To meet the most demanding requirements, 3 compression technologies are available for a oil free air production: - BLOCAIR BK oil-free pistons compressors - SPIRALAIR scroll compressors - WISAIR water-injection compressors certified CLASS 0 according to the ISO 8573-1 standard. Many sectors of the industry (pharmaceutical, food, electronic, textile) cannot take the chance of having oil contaminants enter their processes or products. For this reason, when compressed air must be used in one of these sectors, a technology that can exclude any chance of contamination is a requirement. The reference standard for professionals is ISO 8573-1 (2010), in which Class 0 represents the best possible air quality. It is the only way to make sure that the air used in the processes is completely oil free, making it an amazing investment.
