Intercept hoppers are used in combination with industrial vacuum cleaners or with filter hoppers in order to increase the collection capacity. Depending on the application, intercept hoppers can have a conical form, large discharge doors, can be designed as standard transport containers or can have special forms or volumes according to the customer’s requirements. Suction material can be discharge continuously or discontinuously. Frequently, intercept hoppers are required to create an optimum vacuum system which fully complies with the customer’s material handling concept.
