What is the standard air speed of the air shower and how much is it necessary to achieve the best ef

The wind speed standard of the air shower room is 18m s according to the relevant specifications (specifically it should be the clean room specification, which can be found in the library), but now most manufacturers can reach it, and it is best to achieve more than 25m s to achieve the best effect;

The wind speed of the air shower room is mainly related to the internal configuration of the air shower room, including: fan, filter screen, etc., some air shower rooms have just been bought, and the wind speed can meet the requirements, but after two months, it may be significantly smaller, it may be that the fan is not good or the resistance of the high-efficiency filter is too large, so it is also necessary to examine this factor!

Technical parameters of the standard air shower:

Spray ball outlet wind speed: >20ms Interlocking method: electronic interlocking.

Filter Efficiency: Power supply: 380V, 50Hz three-phase.

In order to reduce a large number of dust particles brought by the entry and exit of people and goods, the installation of a fully functional "airlock chamber" at the entrance of the clean room can reduce the number of air pollution particles, when people and goods pass through the all-stainless steel air shower, the pollution particles are shot off by highly clean air filtered by high efficiency, and the high wind speed of more than 25m s ensures that the effective jetting and drifting particles are basically filtered out by the primary and high-efficiency two-stage filters.

Due to the installation of air circulation filtration system and lighting equipment, there will be a certain difference in the size of the air shower room. The external size of the air shower room is generally meters wide and high, and the inner size is meters wide and 2 meters high, which is just suitable for one person to pass through. The nozzles on both sides of the nozzle spray out a filtered clean airflow, and the wind speed from the air outlet to the person's body will be weakened, but it can still reach more than 18m s, which is equivalent to.

For level 8 and 9 winds, it only takes about 20 seconds to achieve the blowing effect. If it is too spacious, the wind speed will be weakened, resulting in wasted energy and ineffective results.

The depth of the air shower room, if it is suitable for 1 person, is 1 meter for the outer size and 1 meter for the inner size. If you want to accommodate more people at the same time, the width and height should remain the same, and the depth should be expanded appropriately. Generally, it can be extended to the outer size of the meter, the inner size of the meter, which can accommodate 5 people at the same time.

Stainless steel columns can also be set up in the tunnel type air shower concealment room, so that the blower personnel can only keep turning around when moving forward, forming an S-shaped route, and more body parts are exposed to the outside, and the dust removal effect is better. It can also be set up with multi-level induction to realize segmented start-up and man-to-wind start, which greatly saves energy and reduces the starting current. The width and height of the tunnel air shower are the same as those of the ordinary air shower.

The depth size varies from 4 meters to 10 meters, and can accommodate 8-20 people at the same time.

The wind speed standard of the air shower room is 18m s according to the relevant specifications (specifically it should be the clean room specification, which can be found in the library), but now most manufacturers can reach it, and it is best to achieve more than 25m s to achieve the best effect;

Hope it helps!

The general wind speed is 18-25m s for the rock shelter, and the detailed details can be consulted with the air shower room manufacturer.

As a purification equipment with strong local purification, the air shower room is usually controlled at about 25s, and the dust removal rate can reach the maximum. In the actual use process, the air shower room is located between the clean room and the non-clean room, and the use is frequent, and the resistance of the filter rises relatively quickly, so the factory wind speed of the air shower room is usually about 25s and can pass the acceptance. However, after using the filter for a period of time, as the resistance of the filter increases, the wind speed will decrease and the dust removal effect will also decrease.

All in all, how does a device work well and how do we use it? How to use it has a lot to do with it, and it is very necessary to learn to maintain and maintain it regularly. Common problems and maintenance skills of air shower room.

Hello, air shower.

The blowing time is adjustable between 0-99 seconds. It's just that it's generally about 15 seconds. Why 15 seconds? There are several reasons for this:

1.If the blowing time is too small, it may cause the dust carried by the human body or goods to be blown unclean.

2.If the blowing time is too long, it will cause too much consumption. If a large number of people need to pass through the air shower in the factory or company, it may not be possible to pass through the air shower within the specified time.

3.The value of 15 seconds is generally the most common in electronics factories, food factories, and pharmaceutical factories. Because of this kind of factory, the human body generally does not carry a lot of dust, and 15 seconds of blowing time is enough to blow the dust off the body!

Functions and characteristics of air shower room configuration: 1It adopts fully automatic control operation, double door electronic interlock, induction automatic blowing, and double door locking when blowing.

2.Cold plate spraying series, using multi-layer pickling technology, electrostatic dust-free spraying treatment. 3.

Stainless steel handles, thickened stainless steel base plates, and stainless steel nozzles are used as the basic configuration. 4.The digital display blowing time is adopted, the air shower time is 0 99s adjustable, and the air shower time is displayed.

5.The air supply air shower system designed with a new design concept can reach a super wind speed of 25m s and 32m s, ensuring that the personnel and goods entering the clean room can achieve the perfect effect of thorough dust removal. Air shower room structure:

1.The air shower chamber is composed of several major components such as box, door, high-efficiency filter, blower, distribution box, nozzle and so on. 2.

The floor of the air shower chamber is usually made of stainless steel, and the cabinet is welded with stainless steel or steel plate bending and welded with a milky white lacquer surface. 3. The box is made of high-quality cold-rolled steel plate, the surface is electrostatically sprayed, which is beautiful and generous, and the inner bottom plate is made of stainless steel plate to resist wear and friction, and it is easy to clean. 4. The main material and dimensions of the box can be customized according to customer requirements. ‍‍
