If you work in a cleanroom or a controlled environment, you know the importance of maintaining a clean and sterile environment. Contamination can cause severe damage to products and the reputation of the company. The use of air showers is an essential component in maintaining a clean environment, and the double blowing air shower is becoming increasingly popular. In this article, we will discuss everything you need to know about double blowing air showers, including its benefits, installation process, maintenance, and more.

1. What is a Double Blowing Air Shower?

A double blowing air shower is a type of air shower that uses two sets of nozzles to direct air towards the user. One set of nozzles directs air horizontally, while the other set directs air vertically. The combination of the two sets of nozzles provides better cleaning and decontamination of personnel and objects entering or leaving a controlled environment. Double blowing air showers are commonly used in industries such as pharmaceuticals, biotechnology, and electronics, where maintaining a clean and sterile environment is critical.

2. Benefits of Using Double Blowing Air Showers

Reduced Contamination Risk

One of the significant advantages of using double blowing air showers is the reduced contamination risk. The double nozzles direct air towards the user from multiple angles, ensuring that any contaminants or particles are removed from the individual or object. This helps to prevent contamination from entering the cleanroom or controlled environment, reducing the risk of product damage or recalls.

Improved Efficiency

Double blowing air showers are designed to improve the efficiency of the cleaning process. The dual nozzle system allows for better coverage and decontamination, reducing the time required to clean and decontaminate personnel and objects. This results in improved workflow and productivity.

Lower Operating Costs

Double blowing air showers can help to lower operating costs in cleanroom environments. By reducing the risk of contamination, companies can reduce the cost of product recalls and damage to equipment. Additionally, the improved efficiency of the cleaning process reduces the time required to maintain the cleanroom, reducing labor costs.

3. Installation Process

Pre-Installation Requirements

Before installing a double blowing air shower, it is essential to ensure that the area is suitable for the installation. The installation area should be free from any obstructions, and there should be sufficient space for the air shower and the personnel using it.
