Air Shower Nozzle

In this article, we will discuss the concept of air shower nozzles, how they work, and their benefits in cleanrooms.

Cleanrooms are critical environments used in various industries, such as pharmaceuticals, electronics, and biotechnology, where the slightest contamination can cause catastrophic consequences. Contaminants can enter cleanrooms through various ways, including personnel, equipment, and materials. One effective method of controlling contamination is by using air shower nozzles. In this article, we will discuss the concept of air shower nozzles, how they work, and their benefits in cleanrooms.


Understanding Air Shower Nozzles

Air shower nozzles are devices used to remove contaminants from personnel or equipment before they enter a cleanroom. They work by blasting high-velocity jets of air from various angles, which dislodge and remove contaminants from the surface of objects. The air is typically filtered using HEPA filters to remove sub-micron particles and prevent their re-entry into the cleanroom.


How Air Shower Nozzles Work

Air shower nozzles consist of a chamber where personnel or equipment enters. Once the door is closed, jets of high-velocity air are blasted from nozzles located in the walls, ceiling, and floor of the chamber. The air velocity is typically around 25 m/s, which dislodges and removes contaminants from the surface of objects. The air is then filtered through HEPA filters and re-circulated back into the chamber.


Benefits of Air Shower Nozzles

Using air shower nozzles in cleanrooms has numerous benefits, including:


Improved Contamination Control

Air shower nozzles provide a highly effective method of removing contaminants from personnel and equipment before they enter a cleanroom. This reduces the risk of contamination and helps maintain the cleanliness of the cleanroom environment.


Increased Productivity

Air shower nozzles reduce the time required for personnel and equipment to enter the cleanroom. This can lead to increased productivity and efficiency in cleanroom operations.


Cost Savings

By reducing the risk of contamination, air shower nozzles can help prevent costly cleanroom shutdowns and product recalls. They can also reduce the frequency of cleaning and maintenance required in cleanrooms.


Types of Air Shower Nozzles

Air shower nozzles come in various types, including:


Single Person Air Shower

Single person air showers are designed for personnel to enter one at a time. They typically have a smaller footprint and are more cost-effective than larger air showers.


Tandem Air Shower

Tandem air showers are designed for larger equipment or multiple personnel to enter at once. They typically have a larger footprint and are more expensive than single person air showers.


Pass-Through Air Shower

Pass-through air showers are designed for the transfer of materials and equipment into and out of a cleanroom. They typically have doors on both sides and are useful in maintaining the cleanliness of the cleanroom environment during material transfer.


Considerations When Using Air Shower Nozzles

When using air shower nozzles, several considerations should be taken into account, including:


Location

Air shower nozzles should be strategically located to ensure maximum coverage of personnel and equipment.


Maintenance

Air shower nozzles should be regularly maintained and cleaned to ensure optimal performance.


Airflow

Air shower nozzles should be designed to provide consistent airflow and velocity to ensure effective removal of contaminants.


Air shower nozzles are critical devices for maintaining the cleanliness of cleanrooms in various industries. They provide a highly effective method of removing contaminants from personnel and equipment before they enter the cleanroom. When using air shower nozzles, it is essential to consider their location, maintenance, and airflow to ensure optimal performance. By utilizing air shower nozzles, industries can reduce the risk of contamination, increase productivity, and save costs associated with cleanroom shutdowns and product recalls.


In conclusion, air shower nozzles are a vital tool for contamination control in cleanrooms. They work by dislodging and removing contaminants from personnel and equipment before they enter the cleanroom environment. There are various types of air shower nozzles available, including single person, tandem, and pass-through air showers, each with their own unique benefits. When using air shower nozzles, it is essential to consider their location, maintenance, and airflow to ensure optimal performance. By utilizing air shower nozzles, industries can maintain the cleanliness of their cleanrooms, reduce the risk of contamination, and increase productivity and cost savings.

(1) Technical parameters and descriptions of conventional air shower nozzles

Design features: Design features Special structural nozzles designed for the air shower room (air shower channel), the wind ball can adjust the direction at a large angle, long-term resistance to large air volume, high wind speed (25 m/s), and can quickly blow away people and objects surface dust;

Material Description: There are stainless steel and ABS chrome-plated two materials to choose from.

(1) The stainless steel type is made of 304SS molded and stretched, polished to a mirror surface, no dust, no scratching balls, no air leakage, durable;

(2) The ABS type has a variety of metal coatings, the outer layer is chrome-plated, the cost is low, and the effect is comparable to the former.

Product application: general application in pharmaceutical, electronics, food, aerospace, chemical and other factories with cleanliness requirements

Main parameters: The maximum outer plate size of the nozzle is 165MM, the air outlet size is 30MM, and 38MM is optional; the plastic air shower nozzle provides three specifications: clamp connection, screw connection, and air duct direct connection. The maximum outer plate size of the nozzle is 165MM, and the air outlet is 30, 38 Two specifications of stainless steel embedded: outer diameter 165mm, caliber 30mm plastic chrome-coated embedded:


(2) Introduction of fully automatic rotatable air shower nozzles

The fully automatic rotating air shower nozzle effectively rotates the air in a large area, blowing and "rubbing" the dust-proof clothing like washing clothes, which can better reduce the dust adhesion of the dust-proof clothing and improve the cleanliness of the clean room; more Simple voice prompts, reducing voices such as "working, please turn your body 360 degrees", eliminating the need for employees to rotate their bodies and other cumbersome operations, and harmonizing the relationship between the company and employees; higher air speed, larger blowing area , Promote the overall performance of the air shower room.
