CentorMail MAX can quickly process up to 120-140 letters per minute without breaking a sweat. With the widest pass-through in the industry, it can handle padded envelopes and thick publications. CentorMail is the only machine for businesses that feeds mail vertically — just like the U.S. Postal Service. This allows for the most reliable, jam-free operation, which eliminates any stress and frustration from the process. With its mixed-mail process, you can load mail without having to presort and simply let CentorMail handle the rest. The dynamic scale automatically calculates accurate postage while mail is processing. CentorMail MAX provides you with high-volume ink tanks which allow you to go longer durations between refills and lower ink costs.
