We are planning to set up a new Compressed Air Generation and Distribution System. Is there any specific requirement or guidance on the material of construction of the compressed air receiver (holding tank) and the respective distribution piping? We were wandering whether we can use a material different than SS.
The air compressor will be oil-free, followed by an air-drier. A pre-filter will be positioned at the beginning of the distribution system, just after the air receiver. 0.22μm filters will be positioned before each use point, where the air will come in contact with the primary packaging materials or the product. One of the use points will be in Grade A (ISO 5-Class 100) area and the air will come in direct contact with the product. All the piping inside the sterile areas will be 316SS.
