What is the working principle of the partitionless high-efficiency filter?

1. Structure

The partitionless high-efficiency filter is a high-efficiency filter commonly used in air purification systems. It improves the filtration efficiency and air flow through a specially designed partitionless structure. Traditional filters generally adopt a partition structure, which consists of a series of parallel metal or plastic partitions. When air passes through the filter, it collides with the partition, resulting in a curved and rotating flow path, which causes the dispersion and turbulence of the streamline. This turbulent phenomenon will cause the suspension and sedimentation of particulate matter, affecting the filtration effect. The partitionless high-efficiency filter adopts a special structural design, cancels the partition in the traditional filter, makes the air flow smoother, and reduces the generation of turbulence. Its structure generally consists of two layers of wire mesh and the filter material in the middle. The function of the wire mesh is to support the filter material to prevent the filter material from being adsorbed and blocked, and it also simplifies the flow path and reduces turbulence;

2. Filter material

The filter material is the key part of the non-partitioned high-efficiency filter, which is usually made of fine fiber materials such as glass fiber and synthetic fiber. These fine fibers can form a large number of fine pores, thereby increasing the filtration area and filtration efficiency. When the particles in the air pass through the filter material, they will be trapped on the surface or inside of the filter material, thereby achieving the filtering effect;

3. Static electricity

Some materials of the filter have static electricity, which can change the movement trajectory of dust particles so that they collide with obstacles and finally achieve the purification effect;

4. Gravity effect

Under the action of gravity, the dust loses weight, breaks away from the original movement displacement, and falls on the fiber surface. This is the gravity effect, which makes the filter filter and achieve the ideal purification effect.

As can be seen from the above, the non-partitioned high-efficiency filter improves the filtration efficiency and air flow by eliminating the partition structure in the traditional filter and adopting a specially designed non-partitioned structure, fine fiber filter material, static electricity and gravity effect, becoming an indispensable and important part of the air purification system. In addition to producing partition-free HEPA filters, Bailun Purification also produces various large-volume HEPA filters, liquid tank HEPA filters, partition-equipped HEPA filters, etc. that use advanced filter element materials. They are widely used in hospitals, laboratories, electronics factories, and other places that require high-quality air, effectively ensuring the health and safety of staff.
