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.
|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|
|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|
|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|
