Product Description
Marine Fog-signal Airhorn Type WD-1A
Product Introduction
The Marine Fog-signal Airhorn Type WD-1A is a high-decibel, corrosion-resistant audible signaling device designed specifically for vessels operating in low-visibility conditions. Engineered to comply with international maritime collision regulations (COLREGs), this airhorn delivers a deep, penetrating tone that ensures your vessel is heard clearly over long distances, even through dense fog or heavy rain.
Constructed from marine-grade aluminum and stainless steel, the WD-1A is built to withstand the harshest saltwater environments. Its robust diaphragm mechanism requires minimal maintenance while providing instantaneous sound emission upon activation. Whether connected to a built-in air compressor or a standalone air tank system, the Type WD-1A offers reliable performance for small boats, yachts, and commercial workboats.
