Formax FD430 Envelope Sealer


The Formax FD 430 Envelope Sealer closes and seals envelopes in a single pass. Simply place a stack of envelopes in the infeed tray, choose a processing speed with the adjustable control knob and in seconds, envelopes are sealed and ready for the mail.

Standard features include an adjustable envelope separator to ensure accurate feeding, a large outfeed tray, heavy-duty metal construction and a precision moistening roller.
