Step.1 MATERIAL SELECTION
(choose the right filter media for your application)
You should choose the media from which your filters will be constructed based on the type of application they will be used for. Take the following things into consideration prior to selecting your media:
- Temperature – do your bags need to withstand extreme temperatures
- Product – what are you filtering
- Chemistry – can your bags withstand the chemical make up of the dust particles
- Resistance- is the filter media able to resist the wear and tear of the dust particles
- Partical size-The micron distribution of the particulate being filtered
We can help youi dentify the type of filter media currently used in your application. Below you will find a list of typical construction methods:
- Woven felts
- Non-woven felts
- Natural fibers
- Polypropylene (PPRO)
- Polyphenylene sulfide (PPS)
- Polyester (PE)
Step. 2 MEASUREMENTS
(get accurate measurements for optimal performance)
Most dust collectors have been upgraded over the years rather than replaced due to the need for new permits and the hassles with that process. That creates issues where OEM configurations will have changed. Because of this you likely will need to obtain accurate measurements for your filters before ordering replacement filters.
If you currently have filters installed that are functioning properly, you can pull out one of those filter to get the proper measurements for your replacement order. (spare filters not yet used can also be measured if available) If you are removing a used bag to measure, please be sure to use all necessary precautionary measures set in place prior to removal (i.e. – gloves, protective garments, & respiratory equipment if needed).

Step. 3 and 4 TOP & BOTTOM CONSTRUCTION
The top and bottom construction of a filter bag involves a variety of possible configurations. The type of cleaning process used by the dust collector determines which configurations will be used in the design of the filter bag.
