Blower Fan Static Pressure

Our high pressure blower designs are considered heavy duty high quality durable equipment.

Ceiling fan installation in tamil. Static pressure created by the hood to get the total static pressure of the system. High static pressure fans and blowers tend be louder versus standard cooling solutions and must be taken into account during the enclosure or package design phase. 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.

As pressure differential across it increases the power used increases even as the airflow it produces decreases. With 45 of suction pressure on the inlet and 12 of discharge pressure on the discharge the total static pressure 50312 623 inwg. If the fan or blower will be handling a gas or vapor with a density that is less or greater than standard air contact our sales office for your area for fan sizing.

Density at standard conditions 5. Altitude feet above sea level steps 5 and 6 below. Fan static pressure fan discharge pressure fan inlet pressure velocity pressure static pressure is measured by a water gauge wg and is an indication of the air flow resistance inside your fan.

Static pressure in. Theres more to choosing the right pc fan than picking a size noise level and bearing type. A four foot hood with an opening of 48 inch wide by 15 inches high requires 100 fpm face velocity.

A blower wheel decreases in power used as static pressure increases unless there is a ecm motor changing the rpm to compensate. Best 120mm 140mm static pressure fans for radiators heatsinks and restricted spaces in pc case. With 45 of suction pressure on the blower inlet and no discharge pressure on the blower discharge the total static pressure 503 inwg.

Axial prop a prop fan performs in an opposite way in relation to pressure. Higher resistance takes energy away from the process. Air temperature 0 f to 0 f 6.

Static pressure the resistance to flow energy added by the fan measured in inches of water gauge in wg fan selection is typically based upon a cfm and static pressure ie. Hood static loss as given by the manufacturer is 025 inch wg. Linus explains the difference between high airflow and static p.

These high static pressure fans can deliver air at great force to the heat source and cools them down at a faster pace compared to standard fans. A 120mm high static pressure fan with airflow of 283 cfm can have a noise level of 70 db as compared to a standard 120mm fan with airflow of 105 cfm at 43 db. They primarily move clean air but they also have the capability to move some material laden air.
