High Capacity Bag Filter For HVAC Systems
Bag air filters are dry and highly efficient filtration devices that use fluffy fiber filter bags as core filtration elements. Their working principle is that when dusty air passes through the filter bags, dust particles are captured in the filter bag fibers due to effects such as inertial collision and interception diffusion, thereby achieving gas-solid separation.
Its main advantages lie in its large air handling capacity, low initial pressure drop and significantly higher dust holding capacity than ordinary filters. This means that it can maintain high-efficiency filtration for a long time during the process of slow resistance increase, thereby effectively extending the service life and reducing maintenance frequency and operating costs.

Product Description
Bag-type air filters capture particles in the air through multiple fluffy fiber filter bags inside. This design is like a deep dust trap, which can firmly trap dust deep in the fibers while the airflow flows smoothly. It not only achieves efficient filtration under high air volume, but also significantly extends its own lifespan due to its excellent "dust storage" capacity. Therefore, it has become a favored and long-lasting guardian in the ventilation systems of commercial buildings and industrial plants.

Product features



1. High dust holding capacity and long service life: Due to its unique bag structure, it provides a huge effective filtration area, which can accommodate more dust, thereby significantly extending the service life and reducing the frequency of replacement.
2. Low initial resistance, energy conservation and environmental protection: The fluffy filter bag structure and large filtration area ensure smooth air flow, with low initial pressure loss, which helps to reduce the energy consumption of the fan and lower operating costs.
3. Stable filtration efficiency: Before reaching the dust-holding limit, the filtration efficiency can be maintained at a relatively stable high level to ensure continuous purification effect.
4. Robust structure and strong applicability: The outer frame is usually made of metal or reinforced plastic, and the filter bags are available in glass fiber and synthetic fiber materials, which can adapt to different temperature and humidity environments and air volume requirements.
5. Good economy: Considering its long service life, low energy consumption and relatively low maintenance requirements, bag filters have a very high cost performance.
Product Applications
1. Commercial and public buildings: Widely used in the pre-filtration or intermediate filtration of central air conditioning and fresh air systems in office buildings, shopping malls, hotels, hospitals, and schools to protect indoor air quality and subsequent equipment.
2. Industrial manufacturing: It is used in clean workshops and ventilation systems in industries such as electronics, semiconductors, precision instruments, spraying, food processing, and pharmaceuticals, serving as a medium-efficiency filtration section to remove dust particles that are harmful to the production process.
3. Industrial dust removal: As the terminal or pre-filtering unit of some industrial dust removal systems, it is used to collect larger particles of dust and protect the highly efficient main dust collector.
4. Other places: Ventilation systems in public places such as museums, libraries, and stadiums that have requirements for air cleanliness.
