Dust Filter Requirements
Production processes in the Food, FMCG, Chemical or Pharmaceutical Industries often come together with complex Dust or Vapor Extraction processes. Standard Filters are easy to buy but more often than not perfectly suited for your operations leading to unwanted situations like:
- Over-extraction
- Under-extraction
- Downtime due to maintenance
- Explosion Risks
- Clogging & Bridging
For effective filtration, filters should be selected on the following criteria:
- Efficiency in Filtration
- Simple to operate
- Adjusted to your site’s specific requirements
- Suitable for your product
Industrial Dust Filtration done right
JOA sees Filters as a part of the whole extraction system that needs to be investigated before the right Filter choice can be made. To determine the appropriate filter size, every individual installation needs to be modeled, to determine:
1. The optimal Air-to-Cloth ratio (speed of impact of dust particles against the filter cloth)
2. The Interstitial velocity (function of bulk density, particle size distribution, dust agglomerating, and inlet loading). This provides competitive economics (standardized production) in combination with individual design, (optimal filter element spacing) for long filter lifetime.
3. Selecting the best filter media (after in-house lab testing). in most applications using felted or membrane nonwoven materials, emission values of < 0.1 mg/m3 are possible. In the event of combustible dust (KST Value & MIE), all JOA filters can be equipped with explosion venting for ATEX/Explosion Safety certification.
Selection of JOA Filters
- Bag Filters
- Belt Filters
- Envelope Filters
- Pocket Filters
- Activated Carbon Filters
- Powder Conveying Filters (Acoustic CiP)
For optimal economics, JOA manufactures a standardized modular filter housing, that can be equipped with envelope filters, pleated filter elements and bag filters to serve many different dust collection applications.
Since 1998, JOA has designed and built over 2000 dust filtration systems for handling industrial dust emissions and effectively eliminating ultra-fine particulates (UFP’s). The primary purpose of these systems is to provide a healthy work environment and to enable NeR, TA Luft, and EPA-compliant emissions.
