Aluminum partition high-efficiency filter

Aluminum partition high-efficiency filters are widely used filtration devices in air purification systems. The following will introduce them from aspects such as their structural composition, working principle, features, and application fields:
Structural composition
Filter material: Usually, superfine glass fiber filter paper is adopted, which has an extremely high filtration efficiency and can effectively capture tiny particles in the air, such as dust particles of 0.3 microns and below.
Aluminum separator: The corrugated aluminum separator is a key component of this filter. Its function is to precisely maintain the pleat spacing, making it easy for the airflow to pass through, maximizing the utilization of the filter material with the least resistance, and at the same time increasing the strength of the filter.
The outer frame: Common outer frame materials include aluminum, galvanized steel, and stainless steel, among others. It features sturdiness, durability, and corrosion resistance, which can protect the internal filter material and partition while also facilitating the installation and fixation of the filter.
Sealant: A specially formulated high-temperature resistant sealant is used to seal all components of the filter to prevent air leakage and ensure the filtration effect. According to different usage requirements, sealants of different temperature resistance grades can be selected. For instance, silicone rubber strips can withstand temperatures up to 250℃, and polytetrafluoroethylene strips can endure temperatures ranging from 350 to 400℃.
Working principle: When air passes through the aluminum diaphragm high-efficiency filter, it first enters the aluminum diaphragm high-efficiency filter after being roughly filtered by the primary filter. Then, on the exhaust side, the air is further filtered by the pleated paper sheets, high-efficiency filter screens, and other materials distributed throughout the aluminum diaphragm. Due to the 180° folding on both sides of the filter material to form wedge-shaped pleats, and the fact that there are two indentations when the filter material is bent, a wedge-shaped box-shaped pleat is opened at the tail end of the partition, which intercepts and adsorbs the tiny particles in the air onto the filter paper, thus completely filtering out the particles with a diameter of more than 0.3 microns in the air, ensuring the cleanliness of the indoor air.
Product features
High filtration efficiency: At the rated air speed, the filtration efficiency for particles as small as 0.3 microns can reach over 99.99%, effectively removing bacteria, viruses, dust, and other pollutants in the air, providing high-quality clean air.
Large effective filtration area: The pleated V-shaped filter material structure and the design of aluminum partitions enable the filter to have a large effective filtration area in a smaller volume, increasing the dust holding capacity and extending the service life of the filter.
Low resistance: The corrugated aluminum partition precisely maintains the pleat spacing, ensuring smooth air flow with low resistance, thereby reducing the energy consumption of the air conditioning and ventilation system.
Good high-temperature resistance: Some models of aluminum partition high-efficiency filters can withstand temperatures above 250℃ or even 350℃, making them suitable for applications with high-temperature environmental requirements.
Adapt to high humidity environments: Utilizing ultra-fine glass fiber filter paper resistant to high humidity and special sealant, it can operate normally in high-humidity conditions without affecting its filtration performance due to moisture.
Application field
Electronic semiconductor industry: Used in clean rooms for chip manufacturing, semiconductor packaging, etc., to prevent tiny particles from contaminating electronic components and ensure product quality.
Pharmaceutical industry: In places such as drug production workshops and laboratories, ensure the cleanliness of the air, prevent drugs from being contaminated, and meet the requirements of Good Manufacturing Practice (GMP) for drugs.
Food processing industry: It is used in food production workshops, packaging workshops, etc., to filter dust, bacteria, and other substances in the air, ensuring the hygiene and safety of food.
Hospitals: In areas such as operating rooms, intensive care units, and laboratories, provide clean air environments to reduce the risk of infection and ensure the health of patients and medical staff.
Other fields: It can also be applied to industries with high requirements for air cleanliness, such as aerospace, precision machinery manufacturing, optical instrument manufacturing, and cosmetics production, as well as air conditioning and ventilation systems in some high-end office buildings, shopping malls, hotels, and other public places to improve indoor air quality.
