What is a dedicated fan for air shower room?

The dedicated fan for air shower is an indispensable and important part of clean room equipment, mainly used to ensure the air flow and clean effect in the air shower room. This article will analyze the definition, type, power, Air volume, voltage and other aspects of the dedicated fan for air shower in detail.

I. Definition of dedicated fan for air shower room

The dedicated fan for air shower is an air circulation equipment designed for air shower. Its main function is to generate strong airflow in the air shower and remove dust and microorganisms on the surface of personnel or objects through efficient air flushing. This fan can ensure the air quality of the Clean room environment and reduce the risk of cross contamination. It is an important guarantee for maintaining Clean room standards.

II. Types of dedicated fans for air shower

Dedicated fans for air shower are usually divided into the following types according to different design requirements and application scenarios:

1. Axial flow fan

The airflow direction of this fan is parallel to the axis of the fan, which is suitable for air showers that require large air volume and low air pressure. It has a simple structure and is easy to maintain.

2. Centrifugal fan

The airflow is at right angles to the fan axis and is usually used in situations where high air pressure is required. Centrifugal fans can provide stronger airflow impact and are suitable for large air shower applications.

3. High-efficiency filter fan

This fan is equipped with a high-efficiency air filter, which can further improve air cleanliness and is suitable for clean room environments with extremely high air quality requirements.

III. Power and air volume of fans dedicated to air showers

The power and air volume of fans dedicated to air showers are important indicators for evaluating their performance:

1. Power

: The power of the fan usually ranges from a few hundred watts to a few kilowatts. The specific selection should be determined according to the scale and use requirements of the air shower. The size of the power directly affects the operating efficiency and energy consumption of the fan.

2. Air volume

Air volume refers to the amount of air delivered by the fan per unit time, usually expressed in cubic meters per hour (m³/h). The design air volume of the air shower should meet the grade requirements of the clean room, usually between thousands and tens of thousands of cubic meters per hour.

The Air volume calculation formula for air shower room is:

Fan air volume = nozzle area × Wind speed × 3600 × number of nozzles

For example, if the nozzle diameter is 0.02 meters, the wind speed is 30 meters/second, and the number of nozzles is 12, the air volume is calculated as follows:

Air volume = (0.02)² ×π × 30m/s × 3600s/h × 12 h = 1627 m³/h

IV. Voltage of dedicated air shower room fans

The voltage specifications of dedicated air shower room fans usually have a variety of options to adapt to the power systems in different regions. Common voltage standards include:

1. Single-phase voltage

usually 220V, used for small air showers or lower power fans.

2. Three-phase voltage

Commonly 380V and 400V, suitable for large air showers or high-power fans. Three-phase power supply can provide more stable current and is suitable for long-term operation.

the fan for clean room air shower is a vital part of air shower equipment. Its type, power, air volume and voltage and other parameters directly affect the performance and effect of air shower. Choosing a suitable fan can improve the air quality of clean room and ensure the safety and sanitation of production environment. When designing air shower and selecting equipment, these factors should be fully considered to achieve the best balance between clean effect and energy efficiency.
