Dust Collector Purification Principle

In a high negative pressure dust collector, dust-laden air is drawn through the duct via the inlet into the filter cartridge chamber under fan suction. Large, heavy particles settle into the ash collection hopper, while fine particles are retained on the outer surface of the filter cartridge as the airflow passes through. Clean air enters the clean air plenum and is discharged through the fan exhaust.
When the pressure differential across the filter cartridge reaches the set value, the pulse solenoid valve opens, instantly cleaning the cartridge with a pulse-jet of compressed air without interrupting operation. After cleaning, the pressure differential decreases, and the unit resumes normal working condition.

Product Features

- High-vacuum dust collector specifically engineered for flammable and explosive dust applications.
- Equipped with explosion vent for automatic pressure relief; independent explosion-proof electrical enclosure ensures safe operation.
- Automatic pulse control system cleans filter cartridges via differential pressure or timer-based online reverse blowing, minimizing downtime and maintenance intervals.
- Temperature monitoring with automatic alarm and shutdown on abnormal readings, reducing fire hazards.
- End-cap locking mechanism provides excellent sealing, enables quick disassembly, and simplifies filter cartridge replacement.
- Horizontally mounted filter cartridges maximize filtration area and decrease replacement frequency.
- Ergonomic human-centered design for enhanced operational convenience.
- Compact footprint ideal for indoor installation, saving both shipping costs and floor space.
- Inlet baffle buffers airflow velocity to protect filter cartridges and prevents dust rebound during shutdown pulses.
- Fitted with Foma casters for easy mobility and leveling.
