The circular duct fan is an ideal ventilator with perfect combination of performance and appearance. The ingenious cooperation between the newly designed casing and the backward tilting centrifugal impeller maximizes the gas fluid mechanics, and its shape is small and very practical. It has the characteristics of easy installation, light weight and low noise. Provides source power for air supply, exhaust, return air and air purification treatment. Ultra-high wind pressure can be connected to tens of meters of pipelines. A fan controls centralized ventilation in multiple areas. It is generally used in buildings and indoor ventilation Or pressurize the pipe. The circular duct fan can be connected to the same size of pipe on both sides, and one side is in and the other is out.
Features:
1、Combined with advanced concepts, new design housing and aerodynamic design impeller, can effectively reduce vibration and noise
2、Same dimension inlet and outlet, fan can be directly connected with duct
3、Adopted impeller by integrate new plastic bade with metal baseboard
4、Integrated impeller and exterior rotor motor , through air flow efficient cooling can extend the fan lifetime
5、Three speeds control, through keeping current waveform smooth to reduce the noise and vibration, with automatic reset thermal protective device for electricity management; light weight, stable running, high efficiency, long lifetime
