CentorMail MAX excels at swiftly and reliably processing high volumes of mixed mail formats without breaking stride. Its nearly one-inch pass-through is the widest in the industry, which means it can even handle fat, 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. And if you add the available inline automatic dynamic weighing option, you can load mail without presorting and let CentorMail run postage automatically with the speed and efficiency it’s renowned for.
