COPPUS Marine Venturi

Lightweight, Deck-Mount, Compressed Air Drive Ventilator

Easy to transport, rugged, and maintenance-free shipboard ventilator for degassing or delivering fresh air supply to cargo tanks and other on-board confined spaces.

 

Operating Principle: Compressed air or steam is admitted into the Marine Venturi through a single inlet connection in the housing leading to the mixing chamber. The air or steam jetted from the nozzle creates a “Venturi” action that induces a large volume of surrounding air to enter through the inlet end. The air is then discharged at high velocity through the outlet.
