Bag Type Primary Filter

1. What is a Bag Type Primary Filter used for?

A Bag Type Primary Filter is primarily used in HVAC systems, air conditioning systems, and industrial ventilation to capture large particles such as dust, debris, and other contaminants from the air. It serves as the first stage of filtration, ensuring that only cleaner air moves further into the system. These filters are highly effective for applications requiring a higher dust-holding capacity.

2. How does a Bag Type Primary Filter work?

The Bag Type Primary Filter works by trapping particles in its fabric media. The filter material, often made from synthetic fibers or fiberglass, creates a dense filtration surface. Airflow passes through the fabric, and larger particles become trapped in the fibers, preventing them from circulating through the system. This method ensures that only cleaner air moves on to the next stages of filtration.

3. What are the benefits of using a Bag Type Primary Filter in HVAC systems?

Using a Bag Type Primary Filter in HVAC systems offers several advantages. These filters are known for their high dust-holding capacity, which leads to longer service life compared to standard filters. Additionally, they have low initial resistance, meaning they don't require significant energy to operate. This results in better airflow efficiency and cost savings over time.

Key Benefits:

• High dust-holding capacity

• Long service life

• Low initial resistance for efficient airflow

• Cost-effective for long-term use

4. How do I choose the right Bag Type Primary Filter for my system?

When choosing a Bag Type Primary Filter, consider factors such as the required filtration efficiency, airflow capacity, and the specific needs of your environment. Ensure the filter's material is suitable for the types of particles you wish to filter, and check its dimensions to match your system's specifications. The filter's resistance to airflow should also be considered to avoid unnecessary strain on the system.

5. What is the efficiency of a Bag Type Primary Filter?

The efficiency of a Bag Type Primary Filter typically ranges between 50% to 90%, depending on the particle size. These filters are designed to capture particles as small as 5.0μm and larger. The specific efficiency may vary based on the filter's design and material, with higher efficiencies being better suited for environments requiring stricter air quality control.

6. How often should a Bag Type Primary Filter be replaced?

A Bag Type Primary Filter should generally be replaced every 6 to 12 months, depending on the environmental conditions and the level of contamination in the air. In more polluted environments, filters may need to be changed more frequently. Regular inspection of the filter’s condition can help determine when it’s time for a replacement.

7. What materials are used in Bag Type Primary Filters?

Bag Type Primary Filters are commonly made from synthetic fibers, fiberglass, or a combination of these materials. The fabric construction provides durability and enhances the filter's dust-holding capacity. The choice of material depends on the specific application, such as the type of particles being filtered and the environment's conditions.

8. Can a Bag Type Primary Filter be used in cleanroom environments?

Yes, Bag Type Primary Filters can be used in cleanroom environments. They are often employed as the first stage of filtration in cleanrooms to remove larger particles from the air before it passes through more stringent HEPA or ULPA filters. These filters help maintain air quality by reducing the load on higher-efficiency filters, improving the overall system's lifespan and performance.

9. What is the typical airflow capacity for Bag Type Primary Filters?

The typical airflow capacity for Bag Type Primary Filters can range from 500 m³/h to 5000 m³/h, depending on the specific model and size. This range allows these filters to be used in various applications, from small residential systems to large industrial air handling units. The airflow capacity will vary based on the filter's dimensions and design.

10. How does a Bag Type Primary Filter compare to other types of air filters?

Bag Type Primary Filters generally offer better dust-holding capacity and longer service life compared to panel filters. While panel filters might be more common for general filtration, bag filters are preferred in situations requiring higher dust collection and extended filter life. However, they can have higher initial resistance, which may affect system performance if not properly matched.

Bag Type Primary Filter Product characteristics

The design of the bag type primary effect filter has significant features, mainly including:

• High-quality materials: the filter is made of synthetic fibers with gradually increasing density and strong toughness, which can withstand high wind pressure without air leakage or rupture, ensuring long-term stable filtration effect.

• Seamless fusion bonding technology: Through seamless fusion bonding technology, this filter has good airtightness and bonding strength, which reduces the possibility of air leakage and thus improves the overall filtration efficiency.

• Unique support design: The unique support design inside the bag keeps the filter stable and prevents it from collapsing when airflow passes through, ensuring the best filtration effect.

• Environmentally friendly characteristics: The filter material does not contain silicone, which is especially suitable for use in clean environments with high requirements for air quality, effectively avoiding contamination of the product.

Bag Type Primary Filter Filtration performance

Bag type primary effect filter has superior performance in filtration performance, which is mainly reflected in the following aspects:

• High-efficiency dust removal: the filter can effectively remove fine dust of ≥5.0μm particles, with a filtration efficiency between 40% and 60%, and also capture microorganisms, which greatly improves the cleanliness of the air.

• Low pressure drop design: Due to its excellent design, the bag primary filter maintains a low pressure drop during the filtration process, which not only helps to improve the operating efficiency of the fan, but also reduces energy consumption.

• Washability: The filter supports cleaning and has a long service life, which reduces the replacement frequency and maintenance cost, and has high economy.

• Diversified options: According to different air volume requirements, bag-type primary filters provide a variety of bag configurations to flexibly meet the requirements of different usage scenarios.
