Brief summary
A dust collector is an air pollution control system that filters and captures dust particles from industrial airflow before they are released into the environment or recirculated. This system maintains air quality in the workplace, protects workers’ health, and helps industries meet particulate emission standards.

How it works
How does a dust collector work?
01
Air intake
Dusty air is drawn in from the source through ducting.
02
Particle separation
Dust is separated using filters, centrifugal force, or electrical charge.
03
Media cleaning
Dust is released from the filter media and falls into the hopper.
04
Clean air comes out
Clean air is released, and the collected dust is disposed of periodically.
Product type
Types of dust collectors we manufacture
Selected based on particle size, dust volume, gas temperature, and the capture efficiency requirements for your specific application.
Cyclone separator (vacuum cyclone)
Uses centrifugal force to fling particles against the tube wall. Effective for coarse dust, simple construction, and low operating costs.
Fabric filter / baghouse
Filtering dust using fabric bags (filter bags). High efficiency for fine particles; classified based on the filter cleaning method.
Pulse jet
Cleaning with a pressurized air jet; can operate continuously without interrupting the flow.
Shaker
Mechanical vibration cleaning of bag filters; simple design and energy-efficient.
Reverse air
Cleaning with low-pressure reverse airflow, which is gentle on the filter media.
Cartridge collector
Uses a pleated cartridge filter that provides a large filtration surface area within a more compact unit.
Electrostatic precipitator (ESP)
Charges dust particles so they are attracted to the collection plate. High efficiency for very fine particles with low pressure drop.
Dry ESP
Dust is mechanically removed from the collection plates (by rapping) for dry gas streams.
Wet ESP (WESP)
Plate cleaning using a liquid, suitable for moist, sticky, or high-temperature gases.
Inertial separator
Separates particles by suddenly changing the flow direction to take advantage of the particles' inertia. Commonly used as a pre-cleaner before the main unit.
Unit / self-contained collector
Integrated compact unit (blower, filter, and dust collector in a single housing). Ideal for single-point applications or limited workspaces.

Frequently asked questions
All about dust collectors
What is the difference between a baghouse and a cartridge collector?
A baghouse uses long, cylindrical fabric bags, while a cartridge collector uses more compact pleated filters that provide a large filtration area within a smaller footprint.
What is the difference between a pulse jet, a shaker, and a reverse-air system?
These three are methods for cleaning filter bags: pulse jet uses a burst of pressurized air, shaker uses mechanical vibration, and reverse air uses a low-pressure reverse airflow.
When is it better to use an ESP rather than a baghouse?
ESP systems are generally chosen for large gas volumes containing very fine particles and requiring low pressure drop, while baghouse systems excel at filtering fine particles with a lower initial investment.
What is the difference between a dust collector and a wet scrubber?
A dust collector captures solid dust particles without using liquid, whereas a wet scrubber uses liquid to capture both gases and particles.
