Air shower ventilation fan pressure level and wear resistance Apr 08, 2018

During the development of the air shower ventilation fan, in order to further improve the aerodynamic efficiency, device efficiency, and use efficiency of the device, the power consumption of the air shower fan can be reduced to a certain extent. The axial flow fan with adjustable blades replaces the large centrifugal fan.

The air shower ventilation fan can effectively reduce the noise of the ventilator during operation, so that the exhaust resistance of the exhaust fan and the casing of the ventilating fan can be effectively improved to some extent. Effectively realize variable speed adjustment and automatic adjustment.

Air shower ventilation fan pressure level

1. The low-pressure centrifugal fan, in the process of operation, the fan inlet standard is the atmospheric condition, and the ventilator's full pressure PtF ≤ 1kPa centrifugal fan.

2. In the medium-pressure centrifugal ventilator, the fan's inlet is the standard atmospheric condition during operation, and the ventilator's full pressure is a centrifugal ventilator with a pressure of 1kPa<PtF<3kPa.

3. High-pressure centrifugal fans, whose fan inlets for the entire equipment are standard atmospheric conditions.

4. Low-pressure axial flow fan, fan inlet is a standard atmospheric condition, and the total pressure of fan is axial flow fan with PtF ≤ 0.5kPa.

5. High-pressure axial flow fan, fan inlet is a standard atmospheric condition, and the total pressure of the fan is an axial flow fan with 0.5kPa<PtF<15kPa.
