This month's tip focus on how to determine if installing pleated filter elements in your baghouse dust collector is right for your application. Factors to consider are air-to-cloth ratio, if moisture is present, and differential pressure settings. In the right application they can be a good upgrade for existing systems.
Pleated Filters for Baghouse Applications Video Transcript:
Hello, I’m Luis Castano, Applications Engineering Manager with an IAC tip of the month. Today we’re going to talk about pleated filters and their use in baghouse dust collectors.
Pleated baghouse filters came out about 25 years ago, and as the best new thing and it is a good product, but it does have its limitations. As an engineer I'm going to have to say that if you can avoid the pleated filters, it's a better option just to avoid it on a new system. But they're always available for the possibility of upgrading existing equipment.
Pleated filters can give you more capacity, but we cannot deny the deficiencies of having this pleated shape, which can accumulate material especially on a system that has moisture. If there's moisture try to avoid pleated filters.
Also, if you run pleaded filters at a high differential pressure for a long time, you may get pleat packing, which means that the pleat collapses, and you cannot get air flow through.
Use pleated filters wisely! We can help you determine if they're a good upgrade for your baghouse application, or if it's definitely not recommended because we want to avoid problems in the future. If you want to discuss the subject in more detail, please contact one of our IAC Engineers. Thank you!
