Lightweight, Deck-Mount, Compressed Air Drive Ventilator
Easy to transport, rugged and maintenance free ship-board 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 from the nozzle creates a Venturi action which induces a large volume of surrounding air to enter through the inlet end. The air is then forced out through the outlet at a high velocity.
