The fan is used for permanent and periodic ventilation of sanitary rooms, bathrooms, kitchens and other domestic premises. The rectangular faceplate is suitable for installation in ventilation shafts with a vertical opening, which are often found in Soviet-built houses. The fan meets the most stringent quality and safety standards. The protection level is IP24. The plain bearing motor requires no additional maintenance and guarantees efficient removal of moist and polluted air. STANDARD is equipped with a disposable fuse to prevent short circuits, a check valve to prevent dust and odors from the ventilation duct, an anti-mosquito net that protects the room from insects and dirt from the shaft. The ET control board with electronic timer allows you to customize the run time with switches; 5, 15 or 30 minute intervals. By default, the unit will run for 30 min after the switch is pressed. If necessary, you can change the operation interval to 5 or 15 minutes, or disable the timer. The housing is made of high quality and durable ABS plastic, which will reliably last the whole period of use and will not yellow. The fan is equipped with an LED to indicate the operation of the device. Mounting is carried out using self-tapping screws.
