The HWS5 series explosion-proof wind direction bag is a core safety indicator device specialized for hazardous areas such as ships, offshore platforms, heliports, and petrochemical industries. It can intuitively and accurately display real-time wind direction and relative wind speed, assisting pilots, commanders, and field operators in accurately assessing airflow conditions in flammable and explosive environments, ensuring safety and efficiency during helicopter takeoffs, landings, and personnel operations. The product is designed according to the CAP437 standard, fully meeting the strict requirements for wind varne bag performance, color, lighting, and fire resistance, while also meeting the "MH5013-2023 Technical Standard for Civil Heliport Flight Sites."
Relevant regulations and must possess explosion-proof certification qualifications.
