needlona® Needle Felt Filter Media
High-performance needle felt filter media manufactured by BWF Envirotec on reinforced supporting scrims for superior dust collection efficiency.
- Available in fibers: PES, PP, PAN, Meta-Aramid, PPS, Polyimide P84, and PTFE
- Advanced surface finishes for oil and water repellency, spark resistance, and thermal stabilization
- Dimensional stability and extended operating lifetime in harsh baghouse environments
- Engineered for Pulse-Jet, Shaker, and Reverse-Air industrial dust collectors
PM-Tec® Filter Media with ePTFE Membrane
Premium filter media laminated with a microporous ePTFE membrane for high-efficiency surface filtration of submicron particles.
- ePTFE membrane layer guarantees surface filtration and emission levels below 1 mg/Nm3
- Low operating pressure drop and rapid cleaning cycle reducing compressed air consumption
- Substrate available in needle felt or woven fiberglass for aggressive gas streams
- Ideal for chemical, pharmaceutical, metallurgical, and cement fine dust emission control
Pyrotex® KE High-Temperature Ceramic Filter Elements
Rigid self-supporting ceramic filter elements engineered for hot gas filtration and spark-laden flue gas dedusting up to 850 deg C.
- Continuous operating temperature resistance up to 850 deg C with zero burn-through risk
- Completely immune to sparks, glowing embers, and aggressive acid gas components (SOx, HCl)
- Optional integrated catalyst for simultaneous dust removal and catalytic DeNOx / dioxin reduction
- Rigid self-supporting structure eliminating internal wire support cages
Filter Bags for Asphalt and Cement Industries
Dedicated AsphalTec® filter bags and heavy-duty sleeves designed for asphalt mixing plants, cement kilns, and clinker coolers.
- AsphalTec® series resistant to moisture, bitumen vapors, and thermal cycling up to 200 deg C
- Reinforced wear cuffs and double-stitched bottoms for high-abrasion clinker dust
- Compatible with asphalt plant filters: Ammann, Benninghoven, Lintec, Ermont, Teltomat
- Optimized gas permeability preventing premature filter blind-off
Support Cages and Envirojet Venturi Nozzles
Precision wire filter cages and aerodynamic venturi nozzles designed to maintain optimal bag shape and pulse-jet airflow efficiency.
- Available in round, oval, flat, and star configurations with 8 to 24 longitudinal wires
- Fabricated in galvanized mild steel, stainless steel 304/316L, or silicone resin coated
- Sectional split cages with bayonet or claw connectors for restricted overhead clearance
- Envirojet aerodynamic venturis maximizing cleaning energy along the entire filter bag length
Venturi Gaskets, Snap-Rings, and CS30 Sealing Rings
High-temperature sealing collars and venturi neck gaskets fabricated from BWF PI/PTFE 554 MPS CS30 composite material.
- Venturi gasket 125x165x2 mm in PI/PTFE 554 MPS CS30 (ref. EFB.9999.R125165.CE02)
- Spring steel Snap-Ring collars ensuring gas-tight sealing against the cell plate
- Prevents dust bypass and leaks around filter bag top sheet openings
- Thermal and chemical compatibility matching the filter bag sleeve material
FoodTec® Food-Grade and ExCharge® Antistatic Filter Bags
Specialized BWF filter media certified for food/pharma contact (EC 1935/2004, FDA) and explosive ATEX dust atmospheres.
- FoodTec® compliant with EU Regulation 1935/2004, EU 10/2011, and US FDA standards
- Zero fiber release and food safety for dairy, sugar, starch, flour, and pharma powders
- ExCharge® certified by DEKRA with electrical resistance below 10^6 Ohms
- Eliminates electrostatic discharge risks in hazardous dust environments
