What is a Horizontal Negative Pressure Windshifter?
FYF Series Horizontal Negative Pressure Wind Sifter, also known as a horizontal air separator or negative pressure air classifier, separates lightweight materials from mixed waste streams by controlled airflow. It is used to remove plastic film, paper, textiles, and RDF fractions while improving dust control and sorting purity. The equipment is usually installed after shredders and screens, and works with conveyors, magnetic separators, eddy current separators, and optical sorting machines in recycling plants.
Xinzhongyi ECO designs and manufactures customized FYF Series Horizontal Negative Pressure Wind Sifters according to material characteristics, processing capacity, and plant layout. With 16+ years of recycling equipment experience, we provide equipment supply, process design, installation guidance, and commissioning support for complete recycling line projects.If you’re interested in “Horizontal vs. Vertical Wind Sifter Machine: What’s the Difference?”, please click here
Applicable Materials
FYF Horizontal Negative Pressure Wind Sifter is designed for separating lightweight fractions from mixed waste streams, including plastic films, plastic bags, paper, cardboard, textiles, wood chips, packaging materials and RDF components. It is widely used in MSW recycling, C&D waste sorting, industrial waste processing and RDF production lines to remove low-density impurities after crushing and screening. The system is suitable for processing mixed materials with feed sizes typically ≤150 mm, using controlled negative pressure airflow to separate lightweight materials from heavier fractions and improve the quality of recovered materials for downstream processing.
Working principle
The Horizontal Negative Pressure Wind Sifter uses a closed airflow system to remove lightweight fractions from mixed waste streams. The process improves material recovery efficiency and provides cleaner operation for recycling plants.If you want to learn about the working process and mechanism of a negative-pressure wind sifter, click here
Feeding System :Mixed materials are evenly delivered into the separation chamber. A stable feeding process ensures continuous airflow contact and reliable sorting performance.
Negative Pressure Airflow System :The fan generates controlled negative pressure to capture lightweight materials, maintain stable airflow conditions and reduce dust leakage during operation.
Separation Chamber :Inside the chamber, materials are classified by density, particle size and aerodynamic characteristics. Lightweight fractions are carried by airflow, while heavier materials move forward.
Discharge System :Separated fractions are discharged through independent outlets. Light materials such as plastic films, paper and RDF components are collected for further recycling or processing.
