Difference between H 13 and H 14 high efficiency filters.

The difference between high-efficiency filters H 13 and H 14 lies in the filtration efficiency:

H 13 generally refers to 99.97%-99.99%;

H 14 generally refers to 99.995%-99.999%;

Both of them are precious to 0.3um dust particles;

The difference between H 13 and H 14 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.

High-efficiency filter is mainly used to collect particulate dust and various suspended substances below 0.5um, which is used as the end filtration of various filtration systems. Ultrafine glass fiber paper is used as filter material, offset paper, aluminum foil and other materials are folded into partition board, sealed with new polyurethane sealant, and galvanized sheet, stainless steel sheet and aluminum alloy profile are used as outer frame.

Types of high-efficiency filters: clapboard high-efficiency filter, non-clapboard high-efficiency filter, combined high-efficiency filter, tank high-efficiency filter, disposable integrated/replaceable integrated high-efficiency filter, high-humidity resistant high-efficiency filter and high-temperature resistant high-efficiency filter. Efficiency grades: H 10, h1,H 12, H 13, H 14. Mainly for particles above 0.3μm filtration.

Extended data:

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

The high-efficiency fiber filter is composed of fiber bundle filter material, fixed perforated plate, movable perforated plate and gas distribution device.

Features of high efficiency filter:

1. The filtration precision is high, and the effect is good: the fiber diameter is very small, the specific surface area is large, the gap between 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 general traditional filters, and the filtration efficiency is high.

3. Strong adjustability: the fiber density can be adjusted, and there is an adjusting device at the lower end of the filtering device, so the filtering accuracy, filtering resistance and pollution interception ability of the filter can be adjusted.

4. Large pollution interception capacity: the pollution interception capacity is 2 to 4 times that of the general conventional filter.

5. Small floor space: The high-efficiency filter has compact structural design and small floor space.

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

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 polluted, we can clean it without replacing it. The general service life can be as long as 10 years.
