Applications

Suitable for being used in commercial & industrial areas or hospitals, schools, public buildings. Also being applied in air conditioning plants, gas turbine equipment and cleanroom, etc.

M5, M6, F7 and F8 are all air filter classes defined in the European Standard EN 779, which are used to describe the efficiency of a filter in filtering airborne particles. Here are the main differences between them:

M5 class:
M5 grade filters are mainly used for filtering larger particles such as large dust, dirt and hair.
Suitable for applications where filtration of larger particle size pollutants is required, but less effective in filtering small particles.

M6 class:
The F6 grade filter provides higher filtration performance than the M5, effectively filtering medium-sized particles, including dust and pollen.
It is suitable for scenes with high air quality requirements, such as offices, commercial buildings, and so on.

F7 class:
The F7 grade filter further improves filtration efficiency by effectively filtering smaller particles, including fine dust, pollen and bacteria.
Suitable for scenes with high cleanliness requirements, such as medical institutions and laboratories.

F8 class:
The F8 level filter improves on the F7 by filtering even smaller particles, including finer dust, bacteria and smoke.
Ideal for applications requiring extremely high levels of cleanliness and air quality, such as highly sensitive manufacturing environments, laboratories, etc.
From M5 to F8, the grades represent a gradual improvement in the filter’s effectiveness in filtering airborne particles. When selecting a bag filter, it is important to choose the right grade of filter for the specific application to ensure that the desired air purification is achieved.

Benefits

1. Efficient Filtering Performance:
Bag-type air filters are typically multi-layered in design, with a large filtration surface area and highly efficient filtration materials. This design effectively captures microscopic air pollutants such as dust, pollen, bacteria and other microorganisms, providing superior air purification. Compared to some other filters, the structure of the bag filter is more conducive to capturing and immobilizing particles.

2. Long Service Life:
Because of their multi-layered structure and design features, bag-type air filters typically have a long service life. This means users don’t need to replace filters as often, saving on replacement costs and maintenance time. This also helps to ensure consistent performance of the air cleaning equipment over time.

3. Reduce Wind Resistance, Energy Saving and Environmental Protection:
Bag filters typically have a low wind resistance while capturing air pollutants. This low wind resistance helps to reduce the energy consumption of air purification equipment, making it more energy efficient and environmentally friendly. At the same time, the structure of the bag filter also helps to minimize the resistance to air flow, improving the overall efficiency of the system.

4. Easy to Replace:
Changing a bag-type air filter is usually a simple and easy task to perform. This makes it easy for the user to change the filter on their own, without the need for professional assistance. This simple and easy replacement process helps to ensure that the filter is always in optimal condition, providing consistent air purification.
