Separated HEPA filter

What is a Separated HEPA filter?

Separated HEPA filter is a kind of air filter, which is mainly used for terminal filtration of various levels of clean rooms and various local purification equipment, such as clean workbench laminar flow hood and other environmental air purification.It uses superfine glass fiber filter material, laser scanning test one by one, high temperature resistance up to 80 ℃, low resistance, high efficiency, long service life.

What type of material is typically used as a divider

The main partition materials of high efficiency filter are glass fiber, chemical fiber or polytetrafluoroethylene fiber.For mini pleat air filter, superfine glass fiber is usually used as the filter material and hot melt adhesive as the separator of the filter element.A high efficiency filt with a partition uses aluminum foil or pap as a partition.In addition, some manufacturers use electrostatically charged polytetrafluoroethylene fiber (electret) to make high efficiency filters.The choice of these materials mainly depends on their filtration efficiency, high temperature resistance and environmental protection.

What type of equipment or place is it mainly used in?

High efficiency filters are widely used to improve air quality and remove airborne particles such as dust, bacteria and viruses.It is widely used in medical treatment, clean room, public places and home environment.Specifically, the high-efficiency filter can be widely used at the air supply end of the air conditioner in the dust-free purification workshop of the industries such as optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverage and food, PCB printing and the like.In addition, high efficiency and ultra-high efficiency filters are used at the end of the clean room, which can be divided into high efficiency filter with clapboard, mini pleat air filter, high air volume high efficiency filter, ultra-high efficiency filter and so on.Among them, the ultra-high efficiency filter has the highest filtration efficiency, which can reach 99.9995%, providing a healthy and safe air environment for people's production and life.

The channels formed by the high efficiency filter with aluminum baffles or paper baffles have the advantage of creating laminar air flow

Aluminum separator and paper separator HEPA filters have some advantages in creating laminar air flow.

These filters are made of aluminum foil, paper and other materials into a folded shape as a filter element separator to form an air channel.This structure helps to maintain a smooth air passage, thereby improving the filtering efficiency.

Aluminum clapboard filters are mainly used in high temperature or high humidity environments, while paper clapboard filters are suitable for ordinary clean environments.The air volume of the filter with the clapboard is relatively large, the efficiency can reach high efficiency, and the filter with the clapboard can be used for high temperature filtration.

However, it should be noted that when the temperature and humidity change, the paper partition may emit large particles, which may affect the cleanliness test results of the clean plant.Therefore, for locations with higher cleanliness requirements, HEPA filters without baffles may be preferred.

In general, HEPA filters with aluminum separators and paper separators can effectively improve filtration efficiency by forming stable air channels, especially under specific environmental conditions.However, when choosing, it is necessary to determine the most suitable filter type according to the specific application environment and cleanliness requirements.

Cost comparison and application effect comparison of aluminum separator and paper separator

There are some differences in cost and use effect between aluminum separator and paper separator high efficiency filters.Aluminum baffle filters are generally more expensive because of their adaptability to high temperatures or high humidity.However, its air volume is relatively large, its efficiency can reach high efficiency, and it can be used for high temperature filtration.

In contrast, paper baffle filters are primarily used in general clean environments and are therefore relatively inexpensive to manufacture.However, it should be noted that when the temperature and humidity change, the paper partition may emit large particles, which may affect the cleanliness test results of the clean plant.

Compared with mini pleat air filter, although its price is relatively higher, it has the advantages of small size, light weight, compact structure, reliable performance, easy installation, stable efficiency and uniform wind speed.Mini pleat air filter is preferred especially in demanding unidirectional flow and high grade non-unidirectional flow cleanroom projects.

Generally speaking, which type of filter to choose should be decided according to the actual needs and application scenarios, and the balance between cost and benefit should also be considered.

What is the main difference between Separated HEPA filter and minipleat HEPA filters?

The main differences between the mini pleat air filter and the HEPA filter are their structure and performance characteristics.

First of all, from the structural point of view, the mini pleat air filter uses hot melt adhesive as the partition, the outer frame is beautiful, and it has the characteristics of small size, light weight and compact structure.

The separated HEPA filter uses gummed paper and aluminum foil as the partition, which is mixed with wood frame or aluminum alloy frame glue. This design makes it have the advantages of high filtration efficiency, low resistance and large air volume.

Secondly, in terms of filtration materials, glass fibers are mostly used in mini pleat air filter, chemical fibers are gradually used, and some manufacturers also use electrostatically charged PTFE fibers (electret) to manufacture high-efficiency filters.In contrast, a separator HEPA filter typically uses glass fiber paper as the filter material.

In addition, mini pleat air filter and high efficiency filters with baffles differ in the treatment of air streams.Baffle-free filters provide a higher air flow with less resistance due to the lack of baffles.Although the air volume of the filter with clapboard is large, it may cause greater resistance.

Generally speaking, mini pleat air filter and high efficiency filter with partition have their own advantages, and the choice of which type of filter depends on the actual needs and application scenarios.
