Working Principle

The LB-JZX welding dust purifier operates on a well-engineered multi-stage filtration principle:

Stage 1 – Smoke Capture: Welding smoke and exhaust gases are drawn into the purifier through the universal suction 

hood and arm by the suction force generated by the fan. The flexible arm allows precise positioning directly at the fume 

source for maximum capture efficiency.

Stage 2 – Spark Arrest: The incoming air first passes through a flame arrester (fire retardant net), which blocks and 

extinguishes sparks and hot particles, preventing fire hazards within the filter chamber.

Stage 3 – Settling Chamber: The smoke enters the settling chamber, where gravity and the upward airflow cause coarse 

dust particles to drop directly into the ash hopper, reducing the load on the filter element.

Stage 4 – Filtration: Fine particulate dust is captured on the outer surface of the high-efficiency filter element. 

Cleaned gas passes through the filter media and enters the center of the filter element.

Stage 5 – Clean Air Discharge: The purified air flows from the filter element center into the clean air plenum and is discharged

 through the outlet, meeting environmental emission standards.

Stage 6 – Automatic Cleaning: The pulse blowback system periodically directs compressed air through the filter element

 in reverse direction, dislodging accumulated dust for collection in the ash drawer.

Equipment Advantages

(1) High-Quality Motor with Protection

Equipped with a specialized turbine and Siemens brand motor, the purifier features an anti-overload circuit that prevents

 motor burnout. This ensures high safety and stable performance even during extended operation.

(2) Pulse Blowback Automatic Cleaning

The filter element employs an automatic rotating pulse blowback cleaning system that thoroughly removes dust from

 the filter surface, maintaining constant suction volume. The air compressor connection uses a high-pressure hose, 

and the bottom high-pressure air intake ensures the purifier remains in optimal operating condition. The system can 

be configured for automatic or manual control based on user requirements.

(3) Advanced PTFE Polyester-Coated Filter Media

The filter cylinder utilizes PTFE polyester-coated filter paper with a long service life. This advanced media captures dust 

particles down to 0.3 μm, ensuring superior air quality.

(4) 360-Degree Flexible Suction Arm

The universal suction arm allows 360-degree movement, enabling operators to position the suction hood precisely at 

the smoke source. This targeted extraction significantly improves dust collection rates and ensures operator health protection.

(5) Triple Fire Protection Measures

Three separate protective measures guard against fire hazards and large particle slag ingress, extending the purifier's

 service life and ensuring safer, more reliable operation.

(6) Low Noise Design

Clean air is evenly guided and dispersed through a grid-like vent design, reducing operational noise to within acceptable 

standards for the working environment.

(7) Easy Mobility and Positioning

Heavy-duty Korean-style casters with brakes allow for convenient equipment movement and secure positioning, enabling 

the purifier to be deployed exactly where needed.
