There are several types of industrial dust collectors or vacuum cleaners designed for pneumatic transport systems in various industries:

Baghouse Filters: Utilize fabric bags or cartridge filters to capture dust particles. They are effective for applications where large volumes of air with fine particles are handled.

Cyclone Separators: Operate using centrifugal force to separate dust particles from the airflow. They are effective for larger particles and in applications where frequent cleaning is required.

Electrostatic Precipitators: Use electric fields to charge dust particles, which are then collected on plates or tubes. They are effective for very fine particles and applications requiring high collection efficiency.

Cartridge Collectors: Employ filter cartridges to capture dust particles. They are compact and effective for applications requiring reduced size and easy maintainability.

Drum Collectors: Use rotating drums to collect dust, separating it from the airflow through gravity action. They are useful for coarser particles and in applications needing continuous operation.

Wet Scrubbers: Use water or liquids to capture and neutralize dust particles. They are effective for sticky materials or controlling gas emissions.

Each type of industrial dust collector or vacuum cleaner has its own advantages and is selected based on specific collection needs, the type of material handled, and the environmental and operational conditions of the industrial process.
