Parameter: Power: 300W; Speed: 1450r/min; Airflow: 2300m3/h; Hydrostatic pressure: 260 Pa; Exhaust port diameter: 250 mm. It combines the features and advantages of axial and centrifugal fan and effectively circulates air Centrifugal fan non-toxic and tasteless, environmentally friendly and healthy. Compared with ordinary motors, the improved motor can reduce the coefficient of friction, effectively save electricity and extend the life of the machine Long-lasting: Corrosion-resistant, wear-resistant, high temperature resistant. A stepless speed controller on the power cord allows the fan to rotate at different speeds; This speed switch allows you to set the desired airflow. Applications: Suitable for anti-corrosion fans for chemical gases, such as extractor hoods in laboratories and chemical cabinets. Low noise: With suction, low noise level of 40 decibels, will not affect your life and work. The fan blades rotate smoothly and powerfully, which helps to collect the airflow volume and reduce noise production, Manufacturer: OTENC
