Worm gear reducers for aggressive environments and high hygiene requirements



CLEAN DUTY is a solution developed by Motovario for the food industry and for all fields of application that require very high standards of hygiene. Clean Duty is made of AISI stainless steel and has been properly treated to prevent water and dirt from stagnating and depositing.

Clean Duty is a gearmotor ideally suited to the primary processing stage, for example on the packaging lines for fruit and other fresh foods.  Its compact size and high-quality surface treatments ensure high resistance, especially in corrosive environments.
