Optimize baghouse performance
Explore Sefar’s video series covering common pulsejet baghouse challenges, from installation and maintenance to troubleshooting emissions, differential pressure and premature bag failure.
Baghouse Theory and Function
Walk through the air/gas stream path from process to and through the baghouse. Then discussion of fabric selection, can velocity, differential pressure, and the cleaning cycle.
Ever wonder how the pulsejet baghouse works?
Want to know more than just the dust bag part number?
What this video covers:
- How air and gas move through a pulsejet baghouse
- How filter media captures particles and forms a dust cake
- Key pulsejet baghouse components and their functions
- Bag-and-cage vs. pleated bag configurations
- Why can velocity matters
- How differential pressure can indicate operating issues
- How the pulsejet cleaning cycle removes accumulated dust
Installation and Conditioning
Explore the airflow path and cleaning cycle, snap band construction and fit, bag to cage fit, precoating/seasoning/ conditioning new bags, and helpful pointers.

Troubleshooting Tools
Set your team up for successful troubleshooting with the right instrumentation, tools, and logs. We discuss selecting the appropriate fibers and finishes for your application, leak detection, and Sefar’s lab testing for failed bags.
What’s in your baghouse troubleshooting toolkit?
How do you know what to fix when your dust collector is down?
What this video covers:
- Key data and instrumentation for baghouse troubleshooting
- How maintenance logs and inspections can reveal failure patterns
- How leak detection can help identify filter bag and sealing issues
- How fabric and surface characteristics affect filter performance
- What failed filter bag analysis can reveal
- How Sefar's lab tools help investigate filter failure
Troubleshooting High Differential Pressure
There is an ideal difference in pressure between the dirty air side and the clean air side of your pulsejet baghouse. We’ll look at what cleaning systems, mechanical failures, process upsets, and chemical attacks can contribute to high DP and what to do about it.
Are you pulsing too frequently?
Is your cleaning cycle failing to recover your filter bags
What this video covers:
- Cleaning system issues
- How to test your cleaning system
- Finding your optimal low pulse pressure
- Causes for bag blinding
Troubleshooting Excess Dust Emission
We’ll discuss sources of particle bypass, how to prevent some, and repair the others.
Is your tubesheet dirty?
Are you facing fines for emissions?
What this video covers:
- Membrane care during install
- System leaks as emission sources
- What makes a good bag seal
- Retaining a good dust cake
Troubleshooting Poor Pulsejet Bag Life
There are three types of pulsejet filter bag failures; thermal, chemical, and mechanical. We’ll go over each and how to overcome them.
Seeing something strange in your baghouse?
Pulling dust bags early due to holes?
What this video covers:
- Chemical attack
- Hydrolysis
- Thermal attack
- Mechanical failures by
- Abrasion
- Blinding
- defects
Measuring and Test Fitting Pulsejet Bags
We lay out proper bag to cage fit, measuring tubesheet holes, measuring top and bottom load bags, and installing top and bottom load bags. This video is available on https://sefar.us/lp/dust-bags-us without an invitation.
