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
|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|
| || |
|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 |
