The Prestige 100ZGHS bathroom fan with automatic backdraft damper, humidity sensor, and timer offers effective air circulation for bathrooms, toilets, and other enclosed spaces such as storage rooms. This white, square device features a 100 mm diameter connection with a maximum air output of 97 m³ per hour at a sound level of 39 decibels. Designed for wall mounting, the fan has a build depth of 85 mm and front dimensions of 160.5 mm in height and 160.5 mm in width with a front thickness of 32 mm. The ventilation system offers several operating modes: manual switch, timer function, and automatic humidity sensor activation that responds to humidity levels to prevent condensation and mold formation. An integrated automatic backdraft damper prevents backflow when not in operation, maintains heat efficiency, and avoids unwanted air exchange. Constructed with a durable plastic housing, this AC motor operates at 2400 revolutions per minute with a power consumption of 15 W at 230 V and 50 Hz frequency. The device weighs 0.4 kg and requires professional installation into existing ventilation ducts. This ventilation solution provides reliable performance to maintain air quality in humid environments without the capability for ceiling mounting.
