AFI Air Horns

When navigating crowded waterways or signaling in low-visibility conditions, AFI air horns deliver the powerful, reliable sound output marine operators depend on. Operating under the Marinco brand, AFI has specialized in manufacturing compressor-driven air horns specifically engineered to withstand the harsh marine environment, combining durability with commanding acoustic performance that meets ABYC and NMMA regulatory standards.

FullBlast Series: Maximum Volume and Compliance

AFI's FullBlast compressor-driven air horns represent their flagship line, producing sound levels between 120 and 127 dB and meeting ABYC and NMMA regulations for vessels up to 20 meters (66 feet). Available in both single and dual trumpet configurations, these horns utilize chrome-plated brass construction with non-corrosive Lexan diaphragms that resist degradation from salt spray and UV exposure. The Full Blast series dual trumpet kits include the necessary air compressor, mounting hardware, and connection fittings for straightforward installation on recreational and commercial vessels.

Engineered for Marine Durability

What distinguishes AFI air horns in the marine marketplace is their material selection and construction methodology. With over fifty years of experience designing sound devices for harsh marine environments, AFI uses stainless steel for critical components including trumpets, motor covers, diaphragms, and mounting hardware. Their Mini Trumpet Air Horns feature solid chrome-plated brass construction that is rust and corrosion resistant, able to withstand harsh conditions, making them suitable for continuous saltwater exposure without performance degradation.

Compact and XLP Options

Recognizing that space constraints vary across different vessel types, AFI offers compact series air horns designed for installations where mounting area is limited. For boaters seeking enhanced protection, the XLP trumpet horns feature complete over-molding of the internal motor cover housing, providing added protection backed by a five-year warranty. AFI also makes replacement air compressors available separately, simplifying maintenance and extending the service life of existing installations.

12V and 24V System Compatibility

AFI air horns accommodate standard marine electrical systems with 12-volt and 24-volt configurations. These dual-trumpet air horns use a small 12V DC air compressor to produce a rich, melodic sound that commands attention, with fundamental frequencies typically ranging from 315 to 375 Hz. The two-tone design creates the distinctive marine air horn sound recognized across waterways, while current draw specifications (typically 10-20 amps depending on model) ensure compatibility with most vessel electrical systems without requiring dedicated circuits or upgraded wiring.
