Particulate Air (Hepa) Filter Without Separator

The high-efficiency particulate air (HEPA) filter without separator adopts separator-free materials as the filter element replacing the aluminum and paper separators used in traditional HEPA filters with separators. Its filter element is typically made of separator-free materials such as glass fiber and PP filter paper offering higher filtration efficiency and a longer service life. Additionally the separator-free design makes the entire filter structure more compact and lightweight which helps reduce air resistance and enhance air permeability.

Performance Characteristics
High-efficiency filtration: HEPA filters without separators have a filtration efficiency of over 99.97% for particles a Y0.3I m and some products can even achieve higher filtration levels (such as H14 U16 etc.) effectively intercepting fine particulate matter microorganisms and gaseous pollutants in the air.
Low resistance: Due to their compact structure and high-efficiency filter materials HEPA filters without separators generate relatively low resistance during operation which is beneficial for energy saving.
Long service life: The use of advanced filter materials and manufacturing processes results in a longer service life for HEPA filters without separators reducing the frequency of replacement and maintenance costs.
Temperature and humidity resistance: Some HEPA filters without separators exhibit good temperature and humidity resistance maintaining stable filtration performance within a wide range of temperatures and humidity levels.

Working Principle
The working principle of HEPA filters without separators mainly relies on their unique separator-free structure and fine fiber filter media. When air passes through the filter it first goes through a pre-filter that retains larger particles and then further undergoes detailed filtration through the HEPA filter without separators. The fine fiber filter media can form a large number of micro-pores increasing the filtration area and efficiency. At the same time some materials have electrostatic effects that can alter the trajectory of dust particles enhancing the purification effect. Under the action of gravity the dust particles lose their weight and settle on the fiber surface achieving the desired purification effect.

Application Areas
HEPA filters without separators are widely used in various fields such as medicine food electronics and precision instrument manufacturing providing clean production environments for these industries and ensuring product quality and people's health. For example in the pharmaceutical field HEPA filters without separators are used in the air purification systems of drug production workshops to ensure the cleanliness of the production environment; in the food field they can effectively prevent food from being contaminated by dust and bacteria in the air; in the electronics and precision instrument manufacturing fields they can ensure the cleanliness of the production environment and avoid damage to products and equipment caused by dust and microorganisms.
