Piab Conveying Filters

Piab textile filters are antistatic filtration elements designed to efficiently remove dust and fine particles from the vacuum flow while maintaining high permeability and stable conveying performance. As one of the most cost-effective and widely used filter solutions in Piab’s range, textile filters are particularly suitable for conveying powders, fine powders, granules, tablets, and materials prone to caking or bridging.

The filters feature welded seams to ensure durability and consistent quality, while the antistatic design supports safe operation in demanding environments. Textile filters comply with FDA and EU food contact regulations and are suitable for use in ATEX-classified applications according to specifications. Due to their versatility and reliable performance, textile filters are widely used across industries, especially in food and beverage production, as well as pharmaceutical and general industrial applications

Piab standard air inlet filters prevent airborne dust and particles from entering vacuum conveying systems through adjustable feed adapter air inlets, ensuring clean and contained material transport. At the same time, they prevent conveyed material from escaping during processes such as fluidization, reducing product loss and contamination risks.

Designed for low airflow restriction and high filtration efficiency, the filters feature a robust construction with corrosion-resistant coating and easy element replacement. With high removal efficiency down to 5 microns and a wide operating temperature range, these filters are suitable for general industrial applications including chemical processing, additive manufacturing, blending and mixing operations, reclaim systems, and tablet handling processes.

Piab sintered PE filters represent a next-generation filtration solution designed for demanding powder handling applications. Manufactured as a PFAS-free unibody sintered polyethylene element, the filter combines high mechanical strength with consistent filtration performance and long service life.

The compact twisted geometry maximises filtration area while maintaining reliable airflow, making the filter suitable for fine powders and challenging process conditions. The washable, reusable, and sterilizable design simplifies maintenance and supports hygienic operation, while the integrated NFC chip enables traceability and digital filter management. These filters are particularly suited for food and beverage, pharmaceutical, and chemical industries where compliance, durability, and process reliability are critical.

Piab pleated filters provide the largest filtration area within the filter range, making them ideal for conveying extremely fine and free-flowing powders. The increased filter surface improves airflow capacity while maintaining effective dust separation, ensuring stable conveying performance even with small particle sizes such as toner or fine powders.

The filters are antistatic and comply with FDA and EU food contact regulations, supporting safe operation in regulated environments. Pleated filters are commonly used in industries handling fine powders, including food processing, pharmaceuticals, chemicals, and additive manufacturing applications where high filtration efficiency is required.

Piab pleated stainless steel filters are designed for applications requiring sterilization and enhanced chemical resistance. The robust stainless steel construction allows repeated cleaning and sterilization processes, making these filters particularly suitable for pharmaceutical, nutraceutical, and chemical industries.

The filters are optimized for conveying tablets, powders, and granules larger than 5 µm while maintaining reliable airflow and filtration performance. Antistatic properties and compliance with FDA and EU food contact regulations support safe use in regulated production environments where hygiene and durability are essential.

Piab PFAS-free pleated rod filters are heavy-duty filtration solutions developed for demanding applications involving fine powders and challenging dust conditions. The rigid construction ensures durability and stable performance, while the PFAS-free coating supports environmental compliance and safer material handling.

Designed for efficient filtration of small particle sizes such as toner and fine powders, the filters are available in both ATEX-compliant and non-ATEX variants to match different operational requirements. These filters are widely used in chemical, pharmaceutical, and food and beverage industries where safety, compliance, and sustainability are important factors.

Piab antistatic air inlet filters provide controlled airflow while preventing dust ingress and product leakage through conveyor feed adapter air inlets. By maintaining contained material transport and preventing cross-contamination, the filters improve both process cleanliness and operational safety.

Constructed from corrosion-resistant stainless steel grade 316, the filters offer high filtration efficiency with minimal pressure drop and simple maintenance through replaceable elements. Their antistatic design supports safe use in ATEX-related environments, making them suitable for demanding applications in chemical processing, pharmaceutical production, food and beverage manufacturing, and additive manufacturing systems.

The Piab second-stage filter unit is designed for applications involving extremely fine or hazardous materials where additional filtration is required. Installed between the conveyor and the pump, the unit provides secondary sterile filtration using ULPA filters capable of capturing particles down to 0.2 µm.

This solution enhances system safety and protects downstream equipment while ensuring compliance with strict hygiene and containment requirements. The complete, ready-to-use unit is easy to assemble and compatible with piFLOW^®p, piFLOW^®fc, and piFLOW^®t conveyors. Second-stage filter units are ideal for pharmaceutical, chemical, and high-containment applications where fine particle control and regulatory compliance are essential.
