriate filter cascades for compliance with industry standards.
