The CTEK 18B Band Mask is a fully tested and certified unit designed for rigorous mixed gas and shallow water commercial diving. It distinguishes itself from the 28B model with its classic hand-laid fiberglass frame (yellow), known for durability and strength.
The mask integrates the high-performance SuperFlow® 350 regulator and the Tri-Valve® exhaust system to ensure low inhalation resistance and a dry interior. With its non-modular communication options and secure BandKeeper® system, the 18B remains a trusted standard for professional divers demanding a traditional fiberglass frame.
