High Static Pressure Exhaust Fan

Static pressure in fan systems is typically less than 2 sp or 0 072 psi.

High static pressure exhaust fan.

High airflow fans simply push as much air as possible while static pressure fans are specifically designed to tackle installations with heightened impedance and resistance. Our high pressure blower designs are considered heavy duty high quality durable equipment. A pressure differential between the duct and the atmosphere will cause the water level in the manometer legs to rest at different levels. In an lpcv barn the airflow rate of an exhaust fan and the static pressure must equal the total sum of the resistances caused by the inlet system inlets and evaporative cooling pad plus the resistance caused by baffles in the barn.

It s affected by things like the size and state of the ductwork surrounding your fan as well as air temperature altitude and whether or not the fan is material handling. When dealing with high static pressure it is a safe bet to use high pressure blowers you will find the term used interchangeably with high pressure fans. An exhaust fan s static pressure also known as its pressure drop describes the resistance the fan must overcome. The exhaust fan drawing below illustrates how static pressures are measured in ductwork with a manometer.

A larger static pressure forces the fan to consume more power to expel the same amount of air. Static pressure is measured by a water gauge wg and is an indication of the air flow resistance inside your fan. Higher resistance takes energy away from the process. Technicians typically measure static pressure in inches of water gauge.

They primarily move clean air but they also have the capability to move some material laden air.
