Atlas Copco's stainless steel motors enlarge the field of applications to areas where the environment is corrosive.
This can be in the food processing industries where corroding detergents are used or in the chemical industry where the atmosphere as such is corrosive.
Stainless steel motors are also ideal in explosive environments, the reasons for this are that air motors don't generate electrical sparks and stainless steel reduces the risk of mechanical sparks.
Atlas Copco's stainless steel motors have a clean design with no dirt collecting corners or cavities. The motors are equipped with double seals in flour rubber at the shaft end to prevent water or cleaning detergents from entering the gears. The planetary gear is greased with food grade grease approved according to USDAH1. Atlas Copco's range of stainless steel motors is available in lubricated and lubrication free versions.
The material used in the back head, casing and front part is stainless steel with the designation:
- ISO 683/XII Type 17, SS 142346,
