The LFVB-type dust collector integrates mechanical rotation, micro-shock vibration, and reverse-air cleaning into a single, advanced filtration system. Featuring flat filter bags arranged radially in a cylindrical form, this design improves filtering efficiency and extends bag life compared to traditional systems.
🛠 Key Features & Advantages
Dual-stage Filtration
Pre-separation: Incoming dusty air enters through a tangential inlet and swirls inside a cyclone chamber—larger particles fall into the hopper first.
Fine filtration: Remaining dust is captured by flat bags, ensuring deeper cleaning.
Mechanical Rotary Reverse‑Blow Cleaning
A reversing fan sends clean air through the rotating arm across individual bag rows.
Each row receives localized reverse airflow and vibration, dislodging dust without halting system operation.
Enhanced Noise Control & Longevity
The buffer chamber smooths airflow before filtration, reducing noise and minimizing mechanical abrasion on the bags.
Independent Reverse-Flow System
Reverse air cleaning uses its own fan rather than compressed air, improving reliability and eliminating contamination from condensate.
High Bag Density, Compact Footprint
Flat, trapezoidal bags are tightly packed in a circular array, allowing more media area in less space and efficient dust removal.
Automated & Continuous Operation
PLC control sequences the rotation and cleaning of bag rows, enabling continuous dust collection without manual interruption.
