Frequently Asked Questions

Will this drain rust in a saltwater environment?
No. This drain is forged from premium 316 Marine-Grade Stainless Steel, which contains molybdenum for superior resistance to chloride pitting and saltwater corrosion compared to standard 304 steel.
What size hole do I need to cut for installation?
The drain is designed for a standard 50mm (approx. 2-inch) drainage opening. The outer flange measures 78mm to provide ample coverage and a secure seal against the deck surface.
Does this drain prevent debris from clogging the bilge?
Yes. The precision-engineered 5-slat grille acts as an integrated filtration system, capturing larger debris while maintaining a high-velocity water flow to keep your decks clear and safe.

Our Roots

Hong Kong Based, 8 Years of Expertise

Supply Chain

Invested Factories in Mainland China

To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.
