Ventria This transparent top-hung window provides natural ventilation for both smoke and hot air. Thanks to its attractive external design the Ventria is often integrated into glazed facades and glazed roofs for air feed and air extraction.

Kingspan Ventria 3 Versatile top or bottom hung ventlight Technical Specifications Designs The Ventria is a hinged ventlight that can be incorporated into glazed roofs and glazed walls. The opening angle of the window in relation to the base structure is variable up to a maximum of 70°. The structure consists of tempered aluminium, sea

The hatch vent AOV provides discharge of smoke and fumes with an opening angle of 140 degrees. It is available with either a solid aluminium insulated lid or a polycarbonate translucent panel. The latter option can provide daylighting if required. The roof hatch is not usually suitable for environmental ventilation. Actuated vertical window

An AOV system is a control system designed to vent air or smoke from a building. AOV control systems are used mainly to control the ventilation of smoke in a fire. Changes to building regulations were made due to the results of investigations into smoke inhalation.

The Ventria is a low cost solution for glazed applications where concealed controls are not required. The ventilator can be used both for smoke and day-to-day ventilation. The Ventria extracts large volumes of smoke, utilizing the buoyancy of hot gases in the rising plume.

Automatic Opening Vent (AOV) Rooflights are electrically operated natural smoke and heat exhaust ventilators (NSHEV) that allow natural light into a building. They can also be used for comfort ventilation as well as roof access. Designed for easy installation on flat roofs up to 15°, the units open to 140° in less than 60 seconds.

2025年2月7日，美国联邦巡回上诉法院对武汉禾元生物技术股份有限公司（简称 “禾元生物”）与美国国际贸易委员会（ITC）、Ventria Bioscience公司（简称“Ventria公司”）之间的专利侵权纠纷案作出判决，维持ITC此前的裁决，认定禾元生物临床级白蛋白产品侵犯Ventria公司的专利，且Ventria公司满足美国国内产业要求。 正在科创板IPO审核阶段的禾元生物，在2024年12月31日更新了招股书，其中记载了有关本案在此之前的最新进展。

2024年4月12日 · AOV基于SoC厂商的技术，内置AI算法，通过抓拍图片，识别目标，实现主动定时检测（常规低功耗摄像头的PIR为被动检测触发），监控场景能更大（30米距离，常规PIR及微波方案一般是10米），准确度更高。 减少漏报，错报。 不间断抓拍的图片与报警之后唤醒摄像机全帧率录像相结合，能保证摄像机24小时录像不断（比如，可能是1fp@s+25fp@s的结合体）。 同时不间断抓拍图片，从而能实现常规摄像机的软光敏功能（控制补光灯开启，双光警戒报警等） …
