When it comes to maritime operations, one thing is certain: the environment is unforgiving. Saltwater, humidity, and pressure fluctuations create a unique set of challenges — and that’s exactly where Air Defence thrives.

At Air Defence, we design and manufacture engineered ventilation protection systems that help marine systems perform under pressure — literally. Based in Australia, our solutions are proudly built to endure harsh environments while delivering peak performance.

💡 The Problem We Solve

Marine platforms — from naval ships to private vessels — face consistent threats:

• Moisture ingress and salt contamination in ventilation systems
• Internal structural corrosion
• Equipment degradation and reduced service life
• Non-compliant or underperforming ventilation hardware

Our mission is to stop these issues before they start.

Due to the success of the Vent Heads fitted to the void ventilation systems, additional SMS units have now been fitted to various HVAC intakes onboard. These units were designed to be bolted in to prevent the requirement for welding.

Air Defence Launch as standalone brand, branching off from parent company Maritime Professional Solutions. “With the increase in demand for our custom ventilation protection devices, we have decided to create “Air Defence” for the sales, manufacture, and installation of all our products. Air Defence now have their own workshop, tooling, machinery, and workforce within the Rivergate Marina & Shipyard, to better serve and supply our existing and new customers” Daniel Fodie – Director – Air Defence.

The Australian Navy’s newest fleet of vessels are being fitted out with Air Defence ventilation intakes. Each vessel that is built by Austal Ships will receive 5 Vent Heads, 8 x single stage SMS and 6 x 2 stage SMS. While previous patrol boat fleets suffered badly from corrosion, the ECCPB fleet will benefit greatly by having mist eliminators in place from build.
