WebHigh Pressure Systems- where fan static pressures are in the range 6 to 10 in WC (1500 - 2500 Pa) and duct velocities in general less than 4000 fpm (20 m/s) Medium pressure classification is commonly used for primary main ductwork like fan connections, risers and main distribution. WebThe controller uses a static pressure sensor located in the supply duct (at the end of the longest run) to modulate the supply fan to control duct static pressure. On a call for full pressure, the fan runs at full speed. As duct static pressure increases, the supply fan speed reduces. An optional discharge air static high limit reduces the fan ...
