Performance characteristics of high efficiency filter without diaphragm of aluminum frame:

1. for ≥ 0.3 μ The filtration efficiency of M particles is over 99.9995%

2. spray folding with computer-controlled automatic folding machine system, and the folding height range can be adjusted steplessly between 22 and 96mm

3. special ultra fine glass fiber filter paper as filter material

4. Each filter is strictly tested

5. Adopt international standard size specification

6. F-type is knife mouth type, which is used for liquid tank sealing

7. it is mainly used in the electronic and pharmaceutical industries, dust-free room, laminar flow equipment and other occasions requiring ultra-high cleanliness

High efficiency filter without diaphragm is the most common filter in clean engineering. In most projects, the high efficiency filter with diaphragm has replaced the traditional filter with diaphragm. High quality filter materials, strict quality management, clean production environment, years of manufacturing experience, hinqi high efficiency filter without diaphragm can meet the high-grade requirements of clean engineering.

Configuration of air purification system in dust free workshop:

The dust-free workshop system is equipped with a set of three-stage air purification system, with coarse, medium and high efficiency filters to control the number of dust particles in the clean area. As the terminal filter high efficiency filter device determines the operation effect of the whole purification system, the installation of dust-free workshop is very important for the replacement time of high efficiency filter. In the decoration of the purification workshop, whether it is the high-efficiency air filter with large air volume installed at the end of the clean refrigeration unit or the high-efficiency air filter installed at the high-efficiency air supply outlet, this kind of high-efficiency air filter must have accurate operation time record, cleanliness grade and exhaust air volume as the basis for removal and replacement. Under the normal application condition, the service life of the high-efficiency filter can be nearly one year. If the service life of the HEPA filter with good front-end protection can reach more than two years, of course, it also depends on the quality of the HEPA filter, such as the HEPA filter installed in the purification equipment, such as the HEPA filter in the automatic air shower room, if the front-end protection is good, the service life can reach more than three years.

The air purification system configuration of dust-free workshop has the following requirements for workshop decoration:

1、 The materials with good air tightness and small deformation under the influence of temperature and humidity changes should be selected for the building envelope wall and interior decoration of industrial purification workshop. The wall and hanging surface of the purification workshop shall be smooth, smooth and free from cracks, and the joints shall be tight and free from defects.

2、 The enclosure wall and interior decoration of industrial purification workshop should be selected with good air tightness and small deformation under the effect of temperature and humidity changes.

3、 The surface of the walls and ceiling of the purification workshop shall be smooth, smooth and free from cracks, the interface shall be tight, no particles shall fall off, and shall be resistant to cleaning and acid. The joint of wall, floor and ceiling shall be made into arc, and the skirting board shall not be higher than the wall. When using light materials to melt and crush, anti-collision measures should be taken.

4、 The ground of purification workshop should be integral, flat, wear-resistant, impact resistant, not easy to accumulate static electricity, easy to dust and clean. The ground cushion should be strengthened, and damp proof treatment should be carried out in humid areas.

5、 When the mezzanine is light ceiling, the maintenance channel shall be set. The internal surface decoration standard of clean air duct and return air duct shall be applicable to the whole return air system and easy to remove dust.
