Vent Axia Air Quality Sensor (AQS) 432953

The Vent-Axia air quality sensor provides automatic ventilation control by detecting a decline in air quality caused by tobacco smoke, unpleasant odours, or bathroom smells. Ideal for use in environments such as cinemas, restaurants, pubs, clubs, kitchens, toilets, and meeting rooms, it activates ventilation systems when air purity falls below an adjustable threshold. Detection is managed by a self-cleaning ceramic sensing element for reliable operation. This sensor is not designed for identifying combustible gases. It supports either MIN-MAX operation or direct damper control. Key features include a surface-mounted design, 1 to 25 minute overrun timer, and a supply voltage of 24V DC SELV. Operating temperature range is 0°C to +50°C, and dimensions are 87 x 157 x 47 mm (H x W x D).
