What is the difference between H13 and H14 high efficiency filters?

2022-05-19 Page view : 710 views

The difference between H13 and H14 high efficiency filters is in the filtration efficiency:


H13 generally refers to 99.97%-99.99%

H14 generally refers to 99.995%-99.999%

Both are rare for 0.3um dust particles


The difference between high efficiency filters H13 and H14 is mainly the difference in efficiency, one is 99.99 and the other is 99.995, which is not much different, and can be directly replaced.


The high-efficiency filter is mainly used to capture particulate dust and various suspended solids below 0.5um, as the end filter of various filtration systems. The ultra-fine glass fiber paper is used as the filter material, and the plastic paper, aluminum foil board and other materials are folded as the dividing plate, sealed with a new type of polyurethane sealant, and the outer frame is made of galvanized sheet, stainless steel sheet and aluminum alloy profile.


Types of high efficiency filters:

High efficiency filters with partitions, high efficiency filters without partitions, combined high efficiency filters, tank type high efficiency filters, disposable integrated/replaceable integrated high efficiency filters, high humidity resistance and high efficiency Filter, high temperature resistant high efficiency filter (Hepa Box H10 H11 H12 H13 H14 manufacturer) Efficiency class: H10, H11, H12, H13, H14. Mainly for the filtration of particles above 0.3μm.


High-efficiency filter is an advanced and excellent filter equipment, which uses fiber as filter material. Since the diameter of the fiber can reach several microns, but at the same time its specific surface area is large, the resistance of filtration is greatly reduced and the efficiency of filtration is improved.


The components of the high-efficiency fiber filter include fiber bundle filter material, fixed porous plate, movable porous plate, and air distribution device.


High efficiency filter features:


1.) High filtration precision and good effect: the diameter of the fiber is small, the specific surface area is large, the gap between the filter materials is very small, and the filtration effect is good.

2.) Fast filtration speed: The filtration speed is 3 to 5 times that of the general traditional filter, and the filtration efficiency is high.

3.) Strong adjustability: The fiber density can be adjusted, and there is an adjustment device at the lower end of the filter device, so the filter precision, filter resistance and dirt interception capacity of the filter can be adjusted.

4.) Large dirt interception capacity: The dirt interception capacity is 2 to 4 times that of general conventional filters.

5.) Small footprint: The high-efficiency filter has a compact structure design and a small footprint.

6.) Low filtration cost: Use high-efficiency filters and ordinary filters to filter one ton of water, and the use cost of high-efficiency filters is lower than that of ordinary filters.

7.) Strong backwashing ability: The backwashing function can be realized by adjusting the fiber density of the high-efficiency filter, and the water consumption is still very low.

8.) Long service life: When the filter material is contaminated, we can clean it without having to replace it, and the general service life can be as long as 10 years.
