Air Filter Solution

Air filter mainly includes primary efficiency filter, medium efficiency filter and HEPA filter.

(1) Primary efficiency filter

There are four styles of plate, folding, bag and box, the outer frame materials are paper frame, aluminum frame, galvanized iron frame, stainless steel frame, filter materials are non-woven fabric, nylon net, activated carbon filter cotton, metal hole mesh, etc., the protective net has double-sided spray plastic wire mesh and double-sided galvanized wire mesh. Low price, light weight, good versatility, compact structure.

Primary efficiency filter use:

The primary efficiency filter is suitable for central air conditioning and central ventilation system filtration; Large air compressor filtration; Clean return air system; Pre-filtration of HEPA filter device.

Primary efficiency filter features:

1. the outer frame is made of solid plate aluminum alloy frame, and the air outlet surface is added with diamond protection net to ensure that the filter will not be deformed or damaged in poor working environment; Light plate structure.

2. the filter material is made of high quality polyester synthetic fiber, can be cleaned and reused many times, long service life, economic and practical, fluffy and dense fiber structure, to ensure a high dust collection rate and a large dust capacity, effectively extend the service life of the medium effect filter at the back end.

3. 1 inch (21mm, 25mm) different thickness options, optional filter grade: G1, G2, G3, G4(EN779)

2) Medium efficiency filter is widely used for intermediate filtration of air conditioning system, suitable for occasions with high dust concentration, the use of high-quality chemical fiber non-woven filter material, large dust capacity. It is mainly used for filtering 1-5μm dust particles, with the advantages of low resistance and large air volume. Medium efficiency filter has bag type and frame type, combined type and so on.

Bag type medium efficiency filter is made of ultrafine synthetic fiber by special weaving method to avoid the discomfort caused by old glass fiber materials, the filter material contains electrostatic fiber, the filtration efficiency of sub-micron (less than 1 or less than 1micron) dust is particularly good, the filtration efficiency of 1micron particles is 85%, with high dust trapping power, high dust load and high permeability. High service life.

Medium efficiency filter features:

Efficiency: F5-F9 (colorimetric);

Features: The filter material is made of extremely fine glass fiber;

Application: Widely used in pharmaceutical, electronic, food industry and general air conditioning system.

Note: Handle with care when handling, install vertically.

(3) HEPA filters are mainly used to capture particulate dust and various suspended matter below 0.5um. Ultrafine glass fiber paper is used as filter material, offset paper, aluminum film and other materials as partition plate, and the wood frame aluminum alloy is glued. Each unit has been tested by the flame method, and has the characteristics of high filtration efficiency, low resistance and large dust capacity. HEPA filter can be widely used in optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverages and food, PCB printing and other industries clean air conditioning end supply. High efficiency and ultra-high efficiency filters are used at the end of the clean room, and can be divided into: high efficiency with partitions, high efficiency without partitions, high air volume, ultra-high efficiency filters and so on.

Application range of HEPA filter:

It is mainly the end filtration of pharmaceutical, civil or industrial clean places with high cleanliness requirements in electronics, semiconductors, precision machinery, pharmaceuticals, hospitals, food and other industries. Since the high efficiency filter is generally used as the filter end, the requirements for the high efficiency filter are also the most stringent.

The high efficiency filter with separator is made of ultrafine glass fiber paper as filter material, and plywood paper as separator. Both can be combined with aluminum alloy frame, wood frame and galvanized steel plate frame.

With a diaphragm HEPA filter characteristics: with low resistance and high efficiency, light weight, large dust capacity and other characteristics.

Suitable for ambient air purification under normal temperature, pressure and humidity conditions;

Especially suitable for clean buildings requiring high coverage of HEPA filters.

HEPA filter without partition Features:

Uses: Installation forms of clean room end air supply port, FFU, clean equipment, etc., are widely used in electronics, semiconductor, pharmaceutical, food and other industries

 

To extend the service life of the HEPA filter, the most fundamental and simplest way is to keep the dust out of the primary efficiency filter. In other words, ensure that the air flow exposed to the HEPA filter is the air filtered after the primary efficiency filter and the medium efficiency filter. At this time, the air should reach the standard of 99.95% small dust particles and low pollution.
