Double Person Air Shower

we will focus on one particular type of air shower: the double person air shower. We will explain its benefits, features, and applications, and show why it is the ultimate solution for contamination control in cleanrooms.

Double person air showers are an essential component of contamination control in cleanrooms, offering efficient and cost-effective removal of particles from the surfaces of people. They are suitable for a wide range of applications and offer several benefits over single-person air showers, including reduced waiting time, increased throughput, and space and energy savings. When selecting a double person air shower, it is important to consider factors such as the size and configuration of the cleanroom, the level of cleanliness required, and compliance with relevant standards and regulations.


1. What is a double person air shower?

A double person air shower is a type of airlock that accommodates two people at the same time, each standing on opposite sides of the chamber. The chamber is equipped with high-velocity HEPA-filtered air nozzles that blow air over the people from all directions, removing particles from their surfaces. The air is then filtered and recirculated back into the chamber, while the removed particles are collected in a pre-filter or a post-filter.


2. How does a double person air shower work?

A double person air shower works by creating a high-velocity air stream that removes particles from the surfaces of people who enter the cleanroom. The air shower chamber is equipped with multiple nozzles that blow air from all sides, top, and bottom, ensuring complete coverage of the people's bodies. The nozzles are located in the ceiling, walls, and floor of the chamber and are designed to produce a laminar flow of air that is free from turbulence and dead zones. The air is filtered through a HEPA filter with an efficiency of at least 99.99% for particles as small as 0.3 microns, which is the most penetrating particle size (MPPS) for HEPA filters.


3. Why is a double person air shower better than a single person air shower?

A double person air shower is better than a single person air shower for several reasons. First, it allows two people to enter the cleanroom at the same time, reducing the waiting time and increasing the throughput. Second, it reduces the risk of contamination by ensuring that both people are properly decontaminated before entering the cleanroom. Third, it saves space and energy by using a single air shower for two people instead of two single-person air showers. Fourth, it is more cost-effective than two single-person air showers. Finally, it is more convenient and practical for larger cleanrooms with high traffic.


4. Benefits of double person air showers

Double person air showers offer several benefits for contamination control in cleanrooms, including:

Efficient removal of particles from the surfaces of people

Reduced waiting time and increased throughput

Reduced risk of contamination by ensuring proper decontamination of both people

Space and energy savings compared to two single-person air showers
