Marine Air Flow is an Australian company that specialises in engine room ventilation equipment for vessels of all sizes and operating conditions. Ensuring your engine room equipment is free from salt mist and spray is just the starting point of a better engine room ventilation solution for your boat. Having the correct ventilation setup will ensure better operating costs, conditions and an extended lifespan of your equipment. Starting with our custom designed air intake grilles, we can build you an entire system including engine room fans, air dampers, directional air diverters & our Air-On-Demand control system. Each engine room is different so to stand behind the product we sell, all our systems are custom designed based around a short but in-depth questionnaire about your vessel. Our moisture eliminating intake grilles have been in a wide range of vessels for over 14 years with no returns.
