The Importance of Static Pressure for Your Dust Collector

Static Pressure and Your Dust Collection System

Static pressure is the pressure created by a fan or other source to move air through a ventilation system and plays a critical role in the design and performance of pulse jet baghouse dust collection systems. Today we are discussing the importance of static pressure, what it is, how it’s measured, and how to calculate it.

What is Static Pressure?

Static pressure is used to determine the fan size you’ll need for your dust collection system. If the fan you choose for your system cannot handle the static pressure, air will not be able to move properly through the system and your dust collector will not be able to remove dust effectively.

How Static Pressure is Measured

Like differential pressure, static pressure is measured in inches of water and sometimes will be called water column. The abbreviation for this unit is usually seen as “w.c.” and can also be seen as “w.g.”

How to Calculate Static Pressure

To calculate required static pressure, sum the following components of a dust collector system.

  1. To start add 0.5” Second
  2. Add the filter resistance of the collector. This will be the maximum recommended differential pressure from a dirty set of filters.
  3. In most cases you can use 6” for a baghouse and 5” for a cartridge collector. Then add 1” If an outlet duct exists in the system.
  4. Fourth, add the friction loss in the duct system coming to the dust collector. For simple runs of 100’ or less, you can use 6” as a rule of thumb.

Please keep in mind these are general guidelines and there are many other variables to consider to make sure your system is engineered safely for your unique work environment to achieve peak performance.
