ABOUT MARINE AIR FLOW

The Engine Room Ventilation Specialists

Marine Air Flow International is an Australian owned private company which manufactures specialised engine room ventilation products for the marine industry. Our factory is based in Miami, on the spectacular Gold Coast of Queensland, Australia. 

Our business started with our signature product, our Air Intake Separator Grilles, often referred to as "mist eliminator grilles". We started small with just Brad in our farm shed on our personal property in East Trinity in Cairns. After just 6 months we added a second fabricator to our team, a third a short time later, and when we moved to the Gold Coast in 2007, they both came with us.

We purchased our current property in Miami on the Gold Coast in 2014 and haven't looked back. We now have a team of 20, over 30 products in our range and manufacture for a wide cross section of the marine industry such as:

• private owners,
• commercial fishing and tender companies,
• luxury yachts and white boats,
• ocean farming and energy companies,
• & boat builders such as Dongara Marine, Penguin Singapore, Birdon Marine, Norman R Wright & Sons, Fine Entry & Southerly Designs

MAFI's engine room equipment is also in every Riviera vessel over 38m. We are very proud of that one!

The Marine Air Flow Story

Marine Air Flow's owners have been involved in the marine industry for over 30 years.

Initially involved in the boat building industry in Western Australia, Brad Marsden (our Director) moved to Queensland in 1994. Based in Cairns he then took on the role of workshop manager for a local company that built semi submersibles for international export, and aluminium vessels for the tourism industry. 

After 2½ years with this company, Brad was invited to project manage a large architectural glazing project in Singapore. This gave him the chance to combine two of his favoured mediums, glass and stainless steel.

Upon completion of this project, Brad returned to Cairns and with his wife Jenny, started a local business that was responsible for specialist refit services for the marine industry. While it was a very successful business, any refit or repair business can be very stressful and often involves 6 or 7 days a week routinely.

After selling that business in 2004, at Jenny's insistence, Brad went fishing for a year. Literally! Every Monday night Brad and his mate Rod would head down to Kurrimine Beach (south of Cairns) for 2½ days of fishing and golf. It was during this time that Brad started to think about what he might do next.

Always knowing he would stay in the marine industry, Brad wanted his focus to be a business style that avoided the time constraints and stress that doing marine refits gives you. Having had to develop their own ventilation equipment for refit clients through 1990-2004 gave Brad a unique insight into what could be an emerging marine market.

After a decent amount of research it became clear that there was a market for Australian made, affordable, long lasting engine room grilles, air dampers (fire flaps) and fans, and Marine Air Flow was born.
