SEFAR® PHARMA GMP bags

Safety Built into Every Filter Bag

SEFAR® PHARMA GMP bags are developed in close collaboration with leading pharmaceutical manufacturers for the strict demands of pharmaceutical powder processing. Each filter bag is manufactured in a clean controlled environment following strict GMP guidelines according to FDA/EU standard.

Designed for spray dryers, fluid bed dryers, micronizers, Nutsche filters, and related equipment, these tailor-made bags feature particle-tight seams, antistatic materials, and safe edge designs. They offer maximum product protection and recovery, full compliance, and efficient, trouble-free operation.

 

• High-Quality Needlefelt
  High-quality SEFAR® TETEX NF PHARMA needlefelt (PET or PTFE) provides mechanical strength and reliable filtration performance.
• High-Performance ePTFE Membrane
  The integrated ePTFE membrane ensures excellent particle retention, low pressure drop, and minimal fiber shedding for clean, compliant product recovery.
• Conductive Stainless-Steel Matrix
  A built-in stainless-steel matrix enables safe dissipation of electrostatic charges, supporting ATEX compliance in explosive powder handling environments.
• PET or PTFE Scrim
  A durable PET or PTFE scrim reinforces the bag structure, providing dimensional stability and mechanical strength for consistent, long-term use.
• Equipment compatibility
  SEFAR PHARMA GMP bags are compatible with equipment from leading manufacturers, including GEA, Hosokawa, Piab, PSL, and TetraPak, .

Made to Perform

• Edge Protection
  A high-performance folded edge design prevents product contact with needlefelt fibers, minimizing contamination risk and supporting clean, compliant operation.
• Bottom Disc Design
  Our specially engineered bottom disc prevents needlefelt fibers from being pulled through to the product side, ensuring safe powder containment during handling and discharge.
• Top Connections
  Tailor-made top connections, including snap rings, steel rings, and other formats, enable secure, trouble-free installation across all major equipment.
• Custom Design
  Filter bags are designed to customer specifications. From geometry to construction, each bag is manufactured to precisely match your equipment design.
• Packaging and Labeling
  Each bag is individually packed and custom labeled, ensuring hygienic handling, full traceability, and compliance with pharmaceutical documentation standards.

Fully Controlled Production Chain

Sefar controls every step of production, from monofilament yarn extrusion to the final filter product. This vertical integration allows us to tailor filtration solutions to the specific needs of life science applications, ensuring consistent quality and regulatory compliance.

Cleanroom Manufacturing and Traceability

SEFAR® PHARMA GMP products are manufactured in cleanroom environments (GMP Class D / ISO Class 7), then individually packaged and sealed to avoid contamination. Each product includes clear identification for full traceability, safe handling, and reliable use in critical environments.

Quality Assurance and Regulatory Support

Our dedicated quality assurance team ensures each product meets strict standards through comprehensive testing for extractables, migration, and mechanical performance. Backed by full documentation, our filters simplify audits and support your compliance with GMP, FDA, and EU regulations.
