There are 5 primary steps you should go through when ordering a filter bag.
The main type of dust filter bags including Nomex filter bag ,PPS filter bags ,P84 filter bag ,PTFE filter bags ,Acrylic filter bags ,Polyester filter bags,dust filter bag ,bag filters,dust collector bags.
Step. 1 MATERIAL SELECTION
You should choose the media from which your filter bags dust filter bag 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
Choosing the correct filter media is an important and sometimes difficult process. To assist you in the identification of the right media for your bags, keep the following in mind:
Filter bag dust filter bag performance is directly related to how well it can tolerate the environment in which it is being used, how efficiently it can remove the dust particles and it’s ability to clean and renew.
You must first learn to identify the type of filter media currently used in your application. Below you will find a list of typical construction methods:
-
Thermoplastics
- Polypropylene (PP)
- Polyphenylene sulfide (PPS)
- Polyester (PE)
- NOMEX
- PTFE
- P84 ,POLYIMIDE
- Thermoset
For additional information on media types please examine our sample chart
A simple test to determine if a material is a thermoplastic is to take a small swatch and put a flame to it. A thermoplastic material will begin to melt when exposed to direct heat.
The selection criterion eliminates materials based on temperature and chemical characteristics.
The first cut is usually made based on temperature.
Then the chemical characteristics of the gas stream are considered to further refine the search. Chemical Resistance.
Next, the efficiency of the material further dictates the construction of the material i.e. – the weight – oz/sq. ft., fiber and surface treatments/membranes.
Last but not least, if there are still two or more candidates it comes down to a price versus performance trade off.
Step. 2 MEASUREMENTS
(get accurate measurements for optimal performance)
Most dust collectors have been upgraded over the years due to the need for new permits which called for reconfiguration of the bag house in which case OEM configurations will have changed. Because of this you will need to obtain accurate measurements for your filters before ordering replacement filter bags. filter bags dust filter bag.
If you currently have filter bags ,dust filter bag installed that are functioning properly, you can pull out one of those bags to get the proper measurements for your replacement order. (spare bags 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) It is best not to pull the numbers off the unit because of possible changes to the configurations. e
GRACE Filter P84 Filter felt has excellent superfine particle collecting efficiency and small operating pressure difference.
It is usually used in gypsum plant, cement plant, waste incinerator, liquid bed boiler, coal-fired boiler etc.
