Product Overview

When your divers are breathing harder and faster, they have the potential to out breathe the system air supply. For this application we have added (2) 3 gallon aluminum accumulator tanks that will fill and storage air while the compressor is running, allowing the divers to breathe harder while not out breathing the system.

The Explorer CTD390X is equipped with Brownie’s™ Dual head direct drive compressor and the ever-reliable HONDA 5.5HP, 4-stroke OHV gasoline engine mounted on a sturdy aluminum frame with rubber isolator feet.
