Rotolok’s USDA Dairy Accepted line of Rotary Airlocks are designed for use in sanitary applications in the food, dairy, pharmaceutical and chemical industries where regular cleaning is required to prevent product contamination.The product contact surfaces of the airlock are manufactured in 316 Stainless Steel and polished to a 150 grit finish, ensuring that there are no lodgement points allowing the product to flow smoothly.

Furthermore, the airlock is equipped with a slide rail mechanism allowing for the quick and easy removal of the rotor from the airlock body. This addition substantially reduces the amount of downtime and man hours required for the cleaning and maintenance of the rotor and airlock internals.

Our USDA certified Rotary Airlocks are available in sizes ranging from 6” up to 16”.
