Introduction

We have innovated water rescue tools with a focus on enhancing the efficiency and safety of rescue teams. Specifically designed for firefighting and community-based humanitarian rescue teams, we have created a specialized stainless steel propeller. Unlike traditional propellers, we use high-hardness 2205 duplex stainless steel to provide exceptional stability for watercraft.
The unique design includes special angles at the propeller's tips and tails, offering more powerful thrust to the watercraft while reducing the accumulation of exhaust fumes, effectively preventing propeller cavitation. Additionally, the glossy and sleek appearance, combining engineering with artistry, ensures outstanding performance. Rescue teams can now benefit from a more stable and efficient water rescue tool.
After extensive field testing, our stainless steel rescue propeller demonstrates performance beyond traditional ones. It generates more powerful thrust, allowing fully loaded watercraft to swiftly navigate through complex water conditions and significantly reduce cavitation effects. Propeller damage and replacement are common challenges in actual rescue operations. Our innovation not only increases the durability of the propeller but also lowers replacement costs. In emergency situations like flooding, this innovation plays a crucial role, reducing economic costs and ensuring the immediate deployment of rescue materials, thus delivering remarkable social benefits.

Design by Chen Qi

Mr. Chen Qi, the current General Manager of AidSpeed, has been dedicated to the firefighting equipment manufacturing industry since 2007. With 14 years of experience in the technical field, he has undertaken several international trips to countries renowned for their strong manufacturing industries, such as the United States, Norway, Sweden, France, and Russia, to explore their firefighting equipment standards. He has also actively participated in knowledge exchange programs organized by the China Fire Protection Association, the U.S. Department of Commerce, and the Irish Department of Business. Mr. Chen Qi has meticulously studied advanced overseas technologies and fire and rescue concepts, taking into account the unique characteristics of China's firefighting and rescue departments. He has also sought feedback and suggestions from frontline Chinese firefighters.
In just three months, all the knowledge and recommendations gathered over the past 14 years, from both his professional experience and frontline firefighters across the country, were condensed into the first-generation "WSAR" series of rescue products.
Following the production of the initial watercraft, our technical team skipped calm reservoir testing and conducted destructive experiments in harsh conditions, including highly corrosive seawater, scorching sunlight, and waves of nearly 2 meters. These experiments were compared to other mature foreign-manufactured products. After rigorous testing and continuous improvement, on April 28, 2021, our products made their first appearance at a water rescue exercise organized by the Hubei Provincial Firefighting and Rescue Brigade. The immediate response and acclaim from on-site firefighters were highly encouraging. The exercise was broadcast live by national media, including CCTV, and on various platforms such as Douyin, Tencent Video, and WeChat, spanning a continuous 36-hour broadcast. According to the requirements of the Hubei Fire Brigade, a rapid rescue boat was needed to complete a water rescue project.
