Dust collector filter bag

for dust filtersfor airnylon

Overview
SEFAR dust filter bags are engineered for dust extraction in grain and flour milling operations. They support clean processing areas and regulatory compliance by providing reliable dust separation and sustained performance under continuous exposure to flour and grain dust.

Benefits

• Emission compliance: Helps mills meet strict dust emission limits and supports workplace safety.
• Consistent filtration: Stable dust retention and extended service life in continuous milling operations.
• High air permeability: Optimized needlefelt structure for high airflow with low pressure drop in high-throughput systems.

Configurations & Installation Types

• Side loader: Open-top design with round bottom for easy insertion and secure sealing in compact filter housings.
• Top loader: Integrated collars and round bottom for rapid vertical installation in top-access collectors.
• Custom sizes: Fabrication to match collector dimensions for top- or side-loader configurations.

Filter Media
SEFAR TETEX® NF is a needlefelt specifically developed for dry flour and grain dust. Available for both top- and side-loader systems, it ensures stable filtration performance. Optional variants include food-contact-compliant materials (FDA / EU) and metal mesh or PA/PET blends for specific process requirements.

Sealing, Reinforcements & Finishes

• Sealing options to reduce flour dust emissions and maintain negative pressure for stable filtration.
• Reinforced edges to improve fit and sealing strength.
• Optional finishes: antistatic treatments and oil/water-repellent coatings to support safe operation in ATEX-zoned areas and improve cleanability for sticky or oily dusts.

Product Features

• FDA & EU food compliance: Materials available to meet FDA Title 21 and relevant EU food-contact regulations for hygienic milling processes.
• Explosion safety: Antistatic options for use in ATEX-classified zones where fine dust presents explosion risk.
• High-quality needlefelt: Durable construction for long service life and reliable dust retention.
• High air permeability: Fabric structure optimized for efficient dust extraction with low pressure drop.
