Different Baghouse Styles: Advantages and Disadvantages

When it comes down to finding the right baghouse, there are a few different styles to choose from. So how do you know which one is best for you?

Some of the elements you need to consider will be your dust properties and air-to-cloth ratio.  Baghouses are ideally suited for large volume applications with airflow exceeding 1,000 CFM or when high temperature applications are above 375 degrees.  In these environments, a baghouse will handle and most efficiently filter your dust laden air. 

There are three main styles of baghouses  (e.g. shaker, reverse, and pulse-jet)  that are commonly used in most industrial processing and manufacturing applications.  Here’s a brief overview on the pros and cons of each to help guide you in identifying the right option for your work environment.

Pulse Jet Baghouse

Pros:  Cons:
Constantly cleaned so there is minimal dust build up in the dust collector Requires dry compressed air
Space Efficient Cannot be used when there is humidity of high moisture content present
Requires fewer bags Cannot handle high temperatures (unless you use special filter media
   

Reverse Air Baghouse

Pros: Cons:
Can handle high temperaturesNeeds to be cleaned often
Gentle cleaning which allows for longer bag lifeResidual dust build up is hard to remove
Units are typically compartmentalized into sections which allows them to be cleaned without shutting off the entire baghouseLow air-to-cloth ratio
  

Shaker Baghouse

Pros:  Cons:
Very simple to operate  Cannot handle high temperatures
Low initial investment cost  Not space efficient (takes up a large area)
Units are typically compartmentalized into sections which allows them to be cleaned without shutting off the entire baghouse  Energy and time sensitive
