Working Principle
Particle Interception
When contaminated air enters the filter, it passes through the filter media, where airborne particles are captured and retained by the filter fibers.
Multi-Stage Filtration
The filter media uses multiple filtration mechanisms to separate different types of airborne particles, allowing cleaner air to pass into the downstream air system.


Expanded Filtration Area
The bag-style structure provides a larger effective filtration area, helping improve the utilization of the filter media and overall dust-holding capacity.
Stable Airflow
The optimized filtration structure allows air to pass evenly through the filter media, helping maintain stable airflow during operation.
Product Advantages
Stable Filtration
The optimized bag-style filtration structure effectively captures dust and particulate matter while maintaining stable filtration performance.
Good Dust-Holding Capacity
The bag-style structure provides a large effective filtration area, allowing the filter to retain a considerable amount of captured particulate matter during operation.
Balanced Airflow Resistance
The filter media and bag structure are optimized to allow air to pass smoothly through the filtration media while maintaining effective filtration.
Easy Maintenance
The product is designed for convenient installation, removal, and replacement, making routine maintenance of ventilation systems easier.
Instructions for Use
Before installation, confirm that the filter specifications and installation direction are compatible with the equipment, and install the filter according to system requirements.
After installation, inspect the connection and sealing between the filter and equipment to help minimize air leakage or bypass.
During operation, keep the ventilation equipment running normally and avoid abnormal airflow conditions that could impact or damage the filter bags.
Inspect the filter according to the actual operating environment and replace it when the filter media becomes significantly contaminated or begins to affect system operation.
Follow the equipment operating requirements during installation, replacement, and maintenance, and use appropriate protective measures when necessary.
