Compressed Air Filtration Standards
It consists of nine parts that address purity classes specifications and procedures.
Compressed air filtration standards. Additionally the article provides an overview of the compressed air purity classes defined by iso 8573 1 2010. Why compressed air filtration is necessary. Iso8573 the compressed air quality standard iso8573 is the group of international standards relating to the quality or purity of compressed air. By installing proper compressed air filtration at the point of use you will meet or exceed gfsi cfr title 21 and the sqf standard for compressed air.
Spx flow s hankison filter is designed to meet iso 8573 1 and iso 12500 standards. In this situation it is recommended a point of use filter is installed. One cubic foot of compressed air can contain millions of dirt particles considerable amounts of water and oil and even heavy metals like lead cadmium and mercury. A very good start iso 8573 1.
The code of practice gives minimum purity quality standards for compressed air and defines allowable levels for dirt water and oil in line with air quality levels. The quality of the compressed air must be monitored periodically to fulfill national and international standards. The standard consists of nine separate parts with part 1 specifying the quality requirements of the compressed air and parts 2 9 specifying the methods of testing for a range of contaminants. When using compressed air to blow out bottles prior to inserting tablets or to run machinery the most stringent air standards is not necessary because of the expense or the difficulty to regularly test the air quality.
Point of use sterile air filtration is critical to ensuring rte food safety at any point where compressed air can contact the food or food contact surfaces. Donaldson has three filter combinations outlined below that meet the sqf air quality standard. Ft 3 min from an air compressor operating at 100 psi will might handle about 30 gallons of condensed water every 8 hours notes the compressed air and gas handbook. Iso 8573 is an available standard addressing compressed air quality.
Air quality standards or legislation specific to the food manufacturing industries. For instance there is a higher standard when air comes into direct contact with the product so to meet the required standards and save costs nex flow has provided a list of some regulatory body quality factors and impacts of contaminants. The iso 8573 air quality standards and iso 12500 compressed air filter standards make the basis for air treatment product selection much easier. Food and packaging industry uses compressed air in so many processes.
At room temperature a filtration system designed to handle air traveling at 500 std. Various standards need to be met based on different applications.
