PBF Filters
The Pleated Belt Filter (PBF) is a revolutionary design that combines high capacity pleated media with high efficiency suction cleaning. The result is a high efficiency self-cleaning filter offering more capacity for its size than any other filter on the market.
Unlike filters that rely on building a fiber mat to retain small dust particles, the PBF does not. And unlike felt bag or cartridge filters, it does not blow or pulse dust back into the air stream.
For the first time, thorough automatic cleaning of agglomerated fibers and dust out of dense pleated high efficiency filter media is possible.
Features and Benefits
- High filtration efficiency: The media is optimized for fibrous dust filtration.
- High media cleaning efficiency: Fiber and dust are suctioned away out of the air stream (off-line cleaning).
- Compact size: A 85,000 m3/hr (50,000 CFM) filter is 3 m high x 3.5 m wide x 1.9 m deep (10 high x 11.3 wide x 6.3 deep).
- Saves money: In many cases, the PBF does the work of tandem filters. Also, cleaner air requires less air turnover and improves air conditioning system efficiency.
- Installation is simple, quick, and economical: The PBF is preassembled on a steel base and prewired, including controls. It does not require a smooth floor or elaborate leveling.
- The PBF is mechanically very simple: Each filter cell is basically a conveyor. No moving parts (except for the media itself) are on the dirty side of the filter.
- The cleaning mechanism never touches the media: No nozzles to adjust and wear out or rub holes in the media.
- Long lasting media: in normal operation, the PBF requires little or no attention for about two years, on average.
Applications
The PBF provides outstanding filtration performance for any air stream containing fiber and dust. Applications include:
- Textiles
- Non-wovens
- Pulp and paper
- Wood products
To determine if the PBF is suitable for your application, MikroPul maintains a full scale test facility at our plant in Charlotte. Contact your MikroPul representative for a performance test on your dust.
Operation and Maintenance
The PBF is automatically controlled and normally does not require operator intervention. In the unlikely event of a controller failure, a manual override mode allows operation by hand.
No tools are required for media changeouts. The filter cells are held in place with toggle clamps and the media is attached via Velcro strips.
Options
- PTFE membrane media: providing 99.97% efficiency, 0.5 micron and larger (standard spun bond media provides 95% efficiency).
- Weatherproof PBF housing: for outside installation.
- PLC-based controller: for interfacing with central monitoring stations.
- Controller with timer: for timed cycle media cleaning.
- Dust Handling: various methods for handling dust at discharge points.
- The Pneumatically Sealed Drum Cover: provides a simple solution to a common problem: leaking when discharging into drums. It features an inflatable bladder seal that creates an airtight seal even with out-of-round or dented drums.
- Screw Compactor: containing a helical screw conveyor designed to compact fibrous dust. This simple, effective device achieves about 5:1 compaction and can handle about 180 kg/hr (400 lb/hr) of stripped dust.
- Briquetter: provides a simple, clean and efficient way to dispose of your dust. It compresses fibrous dust into compact, easy to handle briquettes. They can be used or sold as fuel, and eliminate the need for plastic bags or special disposal arrangements.
