Different Baghouse Styles: Advantages and Disadvantages
When it comes down to finding the right dust collection system, there are a few different baghouse styles to choose from. So how do you know which one is best for you?
Before we dig into the differences between some of the baghouse styles, you need to consider 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 baghouses styles (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 temperatures | Needs to be cleaned often |
| Gentle cleaning which allows for longer bag life | Residual dust build up is hard to remove |
| Units are typically compartmentalized into sections which allows them to be cleaned without shutting off the entire baghouse | Low 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 |
