What is the cycle time of an air shower?

An air shower is a widely used device in cleanroom environments, mainly used to remove dust and microorganisms from the surface of people or objects, thus maintaining cleanroom air quality and environmental hygiene. In this paper, we will analyze the blowing time of the air shower in depth and discuss its settings, influencing factors and effects.

I. Air shower blowing time setting

The blowing time of an air shower is an adjustable parameter, usually set between 0 and 99 seconds. The default blowing time is 15 seconds. This setting allows users to make flexible adjustments according to actual needs to meet the cleanliness requirements of different scenarios.

Factors affecting the blowing time of an air shower room

The blowing time of the air shower is closely related to a variety of factors, mainly including:

1. Air shower volume size

The volume of the air shower directly affects air circulation and airflow distribution. Larger air showers may require longer blowing times to ensure that every corner is effectively cleaned.

2. Cleanroom cleanliness Level Requirements

Different cleanroom levels require different levels of environmental cleanliness. For high class cleanrooms, such as ISO5, longer blowing times may be required to ensure that contaminants are minimized.

3. Number of people blowing in the air shower room

When a large number of people enter the air shower room at the same time, the air flow may be affected, so it may be necessary to extend the blowing time appropriately to ensure that all people can get sufficient air rinsing.

III. The two sides of air shower blowing time

The blowing time of the air shower is not only related to the cleanliness effect, there are also some advantages and disadvantages:

1. The longer the blowing time, the better the results

Appropriate extension of the blowing time can improve the effectiveness of air rinsing, more effective removal of contaminants attached to the surface of clothing and body. However, excessively long blowdown times may result in lower efficiency and affect production schedules.

2. The shorter the blowing time, the less effective it is

Although shortening the blowing time can speed up the flow of people and avoid congestion at the entrance of the flow of people, it may lead to unsatisfactory cleanliness and increase the risk of contamination in the cleanroom.

the cycle time of the air shower room is a parameter that needs to be flexibly adjusted according to the specific situation. A suitable blowing time can effectively improve the air quality of the cleanroom and guarantee the safety and hygiene of the production environment. Therefore, when selecting and setting the blowing time of an air shower, it is necessary to take into account the volume of the air shower room, the cleanliness requirements and the number of people entering the room, in order to achieve the optimal balance between cleanliness and work efficiency.
