Features and Advantages

1. High-efficiency purification

Employs a high-efficiency filter element to capture submicron-sized particles, resulting in high purification efficiency.

2. Source treatment

Collects pollutants directly from their source, preventing their spread within the workshop.

3. Health protection

Effectively protects employees' respiratory systems, preventing occupational diseases.

4. Quality improvement

Reduces the interference of fumes on the production environment and precision processes, improving product quality.

5. Energy saving and environmental protection

Purified air can be circulated indoors, reducing heat loss in the workshop during winter and lowering energy consumption.
